Abstract:To help find root causes to occurring product problems in the industry researchers have made a variety of cause finding tools. An example of this is the Root Conflict Analysis (RCA+), which is part of TRIZ (Theory of Inventive Problem Solving) - a Russian method made by Altschuller. The current RCA+ results show that there is still room for improvement. By interviewing various experts, investigating literature, and brainstorming with students, flaws in the RCA+ method were identified. Templates were made to help gathering and structuring the information beforehand. Besides this, additional rules were formulated to prevent users from stopping with an analysis too soon. This should help in adding more detail to the analysis itself. Results, based on different tests, show that the quality of the RCA+ improves when a template and additional rules are used. The quality improvement is mainly visible in the amount of information considered in the RCA+; both regarding the variety of information and the details considered for all information. From the test results, the conclusion is drawn that the results of an RCA+ can be improved by doing prior research into the problem. This research should include an analysis of the stakeholders, scenario and product.
