Change that fades
compelled me to resolve for
Change That Holds

My work did not begin as a framework. It began as a problem I could not solve.

For seventeen years I built and ran a business growth agency serving technology companies selling into enterprise. It was commercially demanding work. Revenue targets were real. Procurement cycles were complex. Growth was not conceptual; it either translated into contracts or it did not. I learned very quickly that strategy must survive pressure.

At the same time, I worked for six years within regulated financial services, preparing funds firms to meet regulatory scrutiny. That environment required clarity. Governance structures could not be vague. Accountability could not be aspirational. If something failed under examination, it failed visibly.

Alongside both of these careers, I was deeply engaged in personal development. For over twenty years I invested time, money and effort into behavioural change, mindset work and transformational systems. I trained extensively. I applied what I learned with sincerity and discipline. Often, the results were striking at first.

And then they faded.

Patterns returned. Capacity dropped. Momentum dissolved. I would start again, often with greater insight and greater commitment, and still the change would not stabilise.

It became difficult to ignore the parallel.

In enterprise, growth would accelerate and then fracture under structural strain. In regulated firms, carefully designed initiatives would unravel if governance was unclear. In personal development, insight alone was never enough if the underlying system could not sustain the load.

I would discover the underlying pattern to be architectural. 

My interest shifted entirely to resolving that architecture. I returned to formal education in mind psychology and body psychotherapy. I revisited the modalities I had trained in and examined them through a different lens. Over time, what emerged was a structure: change holds when capacity is solvent, constraints are understood, and the order of change is respected.

Human Operating System Architecture grew from that work. It integrates biological capacity, structural constraints and lawful sequence into a coherent system for durable change. It is informed by commercial growth under pressure, regulatory governance in practice and the lived experience of change that repeatedly failed to last.

My focus is Change That Holds.
