WHY STUDY DESIGN?
• Exploding Knowledge including Technology• Dissolving Global Boundaries (Nobel Laureate Thomas Friedman,
“World is Flat”) and the acceleration of globalization ascompanies develop globally integrated organizations
• More demanding customers for all goods and services• Changing industry structure, including mergers and acquisitions
and a new order of manufacturer / supplier relationship assuppliers take increased responsibility for the design of parts,modules and systems
• A profound and rapidly growing role for information technologyin all its forms
• Intensifying competition• Time pressure that demands more, better yet faster results

Taga : a bike and a stroller
• When you first see the Taga you wonder why nobody thoughtof this sooner?
• Taga was developed by a team of industrial designers andmechanical engineers over a period of four years. The frameis made from aluminum alloy which is strong enough to carryheavy loads and it has internal Shimano gears and front andrear brakes.

Modern Trends in the Design
• Companies are collaboratingglobally in the effort to leveragetechnology, knowledge, humantalent and other resourcesnecessary to innovate andcompete
• “Global collaborative enterprises“- use of "mirror zones" enablingaround-the-clock, 24-hour productdesign and developmentcapabilities

Design
• Taylor (1959): Engineering design is the process ofapplying various techniques and scientificprinciples for the purpose of defining a device, aprocess, or a system in sufficient detail to permitits physical realization.
• Asimow (1962): Engineering design is a purposefulactivity directed towards the goal of fulfillinghuman needs, particularly those which can be metby the technology factors of our culture.
• Feilden (1963): Mechanical engineering design isthe use of scientific principles, technicalinformation and imagination in the definition of amechanical structure, machine or system toperform pre-specified functions with themaximum economy and efficiency.
• Kesselring (1964): Designing means to find atechnically perfect, economically favorable andesthetically satisfactory solution for a given task.

• Booker (1964): Simulating what we want tomake (or do) before we make (or do) it asmany times as may be necessary to feelconfident in the final result.
• Archer (1964): A goal-directed problem-solving activity.
• Reswick (1965): A creative activity -- itinvolves bringing into being something newand useful that has not existed previously.
• Hansen (1966): Developing a technicalconstruct is determined through prior visualthinking out.
