ABSTRACT
The purpose of this paper
was to develop a reference model for the implementation of the process of
product development (PDP) for apparel. The tool was developed through an
interactive process of comparison between theoretical. Managers in companies
and professionals working in this market can utilize the reference model as a
source for the organization and improvement of the PDP for apparel and the
universities as a reference source for systematized teaching of this process.
This model represents the first comprehensive attempt to develop an instrument
at a detailed level (macro phases, phases, activities, inputs and outputs at
each stage and at the gates) to systematize the PDP process for fashion
products and to consider its particularities.
1. INTRODUCTION
Apparel
production is one of the industries with the most potential for exportation and
one of the oldest industries in the world. It is also one of the most global
industries because the majority of companies produce for the international
textile and apparel market (GEREFFI; FREDERICK, 2010). In the textile chain,
the apparel sector unites a large number of companies. However, it is the
sector with the lowest level of innovation compared with other links in the
textile chain. This fact originates from the production process, which demands
a large amount of manual labor. Besides the lack of innovation, apparel
industries mostly have low technical and managerial capacity (BNDES SECTOR,
2009). In view of these characteristics, it is essential for the industry to
innovate in product design, management
and operational processes to maintain profitability (SENANAYAKE; LITTLE, 2001).
The
paradigm of effective management in the apparel industry is related to the
prediction of consumer needs and desires. Accordingly, the companies in this
sector need to respond with innovation and products that are designed and
manufactured properly (DILLARD et al., 2000; MAY-PLUMLEE; LITTLE, 2006). These companies need to
develop and manufacture lines of high-quality, diversified and competitively
priced products (KWAK et al.,
2010). They also need to reduce the product development (PD) time
and manage employees effectively to meet these challenges (DILLARD et al., 2000). In this environment, in
which the competition is intense and dynamic, to dominate the market, a
company’s ability to conceive and design a great variety of quality products
faster than its competitors is instrumental (WHEELWRIGHT; CLARK, 1992). For
product development to meet these demands, the effective management of the
product development process (PDP) as a whole becomes an indispensable factor.
Because
of the competition, apparel manufacturers seek ways to be more flexible, more
efficient and better focused in their forecasting, production and sale of
products (KINCADE et al., 2007). The
dependence of the apparel industry on product
design makes the PDP faster, requiring the development of a large number
of products at the same time. May-Plumlee and Little (1998) present these
aspects as follows. First, the industry products are developed in seasonal
lines (collections) instead of as individual products. A line of apparel may be
constituted by different groups of products that should be managed
simultaneously with the process. Consequently, the process proves to be more
complex because some decisions made during the PDP have implications for the
entire product line, while others apply only to a limited number of products.
Second, several lines of new products should be produced per year. Third, the
strategy for the development of any product in the line of apparel may be
different from the strategy used in the development of other types of products
(MAY-PLUMLEE; LITTLE, 1998).
Due
to the specific aspects of the development of apparel products, they present
some individual characteristics. The creation of a methodology, a reference
model for the PDP, specific to the apparel industry and adapted to its
characteristics, is a way for these companies to structure their PDP,
increasing the performance of the development process and, consequently, the
companies’ market share. Other authors have proposed models for the product
development process for fashion wear; however, the stages throughout the
process and the relationships between them are not exploited, and the models
have proved themselves to be superficial.
This
study focuses on apparel companies that produce fashion wear and develop it in
collections throughout the year, the characteristics of which increase the
complexity of the PDP in this sector. The purpose of this research is to
propose a reference model for the process of apparel product development
(APDP). The developed model can be used as a reference for companies in the
sector to structure the PDP. The use of the model will allow apparel
professionals to systematize the stages of the PDP, resulting in a reduction of
the lead time. The model may also become the basis for researchers working in
the PDP, especially on research related to the apparel manufacturing industry,
and in fashion education institutions, design
and product engineering.
2. LITERATURE REVIEW
Product
development is a business process that aims to transform data and technical
possibilities into market opportunities and information, enabling and assisting
the development of product design (CLARK; FUJIMOTO, 1991). Krishnan and Ulrich
(2001) defined product development as the transformation of a market
opportunity into a set of assumptions about the technology of the product for
sale, in addition to being the main source of product and process quality. The
quality of the PDP management is closely linked to the standardization process
(AMARAL; ROZENFELD, 2007). A structured development process for new products is
essential for most businesses to reach their goals, to provide new products
continually to attain customer satisfaction (VALERI; ROZENFELD, 2004).
According
to March-Chordà et al.
(2002), one of the success factors in the development of innovative products is
the formalization and planning of the product development process. However,
many companies have difficulties in defining the most appropriate strategies to
achieve significant and sustained improvements. This is due to the complexity
of PDP technologies and procedures, which are often incompatible with the
degree of industry maturity (OLIVEIRA; KAMINSKI, 2012).
The
product development process has a multidisciplinary character, is
technologically complex and occurs at the intersection of different fields
(Revilla and Rodríguez, 2011. To deal with this fact and increase their
competitiveness, many companies are actually reviewing their product
development practices and implementing approaches that will enable them to cope
with increasing uncertainty and ambiguousness (KOUFTEROS et al., 2002). Thus, a documented and
systematic process provides the use of the best design practices and a single
and standardized language for the entire company. From the moment that this
process becomes standard and can be utilized by several people, it is
documented as a model (AMARAL; ROZENFELD, 2007).
The
formalization of the PDP management model allows an overview of all the
participants in the entire process (senior management staff of the
company’s functional areas and partners). Everyone involved in the
development becomes familiar with the expected results for the PDP, which
activities should be undertaken and how, which conditions must be met, the
source of information and the decision criteria to be adopted. As development
projects are defined from this model, it is known as a reference
model (AMARAL; ROZENFELD, 2007).
The
product development process can be defined as a set of phases (TROTT, 2008).
First, the new market opportunities have to be identified; second, they must be
evaluated in terms of technical and economic feasibility; third, new product
concepts have to be developed; fourth, these must be converted into physical
prototypes; and fifth, eventually, these prototypes must be converted into
products that can be marketed (GRUNERT et
al., 2011). Amaral and Rozenfeld (2007) presented a set of phases, executed
in a reference model that describes the process of developing new products
in various sectors, and this is the basis on which companies can develop this
process in accordance with a common point of view. The model is divided into
macro phases, namely pre-development, development and
post-development. Each macro phase is subdivided into phases and activities.
From
the literature concerning the development of apparel products, basic steps in
the process can be identified, such as research for the drafting of ideas,
conceptual lines and preparation for production and the market. Within each of
the four basic steps are countless design and development activities that are
carried out sequentially (KINCADE et al., 2007). Many authors, through their research, have developed
models for the PDP specifically for apparel (GASKILL, 1992; LAMB; KALLAL, 1992;
MAY-PLUMLEE; LITTLE, 1998; WICKETT et al.,
1999; RECH, 2002; MONTEMEZZO, 2003; PITIMANEEYAKUL et al., 2004).
3. METHODOLOGY
This
research is based on extensive examination of the development process of
the apparel product. The research is predominantly qualitative and of an applied
nature. Regarding the technical procedure, bibliographic research was
undertaken, as in the first stage of this work, studies of reference models for
the existing PDPs in the literature were necessary to support the development
of the proposed model (GASKILL, 1992;
LAMB; KALLAL, 1992; MAY-PLUMLEE; LITTLE, 1998; WICKETT et al., 1999;
RECH, 2002; MONTEMEZZO, 2003; PITIMANEEYAKUL et al., 2004;
ROZENFELD et al., 2006).
This is a case study, since the study investigates a phenomenon, the
case of the PDP in the apparel manufacturing industry. Having defined
the method, data collection was carried out by means of field research. The
data collection for this research was conducted in interviews with companies,
professors and professionals in the area of apparel, following May-Plumlee and
Little’s (1998) research.
For
the stratification of the sample of companies, the first criterion adopted was
that the companies would produce fashion products under their own brand and
that they would have an environment and a product development team in the
company. For the respondents in the sample of professionals, it was decided
that only those who worked directly with the fashion APDP and who were directly
involved in the whole process could participate. As for the professors, the
parameter for the stratification was that the individual would have to be
teaching or have already taught lessons in the discipline of apparel product
development on a fashion course or fashion design course at the higher education level.
The
script of the interviews was in the form of open questions, and it was
structured differently for businesses, professionals and professors. The
preparation of the script was undertaken after a bibliographic review of the
subject. However, the interviews had the same goal: to answer, regarding the
product development process, the questions of “what” the process is and “how”
it is performed, both from the companies’ and from the academics’ perspectives.
Analysis of the companies interviewed
Eight companies with their own
brands were interviewed, which performed the PDP internally and manufactured
fashion products, that is, they developed products through seasonal collections
and followed fashion trends. The characteristics of the companies that were
interviewed for topic exploration are presented in Table 1.

All
of the companies’ respondents were designers. This fact highlights the
importance of these professionals for the apparel PDP, since in most companies
these professionals are the PDP managers in charge of the process as a whole in
addition to the creation of the pieces.
The companies interviewed work through collections
(product lines). These collections are usually named after seasons (for
instance, summer, high summer, winter, autumn/winter), but each company employs
a different strategy regarding the number of collections and the number of
models developed by each collection. On average, the companies interviewed
develop three collections a year, ranging from 30 to 500 models each, depending
on the company.
The PDP of each company was mapped to gain a better
visualization and understanding of the phases and activities. The sequences of
activities that these companies undertake in the PDP do not display large
variations. In general, basically the same phases are performed, differing in
nomenclature, group activities and especially the degree of depth in which each
stage is conducted. The comparison among the stages developed by each company
can be seen in Figure 1.
Through this comparison, it was possible to identify
the phases that are similar in the product development process and the gates
(verification activities) that are utilized by the companies in the process.
Similar gates are displayed in the same color.
Similar activities are grouped taking into account nomenclature
variations and the breakdown of activities from the phases and gates, as shown
in the row marked “Stages”. The top-ten phases for PDP companies were
identified: planning, research, raw materials selection, development styles
(drawing), modeling, pilot run, development of the technical data sheet,
marketing of the collection, production and lauching. Through the modeling of
the PDP, it was also possible to group the activities and documents
generated in the process of the industries in a generic way. The gates used by
the companies were related to the decision-making process for the approval of
the theme, the approval of raw materials, the approval of sketches and the
pilot run apparel approval.
Figure 1: Comparison of
the phases of the companies’ PDP and their nomenclatures
Analysis
of the professionals who were interviewed
The questions in the script used for the interviews
with the professionals concerned the activities that make up the PDP, the
organization of the process and issues relating to the development and use of a
reference model for the PDP in the apparel industry. Interviews were conducted
with four professionals who work directly with the PDP in the apparel industry
and follow fashion trends.
Through the interviews, it was possible to
characterize the PDPs of the apparel according to the design of each
professional. The stages were mapped as well as the stages of the companies.
From the maps, it was possible to make a comparison between the stages reported
by each subject, as shown in Figure 2.
Eight main stages for the PDP were identified
according to the professionals, as shown in the “Stages” row: schedule
definition, research, sketches drawing, raw materials definition and selection,
modeling, pilot run production, development of the technical data sheet,
production. In addition, two gates were identified in the process: sketches
approval and pilot run approval. Through a comparison, it was possible to
identify the phases and gates common to all professionals. Similar activities
were grouped taking into account the variation in the nomenclatures and the
detachment of the activities from the phases and gates.
Analysis
of the professors’ interviews
In the interviews, the professors were surveyed about
the phases that make up the apparel PDP for the teaching process, about issues
related to the availability of materials in the PDP of the apparel industry and
about the development and use of a reference model for teaching the apparel
PDP. Eight professors were interviewed, who were teaching courses on apparel
PDP in institutions of higher education.
After the general information was collected, the professors were
questioned about the phases that comprise the PDP in the apparel industry.
Figure
2: Comparison of the PDP stages for the professionals and their classifications
In the analysis of the phases reported by the
professors, it was possible to identify the early stages of the process, such
as design, creation, market analysis, target audience analysis, definition of
the labor sector, preparation and organization of the mind for creating and
purpose of the collection. This characteristic of the teaching process is due
mainly to the fact that the professors themselves teach the discipline on
fashion and fashion design courses, in which professional training is more
oriented towards the early stages of the PDP.
4. PROPOSED APDP REFERENCE MODEL
This
chapter presents the proposal of a reference model for the conducting of the
PDP in fashion apparel companies. The development of the proposed model was
divided into three stages and entailed unifying the knowledge obtained from the
literature and the interviews and the experience gained by the author of this
study. In Stage 1, a theoretical description was developed for the APDP. In
Stage 2, a comparison was made of the theoretical description and the results
of the field research with companies, professionals and professors. In Stage 3,
both the architecture and the proposed reference model for the APDP are
presented.
4.1.
STAGE 1: Theoretical
representation of the APDP
The
phases of the generic models for Rozenfeld’s (2006) PDP and of the specific
models developed by Gaskill (1992), Lamb and Kallal (1992), May-Plumlee and
Little (1998), Wickett et al. (1999), Rench (2002), Montemezzo (2003) and
Pitimanneyakul et al. (2004) all served as references for the development of
the theoretical model for the apparel PDP shown in Figure 3.
The
model for the PDP of Rozenfeld et al. (2006) was the only generic model
selected to compose the structure of the theoretical model of apparel, because
it is a generic model with a high level of detail and breaks down the phases
into activities. Other specific models of apparel found in the national and
international literature were used. This is due to a lack of specific
literature on the apparel PDP; as a result, it was decided to utilize the
greatest amount of information possible instead of choosing only one model to
serve as a basis for the theoretical model.
Figure 3: Comparison of stages and
classifications of the generic PDP model and specific apparel models
The
development of Figure 3 enabled a comparison to be made between the phases of
the specific model and those of the generic model with the respective
classifications used by the authors. The arrangement of the phases of the
specific apparel models was based on the macro phases and stages of the model
developed by Rozenfeld et al. (2006). A general analysis of Figure 3 shows that
most of the specific phases of the apparel models, compared with the generic
model of Rozenfeld et al. (2006), are in the development macro phase and some
phases of the macro stage of pre-development.
Following
an examination of Figure 3, a theoretical model was proposed that, along with
the research results, provided the basis for the development of the model for
the apparel PDP, which is grouped into three so-called macro phases: (i)
pre-development, (ii) development and (iii) post-development.
The field research aimed to support the development of
the reference model; interviews were performed following three different
approaches: apparel manufacturing companies, professionals in the area and
professors of higher education who teach the discipline of apparel product
development. The interviews aimed to map the APDP in three different areas.
Table 2 shows the phases for the APDP included in each area of the field
research. The phases/activities were separated into three macro phases
defined in the theoretical representation.
In Table 2, it is apparent
that some phases are repeated in the three areas studied; however, some phases
are specific to a certain area.
Generally speaking, the
phases described by the professors showed greater variation in the stages of
pre-development and post-development. Specific phases of this area were
identified as, for example, the phases/activities of scenario outlining/target
audience analysis and definition of the work sector in the macro phase of
pre-development and the phase/activity of post-use (disposal) in the
post-development macro phase.

The various stages described by the professors show
the greater concern of the academics with the phases/development planning
activities and post-product development. This fact confirms the lack of
activities related to the planning of the collections, that is, the activities
that precede the development of the product itself, and the lack of concern by
the companies, in general, regarding the destination of their product after
sale or even the possibility of the environmental degradation that it may
cause.
The phases for the APDP that emerged from the field
research were grouped, excluding the stages that were repeated and separated,
according to the phases of the theoretical representation. It is possible to
identify four phases/activities in the outcomes of the interviews that could
not be identified or associated with any phase/activity of the theoretical
representation:
(i) Outline scenario/target audience analysis
(ii) Definition of the work
sector
(iii) Generation of ideas
(iv) Post-use (disposal)
The other phases/activities resulting from the
interviews coincided with activities or phases of the theoretical
representation. Another comparison that was necessary for the construction of
the reference model was related to the gates defined in the theoretical
representation and identified in the field research interviews. One can
identify two gates in the field of research that do not relate to any gates in
the theoretical representation:
(i) Selection of ideas
(ii) Approval of the raw material
Gate (i) is related to the selection of ideas
collected in the trend research phase. These selected ideas serve as
inspiration for the collection definition, in the creative process of the
development of models and in the selection of raw materials. Gate (ii) is
related to the evaluation and selection of the raw materials to be used in the
collection. The phases/activities and the different gates identified in the
comparisons above will be incorporated into the theoretical representation for
the construction of the reference model.
4.3.
STAGE 3: Reference
model for the apparel PDP (APDP)
The reference model for the apparel product
development process is shown in two versions, a macro version and an extended
version, with the details of each phase of the APDP. Figure 4 is a macro
view of the model, considering the macro phases, phases and gates.
Figure 4. Macro view of the reference
model proposed for the apparel PDP
According to the structure of the theoretical model,
the reference model shows the macro phases of (i) pre-development, (ii)
development and (iii) post-development and the phases of (i) collection
planning, (ii) portfolio product planning, (iii) market research, (iv) concept
definition, (v) details, (vi) pre-production, (vii) product launch and (viii)
monitoring the product/process. In Figure 4, the definition of activities,
detailing, pre-production and launching of the product are represented as
overlapping figures, since they must occur individually for each product of the
collection. However, some activities in the phases were modified and/or added
after comparing the theoretical representation with the PDP modeling collected in
the field research. Tables 3, 4 and 5 display the summary of each macro phase
of the APDP reference model.

The phases are explained separately in a detailed
version. This was created from the theoretical representation model, the field
research and an array of activities versus responsibility prepared by
the authors.
The areas involved in the apparel industry PDP are:
(i) top management, (ii) product development (PD), (iii) management of PD, (iv)
commercial, (v) marketing, (vi) purchasing, (vii) production, (viii) quality
and (ix) engineering. To achieve a good performance of the process and use of
the reference model for APDP, the utilization of cross-functional teams is
necessary. According to Rozenfeld et al. (2006), the development productivity
or the quality of the products developed and the speed of the response to
consumer demands depend directly on the use of cross-functional development
teams with strong leadership and strong active participation of experts from
various functional areas.
Pre-development:
Collection planning
The first phase of pre-development planning is
dedicated to the collection, ensuring the connection between the PDP and the
company’s strategic planning. During this stage, the parties involved in the
collection are identified and the needs and control indicators for the process
are identified. At this stage, the individuals in charge of the process are members
of senior management, commercial, product development (PD) and engineering.
Some activities include advising the marketing and the management of PD. The
starting point of this phase is associated with three sources of data inputs:
strategic planning, staff list and fitness data and past collections. The
graphic representation of this phase containing the activity flow is shown in
Figure 5.
Figure
5: Collection planning phase
At this stage, the scenario and the target audience
are analyzed for the definition of the work sector. These activities are
developed to identify new market opportunities or companies that want to change
their focus of work, companies that are developing a new brand or product line
or companies that are entering the market.
The activity of preparing the schedule is instrumental
in guiding the collection’s work team during the APDP, and it is the
responsibility of the company’s engineering department. The definition of
production strategies, marketing and sales made by the senior management aims
to guide the decision making throughout the development of the collection.
At the end of this stage, the top management evaluates
the decisions taken during the phase, and then this information is documented
in the COLLECTION PLAN, which contains the following information: collection
working team; to-do list; collection schedule; performance indicators; work
sector and target audience; definition of the production and sales volume;
definition of sales outlets; and collection budget estimate.
Pre-development:
Planning of the collection portfolio
The collection portfolio planning phase is in charge
of defining the grid pieces that will be developed in the collection. This
planning is important as it provides a direction for the creation of the
apparel collection as well as making the planning of the sales of the
collection possible.
The COLLECTION PLAN information provides support for
the definition of the size grid, the type of apparel that will be developed and
the quantity of collection products by type and size. These activities are
developed jointly by the DP and the commercial team, then this information is
evaluated by the senior management and documented by the commercial team, which
updates the COLLECTION PLAN with the information generated during the phase.
The graphic representation of that phase with the activity flow is shown in
Figure 6.
Figure 6: Planning phase of the product
portfolio
Development: Research
the market trends
In this stage of researching the market trends, the
consumer needs and market trends for fashion apparel are investigated. The
trends in models, fabrics and trims, and colors for the collection are
researched, then the management of DP evaluates this information. With this
research, the DP defines the style specifications and sets the theme for
the collection that will later be evaluated by the senior management.
Regarding the output, the style information and theme
for the collection are documented in the TRENDS PLAN. In addition to the DP,
the DP management and the senior management as well as the commercial and
marketing teams provide support for these activities. The graphic
representation of that phase with the flow of activities
is shown in Figure 7.
Figure 7: Phase for the
research of market trends
Development: Definition
of the concept
The objective of the concept definition phase is to
develop the collection’s apparel alternatives. The graphic representation of
this phase with its flow of activities is shown in Figure 8. It is in this
phase that the designers have the freedom to create the outline of the apparel
for the collection, through manual or computerized drawings. The designer needs
extra time to create the number of apparel items, more than is planned in the
collection plan, so that, after assessing the collection, it does not become
depleted.
Figure 8: Concept
definition phase
After the creation of sketches, the DP selects the fabrics
and trims that make up the collection. This selection is evaluated by the top
management, and the raw material to be used is defined. The raw material is
linked to the sketches, which then undergo a preliminary study on the economic
feasibility of the piece. With the drawings and the initial economic
feasibility information, they are evaluated by the senior management.
In this phase, information is generated about: manual
style drawings and/or computerized products, the raw material to be used by the
products created, a list of suppliers, the development of a style data sheet
and a price quotation for each of the collection’s products. The information is
documented in the CONCEPT PLAN. In addition to the DP, senior management and
engineering, this phase counts on the help of commercial and PD management.
The detailing phase aims to identify the
specifications of the apparel designed in the concept definition stage and to
develop pilot apparel. The graphic representation of that phase along with its
activity flow is shown in Figure 9.
Figure 9: Detailing phase
In this stage, the company’s quality department
performs the raw material assessment to ensure final product quality and
generate information that will support the construction of the mold of the
apparel. The engineering department develops the architecture of the pieces
through the style drawings developed in the previous phase; the development of
technical drawings and detailing of the apparel are critical to the
construction phase of the pilot apparel and aim to avoid misinterpretations in
subsequent stages.
The DP department develops the pilot apparel, performs
fit testing, usability and ergonomics, develops the operational sequence of
each piece and develops the sizing of the approved apparel. The engineering
department develops the technical file for each apparel item and monitors the
economic feasibility of the apparel. Subsequently, the senior management
evaluates and approves the pilot apparel, considering the margin of the pieces
that were planned in the pre-development phase.
In this stage, the outcome of the work is the
technical specifications, packing specifications, product price update and mold
block. The technical specification data sheet provides a breakdown of the
products containing the piece of architecture, the operational sequence with
the stages of the manufacturing process, the technical design in scale and the
specifications of the raw material and production.
Development: Pre-production
The pre-production phase aims to develop and refine
the manufacturing processes to meet the collection needs. At this stage, the
raw materials are also purchased for the collection and the showcases for sales
representatives are produced. The graphic representation of that phase along
with its activity flow is displayed in Figure 10.
The acquisition of the raw material is the purchasing
department’s responsibility. The showcases for sales representatives are
produced, in the case that the company works with this type of sale, and this
activity is the responsibility of the engineering and commercial departments.
The engineering department establishes, in a definite way, the price for the
apparel. Furthermore, it calculates, along with the production department, the
resources necessary to produce the collection. The engineering department is
responsible for the development and optimization of the manufacturing
processes.
Figure 10: Pre-production phase
To provide support for new sales and production
processes, training is promoted by the engineering department for production
and by the commercial department for sales. Following the training, the
production of the apparel is released by the engineering department, which makes
its judgment based on the previous sales or the estimates produced together
with the commercial department. In addition to the purchasing, commercial,
engineering and production departments, the pre-production phase is advised by
the DP and DP management. After this phase, the following are achieved: the
showcase for sales representation, definition of costs, prices and profits of
the apparel, installed production resources, trained labor force, manufactured
products or production in progress.
Development: Launching
of the collection
The collection launch phase aims to insert the product
into the market. This phase involves the planning of the sales and distribution
processes and of the marketing campaign. In this stage, the marketing
department’s task is to plan the marketing campaign of the collection, launch
the collection and promote and manage the launch. Both the commercial and the
marketing department are in charge of the launching of the collection. The
senior management evaluates the marketing planning for the collection.
The outcome of this phase is the launch plan along
with the sales promotional material (catalogs, outdoors, lookbooks, banners,
etc.), the sales processes and the directions for launching the collection in
the wholesale and retail markets. The graphic representation of this phase
along with its activity flow is shown in Figure 11.
Figure
11: Collection launch phase
Post-development:
Monitoring of the product/process
The objective of the stage of monitoring the
product/process is to monitor, document and handle post-release information and
encourage and assist with the adoption of appropriate practices for the
disposal of products. The graphic representation of this phase along with its
activity flow is shown in Figure 12.
Figure
12: Product/ process monitoring phase
The outputs at this stage are the collection
performance report, registration and evaluation of the lessons learned,
customer satisfaction evaluation, product replacement and, if needed,
encouragement and partnership services for conscious practices for the disposal
or recycling of products. Those involved in this stage are the DP and sales and
marketing departments, with the assistance of DP engineering and management.
Eight gates were established (stage reviews) for the
APDP reference model. The decision making throughout the APDP course aims to
filter ideas or products that should move forward in the process. According to
Rozenfeld et al. (2006), “… the introduction of systematic formalized Gates is
a practice that brings great benefits to the company’s performance.”
The following describes each one of the gates of the
process:
·
Evaluation of the
strategies for the collection – To evaluate the strategies
that will guide the decisions regarding production,
marketing and sales throughout the development of the collection. The
senior management, supported by the areas of PD management, sales and
marketing, gives its approval.
·
Evaluation of the final
grid – To evaluate the
collection products’ grid, defining which products will be developed and their
quantities. This evaluation is approved by the senior management, supported by
the PD management.
·
Selection of ideas – Selection of the ideas collected and developed during
the research on trends, raw materials and colors for the collection. These
ideas form the basis of the development of the theme of the collection and are
approved by the PD management, supported by PD, sales and marketing.
·
Evaluate the theme – To evaluate the theme of the collection, defined by
the trends research. This is approved by the senior management, supported by
sales.
·
Filter the raw material – To refine the raw material
selected for the collection. This is approved by the senior management, supported by the PD
management.
·
Filter the models – To refine the models created
that are still in drawings, excluding or redoing some drawings. Approval is given by the senior management, supported by the PD management, sales and marketing.
·
Evaluate the pilot
apparel – To evaluate the models in physical form, known as pilot apparel. In this
stage, the apparel can be discarded or undergo changes in the modeling, raw
materials or production process. This
process is approved by the senior
management, supported by the PD management and assistants.
·
Evaluate the
collection’s marketing campaign – To assess the marketing campaign designed for the collection. In this
stage, the senior management, supported by the PD, PD management, sales and
marketing areas, evaluates whether the marketing campaign developed faithfully
represents the proposed theme for the collection and then continues with the
launching of the collection.
The execution of the gates is a joint activity and occurs through
meetings. The designated time for carrying out such meetings is an investment
that the company performs during the development of the collection. Such
meetings should be planned to avoid dispersion resulting from the contribution
of various individuals involved in the process (Rozenfeld et al., 2006). Whereas most apparel
companies are small, meetings regarding gates
can be held by a small group, considering that the fact that some people
may assume different roles in the PDP.
5. FINAL CONSIDERATIONS
The structure of the reference model proposed for the fashion apparel has
macro phases, phases, activities and inputs and outputs at each stage. The
possibility of the greater detail presented in this reference model justifies
the relevance of this work to the academic and business world.
Field research revealed that the main difficulties of APDP, acknowledged
by businesses and professionals, were related to the lack of organization of
the activities performed during the process, the difficulties in the
relationships between departments, the lack of time for a research stage for
trends and the definition. All these problems mentioned by the respondents can
be resolved with better planning and structuring of the PDP. For the professors
interviewed, the greatest difficulties were related to the lack of material
available on the APDP, at all stages. The development of the reference model
comes from encountering the difficulties reported in interviews and many other
APDPs faced in the course of the day-to-day work, be it in business or
academia, contributing to the design process and the lack of research in the
area.
The reference model for the APDP was developed considering the
particularities of the development of fashion apparel products, such as the
development of products in seasonal lines (collections) instead of individual
products, the development of several collections each year and therefore a
short period of time for the development process of each collection. Once the
structure of the model was presented in a simple way, the necessary dynamism
for the APDP was not compromised by the great amount of activities and
bureaucracy in the process.
It was also considered that the APDP characteristics are important and
that the proposed model was not developed with the goal of being a single
standard for the process, but as a combination of good practices that can be
used in its entirety to structure the APDP with flexibility or used partially
by means of adaption, adjusting to the reality in which it is employed. In this
case, the reference model is now called the adapted model.
