Design is how it works. Steve Jobs</p> <p>Be Empathetic with User </p> <p>Key principles of UCDThe design is based upon an explicit understanding of users, tasks and environments.Users are involved throughout design and development.The design is driven and refined by user-centered evaluation.The process is iterative.The design addresses the whole user experience.The design team includes multidisciplinary skills and perspectives</p> <p>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</p> <p>User interface (UI)The user interface or humanmachine interface is the part of the machine that handles the humanmachine interaction. Membrane switches, rubber keypads and touchscreens are examples of the physical part of the Human Machine Interface which we can see and touch.</p> <p>People interact with a computer asthey would with another person </p> <p>Every piece of interaction makes youfeel something </p> <p>Design yourproducttobeagoodhumanbeing </p> <p>Beconsiderateandresponsive </p> <p>Perfection isattained not when there is nothing more to add, but whenthere is nothingto remove. Antoine deSaint Exuprymore</p> <p>Discus the ergonomic and user centered considerations of these two smart phones Why the position of Power button changed in this model ?</p> <p>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. </p> <p>It is a primary tenet of value engineering that basic functions be preserved and not be reduced as a consequence of pursuing value improvements</p> <p>Value = WorthCost= Function(Utility)CostValue is the lowest price you must pay to provide a reliable function or service </p> <p>Why do Projects have Unnecessary Costs?1. Low Time for Designing2. Lack of information3. Lack of Ideas4. Negative Prejudice5. Lack Of Experience6. Weaknesses in human relations7. Multi ConceptWaste Cost</p> <p>32</p> <p>Concurrent EngineeringConcurrent 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.</p> <p>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 customers needs, in less time and at a reduced costWhy concurrent engineering?</p> <p>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.</p> <p>Tradition &amp; designDesign 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</p> <p>Traditional Design evolved through Innovative ideasModern Design evolved through technology Modern design with traditional influence </p> <p>Designs from tradition </p> <p>Evolution of Wet Grinder </p> <p>Motifs and cultural background</p> <p>FrenchItalianChineseAmerican</p> <p>Cultural Fusions in Design</p> <p>www.slideshare.net/naseelazeeniya</p>
