Principles of Consulting Leverage
Key economic levers governing law, consulting, and advisory firm profitability:
- David Maister's 3-Pillar Law: Profit Per Partner is the product of three multipliers: Margin ($Profit / Rev$), Productivity ($Rev / Head$), and Leverage ($Heads / Partner$).
- The Leverage Multiplier: In a pyramid structure, junior consultants generate billing revenue that significantly exceeds their base salary and overhead, flowing directly to partner equity distributions.
- The Realization Trap: Discounting rates or writing off unbilled WIP hours rapidly degrades profit margins because staff salary obligations remain fixed.
- Downtime Risk: A highly leveraged practice experiences catastrophic profit swings if client demand dries up, as fixed payroll burns through reserves.
