Product Centered & User Centered Design
Concurrent Engineering, Reverse Engineering
Tradition and Design, Cultural Influence On Design

2. USER CENTERED DESIGN
User-centered design (UCD) is a framework of processes in which the
needs, wants, and limitations of end users of a product, service or
process are given extensive attention at each stage of the design
process

3. What is ?

4. Not this

5. Nor this

7. NopeNo

8. This is Google

13. The Iceberg Secret

14. Design is the product

15. “[Design is] not just
what it looks like and
feels like. Design is how
it works.”– Steve Jobs

18. Be Empathetic with User

20. KEY PRINCIPLES OF UCD
I. The design is based upon an explicit understanding of users, tasks and
environments.
II. Users are involved throughout design and development.
III. The design is driven and refined by user-centered evaluation.
IV. The process is iterative.
V. The design addresses the whole user experience.
VI. The design team includes multidisciplinary skills and perspectives
The chief difference from other product design philosophies is that user-centered design tries to optimize
the product around how users can, want, or need to use the product, rather than forcing the users to change
their behavior to accommodate the product

21. USER INTERFACE (UI)
The user interface or human–machine interface is the part of the machine that handles the
human–machine interaction. Membrane switches, rubber keypads and touchscreens are examples
of the physical part of the Human Machine Interface which we can see and touch.

25. People interact with a computer as
they would with another person

26. Every piece of interaction makes you
feel something

27. Design your product to be
a good human being

28. Be considerateandresponsive

29. “Perfection is
attained not when there
is nothing more to add,
but when
there is nothing
to remove.”
– Antoinede
Saint Exupéry

31. VALUE ENGINEERING
Value engineering (VE) is systematic method to improve the "value" of goods or products and
services by using an examination of function.
Value, as defined, is the ratio of function to cost. Value can therefore be increased by either
improving the function or reducing the cost.
It is a primary tenet of value engineering that basic functions be preserved and not be reduced
as a consequence of pursuing value improvements
Value =
Worth
Cost
=
Function(Utility)
Cost
Value is the lowest price you must pay to provide a reliable function or service

32. WHY DO PROJECTS HAVE “UNNECESSARY” COSTS?
1. Low Time for Designing
2. Lack of information
3. Lack of Ideas
4. Negative Prejudice
5. Lack Of Experience
6. Weaknesses in human relations
7. Multi Concept
Waste Cost

35. 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.

36. • Competitive Advantage- reduction in time to market means that businesses gain an
edge over their competitors.
• Enhanced Productivity- earlier discoveries of design problems means potential
issues can be corrected soon, rather than at a later stage in the development
process.
• Decrease Design and Development Time- make products which match their
customer’s needs, in less time and at a reduced cost
Why concurrent engineering?

37. REVERSE ENGINEERING
Reverse engineering, also called back engineering, is the processes of extracting knowledge or
design information from anything man-made and re-producing it or re-producing anything based
on the extracted information.
The process often involves disassembling something (a mechanical device, electronic component,
computer program, or biological, chemical, or organic matter) and analyzing its components and
workings in detail.

38. TRADITION & DESIGN
Design between Tradition and Innovation explores the
relationship between tradition and innovation in
contemporary design around the themes of materials,
construction, configuration, production, and traditional use
