A firm of six to twenty-five people hits a wall that effort cannot break. The teams work hard; the partners work harder. Yet quality varies by who did the file, moving staff between teams costs weeks of relearning, and the honest answer to “where are we?” takes a day to assemble. The instinct is more supervision. The fix is the opposite: an operating process that needs less of it.
Recognise the pattern
Three symptoms mark the transition. First, three teams, three processes: GST, audit and accounting each evolved their own steps, file names and review standards, so consolidated quality is an average, not a standard. Second, partners as the workflow engine: allocation, chasing, escalation and re-prioritising all route through the people with the least spare capacity, so growth makes the bottleneck worse. Third, rework absorbing the margin: corrections and reopened review notes are unbilled - they never appear on an invoice, only in the year-end profit.
None of these is a people problem. They are what naturally happens when a practice grows faster than its operating model.
What “one operating process” actually means
It is not a binder. It is a small set of firm-wide decisions, made once and enforced by systems rather than memos: one documented way to run each service line, with SOPs and checklists people actually use; working papers structured and named the same way on every engagement; maker-checker gates with turnaround targets; tasks routed by rule instead of by partner; and one secure channel for client documents.
The role of technology is to make the standard the path of least resistance. A workflow tool that encodes the firm's process makes following it easier than deviating; a portal that gives clients one channel makes the side channels wither; a dashboard fed by the workflow makes status a view instead of a meeting.
Sequence it around the calendar
Rollouts fail at firms this size for one predictable reason: they collide with a filing peak. The sequence that works is quarterly - standardise one service line, wire its workflow, measure a cycle, then move to the next. Discovery and design in the quiet weeks; launches immediately after a peak, never during one. Three to four quarters covers most firms without a single heroic month.
The payoff is optionality
A firm on one operating process can absorb a new joiner in days, move staff to wherever the season needs them, quote for institutional work with evidence of its controls, and give partners back the hours that supervision was consuming. Growth stops adding load to the busiest people, which is the whole point.
