📋The task

© Alexander Sychev, Sergei Sychev, “TRIZ-RI Group”

One of our projects contains the following tests for hiring programmers:

"There are three groups of organisations (legal entities):

  • Our companies,

  • A certain number of companies of the Client,

  • A few companies of our suppliers.

Sometimes the same companies can be in different groups simultaneously (ie, sometimes some of our Customers can be our suppliers). There are people who:

  1. Work in the above-mentioned companies:

  • in our companies,

  • in the companies of our Clients,

  • in the companies of our suppliers,

  1. Do not belong to any company - individuals who buy our products.

Build a database structure".

Let us consider three levels of answers: weak, medium, and ideal (which we will try to build using TRIZ).
