Operations
Throughput, reliability, safety, and cost across industrial, energy, and manufacturing sites — where the work actually happens.
Four Lenses Advisory
Four ways of seeing the same operation, so nothing gets missed.
Four Lenses Advisory helps business owners, buyers, and founders — and the advisors who support them — turn industrial, energy, and manufacturing operations into measurable value, anytime: whether the business is running fine and ready to run better, headed toward a sale, freshly acquired, or raising capital to grow.

The method
One operation. Four lenses.
Most reviews look through a single lens and stop. We examine the same business four ways, then reconcile what each view reveals into one prioritized plan.
Value
The owner's and investor's view: capital efficiency, margin, cash conversion, and what drives — or drains — enterprise value.
Process
Lean and Six Sigma discipline: reduce variation, remove waste, and make good outcomes repeatable rather than heroic.
Organization
Structure, decision rights, and ownership — so improvements hold after the engagement ends.
What we do
Engagements built around a decision.
Operations improvement
Diagnostic reviews and improvement roadmaps for industrial, energy, and manufacturing operations — focused on efficiency, reliability, and unit cost.
Learn moreBusiness efficiency & value generation
Where margin, working capital, and overhead are leaking — and the shortest path to recovering them.
Learn moreOwner, buyer & founder advising
A candid, investor's-eye review — anytime, not just around a deal: for owners building value, buyers standing up operations after a close, and founders preparing to raise capital.
Learn moreOrganizational process development
Turn how the work gets done into documented, owned, measurable processes that survive turnover.
Learn moreWhat tends to change
Fewer surprises. Clearer priorities. Value you can point to.
Every engagement is different, but clients typically leave with the same things in hand.
- A ranked list of the improvements that matter, with the size of the prize next to each.
- An operating view and an owner's view that finally agree on the same numbers.
- Waste and variation identified at the process level — not just described in a slide.
- Named owners and a cadence, so the plan keeps moving without you pushing it.
- A cleaner story for lenders, buyers, boards, and co-investors.
About
Built by an operator who reads a business like an investor.
Four Lenses Advisory is the practice of Brad Caldwell — a chemical engineer with 30 years in the petrochemical industry and an MBA from Rice University, who pairs that operating record with three decades as an active investor.
The result: your operation examined the way a buyer or investor would examine it — capital, margin, risk, and what a third party would actually pay — and pointed at the moves that build value.
