Shane Ian Murphy: A Cambridge Decision Log Should Preserve the Reason

A project record can show what a team decided and still fail to explain the decision. Months later, a colleague sees that one option was chosen over another, but the reasoning has disappeared into a meeting nobody can reconstruct. My preference is to preserve enough of that reasoning to make a future review possible, without turning every ordinary choice into a long report.

I am Shane Ian Murphy, also known as Shane Murphy, formerly of Cambridge and formerly of Limitless Mobile, where I was co-founder and Chief Business Development Officer. This UK business commentary uses a hypothetical Cambridge project to explore a practical writing habit. It does not describe a real client decision or claim a measured business result.

Imagine a small team preparing a printed welcome booklet for visitors to a shared workshop. They choose a short booklet with a separate sheet for opening arrangements, rather than putting everything into one publication. At the time, the reason seems obvious: the opening arrangements are still being tested and may change. If the record says only “use separate sheet”, that reason will become harder to recover.

I would begin a decision entry with the question being answered. In this example, the question is how to provide stable introductory information while keeping changeable details current. That wording helps a future reader understand the choice on its own terms. It prevents the decision from being mistaken for a general preference against including practical information in a booklet.

Next, record the chosen approach and the alternatives seriously considered. The record does not need every idea mentioned in passing. It should preserve the alternatives that explain the tradeoff. A single booklet might be easier to distribute, while a separate sheet might be easier to replace. Describing those consequences is more useful than saying that one option was more flexible.

The reason should identify the information that mattered at the time. The team may know that the opening arrangements have not yet settled, but it should not turn that observation into a claim that they will change frequently forever. A decision record should distinguish a current condition from a prediction. That distinction matters when the circumstances later become more stable.

I would include important assumptions in a form that can be checked. For the workshop, the team might assume that someone will replace the separate sheet whenever its details change. If nobody accepts that responsibility, the chosen approach may not work as intended. Naming the assumption connects the decision to the practical arrangement it depends on.

The record should also explain the decision's scope. Choosing a separate sheet for opening arrangements does not necessarily establish how the team will handle every future update. Scope prevents an ordinary choice from quietly becoming a rule for situations nobody discussed. It also gives colleagues a clearer basis for recognising when they need a fresh decision.

A review condition is often more useful than an arbitrary reminder. The team could agree to revisit the format once the opening arrangements have remained settled for a defined period, or when preparing the next print run. The appropriate condition depends on the work. What matters is that a future reader can identify the change in circumstances that would make reconsideration worthwhile.

I would keep the entry short enough to maintain. A workable structure might contain the question, choice, principal reason, important assumption, responsible person and review condition. A few clear sentences under those headings can preserve more useful context than a long chronological account of the meeting. The record is there to support future work, not to reproduce every exchange.

Later, a new coordinator may ask why the practical information is supplied separately. The decision log should let them see that the arrangement responded to uncertainty at a particular stage. They can then judge whether that uncertainty still exists. They do not have to treat the old choice as either an unquestionable rule or an unexplained mistake.

For me, that is the value of recording reasons. A decision becomes easier to maintain because people can recognise the conditions that supported it. In a Cambridge workshop or any UK team, a useful record lets the next person continue the reasoning rather than merely inherit the result.
