3. Product Design
The definition of product design describes the process of imagining, creating,
and iterating products that solve users’ problems or address specific needs in a
given market.
The key to successful product design is understanding the end-user customer,
the person for whom the product is being created. Product designers attempt
to solve real problems for real people by using empathy and knowledge of their
prospective customers’ habits, behaviors, frustrations, needs, and wants.

4. Product Development
Product development is the processes required to bring a product from being a
concept through to reaching the market. There are many steps required to take a
product from the early stages in the product development process, from product
idea generation and market research through to research and development,
manufacturing and distribution.

5. Objectives Of Product Design
The objectives of designing the product may be summarized as follows:
● The first objective of designing is to create attention in products for
increasing the sale potentials.
● To enlarge the importance of product from customers’ point of view.
● To make the product more effective and create more utility in the product
for the consumer.
● Produce better quality at the lowest possible price.

6. Engineering Design Process
The engineering design process is a
series of steps that engineers
follow to find a solution to a
problem. The steps include problem
solving processes such as, for
example, determining your
objectives and constraints,
prototyping, testing and evaluation.

7. Product Design VS Product Development
Product Design
Product design consists of all the designing activities. These enable the designer
to create the look and feel of the product. These include deciding the architecture
of the product and choosing the required materials. It is also important to
understand the best design that will suit the customer.

8. Stages of Product Design
1) Ideation
2) Feasibility study
3) Preliminary design
4) Testing
5) Product launch

9. Product Design VS Product Development
Product Development
Organizations have to come up with new ideas and new designs for their
products. This is to maintain its position in the market. Product development is
the complete cycle of all such steps. This starts from the conceptualization to the
product deployment. The main goal of the product development process is to
develop products according to customer requirements.
This will, in turn, increase the market share of the company. But every product
might not satisfy all customer demands. So, companies carry out a thorough
analysis of their customer base. This helps them to identify their target market
and develop products accordingly.

10. Stages of Product Development
1) Idea Generation & Screening
2) Concept development
3) Business analysis
4) Product development
5) Test marketing
6) Commercialization

11. Role Of Product Designer
● Making product sketches by hand or by using software
● Meeting clients and other employees to discuss the design
● To work with product developers, engineers, and marketing staff
● A designer also has to work with the finance team
● Modifying the design based on the feedback received during the
development stages
● They also analyse designs of other companies and help in generating new
ideas

12. Role Of Product Developer
● They analyze sales data, customer feedback, and product reviews. They also
assess their competitors products
● Consulting the manufacturing, design, finance and engineering team to
develop product specifications
● Supervising the final design and evaluating the prototype
● The developer submits proposals to the project head for reviewing. This
enhances the development process
● The product developer prepares the final cost estimates for the product

13. Features of successful Product Design
There are several aspects and nuances of a successful product design, Designers need
to keep in mind some important factors while conceptualising a product
Product design is an essential part of developing an idea into a viable, marketable
product. It involves creating new products or refinement of existing designs to
improve the functionality, performance and appeal. It also entails checking the
design, eliminating flaws and planning towards making a better product.
Product designers should have a sharp business mind, a strong eye for aesthetic
appeal, and the ability to analyse feedback.

14. Utility:
Utility is the foundation of customer needs. The first thing that a buyer considers while evaluating a
product is whether it satisfies his or her needs or not. A product can be successful only if it ensures
market acceptance and usefulness. Every component of the design should be able to serve a valuable
purpose. Any aspect of design that is not beneficial to the user can detract from the user experience
of the product.
Aesthetically relevant:
Aesthetics plays an important role in the future of product design. It brings up a positive attitude in
the users. The product needs to be functional and easy-to-use while at the same time it should
possess aesthetic power. This is because people want products that do wonders, while not looking
ugly. Imagine all the Apple fans. The same goes for digital products such as software, apps or
websites. A designer who wants to keep improving and developing skills should never miss out on
aesthetic sense.
Some Key aspects to keep in mind while designing a
product.

15. Simplicity:
As said by German Industrial Designer Dieter Rams, “Good design is as little design as
possible”. Therefore, simplicity plays a vital role in product design as much in life.
Crafting something simple and functional allows people to immediately understand
what the product does and how they can use it. A good product designer must always
showcase aesthetic ability, functionality and instinctive simplicity. Without simplicity,
a product will never be able to attract consumers.
Innovative:
Products should offer something new and revolutionary to connect with the
consumers. A better-looking product will win over the users immediately. Product
designers should focus on the desires of end-users, business goals and the available
technology to develop an innovative product.

16. Longevity:
Good product design never goes out of style. Good design is timeless, and if a
product is well-designed, it will last for long. Long-lasting and sustainable
products are more valuable, better for the planet, and are a testament to the
skills of the designer. Antiques, vintage clothing, old cars — these things are
still with us today because the people who designed them built them to last.

17. Modern Approaches to Product Design
1) Concurrent Design or Concurrent Engineering
2) QFD (Quality Function Deployment)
3) Rapid Prototyping

18. Concurrent Design or Concurrent Engineering
Concurrent engineering, also known as
simultaneous engineering, is a method of
designing and developing products, in
which the different stages run
simultaneously, rather than consecutively.
It decreases product development time and
also the time to market, leading to improved
productivity and reduced costs.

19. Quality Function Deployment (QFD)
Quality Function
Deployment (QFD) is a
process and set of tools
used to effectively define
customer requirements and
convert them into detailed
engineering specifications
and plans to produce the
products that fulfill those
requirements.

20. Rapid Prototyping

21. Product Development Team
A product development team is a group of people who oversee the
process of a new product design. Each member of the team
collaborates with the others to create and implement a strategy.
They also work independently to contribute to the overall goal,
which is to take the product to market. Types of jobs associated
with product development include:

22. ● Management: Product management involves creating a vision, developing a
strategy and implementing a plan for the new product.
● User experience (UX): UX professionals monitor how users interact with the
product by creating product drafts, doing research and testing usability.
● Analytics: Product analysts research trends in the market to gather
information about what consumers want and how they decide on a product.
● Marketing: Product marketers determine a target market for the product, help
the team create a launch plan and decide on the positioning and messaging
of the product.
