No Surprises Is The Whole Of The Relationship
A board can absorb almost any bad news, and almost never absorbs finding it out from someone else.
The single operating principle that keeps a chief executive and a board functional is that no director should learn something material about the organisation from anyone but the chief executive, and preferably not on the day it becomes urgent. This is not about disclosure obligations, which are their own matter and require proper advice. It is about the mechanics of trust. A board that has been surprised once begins to wonder what else it does not know, and that wondering expresses itself as more questions, more reporting, more involvement in detail, which is exactly the dynamic the chief executive least wants.
The principle has an inconvenient consequence: you must raise things while they are still ambiguous. Waiting until you understand a problem fully means waiting until it is large, and the delay itself becomes part of what the board is assessing. The practice worth building is a short, plain call or note as soon as something looks like it might matter, framed honestly as incomplete. Here is what I know, here is what I do not, here is when I will know more, here is what I am doing meanwhile.
This works only if the board responds to early warning proportionately. A board that turns every early signal into an agenda item and a working group teaches its chief executive to wait, and will then be genuinely surprised later and blame the wrong thing. The chair's role here is decisive: to receive information early without immediately mobilising the whole board around it, and to distinguish between being told and being asked to act. Where that habit exists, the relationship is durable. Where it does not, no amount of reporting discipline compensates.
