Business Case Development

We develop business cases for government programs and investments, providing a clear, evidence-based case for funding and policy decisions. Our work combines rigorous economic analysis with a strong commercial focus, ensuring proposals are robust, credible and able to inform decisions.

What is a Business Case?

A business case is a structured, evidence-based assessment of an investment proposal. It defines the case for change, evaluates alternative options, and demonstrates value for money, financial feasibility and deliverability.

Why is a Well-Developed Business Case Important?

A well-developed business case demonstrates that an initiative is justified, delivers value for money, and is financially and commercially viable. It supports transparent decision-making, helps secure funding and approval, and provides a sound basis for implementation.

Our Approach

We follow a structured approach, working through each stage of the business case development process:

• Establishing the Case for Change (Go/No-Go)
  We confirm the need for change, assess strategic alignment, and identify expected benefits, providing a clear basis for deciding whether to proceed.

• Identifying and Analyzing Options (Preliminary Business Case)
  We explore a comprehensive range of options and assess them using cost-benefit analysis and financial appraisal, producing a refined shortlist of viable options.

• Selecting the Preferred Option and Planning Implementation (Full Business Case)
  We prepare the preferred option for decision and implementation, including detailed cost-benefit and financial analysis, procurement and risk planning, and a benefits realisation framework.

• Proportionate Pathways

  For smaller or lower-risk proposals, we also deliver Lean Business Cases and Short-Form Assessments, ensuring requirements are met without unnecessary complexity.

For government clients, all business cases are developed in line with relevant business case guidelines and consistent with gateway assurance processes.

Our Expertise

Our team brings specialist expertise across all stages of business case development:

• Facilitation and Stakeholder Engagement

  We coordinate stakeholder engagement throughout the business case process, aligning interests and building consensus.

• Cost-Benefit Analysis and Financial Appraisal

  We undertake rigorous economic and financial analysis to assess value for money and financial feasibility.

• Commercial and Management Analysis

  We support procurement strategy, risk management and operational planning, helping establish practical and effective implementation arrangements.

• Benefits Realization and Performance Management

  We set measurable objectives and create monitoring frameworks to track outcomes and support benefits realisation.

Business Case Training and Capability Building

In addition to developing business cases, we provide tailored training and capability-building services in business case development. Our workshops, delivered in-house or publicly, in person or virtually, equip participants with practical skills and knowledge for preparing effective business cases. Recent workshops have included Cost-Benefit Analysis for Business Cases, designed for NSW Government agencies implementing the NSW Government Business Case Guidelines TPG24-29.

Examples of our Business Case Development Work

NSW Government | OneCX program

In 2019, a review identified more than 1,000 NSW Government websites on 35 different content management systems. 

The review highlighted that government could:

• create a better digital experience through consistent design, content and style

• find cost efficiencies by reducing unnecessary duplication of functionality.

As a result, the NSW Government Digital Channels team developed the OneCX program to create a unified and customer-centric digital experience for people in NSW, making it easier for people in NSW to:

• complete specific tasks online in fewer clicks on fewer websites or in less time

• find consistent information through search or by browsing customer-centric topics on one website

• voice their opinion on what the government is doing through a central channel.

As more content is published on nsw.gov.au, there will be fewer websites centred around the structure of government. Instead, digital information, services and transactions are now being organised by customer-centred topics on:

• the nsw.gov.au website for information

• the Service NSW website for services and transactions.

Through 2020, we supported the NSW Government Digital Channels team to develop their detailed business case (including cost-benefit analysis) and to progress through Gateway review processes. This was all done whilst the Digital Channels team were preparing to launch the nsw.gov.au beta site and then delivering a whole of government digital communications response to the COVID-19 pandemic.

As the OneCX Program is progressively rolled out, it’s making it easier for customers to access the information they need, without having to understand or navigate the structure of government. Around 2.74 million people are visiting nsw.gov.au each month and, at the end of 2025, more than 190 websites have been migrated and/or decommissioned.

NSW Environment Protection Authority - Asbestos Coordination, Clean-Up, and Awareness Initiative 

Australia’s widespread use of asbestos during the twentieth century (from 1930s to 1980s), and its history of mining and producing asbestos since the 1900s, has left an asbestos legacy across NSW, in both the built and natural environment, that will need to be managed for many years to prevent asbestos-related disease in the state.

In 2015, there were an estimated 4,152 deaths in Australia due to asbestos-related disease[1]  – more than 3-times the number of fatalities on Australian roads in the same period (2015: 1,209[2]).

NSW Environment Protection Authority led the development of a proposed 4-year initiative to help prevent asbestos-related disease in the state through the improved safe management of legacy asbestos and more comprehensive asbestos education and awareness.

We supported the funding submission through the development and preparation of a business case, including cost-benefit analysis.   The submission was successful with funding commencing in 2018/19.
