Better Business Cases - Investing for Change for Better Value

Page updated 22 Aug 2014


The primary objective of Better Business Cases (BBC) is to improve decision making through fit for purpose business cases.

The secondary objectives are to:

  • reduce the costs of developing business cases
  • make the business case production and review process more efficient
  • conform with recognised good practice.

What is Better Business Cases (BBC)?

BBC is a systematic way that stakeholders can work and think together to provide a business case, with fit for purpose analysis, which gives confidence to decision makers that investing in a proposed programme or project is justified following the five case model:

there is a compelling case for change, 'Strategic case'; the way forward optimises value for money, 'Economic case';
									 the potential deal with the market is commercially viable, 'Commercial case'; the proposal is affordable, 'Financial case';
                                     the proposal can be delivered successfully, 'Management case'

If, after the investment decision, the project is well delivered and/or the programme is well managed there is greater likelihood that project benefits will be delivered and/or programme outcomes will be achieved.


The New Zealand 'concise' version of the guidance is based on the UK version, with the consent of the International BBC Steering Committee (HM Treasury, the Welsh Government, and the New Zealand Treasury). The International version is to be released late 2014.


We provide downloadable guidance products for specific type of business cases whether they are for proposed programmes or projects.

Priority Public Sector Organisations can nominate potential experts. Each candidate seeking endorsement needs to submit their application form, with two business cases and a 360 survey by 19 December 2014 for interview and assessment by the International BBC Standards Board (scheduled in February 2015).
