One question
The shift to value-driven thinking from the old feature-driven thinking can be a hard one. It can take some time.
But one thing you can start now is simply to ask yourself a question anytime you get a new idea for a feature:
What's the actual business value that I will get from this improvement?
The answer should have a number and a unit. It could be hours of staff time saved, or a percentage of membership sign-ups increased, or even a percentage of how much easier your life would be.
You don't have to change everything at once, but just asking yourself to put a number on things can give a whole new perspective to your work.
All the best,
A.
