Reporting to a board that wants one number

Reporting to a board that wants one number. What it costs, who decides, and what usually goes wrong.

For an independent reference point, see SANS security policy templates.

The ask

A board wants one number and there is not one

The request is reasonable. Compliance does not produce a single figure that means anything, and inventing one is how programmes end up reporting green in the month before a failed assessment.

Four numbers work, and they should be the same four every month.

The four

What to report

Controls with current evidence, as a proportion. Not controls implemented: controls for which evidence exists and is recent. The gap between those two is the interesting part.

Open remediation items, by severity. A count and a trend.

Confidence in the date. Stated as a range with the reason for the range, not as a single date that never moves until it moves by a quarter.

Spend against plan. Including internal time, priced, for the reasons the entry on cost gives.

The percentage trap

Ninety per cent is not ninety per cent of the way there

Requirements are not equal. Ten unmet requirements can be trivial or can be the ones that fail an assessment, and a single percentage hides which.

Worse, once the percentage is the reported number it becomes the managed number, and the cheapest way to raise it is to satisfy easy requirements first. That is the wrong order: the hard ones need the lead time.

Report the percentage with the count of high-severity items beside it, always, so that neither can be read alone.

Bad news early

The rule that keeps a programme credible

A date that slips is a normal event. A date that slips having been reported as safe the previous month is a credibility event, and the second is much more expensive than the first.

Report a risk when you first believe it rather than when it materialises. Boards absorb early warnings and remember late ones.

The format

One page

The four numbers at the top. Three lines on what changed this month. Three lines on what is at risk and what is being done. One decision or request, if there is one.

Anything longer is read by nobody and produces questions about whatever appears on the page the reader happened to open.

What not to report

Control-by-control detail

It is the material the owner works from and it is not a board paper. Presenting it invites a discussion of individual controls with people who cannot evaluate them, and it consumes the meeting.

Keep it available as an appendix nobody reads and refer to it if asked.

External reporting

What goes outside the company

Separately from internal reporting, suppliers submit self-assessment scores into a government system, and primes ask their supply chains for status. Those numbers are visible to customers and they should be consistent with what the board is told.

Where they diverge, somebody has been optimistic in one direction, and the divergence is discoverable.

Rests on

The requirement to submit self-assessment scores and the system they are submitted to are set out in the relevant defence acquisition regulation clause.

Which submissions apply to a given supplier depends on their contracts.

Frequency

Monthly, and the same day each month

Quarterly is too slow to act on and weekly is noise. A fixed monthly slot that happens whether or not there is news establishes the habit, and the month with no news is the shortest paper you will ever write.

The question you will be asked

Are we going to make it

Answer it directly, with the confidence range and the two things that would change it. An owner who answers with a percentage of controls has not answered, and will be asked again in a form that is harder to handle.

The appendix that earns its place

One chart, not a table

Controls with current evidence, plotted monthly since the start. It answers the trend question without discussion and it makes a flat month visible, which a table of the current figure does not.

When there is nothing to report

Say that

A month where the numbers did not move because the work was documentation is a legitimate month. Reporting it plainly is better than manufacturing progress, and it prepares the ground for the months where the numbers move quickly.
