How long is a business case?

A good business should be long enough that it contains all the information needed for the decision-makers to take an informed decision about whether to invest in the project. That means, remove any waffle, and only include information which helps decision-making.

  • What’s included in a business case?
  • The following are the most important items to put into a business case:
  • Executive summary – summarizes the key points;
  • The reasons for the project (answers the question ‘Why are we doing this?’);
  • The options considered – e.g. do nothing, do something, or do something else – (answers the question ‘What’s the best option?’);
  • The expected benefits – in measurable terms – (answers the question ‘What’s the return?’);
  • Costs – both project and operational – (answers the question ‘How much will it cost?’);
  • Timescales – for the project and for realizing benefits – (answers the question ‘How long will it take?’);

Investment appraisal – weigh up costs, times, risks against benefits – (answers the question ‘Is it worth it?’);

Major risks – (answers the question ‘What if?’).
