Application of TRIZ Substance-Field Analysis and Situational Analysis for Risk Analysis and Development of Common Language Among Stakeholders

The aim of this research is to explore the application of Substance-Field Analysis and Situational Analysis for system modelling, risk analysis and for development of common language among stakeholders. To establish the abovementioned influence of Substance-Field and Situational Analysis this research considered a product in the sustaining product life-cycle phase. Non-TRIZ tools such as FMEA (Failure Modes and Effects Analysis) are often used for risk analysis when assessing the impact to any changes introduced to the design. Substance-Field Analysis and Situational Analysis were introduced to complement FMEA. The benefits and value of both TRIZ tools added to current approaches were evaluated and explored. The research shows that using both tools can work together and complement existing problem-solving methods applied within an engineering organization. Firstly, Substance-Field Analysis tool was found particularly useful for modelling the system, risk analysis and idea generation and very effective for development of common language among stakeholders (such as project/ program management, director, etc.) Secondly, Situational Analysis was found exceptionally functional for prioritizing and identifying the appropriate level of actions to respond to a problem. It also helped improving communication among stakeholders. There are several limitations of this research. This study was conducted within a single engineering firm. Also, it considered a product only in the sustaining product life-cycle phase. Therefore, the research findings of this study cannot be generalized for all companies and for a complete product life-cycle. Additional investigations are required for further generalization of the findings.
