Every successful project starts with a decision.

Should we invest? Is the project achievable? Will it deliver value? What are the risks?

Before organisations commit time, money and resources to a project, they need confidence that the investment is justified. That’s where a well-developed business case becomes essential.

For organisations across New Zealand, developing clear, evidence-based business cases helps improve decision-making, secure stakeholder support and increase the likelihood of successful project delivery.

In this guide, we’ll explore what Better Business Cases are, why they’re important and how developing these skills can benefit both individuals and organisations.

What are Better Business Cases?

A business case provides the evidence needed to justify investment in a project, programme or initiative.

Rather than simply explaining what an organisation wants to achieve, a good business case demonstrates:

• Why the investment is needed
• The expected benefits
• The available options
• The potential risks
• Estimated costs
• How value for money will be achieved

The Better Business Cases™ methodology provides a structured framework for developing these business cases, helping organisations make informed, transparent investment decisions.

It is based on the internationally recognised Five Case Model, originally developed by HM Treasury and widely adopted across the public sector and many large organisations.

Why are Better Business Cases important?

Projects often fail long before work actually begins.

Poor planning, unclear objectives and weak investment decisions can all lead to delays, increased costs and benefits that are never fully realised.

Developing a robust business case helps organisations:

• Make better investment decisions
• Demonstrate value for money
• Compare different delivery options
• Gain stakeholder confidence
• Reduce project risk
• Improve governance
• Increase accountability

Ultimately, Better Business Cases help organisations ensure they are investing in the right projects for the right reasons.

Understanding the Five Case Model

The Better Business Cases methodology is built around five key questions.

Strategic Case

Why is the project needed?

This case explains the organisational need, strategic objectives and the problems or opportunities the project aims to address.

Economic Case

Which option delivers the greatest overall value?

Different options are assessed to determine which provides the best balance between costs, benefits and risks.

Commercial Case

Is the proposed solution commercially viable?

This considers procurement, suppliers, contracts and commercial arrangements.

Financial Case

Can the organisation afford the investment?

The financial case looks at affordability, funding arrangements and ongoing financial implications.

Management Case

How will the project be delivered successfully?

This covers governance, project management, risk management, reporting and assurance arrangements.

Together, these five areas provide decision-makers with a comprehensive picture before investment decisions are made.
