The article presents the further development of the report presented on SECR-2009. It was written specially for SECR-20171. In contradistinction to the previous report the current article gives the review of TRIZ application experience, as well as an algorithm of analysis and development of project ideas in the area of IT. An electronic template of demand contradictions formulating is also described. A brief review of proceedings about TRIZ methods application for efficiency improvement of all software development life cycle stages is given in the article. Starting from1985 TRIZ community works on transfer of TRIZ instruments from tangible technical systems to intangible ones. This process demanded a serious review of important TRIZ concepts such as product-instrument, substance-field etc. Foundation stone of TRIZ - the concept and wording of a contradiction - also requires a review. TRIZ application in an area of IT is one of the most perspective directions of TRIZ development in intangible systems. Some methods, that have already proven to be the effective tools for software development process, are given in the article. The algorithm of analysis and development of project ideas in the area of IT and software is given. Electronic template for simplification and improvement of accuracy of wordings of contradictions of demands and their solutions in software development is worked out. There are illustrations of some TRIZ instruments application for software development. The article will be useful for software developers, analysts, decision-makers in the development of new solutions in the field of IT.
