ABSTRACT
This chapter considers the measures of evaluation. The ideality of each proposed solution is evaluated and compared with the ideality of other solutions. The assessments are made by way of a simple and practical method, a pairwise comparison with other known solutions. In real-life projects, the standard should be the best possible existing or developing competing methods or technologies. Using the criteria of theory of inventive problem solving (TRIZ) decreases the subjectivity of the evaluation, although it does not remove it totally. To evaluate any solution, first establish the evaluation criteria and then make the evaluation. The criteria should be, as much as possible, independent of the subjective feelings and interpretations of people. Different people should get approximately the same conclusions using the criteria. Repeating the cycle of application of the concepts of contradiction, resources, and improved ideality makes big improvements in the solution and helps overcome psychological inertia.
