Left Brain Consulting · Nathan Harris

Between strategy and execution, something has to decide.

When something has to happen across teams that don’t report to each other, I’m the one who makes it land. I know what good looks like, I know what it all connects to, and I hold the teams to it until it’s real. Fourteen-day installs or fixed-scope repair — one lane, for a defined stretch, then out.

Knowledge-work environments preferred — software, professional services, tech-enabled operations. Where the constraint is cross-functional and the capacity is people.

In fourteen days you see the whole portfolio — active work and backlog — ranked against real capacity, with a decision on every item. The timeout that keeps the next one from being needed.

A diagnostic that keeps diagnosing — about an hour per team to stay current. Every structural gap it finds becomes a defensible business case for headcount.

Proof

Reallocated $5M of a $50M expense base to protect EBITDA inside a $100M ARR business unit — and it survived a change in leadership at the top with nobody in the room to defend it.

You already know what’s keeping you up at night.

ONE FLOOR SCOPED THE REST OF IT IS FINE

No diagnostic needed. We agree what done looks like before I start — in writing, with a date. Then I’m on the ground driving it with your team until it’s met, not advising from the side. If specialist build work is needed, I bring the person in and hold them to the same definition.

If more than one of these is true at once, that’s a timeout, not a fix.

Sounds like this
  • Two teams shipping into the same system with no agreed release order.
  • An acquisition closed and nothing got absorbed. Two of everything, and no one will pick.
  • A program that has slipped three times and nobody can say what actually caused it.
  • A build with no agreed definition of done, so it never quite ships.
  • A function that exists on the org chart but has no intake, no review, no escalation path.

Delivery standards
Proof

The delivery standards behind every one of these were built and pressure-tested alongside EY, IBM, Infosys and Cognizant, and with C-suite and SVP leadership inside Fortune 50 and Fortune 275 organizations. Fitted to how you already operate, not the other way around.

Who you’d be working with

Nobody hands you the title delivery architect.

I was put inside a Fortune 50 turnaround at 23 and handed the change control board — 50+ application development teams, 1,000+ executive change requests, on a $200M program overhauling a $2B business unit. It didn’t exist before me. The platform couldn’t go live without it.

Then I became the audit point of contact for that program, which meant seeing how every team actually operated against the standard rather than how they described it. Most operators know one function deeply. That year I got the cross-section — and that vantage point is the whole thing. I know how functions fail against each other, where decisions actually get made, and what has to exist before execution can hold.

Eight years, five promotions, Associate Director by 25. A $125M budget covering every enterprise system at a $15B company. A failed ERP consolidation I got handed the rollback of. A $100M ARR business unit running as three silos that I put behind one intake — still running today after the leadership that sponsored it turned over.

The short version

I build the layer that decides — and I build it to run without me. That constraint — that it has to survive without me — is what shaped every method on this page.
