Left Brain Consulting · Nathan Harris

Between strategy and execution, something has to decide.

I come in when the decision layer is broken, the floor is failing, or the gap is wider than the team inside can close. Fourteen-day installs, scoped fractional work, or full-time when the need is real.

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. I come in, get up to speed, and run the playbook — solve the constraint with your team, train them to operate it without me, and move on to the next one.

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

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.

SPAN · NOT A VISIT TODAY AT SCALE

Fig. 03 The span between today and at scale, held rather than visited

Substantial growth, substantial change, or substantial reduction — the moments where one person has to make everything work better at once. That’s a right hand, not an engagement.

Not a fractional engagement with a longer end date. A seat, with the mandate that comes with it.

Proof

Eight years inside MetLife and IQVIA — change control across 50+ application teams, a $125M enterprise systems budget, and a failed ERP consolidation rolled back with zero critical defects.

Who you’d be working with

Nobody hands you the title organizational 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. Then I leave, and it keeps running. That constraint — that it has to survive without me — is what shaped every method on this page.
