The NZ Transport Agency’s Business Case Approach (BCA) is a robust, principles-based approach for developing business cases for investment through the National Land Transport Programme (NLTP). It is based on the New Zealand Treasury’s Better Business Cases.
Applying key BCA principles and behaviours helps to ensure that business cases are developed in a fit-for-purpose way that provides value for money. That is, doing the right thing in the right way, at the right time and place, and for the right cost.
The BCA supports planning and investing for outcomes, ensuring early collaboration between stakeholders and progressive development of a robust, evidence-based investment case. It helps business case writers develop a robust proposal for investment by:
The BCA breaks down the work that needs to be done for a robust business case into phases, which means the case can be built up progressively, and decisions about whether or not to proceed can be made at regular checkpoints.
Rather than being a process to be followed from point A to B to C, the BCA phases are a way of grouping the critical thinking that needs to happen and the decisions that need to be made to progress the business case. Depending on the complexity of the problem/investment, you may not need to go through all phases, or you may be able to group them together. However you approach the business case, you will need to answer the same questions and fulfil the same requirements.
The phases are:
If the proposed investment is very high risk and complexity, you may choose to do a separate IBC before beginning a DBC.
This guidance is primarily for organisations in the transport sector who are seeking investment from the National Land Transport Fund (NLTF) through the National Land Transport Programme (NLTP), such as councils, territorial authorities and the Transport Agency itself. It is also for consultants who may be involved in developing business cases for their transport sector clients.
The BCA should also be followed by organisations preparing activity management plans (AMPs) and regional land transport plans (RLTPs).
Underpinning the BCA are the following principles.
Investments are made to obtain organisational benefits. An investment should: contribute to the organisation’s strategic outcomes, represent value for money, and deliver benefits for customers.
The intention driving an investment must be clear. Simple concepts and plain language will provide a clear understanding of the problems and benefits.
The level of effort required to develop a business case must be proportionate to the complexity and risk of the problem and the proposed investment.
These behaviours ensure the principles are applied correctly.
Successful investment management relies on gathering knowledge through informed discussion between the people who have the most knowledge of a subject.
The BCA relies on a structured, sequential approach to decision making, checking each phase as you go. All investments must follow the same line of enquiry.
These capabilities are essential to a successful BCA process.
Identifying a potential problem’s origin and exploring what work may have already been done will help you to better understand it and to define the likely benefits of investment.
Gathering information through informed discussions with stakeholders is a key BCA behaviour. Effective stakeholder engagement also helps promote innovation and collaboration among stakeholders.
Making sure everything is aligned and set up correctly enables efficient and effective use of resources and minimises risks.
The Transport Agency assesses the proposed investments at the end of the strategic case, programme business case and single-stage business case phases (or after both the indicative and detailed business case, if you are doing them separately). It uses the 16 business case assessment questions and the Investment Assessment Framework (IAF). This is called an investment decision gate, and ensures that the investment will be cost-effective and aligned to the strategic priorities of the government as outlined in the Government Policy Statement on Land Transport (GPS). Based on the outcome of the assessment, the problem owner and investor(s) decide whether or not it is worthwhile continuing with the business case.
