The board has approved funding. The case is sound, the timing is right, and the firm with the strongest credentials has been shortlisted. The next decision is straight forward, and here’s where the cost compounds. The chosen firm is also the one who will define what the program is. Unfortunately, whether the program addresses the right problem is the same party who stands to gain from delivering the solution. You didn’t buy a path out of the core issue. You bought a fait accompli.
In Brief
- An independent diagnostic assessment is a governance instrument the executive initiates before the next phase is approved, separate from the firm that will deliver it.
- Australian executive buyers are paying for standalone diagnostics because the major firms still bundle assessment inside their delivery pitch.
- ANAO performance audits show that procurement processes which collapse assessment and delivery into one engagement consistently fail to demonstrate value for money.
- The diagnostic that runs before scope is set produces a different decision than the one that runs after the contract is signed.
This is not unusual. It’s the standard sequence. And this sequence is what senior buyers in Australia are now beginning to interrupt.
A market the firms missed
The Australian management consulting services market is on track to reach USD 12.66 billion by 2031, growing at 6.07% annually, with the government and public sector segment holding the largest share of demand at 18.24% (Mordor Intelligence, 2026). Independent forecasts from IMARC Group put the management consulting segment at USD 5.6 billion in 2024, rising to USD 10.4 billion by 2033 at a 6.7% compound rate (IMARC Group, 2026). Demand is rising and executives are now starting to discriminate between diagnosis and solution.
Major firms, however, still package assessment as the opening phase of a larger program because their commercial model rewards continuity. They often do not sell a defined, fixed-fee independent diagnostic assessment as a standalone consulting service. This gap is what executives are walking into.
What the audit office keeps finding
The Australian National Audit Office has examined this pattern across multiple performance audits of Commonwealth procurement. In its review of Moorebank Intermodal Company, the ANAO found that open and effective competition had not been a feature of the company’s procurement of consultants, and that probity risks, including conflicts of interest, had not been well managed. Senior managers had sourced consultants who were long-standing business or personal associates. The relationships were not hidden, but they were not formally disclosed either, and the related probity issues were not addressed (ANAO, 2018). The pattern is not isolated to one entity. ANAO’s analysis of its 2024-25 audit program found that 55% of grants administration audits returned negative conclusions, with grants and procurement carrying the highest share of adverse findings across the entire portfolio at 23% and 19% respectively (ANAO, 2025).
The lesson the ANAO keeps highlighting is not that procurement officers are negligent. THeir processes all too often collapse several very different decisions into one transaction:
- What is the real problem to solve?
- What should the work be? What method. What solution?
- Who should do it?
These decisions are being made by the same party at the same moment. The result is predictable. Value for money cannot be demonstrated because value for money requires that the question to be answered by someone with no stake in the answer.
Be careful about what you are actually buying
A standalone independent diagnostic assessment is not a sales process. It is not a free workshop, a credentials pitch, a discovery call, or any of the other forms in which the major firms hand the assessment back to the buyer as part of a longer commercial conversation. It is a defined-scope, defined-fee engagement that produces a written assessment of the executive’s actual situation. That means defining the real problem, identifying the actual constraints, and highlighting the questions any subsequent program downstream must answer. The deliverable is the assessment itself. The next decision sits with the executive, not with phase 2 of the same firm.
This is what the ZXM Diagnostic Engagement is structured to deliver. It is a single named product the executive initiates, scoped before any program work is approved, with no presumption that ZXM will be selected to deliver whatever follows.
The reframe that matters here is governance, not procurement. An independent diagnostic assessment is the same instrument the board uses when it requests an internal audit before approving a major capital decision, or when it engages an external probity advisor to oversee a procurement. The executive who initiates a separate diagnostic is doing what the board would expect of them on any other decision of comparable consequence. They are establishing that the question has been answered by a party with no commercial interest in the answer before they authorise the spend.
Harder than it looks
The reason most executives do not separate the diagnostic from the delivery is not that they have failed to think it through. It is that the major firms have not made it easy to buy assessment by itself, and the procurement instruments most agencies and corporates use are built around delivery contracts, not advisory ones. The path of least resistance is to fold the assessment into the delivery proposal, accept the firm’s framing of the problem, and approve the engagement.
What changes when the diagnostic is initiated separately is that the executive enters the next decision with their own picture of the situation, not the delivery firm’s picture. Scope conversations become shorter. Vendor proposals become easier to read against a known reference point. The risk that the firm with the strongest pitch is not the firm best suited to the actual problem is materially reduced.
What this asks of the executive is small in commercial terms and large in governance terms. An independent diagnostic assessment costs a fraction of the program it informs. The discipline it requires is the willingness to spend time and a small budget answering a question the executive could otherwise leave the delivery firm to answer for them. Executives who are already navigating boards, ministers, or audit committees recognise the move immediately. It is the same posture they would take on any other decision where independence of analysis matters more than speed of execution.
Executives who are paying for diagnostics as a standalone product are not buying a methodology. They are buying the insights to support their next decisions, before a solution firm has had a chance to define what the work is.
