Abstract
In this paper we propose a creative method to support ARIZ, a step-by-step method for problem solving invented by Altshuller in 1956. Specifically, we propose a new formulation of step zero, which deals with clarifying and verifying the problem statement. Since the birth of ARIZ, step zero has been continuously updated; ARIZ-56, ARIZ-59, ARIZ-61, ARIZ-64, ARIZ-65, ARIZ-68, ARIZ-71,ARIZ-75, ARIZ-77, ARIZ-82, and 3 versions of ARIZ-85 prove all attempts to balance convergent and divergent phases in order to change the perspective on the given problem, adding useful information from the market or the patents, igniting lateral thinking and overcoming psychological inertia. After Altshuller's death, ARIZ development has been continued by TRIZ masters and followers without establishing a reference model.This paper proposes a revision of two classical Altshuller's tools, the “multiscreen method” and “76 standard solutions” to be used in the problem formulation phase. The first one is called Film MakerTM and is a simple tool to manage the cause-effect relationship through the description of a film, i.e. a sequence of events. The second one is called “111 Standards” and is a structured elaboration of Altshuller's 76 standard solutions to systematically identify alternative partial solutions. A four step method containing these tools is presented together with an exemplary case.After more than 2 years experimentation within a project commissioned by the chamber of commerce of Bergamo, involving over than 30 companies, we discuss the results and efficacy of this approach
