I work alongside CEOs when leadership is the constraint
Over twenty years in Defence, infrastructure and federated organisations I have most often been dropped into complex, ambiguous situations where the real problem has not yet been identified. Arguably the cause is as likely to sit in leadership and teaming behaviours as it is in structure or process, so I diagnose the whole system first and then lead the recovery.

I work with Defence and Defence industry, infrastructure and major programs, and federated organisations where many entities operate under one brand, most often at the point where the next stage is bigger than the current design.
A CEO needs a leader alongside them to lead their leaders through turnaround, stabilisation or recovery, with authority and without a long handover
A transformation program has lost momentum, stakeholder confidence, or delivery discipline
Investment in technology, AI or a major program is not producing enterprise value, with gains at team level failing to reach the bottom line
New capability has been introduced, but work design, decision rights and accountability were never changed around it
The organisation is growing faster than its structure, governance and people systems were built to handle
Performance has plateaued despite sustained investment in strategy, people and systems
A board or executive is being asked to approve AI or a major capital investment, and it is unclear whether the operating system underneath can absorb it
Recognise several of these together? Six symptoms that program risk has become an issue →
I am Aaron Thomas, principal of Systemic Advisory. My career has been built in high-change environments, in roles where the brief was to fix what was broken, stabilise what was failing, and build the systems that make performance hold afterwards.
Twenty years of Defence service, from enlisted through to commissioned officer, produced a specific capability. I can read an organisation quickly from the delivery layer as well as the executive layer, and understand what a decision costs the person who has to make it work. That pattern recognition has since been applied across a $4B Commonwealth infrastructure portfolio, a 150-entity stakeholder community, and national capability programs reaching 5,500 people.
I work through co-design. The people who carry the work help build what replaces it, so the capability stays in the organisation once the engagement ends.
Twenty years of people leadership and systems thinking, applied across Defence, infrastructure and federated organisations.
Engaged to support a Defence client on an infrastructure program uplift. The engagement framed the system and analysed it in detail to determine the problem and solution state with a supporting roadmap. Engaged to lead alongside the client's senior executive, acting as senior partner to 10 Defence leaders to achieve national outcomes. Acquired client decision-making authorities, attending steering groups as the sole client representative.
Navigated a complex NFP stakeholder community of 150 independent legal entities operating under one brand. Briefed the COO on a weekly basis and held direct engagements with the CIO and technology leaders. Delivered projects on time and at or under budget. Developed a $5M strategic program for board consideration.
Held sponsor-delegated authority to lead a national training and change strategy for a vehicle fleet rollout. Designed the approach, ran initial pilots to prove the concept, and led a rollout that cascaded capability through the enterprise to 5,500 people across geographically dispersed locations.
Most engagements start with a conversation about what is actually happening, and the proposal tends to follow from that. The situations that most commonly bring organisations here: a not-for-profit dealing with leadership and delivery breakdown; a government or infrastructure program that has stalled or lost executive confidence; an organisation undertaking a major restructure, technology uplift, or preparing for the next stage of growth; a CEO who needs someone alongside them to lead through turnaround without a long handover.
When leadership is the constraint, I work alongside the CEO and lead their leaders directly, holding executive accountability with full delegated authority where the situation needs it. Two decades of leading teams of teams in high-stakes environments, with the presence to take hold from day one and no lengthy run-up.
For organisations in structural instability, and for programs that have stalled, gone at risk, or lost executive confidence — including government programs, infrastructure programs, and federated organisations where delivery discipline has broken down. The first task is to read the system rather than impose a solution, then find the systemic causes underneath the surface delays, rebuild governance, and restore assurance without losing the people who have to deliver.
For organisations undertaking a major restructure, integrating capabilities during a technology change, or growing faster than their current operating model was built to handle. Growth, restructure, technology change and strategic uplift share a failure pattern: the operating model was built for the stage before this one, and the delivery program runs as a separate system from business as usual. This engagement diagnoses the current state across the eight capability domains and redesigns the model for what the organisation is becoming.
Boards and audit or risk committees are increasingly asked to approve AI, major capital and operating model change, often before anyone has tested whether the organisation can carry it. I advise directors and executive teams on transformation governance and accountability structures, either as a one-off independent review or on a monthly retainer, so the board can ask sharper questions of management and have some confidence in the answers.
One way to start is the Enterprise System Health Check, a two-day on-site screening that shows where the organisation is actually constrained, across eight connected capability domains: technology, governance, structure, people, process, information flow, data, and purpose.
Day one is one-to-one sessions with each functional executive. Day two triangulates what was said against documents, systems and the people doing the work. You receive an enterprise traffic-light view and an executive summary of systemic findings.
The Health Check tells you where to look. The Enterprise System Diagnostic establishes what is true, what is constraining performance, and what has to change first. Where the Health Check findings warrant it, the Diagnostic can follow, and it can also be commissioned on its own, depending on what the situation needs.
Scope and fee are agreed with you at the outset, based on the organisation and what it is trying to resolve.
A reading of Australia's 2026 executive priorities, and the systems engineering principles that make it steerable. Why the current executive agenda demands a system view.
Organisations pursuing AI integration one workflow at a time are accumulating a hidden constraint. The symptoms appear later, and by then they are significantly more expensive to address than the original problem.
As professionals do progressively less foundational work and move into AI oversight, the capability to validate AI outputs, and to operate without it, may be quietly eroding.
Most programs in recovery showed the same handful of signs for months beforehand. Six symptoms mapped to the eight capability domains, and how a baseline helps a program manage its way back.
The operating model describes how an organisation intends to work. The operating system is how it actually runs, and the difference decides whether strategy converts.
A test an executive can run in an afternoon on five recent decisions, and how to read where the line from strategic intent breaks.
Most costly surprises in a restructure or system change occur at the boundary between two domains. A short pass to find them before approval.
Acting first and understanding first both have a case. A way of sequencing the two that favours moves which can be reversed.
The questions asked at approval largely decide what a board can see afterwards. Five of them, and what to listen for in the answers.
If any of this is close to what you are dealing with, I am happy to have a conversation about it.
A focused conversation about what you are navigating and whether there is a fit. No obligation, and no proposal unless you ask for one.
