Why your business plan is probably too long

There is a persistent belief that a serious business needs a serious business plan — bound, formatted, with financial projections stretching five years into the future. The reality is that most business plans are written once, presented once, and never opened again.

The problem with long plans

Length creates a false sense of rigour. A 40-page document can mask weak thinking just as easily as it can demonstrate strong thinking. The difference is not in the page count — it is in the clarity of the assumptions and the specificity of the actions.

If your plan cannot be summarised in a single page, the strategy may not be clear enough to execute. That does not mean detail is unnecessary. It means the detail should serve the strategy, not substitute for one.

What a useful plan looks like

The most effective business plans we see in practice share a few characteristics: they fit on one to three pages, they state the objective in a single sentence, they identify the three or four things that must go right, and they include a 90-day action list with named owners.

Financial projections are included — but as a range, not a single line of false precision. And the plan is reviewed monthly, not annually.

Plans should be living documents

A plan that sits in a drawer is not a plan. It is a historical record of what you thought you would do. The businesses that execute well are the ones that treat planning as a continuous process — short cycles, regular reviews, honest assessments of what is and is not working.
