When to update OSTs

Update your opportunity solution tree when the overall goals are still relevant, but new data or insights come in. A good rule of thumb is to update your OST after every 3-4 customer interviews, as new feedback may reveal opportunities or adjustments.

Also, update when you’ve solved some opportunities and need to shift focus to others. If feedback or research changes your understanding of a problem slightly, adjust the tree without starting from scratch. Regular updates keep the OST flexible and ensure your team is addressing the most current and important needs.
