Consider an engagement that looks correct on every measurable dimension. The counterparty is serious. The work is well within the firm’s capability. The terms are reasonable. The reputational risk is low. The economics are favourable. The brief is clean. By every conventional measure, the work should be accepted.
There is a second set of measurements that does not appear on the brief. Does this engagement displace work the firm would otherwise be doing. Does it shape the firm in a direction the firm has not chosen. Does the counterparty’s expectation, over time, pull the firm into a posture it would not have chosen freely. The answers to those questions matter as much as the brief.
The discipline is to decline work that fails the second set, even when it passes the first. This is not always intuitive. The defensible engagement is often the wrong one. The decision feels imprudent in the moment and proves correct only across years.
The work the firm accepts is not separable from what the firm becomes. Every engagement is a small contribution to the firm’s identity. A reasonable engagement, repeated, becomes the firm’s character. The firm that wishes to remain selective must be selective in the moments where selectivity is hardest to defend.
