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

The Iceberg Secret
Design is the product
“[Design is] not just
what it looks like and
feels like. Design is how
it works.”– Steve Jobs

Be Empathetic with User
Design and Engineering Module-5: Product Centered Design and User Centered Design
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
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.

Design and Engineering Module-5: Product Centered Design and User Centered Design
People interact with a computer as
they would with another person
Every piece of interaction makes you
feel something
Design your product to be
a good human being
Be considerateandresponsive
“Perfection is
attained not when there
is nothing more to add,
but when
there is nothing
to remove.”
– Antoinede
Saint Exupéry

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
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

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.
• 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?
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.
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
Traditional Design
evolved through
Innovative ideas Modern Design
evolved through
technology
Modern design
with traditional
influence
Designs from tradition

Design and Engineering Module-5: Product Centered Design and User Centered Design

  • 1. DESIGN & ENGINEERING BE-102 Naseel Ibnu Azeez.M.P Asst. Professor, Dept. of Mechanical Engineering, MEA-Engineering College, Perinthalmanna. Email: naseel@live.com Module-5 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
  • 14. Design is the product
  • 15. “[Design is] not just what it looks like and feels like. Design is how it works.”– Steve Jobs
  • 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
  • 29. “Perfection is attained not when there is nothing more to add, but when there is nothing to remove.” – Antoinede Saint Exupéry more
  • 30. Discus the ergonomic and user centered considerations of these two smart phones Why the position of Power button changed in this model ?
  • 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
  • 39. Traditional Design evolved through Innovative ideas Modern Design evolved through technology Modern design with traditional influence
  • 41. Evolution of Wet Grinder
  • 42. MOTIFS AND CULTURAL BACKGROUND
