(How a six-week pause, a bit of arithmetic, and a dose of honesty changed everything)

The Moment of Truth

“Sixty per cent,” I said.

The room fell silent. Not polite silence – real silence. The kind that stretches.

BT’s senior team stared at me as if I’d spoken another language.

My CEO’s leg started bouncing around under the table – a nervous reflex he couldn’t control.

He was terrified of what the BT executives would do next.

No one in our company – or any other supplier, for that matter – had ever given BT a number that low.

But it was the truth.

And the truth, as it turned out, was the most powerful lever in the room.

For the first time in years, something changed.

That’s how the Independent Program Review was born – though we didn’t call it that at the time

It began quietly, with arithmetic, honesty, and the courage to stop pretending.

A Program That Had Become a Tradition

When I took over a national telecoms program for BT, it had been limping for so long that it had stopped being a scandal and become a tradition.

It was a multi-year effort – already more than five years old and showing every sign of running indefinitely.

BT no longer believed the reports.

The suppliers no longer believed each other.

And my own organisation – the Prime Contractor, responsible for bringing it all together – had perfected the art of saying “almost there” with a straight face.

The monthly reviews were pure theatre: optimism performed, disbelief politely expressed, and everyone pretending to be reassured.

PowerPoint had become the drug of choice. Progress was the casualty.

Contrived outrage gave the illusion of accountability, but nothing ever changed.

The Outsider’s Advantage

I wasn’t from telecoms. I came from the computer industry – from a world of advanced silicon, operating systems, and complex systems software.

Rigour was expected there, not optional. That turned out to be my greatest advantage.

That’s not to say it wasn’t expected in telecoms too – it was – but the organisation was still some way down the capability curve, adapting from its electromechanical roots to the emerging world of software and systems.

I wasn’t an engineer myself, but I understood how complex systems fit together and how to organise the people who build them.

That, in the end, is what programs are about: bringing together highly qualified specialists and interlocking systems to deliver something coherent.

I didn’t do anything others couldn’t have done – I just came at it from a different place, and I followed the rules of disciplined execution.

It’s amazing what happens when you stop managing noise and start managing truth.

When Truth Went Missing

The engineers had stopped being heard.

They were bright, capable people trapped in a structure that valued obedience over truth.

They felt they had no option but to pretend they could get the job done, then take another pasting at the steering committee the following month.

I encouraged them to be truthful. I listened.

I told them, “I can’t fix what you won’t tell me.

It’s remarkable how quickly progress begins once people stop having to defend the indefensible.

You could almost hear the relief in the corridors.

Fixing the Thinking, Not the People

Within weeks, it was obvious that the problem wasn’t the people – it was the thinking.

When deadlines slipped, management reached for the only lever they understood: add shifts, squeeze harder, push faster – or cut functionality.

They were trying to debug software as if it were a gearbox.

After one especially painful client review – part confession, part pantomime – I decided never to attend another meeting like it.

There was no reason the next would be any different: more guesses, more lies, more broken promises.

So, I asked the mahogany mafia in BT for a six-week stay – no new commitments, no new dates.

I needed time to find out what was actually true.

For six weeks, the noise stopped. The theatre closed. And the real work began.

Arithmetic and Pattern Recognition

Back at base, we stripped the program to its bones.

Arithmetic came first. We built metrics, traced dependencies, and compared ambition to physics.

Then came pattern recognition – spotting where effort evaporated, where suppliers collided, and where bright engineers were buried under managerial archaeology.

Six weeks later, I went back with a plan that finally added up.

BT, ever methodical, asked for a confidence rating – something they’d been requesting for years, though no one had ever dared quantify.

“Sixty per cent,” I said.

My CEO’s leg started bouncing under the table – again.

He was terrified of what the BT executives would do next.

But instead of anger, there was silence – followed by something rarer.

Respect.

The BT team didn’t feel they were being shafted by yet another Prime Contractor.

For the first time in years, they felt someone was levelling with them.

And that feeling – trust – became the foundation for everything that followed.

Credibility Over Comfort

Telling them “60% confidence” took courage. But behind that was clarity: credibility matters more than comfort.

Afterwards, several of BT’s top brass said they found the candour refreshing – that it gave them belief, not doubt.

For the first time, they said, they believed the program could succeed, because the way ahead was transparent and logical.

What they didn’t know was that I’d worked quietly with my opposite number inside BT.

We’d agreed that honesty would serve us both better than the theatre of optimism that had defined previous years.

That small act of trust changed everything.

Once trust entered the room, progress followed. Every time.

The Birth of a Method

Clients value truth far more than theatre.

They may wince at first, but they respect clarity – because it means you’ve done the thinking.

Without realising it, we had just carried out the first Independent Program Review.

We stepped outside the noise, examined the system objectively, and told the truth.

Arithmetic gave us the facts; pattern recognition explained the failures; leadership turned insight into action.

Years later, when Mentor was formed, this became our method – formalised, teachable, repeatable.

But its DNA was born in that six-week pause, when a nervous CEO, two sceptical suppliers, and one tired client finally agreed that honesty beats optimism.

That’s when we discovered the secret most leaders never learn: Truth is the fastest route to delivery.

The Old Guard – the JFDI aristocracy – believed leadership meant setting impossible targets by decree and daring reality to keep up.

The New Guard knows better: credibility comes before control.

You can’t manage what you don’t understand, and you can’t understand what you refuse to measure.

What Has Changed

Prince2 and its sisters haven’t changed anything.

They’ve given us more forms, more frameworks, and more process vocabulary – but the outcomes look the same.

Decades later, technology has changed beyond recognition – 5G, AI, hyperscale infrastructure – yet the execution truths remain stubbornly familiar.

What has changed is the mindset of a new generation of leaders.

A growing number of enlightened executives – many who’ve lived through program fiascos – are no longer content to watch the same story unfold.

They’ve seen the movie before, and they’re determined to rewrite the ending.

They’ve realised that independent scrutiny isn’t a nuisance – it’s insurance.

That rigour, arithmetic, and honesty deliver more progress than a thousand dashboards.

That single hard truth, spoken early, can save millions later.

And that courage in the short term protects credibility in the long term.

Because the truth is: people don’t change much – and neither do the reasons they fail.

But some, at least, have stopped pretending the old, failing ways are best.

They’re the ones who will change what Prince2 never could: how complex programs actually get delivered.
