A glimpse of David Maister's thinking.
Technical excellence is the price of admission, not the source of competitive advantage. Maister's core conviction is that professionals who make their clients' interests structurally more important than their own billings will outperform those who optimize for utilization rates and engagement margins. The firm that earns genuine trust, and organizes itself internally to deliver it consistently, wins the work that never goes to competitive pitch.
