The algorithm is completed with the testing stage. It is necessary to understand whether the issue has changed and whether these changes are positive enough.
During the testing stage, the final solution should be transformed into a specific technical proposal and it should be found out whether the conflict is resolved and the problem is remedied.
This testing can be done either at the end of solving the problem or, optionally, at any of its steps.
Step 3.1. Prepare a technical proposal
Input: the final solution.
Action: describe the system transformed in technical terms.
Output: a technical proposal
Based on the final solution, the technical proposal, i.e. a detailed description of the system transformed and involved in the situation, is formulated.
When preparing the description, mental or real-world experiments, an expert assessment is carried out. To do this, a number of methods exist: the DOE (design of experiment), the Taguchi method, the multifactor experiment planning, computer modelling, etc.
Step 3.2. Assess the system conflict resolution
Input: the technical proposal.
Action: assess whether the solution offered resolves the system conflict.
- system conflict resolved > proceed to the issue addressed;
- system conflict unresolved > proceed to step 1.3 (develop conflict resolution hypotheses and state the problems).
At this step, we should check whether the system change offered actually removes the interaction among the components which does not satisfy us. Engineering experience and an expert assessment can be of use in this case.
Then we check whether the issue has been addressed. The actions at this step and at step 1.2 are similar to a great extent.
It is required to develop the desired model of the issue addressed in accordance with the laws of development of technical systems and to assess the degree of approximation of the real-world situation to the desired one.
If the degree of approximation is high enough, then the conflict can be deemed resolved, we have the issue addressed which satisfies us. The project is completed successfully.
If the situation changed does not correspond to the desired one, the conflict is not resolved. Lack of the positive result can have four reasons:
- we have selected the key problem incorrectly;
- we have not solved it good enough;
- we made a mistake when formulating the problem from the hypothesis;
- the hypothesis of how to resolve the conflict is not true.
It is necessary to select the problem formulated on the basis of another hypothesis or to develop new hypotheses of the conflict resolution and to repeat the complete cycle.
