Bob Martin's heuristics

These are a different kind of heuristic from those of Arthur Riel 1996. They guide the designer's thinking rather than the design itself.

• Whenever you see the number 1, consider that it might be N.
• Whenever you see a constant, consider it might be a variable.
• Whenever you see two or more concepts that are arbitrarily connected, consider they might need separation.
• If a decision seem arbitrary, consider how it could be made differently.
• Consider that what is ancillary today will be primary tomorrow.
• Consider that what is low volume today will be high volume tomorrow.
