Briefing: reading an operating model in ninety minutes
Before any engagement is scoped, we spend ninety minutes reading the operating model from evidence: the calendar, the minutes, the approval trails. This briefing records the session in full, on an anonymised client, so you can run it on yourself.
The briefing walks through the diagnostic in the order we actually run it. First, the calendar audit: whose time the executive committee actually spends, on what, and how far that is from what the strategy says matters. In the recorded session, the gap is 61% — three of every five leadership hours went to subjects the strategy does not mention.
Second, the decision trace: the last ten significant decisions, timed from necessity to communication. The recorded organisation averaged 29 days, with the longest — a pricing decision — at 96. Third, the initiative register: everything in flight, tested against the question nobody asks out loud: who would notice if this stopped?
What the ninety minutes reveals
The session ends with three numbers on one page: the attention gap, the median decision latency, and the load ratio — initiatives in flight against measured capacity. Together they describe the operating model as it is, not as the organisation chart draws it. In our experience the room recognises the description immediately; it has simply never seen it written down.
The instruments used in the session — the calendar audit template, the decision trace protocol, and the load register — are published in the framework library and may be applied without licence. The briefing closes with the question the diagnostic exists to sharpen: not “is the operating model good?” but “can it carry what you are about to ask of it?”
