For a professional services partner, the fee value of their clients' matters worked by other practices over the fee value of all their clients' matters. Read beside the client gap against the firm's norm, never alone.
A partner whose clients are single-practice by nature has a low share and no gap. The gap is the finding; the share is context.
Originating partner and working practice on the matter record. Where the practice field is unreliable, use the fee earner's practice from time entries.
The fee value of a partner's clients' work done by other practices, divided by the total fees of those clients.
Partner A's clients paid $3.0 million, of which $1.1 million was for work in other practices: 37 percent. Partner B's clients paid $2.6 million and $90,000 went elsewhere in the firm.
Only origination credit tracked. Who introduces colleagues to their clients is not.
