Ten days. One clear picture. A plan you own.

The Performance Diagnostic is the first stage of our method packaged as a fixed-scope engagement. Over ten days we review how your business actually runs, show you where the fastest and most durable gains sit, and hand you a prioritised plan. The work runs at your pace and around your calendar, with no interruption to the business. Whether you then run the plan yourself or with us is entirely your call.

Who it is for

Owners and leaders of businesses, typically with five to fifty people, who sense the business could run better but want evidence before they act. We work across industries, with particular depth in professional and regulated sectors.

No interruption to your business.

Interviews, data requests and the readout are scheduled around your calendar, not ours. Most of the ten days is our work, not yours. If you need it to run slower, it can.

Fixed fee: From $4,500 + GST. The fee is confirmed before we start and does not change. If you go on to a delivery engagement with us within 60 days, the full Diagnostic fee is credited against it. And if the diagnostic call shows the Diagnostic is not the right next step for you, we will say so.

Three steps, each one optional.

  1. Take the free Health Check

    Free. Two minutes, twelve questions, no sign-up. You get a score across six areas and the two places to look first. It is the same lens we use in the full Diagnostic.

  2. Book a diagnostic call

    Free. Thirty minutes with one of our leaders on the phone or Microsoft Teams. Bring your results, or just the problem. We will tell you plainly whether the Diagnostic is worth your money.

  3. Run the Performance Diagnostic

    From $4,500 + GST. Ten days of structured work with your numbers, systems, processes and people, scheduled at your pace, finishing with a readout and a written plan you keep whether or not you continue with us.

What the Diagnostic includes

  • Leadership and team interviews

    Structured conversations with the people who run the business and the people who do the work, so the picture is real rather than reported.

  • Numbers review

    Profitability by client, service or product, pipeline and conversion, capacity and utilisation, and the unit economics of growth.

  • Systems and process walkthrough

    How work actually moves through the business: the tools, the handoffs, the workarounds and the places time and margin leak.

  • Marketing and positioning read

    How clearly the business says what it does, whether the market hears it, and how consistently new work arrives.

  • AI and automation scan

    Where repetitive work could be automated safely, where AI adds real value, and where it does not belong.

  • Opportunity map and 90-day plan

    Every finding prioritised, sized and sequenced, with owners and measures, in a written report and a readout session with the three leaders.

What you walk away with

  • A scored view of the business across finance, sales, operations, marketing, systems and AI
  • The three to five opportunities that matter most, each with the expected gain and the effort to get it
  • A 90-day plan with owners, sequence and success measures
  • A written report and readout that you own outright
  • A clear recommendation on whether further help is worth it, and from whom

What to expect, and what not to.

Consulting has a reputation for long reports, vague promises and a quiet dependency that never ends. The Diagnostic is built to be the opposite.

You will get

  • Senior people doing the work, not a junior team behind a senior pitch
  • Work scheduled at your pace, around your calendar, with no interruption to the business
  • A fixed scope and a fixed fee, confirmed before we start and credited against any delivery work that follows
  • Findings grounded in your numbers, not in a template
  • A plan written so your team can run it without us
  • A straight answer if we are not the right fit

You will not get

  • A 90-page report that no one reads
  • A pitch for a product, a platform or a licence
  • Advice about financial products. We do not hold an AFSL and never will pretend to
  • A plan that only works if you keep paying us
  • Growth targets that ignore your compliance obligations

What sets the work apart.

  • Three leaders, three disciplines

    Most boutiques bring one lens. Every engagement here draws on a systems leader, a brand and communication leader and an education leader, so the plan covers how the business runs, how it is heard and how its people keep the gains.

  • Built for regulated businesses

    Our clients carry real obligations. We design around them from the start, and because we do not hold an AFSL and do not sell financial products, our recommendations about your business are not tied to anything we are trying to sell you.

  • Tools before talk

    Our free tools, articles and published method let you test our thinking before you pay for it. The Health Check on this site uses the same lens as the full Diagnostic.

  • AI that is practical, not theatrical

    We build with AI every week and publish what we learn. We will show you where it saves real time and tell you plainly where it does not belong.

  • Engagements built to end

    Fixed scopes, clear endpoints and a documented handover. We measure success by how little you need us afterwards.

  • Melbourne-based, delivering globally

    We have worked with companies across Australia, Asia, the Middle East and North America. If we are the right fit, distance is not the obstacle.

Common questions

How much of my time does it take?

Plan on four to six hours across the ten days: a kick-off, interviews, a short data request and the readout. We do the rest, and we schedule everything around your calendar so the business keeps running as normal.

What do you need from us?

Access to your management numbers, a walkthrough of your main systems, and time with the people you nominate. Everything is covered by a confidentiality agreement.

What happens after the readout?

You have the plan and you own it. Some clients run it themselves. Some ask us to scope the delivery of specific parts, in which case the full Diagnostic fee is credited against that work if it starts within 60 days. Either is a good outcome.

We are not in Melbourne. Does that matter?

No. We have worked with businesses across Australia, Asia, the Middle East and North America. Interviews and readouts run well over Microsoft Teams.

Is this financial advice?

No. GBX Professional Services does not hold an Australian Financial Services Licence and does not provide financial product advice. The Diagnostic is about how your business operates, sells and grows.
