Objectives and Principles are notions.

Plans consist of actions.

I often ask my colleagues, "do you have a notion or do you have a plan?"

A plan includes enough tactical detail to make it fully actionable.

The misused word "Strategy".

Is a strategy a notion or is it a plan?

Answer: it is ambiguous, which is why I prefer to use Strategic Objectives and Strategic Plans to demystify which we are describing.
