After selecting a way to measure model complexity users should define limits to what they consider reasonable limits. Consider using different limits for junior vs senior modelers.

Recommendation: Limit main complexity measures per Creator project as follows:

  • Do not exceed and try to cover more than a maximum of 100 testable requirement references

  • Do not exceed a maximum of 100 tests to cover model logic, i.e., not counting tests whose only difference or value is to cover combinatorial or spreadsheet data

  • Do not exceed 20 activity diagrams project and do not nest them deeper than 5 levels.

  • Less than 20% of all activity diagrams should be of high diagram complexity.

  • Keep diagram complexity in line with your knowledge level

Note that the limits of 100 requirements and 100 tests are not coincidental – we should target to have at least one test per requirement. In other words we can use the number of tests as a basis to reason about requirements even if they are not explicitly referenced in a model. If you want to increase the number of tests per requirement, then rather reduce the maximum number of requirements than increasing the maximum number of tests.
