Function Analysis Plus and Cause-Effect Chain Analysis Plus with Applications
Abstract
In an inventive problem-solving project, the most important steps are often problem analysis and idea generation. Recently, two practical methods for these steps were introduced by the Korean consulting industry—Function Analysis Plus (FA+) and Cause-Effect Chain Analysis Plus (CECA+). This chapter introduces an application of these two methods in a TRIZ-based Define–Analyze–Solve–Execute (DASE) roadmap for inventive problem solving. The roadmap provides problem solvers an algorithmic roadmap with systematic methods and convenient tools for analysis and ideation. Especially, with FA+ and CECA+, the solver can identify comprehensive solving directions ‘semi-automatically’, which helps the solver to generate rich ideas along diverse solving directions. As an example, these methods are applied to a project of inventing a self-watering flowerpot.
