Business Case

Developing your business case

The business case is the document that outlines the justification for the project. It:

  • describes the case for change
  • explains how to achieve best public value
  • considers commercial viability
  • recommends a preferred option, which is affordable and achievable
  • may include options for the exit strategy to be applied at the end of the contract term.

For an introduction to writing Better Business Cases, visit the Treasury website. The Treasury also provides guidance and templates for writing business cases depending on the decision being sought, the nature of programme or project and the associated scale, risk and uncertainty.

Review of significant procurement plans

Under the Government rules of sourcing (Rule 19),  MBIE undertakes reviews of procurements that meet one or more of the Significant Procurement Plan (SPP) criteria, which are procurements that:

  • have an estimated total value over the whole-of-life of the contract of NZ$5 million or more
  • due to the nature or complexity of the procurement, it would expose the agency or government to significant risks if it were not delivered to specification, within budget and on time
  • have the potential for cross-government collaboration or resource sharing.

MBIE’s review focuses on any planning document that details how an agency has researched and analysed the market and describes the intended approach to market, including the evaluation criteria and methodology. The planning document may be a business case, but will more often be a procurement plan, a sourcing plan or similar. MBIE aims to provide a supportive peer review to help agencies achieve the best outcome from their procurement.

SPPs are submitted to MBIE in confidence and are not published, however MBIE may forward documentation received to other Functional Lead agencies if they relate to ICT or office-related Property procurement initiatives.
