ITRIZ is currently used for solving technological problems. I´ve used it solve management problems, since management is a "technology" used to manage social systems it has worked well. The metodology uses a database extracted from the way pattents have been used to solve other "systemic problems" and one uses these "sistemic solutions" analogicaly to solve your own problems. Certainly the database would be more usefull if the examples would be of a business nature, which certainly can be done. The methodology has several core concepts that apply perfectly to the business world. The main benefit of the methodology woulb be to have a clear understanding of complex sistemic problemas and that you can produce up to 90% of the solutions available for the problem. Having such a near exhaustive number of solutions guarantees statistically that the best solutions has been found.
The biggest value generating solutions are found in typical trade off situations. ITRIZ works best when trying to takle these types of problems.
