Some products or services will function as designed only within a narrow range of conditions,while others will perform as designed over a much broader range of conditions.The latter have robust design.The more robust a product or service, the less likely it will fail due to a change in the environment in which it is used or in which it is performed.Hence, the more designers can build robustness into the product or service,the better it should hold up,resulting in a higher level of customer satisfaction.
A similar argument can be made for robust design as it pertains to the production process.Environmental factors can have a negative effect on the quality of a product or service.The more resistant a design is to those influences,the less likely is a negative effect.
The Degree of Newness
Product or Service design change can range from the modification of an existing product or service to an entirely new product or service:
1.Modification of an existing product or service
2.Expansion of an existing product line or service offering.
3.Clone of a competitor’s product or service
4.New product or Service.
The degree of change affects the newness to the organization and the newness to the market.For the organization and the newness can mean a fairly quick and easy transition to producing a new product,while a high level of newness would likely mean a slower and more difficult, and therefore more costly,transition. For the market, a low level of newness would mean little difficulty with market acceptance, but possibly low profit potential.A high level of newness,on the other hand, might mean more difficulty with acceptance,or it might mean a rapid gain in market share with a high potential for profits.Unfortunately, there is no way around these isssues.It is important to carefully assess the risks and potential benefits of any design change,taking into account clearly identified customer wants.
