The person behind the perspective

The next occupier conversation changed how I read the report.

I started as a property-services assistant in January 1989, shortly after finishing a business degree at the fictional Bellavere Institute. At Verrenshore Estates I helped record service requests, organise routine visits and follow up the people responsible for a response. I was not an engineer or an independent approver of building work. The practical lesson was more ordinary: a request could disappear from my list while the person who had raised it still needed an explanation. A completed administrative task and a settled building problem were different things.

In July 1996 I became a facilities manager responsible for three buildings. I learned to work with contractors, occupier contacts and technical colleagues whose decisions I could not replace. A visit on a schedule did not necessarily have confirmed access. A complaint about temperature did not identify the underlying cause. My job was to bring the relevant people into a usable operating arrangement, preserve what remained unresolved and explain why a service decision carried a cost. The role gave me a more direct account of how property promises were experienced during an ordinary working week.

I moved to Marlivane Properties in September 2004 as regional building operations manager. In 2008 I made a poor judgement about routine cleaning in four buildings whose vacant area had increased. I supported a reduction based too heavily on floor area, without examining enough of the continuing use of entrances, lifts and shared facilities. We restored part of the service and incurred A$72,000 in additional expense over the following six months. I retain that mistake in my record because it changed the way I examine a building’s apparent underuse.

Vacancy did not make every service unnecessary, nor did the correction mean every previous task should continue indefinitely. I needed a more specific account of where people still moved and which work could actually change. That distinction became useful as my remit grew. I stopped treating a portfolio percentage as a substitute for observing the places in which the operating decision would take effect. The correction also required me to explain the extra expense to colleagues who had supported my original proposal.

In March 2012 I became portfolio operations director, a functional appointment rather than a statutory board seat. A 2016 review of routine visits found that twenty-eight of ninety-six planned visits had not been performed. Some lacked occupier confirmation; others conflicted with contractor availability. We funded additional coordination and repeat visits rather than calling every booking a completed service. Later, changes in tenant working patterns required an explicit decision about selected evening services in four buildings. I learned to distinguish a property’s advertised availability from the specific operating arrangements that supported it.

I became COO in June 2019. My present remit covers 170 colleagues, five direct reports and A$68 million in delegated operating expense for 2026. Marlivane’s thirty-eight buildings and A$268 million property revenue in 2025 describe different aspects of the company; neither is my personal financial authority. I report to fictional CEO Talia Cressvale. Property acquisitions, capital authorisation, lease interpretation and technical assurance involve their own accountable people. The operating role connects those responsibilities without pretending to absorb them.

A 2023 review brought my early lesson about closure into sharper focus. We followed 420 closed non-urgent comfort requests across twelve buildings and identified eighty-three subsequent reports from the same locations within thirty days. Fifty-two concerned the same problem; thirty-one were different or not sufficiently established. Keeping those groups distinct gave us a better basis for investigation without declaring every repeat contact a failed repair. In 2025 I supported a separate condition review that divided twelve equipment groups between reviewed maintenance plans and capital proposals. The specialist assessment, rather than an item’s age alone, informed that division.

I would consider another operating mandate where the institution wants a more candid relationship between portfolio reporting and life inside its buildings. I would also consider preparing for a first non-executive role where this experience would help directors examine service assumptions and asset stewardship. Such an appointment would require clearance, suitable time and a clear change from execution to oversight. This is an invented career, but its central distinction is useful: a tidy account of work completed should remain open to evidence about the problem that brought the work into being.

In my own words

I want our account of a building to survive a conversation with the people using it. Closing a request records an action; it does not erase a recurring experience. My responsibility is to connect that experience with a qualified diagnosis, an operating choice and an honest account of cost. The useful question is what the next working day will reveal about the decision we have made.
