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

Design is the product
“[Design is] not justwhat it looks like and feels like. Design is how it works.” – Steve Jobs
Be Empathetic with User
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.
People interact with a computer asthey would with another person
Every piece of interaction makes youfeel something
Design your product to bea good human being
Be considerateand responsive

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 =
WorthCost
= 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
