Product Design & Development

,Part 1
We will focus on the functional and ergonomic design aspects of textile products. We will
learn about the design basics. The analysis needs metric matrix development, development
of specifications, concept generation product architecture and use of natural analogy. There
will be some practical examples or case studies on technical product development. The
product development or product designing team is the core team. Marketing professionals
also become a part of this team then comes manufacturing engineers or actual production
people. Purchasing specialist is purchasing specialist which means people try to procure the
different kinds of raw materials that we need to design a product. Finance people can
suggest the availability of financial resources. The cell person has a direct link with the
customers. The rest of the people have no idea about the customers, no characteristics,
what the customers are looking for and how to sell the product. Product development
decisions have to be made very very fast because your competitors are otherwise going to
introduce a new product and therefore time pressure also will always be there like in textiles,
especially in the fashion market.
Part 2
There is a lack of design culture in textile industries, as there is a diversity of fibres that are
available now. Textile products are now finding applications in demanding areas, which
require engineering data for the design. Planning is there, and the plan has to be approved
before we move forward to the next step. After developing a concept of the product, we go
to the concept review.
A review exercise is very very important in the development process so specification review
is over so specifications are frozen temporarily. A prototype development process starts.
Products will be tested initially. We test them in the laboratory to see how it is going to
perform and we can depending upon the products we may also go for field trials. After that,
the actual production approval comes from the top management. The detailed design
aspects are then looked into critically and if required these are changed and again another
prototype is built and again tested. After a few iterations, the performance is again now
checked and once the approval is taken from the top management and it goes for
, commercial production this is how the steps are it is the previous one. The first step of the
design process is the planning phase; the first stack is the identification of opportunities.
The second stack is the evaluation and prioritisation of projects. The next step is the
allocation of resources in the planning part itself and the timing for lunch. Also, we have to
decide so that we have a time frame we set up that will take two years to design.
The most important thing is to document customer frustration and complaints. When
customers are not satisfied with existing products, we need to understand why they're not
satisfied. The demand for consumer goods will change as lifestyle changes, demographic
demographics changes, thermographic, and other things track the status of emerging
technologies. Customers focus on new and existing customers to assess their changing
needs and preferences and develop products accordingly. Many products have been seen to
have a safe trajectory of development of the product so when some companies decide that
this is a new technology which is coming, then they incorporate it into the design of their
product. If the performance is not going to change much then there is no point in continuing
with this existing technology.
The project statement must give you or must contain what target market the key business
goal is in terms of cost quality, financial performance or market share. The third one is some
description of the product very generally mentioning that customers benefit. These are the
three aspects which should be there in a paragraph where we will write the title of the
project. Sustainability is becoming very very important throughout the world so and
sometimes it is becoming a very you know selling point also that we are you can say that I
am developing a sustainable product i am going to save so much of energy is not going to
pollute the environment. Be kept in mind for some products during development. We have to
get it from abroad or import it so whenever we try to import something it is constant
because importing always means there is a time lag and sometimes things may be available
in time and sometimes may not be available. The stakeholders are young customers,
production engineers and the distributor's retailers' shareholders, all of them are basically
stakeholders in it.
