Advanced Systematic Inventive Thinking (ASIT) is an inventive problem solving method developed by SIT in the 1990s by Roni Horowitz, a pupil of Altshuller. 

ASIT proposes a methodology for systematic approach to creative solutions where participants are led to think around compound sentences with the elements of the problem. 

In the principle of SIT’s “closed worl”, ASIT proposes to add a new rule of creativity: we must look for solutions in which the influence of the main factor of the problem is either eliminated altogether, even reversed.

Step 1 : Preparation

First, list the elements that make up the problem or its immediate environment. Then reformulate the problem from the point of view of its solution by defining the objective to reach. 

Step 2  : Analysis of the problem

As a group, we will apply each of the 5 tools of ASIT to reformulate with each of them the problem and see the solution.

  • Unification : uses already existing objects in a new way, optimizes existing ones.
  • Multiplication : use objects of the same type as the objects present or add new elements with a constraint not to get away from the problem.
  • Dividing : reorganizing existing objects and processes. 
  • Breaking symmetry : removing the circumstances of time, space, group.
  • Deleting : remove one or more objects.

Step 3  Sorting & Selection

Last phase, we will sort and select the most interesting concept (s) according to the market. 

An example

Police security barriers are easily reversed when there are many people pushing them. When people are asked to solve this problem, they usually propose solutions that prevent protesters from reaching the barrier or attempt to secure the ground barrier. This bad reflex does not give good results and they are not innovative (because everyone proposes them).

By following the ASIT process:

  1. We reformulate the problem by: “The more protesters are around the fence, the less stable it is. “. This tells us then to look for a solution giving the following result: “The more people close to the barrier, the more stable it is. So, imagine a barrier that stabilizes when there are people nearby? 
  2. Using the “multiplication” tool, a concept comes out. Indeed, it would be enough to have a second ground barrier, fixed at the first, on which the protesters rest. The more there is, the more the barrier is stable.
