The startup scoreboard is the summary of your startup scores. There is no “right” score, it is always up to you when you think you are ready to start your new business.
Planning and research are both drivers that can be improved, just by effort, therefore I think that any person starting a new business should work hard enough to get their planning and research scores at 50% or better. Knowledge and experience is a little harder to obtain and will probably take longer to get, these drivers should be somewhere above 40%, possibly 50% to start with. Risk and complexity really shouldn’t be above 60% I think, as that type of level puts the startup into a “much more likely” to fail state. High risk and high complexity usually equate to high costs and lengthy delays.
The overall success score should ideally be over 50% but how far over is up to you, but I would be aiming for somewhere around 70%.
Remember though, everything is relative. If your startup has the potential for high returns, then you may be prepared to accept high risks and high complexity.
It’s all up to you to decide.
