For a professional services firm, the rule that says which proposals to pursue: bid where fees won per hour of pursuit in that cell of practice, source and fee band exceeds a stated floor; require a partner's written case where it does not. From the proposal log, engagement letters and pursuit-coded time entries.
A thirty-four percent win rate describes no cell. Strategy tenders at five percent and existing clients at sixty-eight are the finding.
Without hours coded to proposals, the cost is spent and unmeasured.
Fees won divided by hours spent bidding, by source and size, from the proposal log and timesheets. The rule names the combinations below a stated return and says not to bid, or to bid only with a named sponsor.
Invited proposals to existing clients win 55 percent and return $4,100 of fees per bid hour. Open tenders to strangers win 9 percent and return $350. The rule: no open tenders without a partner who knows the buyer.
Win rate is watched and bid cost is not. A team can raise its win rate by bidding on small safe work and still lose money on pursuit.
