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.

Eight years inside Fortune 50 and Fortune 275 transformations: the change control board governing 50+ application teams on a $200M program, an enterprise PMO built from nothing, and the rollback of a failed ERP consolidation delivered with zero critical defects.

01The strategic timeout

Everything feels like a priority, so nothing is.

SCHEDULE · RANKED9.28.77.15.53.1CAPACITYLOAD 9 / 6 · OVERLOADED THE FILTER SURVEY OF EXISTING SHEET 01 · 14 DAYS AS FOUND STRATEGY EXECUTION

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.

What exists on Day 10

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.

02Symptom treatment

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.

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.

03Select opportunities only

When a timeout and a fix aren’t enough.

SPAN · NOT A VISIT TODAY AT SCALE

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.
