As no two products or entrepreneurs are the same, there isn't a set schedule for how fast to go through this program. As time is our scarcest resource, you want to go as fast as possible but no faster than the pace of customer learning.
That said, you'll find a suggested schedule below for a baseline to target against.
I find that most people can get through the problem/solution fit stage in ~8 weeks.
- First 2 weeks are building your business model foundation.
- Next 6 weeks are broken into 2 week iterations for problem/solution fit validation and course correction.
- Goal is to have an evidence based go/no-go decision on your business model by the end of 8 weeks (or less).
