It’s a simple statement: all business plans are wrong, but nonetheless vital.

Paradoxical, perhaps, but still very true.

All business plans are wrong because we’re human, we can’t help it, we’re predicting the future, and we’re going to guess wrong.

But they are also vital to running a business because they help us track changes in assumptions and unexpected results in the context of the long-term goals of the company, long-term strategy, accountability, and, well, just about everything the plan-as-you-go business plan stands for.
