The 2 main types of decisions for ceo/head/founder
There are 2 main types of decisions that you can take as a productmanager/Head/CEO/founder
#1 The decision taken is impossible to turn back
These decisions are called "one-way door" which means that they would be extremely difficult/long/expensive/not proportional to the potential benefit and usually impossible to reverse.
For example: selling a company, a vague contract, or dismissal from work. Once you accept and implement such a decision, there will be no way back.
That is why it is necessary to spend as much time as you think necessary on such decisions and never rush with such a decision.
#2 The taken decision can be rolled back
Such decisions are called "two-way doors" and they can always be rolled back and replayed.
For example: a bold product hypothesis or feature, concept or strategy adjustment, launching a new sub-product, a new advertising channel, etc.
With "two-way doors" there is no need to be afraid to take such decisions (even if there is insufficient data for them). For if something goes wrong, they can be... quickly rolled back as well.
