Practice Areas
Most engagements touch more than one practice. You get one partner, one team, and one plan — not four separate workstreams competing for your calendar.
Portfolio choices, market entry, and growth strategy grounded in evidence — not trend decks. We pressure-test the plan against your real capacity to execute it.
Margin and performance improvement that survives contact with the shop floor and the service line. We work inside the operation, alongside your teams, until the numbers move.
Operating models and restructures designed around how work actually gets done — with the leadership alignment and change support to make them stick.
Pragmatic digital work: fix the data, automate the obvious, and sequence the ambitious. No platform sales, no pilots that never scale.
How We Work
Every engagement follows the same discipline, whether it lasts six weeks or eighteen months. It is deliberately unglamorous — and it is why our recommendations get implemented instead of shelved.
We start with your data, your customers, and your front line — not with a hypothesis we brought with us. The diagnostic is shared in full, including what it says about our own fit for the work.
Weeks 1–3 · Fixed feeOptions are costed, sequenced, and argued in the room with your leadership team. We recommend one course of action and state plainly what we would not do — and why.
Weeks 3–5 · Joint decisionOur partners stay embedded while the plan becomes operating reality: new processes, structures, and routines designed with the people who will run them.
Months 2–6 · Embedded teamWe measure against the baseline from the diagnostic, hand over the dashboards and the habits, and leave. A good engagement ends with your team stronger — not dependent.
Final phase · Measured handover
