Abstract
The effective service design can be achieved by implementing collaboration work from domain experts and customers. This research depicts a conceptual service design framework: design-oriented systematic inventive thinking (DSIT) which can be applied in different problem contexts. It divides the real world design scenarios into four dimensions, and then provides the fitting integrated service design approach based on TRIZ. Four types of service design approaches have been suggested, conceptualized as 'Human-independent service engineering', 'Problem-clarified service engineering', 'Solution-converged service engineering' and 'Designing for services'. Regardless of any industries or companies, we can use this procedure to analyze and develop the suitable customized service design strategy for them.
