An insights taxonomy should help give us the context we need if we are looking at it in isolation.
If we made a test in Italy, for example, that is important to know if I am in Japan. This could be good evidence that there is something there, but our cultures are different enough to make me want to retest this.
The 'insight type' is also interesting:
A Principle is something that likely effects every part of our organization.
A Strategic insight might be specific to a particular team or feature - but guides our strategic thinking.
A Tactical insight is likely to be very specific to just that part of the experience - such as the position of a button.
I also think it's important to make it clear when an insight is specific to a Prototype.
We might want to add an insight as an Assertion or hypothesis.
And once we’ve moved that button we might want to mark the insight as Obsolete or completed.
