Earlier Products

Pre-AI-era product and UX design work — an award-winning iOS panorama app shipped before the iPhone had one, hardware UX for Gallagher's farm weigh scale range, a regulatory browser tool for EECA, and an online will builder where trust turned out to be harder than simplicity.

Demystifying Business Analysis
The Methodology Made Visual

Every engagement follows the same underlying logic — understand the problem before designing the solution, map the people before writing the requirements, build the evidence before making the case.

The BAD methodology isn't a framework I've borrowed — it's the working logic extracted from twenty years of practitioner engagements, made explicit enough to teach. Five phases. Twelve artefacts. One consistent thread from problem statement to delivery.

The phase maps below show how that logic actually unfolds. Each phase has its own diagram. The full journey map shows all five in sequence. The artefact relationship map shows how they connect and depend on each other.

This is the methodology the BAD guide is built around — and the same logic I bring to every engagement.

Artefact Relationship Map
How the twelve artefacts connect — which depend on which, where rework loops run.
An insatiable appetite for understanding and something genuinely useful surfaces

My work sits at the intersection of how organisations operate, how information flows, and how people make sense of complexity. I work across process engineering, service design, systems thinking, and visual communication — often on the same project.

The challenge is always to come out with observations and insights — and then to articulate those in meaningful ways that inform decisions.

Let's make something worth seeing

If you have a complex problem that needs to be made legible — to a team, a leadership group, or the people doing the work — I'd like to hear about it. Currently available for process engineering, service design, and systems thinking contracts in NZ and remotely.
