A business plan is not a user manual. It’s not a map of a defined territory and it’s not a even a vision of the future. At best it is a contention of how we may be able to get things done. Because of this, we need realise it can and should be revised as soon as it is unproven. Yes, we should give it a chance, execute against the contention, but remember it is only as valuable as the results it generates. We can throw it away, draft a new one if needed.
While important, a plan must serve us. We ought not serve it.
