Project Decision Log Preparation Checklist

Write down the choices that would be awkward or wasteful to reverse once materials are ordered or a surface is closed up, and treat those as the core of the log.

Reversibility is a more useful test than importance; a small irreversible choice usually deserves an entry more than a large one that can still be changed freely.

Note which choices are yours to make and which the professional has said they will make on your behalf, so neither side assumes the other has already settled it.

Assumed ownership of a choice is a common source of a gap in which nobody actually decided anything until the moment it was built.

Ask the appointed professional to confirm which decisions they need from you, and at what point in the works they normally need them.

Record choices about anything that will end up hidden behind a finish, since these become difficult to establish later and are rarely visible for checking afterwards.

Concealed items are the entries owners most often wish they had written down, since the alternative later usually means opening something up again.

Decide whether routine selections such as a paint colour sit in the same log as choices that affect layout, or in a separate list of their own.

Mixing very fine-grained selections with layout choices makes the log tiring to read, and a log that is tiring to read stops being maintained.

Keep conclusions about safety, consents and local requirements out of the log, and record instead the question you intend to put to a suitably qualified professional.

A log entry written as a conclusion tends to be treated as one later, including by people who were not part of the original conversation.

Statements about safety, consents and local requirements belong with a suitably qualified professional or the relevant local authority, not in an owner's notes.

Add an entry when you consciously decide to leave something as it is, because a decision not to act is still a decision that someone may query later on.

Deliberate inaction looks identical to an oversight once enough time passes, unless the reasoning was written down at the moment it was settled.

Decide the small set of fields every entry will carry, such as what was chosen, who chose it, what it applies to, and where the supporting message is filed.

A fixed handful of fields is far easier to complete consistently than a free-form note, and it makes gaps in the record obvious at a glance.

Choose a single ordering for entries, either by room or by trade, and hold to it rather than switching partway through the project.

Mixed ordering makes the log hard to scan at the moment someone asks what was agreed about a particular room or element.

Give each entry a short reference you can cite in a message, so a reply can point back to it without anyone restating the whole decision again.

A reference turns a long explanation into a shared shorthand, and it makes it obvious when two people are discussing different entries.

Decide whether the log is a shared document others can read, or a private one you summarise from when you need to send something.

A shared log invites correction, which is useful, but it also invites other people to treat your notes as an instruction.

If you intend to share the log with an appointed professional, ask them what they treat as a record and what they treat as an instruction.

Leave a field for status, so an entry can be marked as settled, provisional, or waiting on something to be established on site first.

Without a status field, provisional choices quietly harden into settled ones simply because they have been sitting in the log for a while.

Test the format by entering a handful of choices you have already made, and see whether the fields hold them comfortably before the pace picks up.

Reworking the structure is easy while there are only a few entries and painful once there are many spread across several rooms.

Record who raised the question as well as who answered it, since a choice prompted by a supply constraint may need revisiting if that constraint changes.

The origin of a choice tells you whether it still stands when circumstances move, which a bare record of the outcome cannot.

Note which household member confirmed a choice when more than one of you is involved, so a later objection can be traced rather than argued about.

Household disagreements surface late and are much easier to resolve when the record shows who agreed to what and when.

Write down what was actually in front of you when you chose, such as a physical sample, a sketch or a photograph on a phone screen.

Choices made from a screen and choices made from a sample regularly diverge, and knowing which one applied explains a later surprise.

Where a choice was made in a meeting or during a site walk-through, note that fact and who else was present at the time.

A choice made in front of several parties travels differently from one made in a private message, and the attendance list often matters later.

Ask the professional to confirm a verbal choice back to you in writing, and file their confirmation against the matching entry in your log.

Their wording is the version that will reach the site, so it is worth having alongside your own summary of the same conversation.

A choice that exists only in your notes may not match what the professional recorded; ask them to confirm their understanding in writing.

Avoid recording a choice as settled when it was only discussed, and use the provisional status until someone has confirmed it clearly.

Marking discussion as agreement is the most common way a decision log becomes less reliable than the memory it was meant to replace.

For each significant choice, note briefly what else was on the table, so you are not re-examining the same alternatives when the subject returns.

Without this, a well-considered decision looks arbitrary a few conversations later, and someone reopens it in good faith.

Record why an option was set aside, and whether the reason was your own preference or something you were told about the building.

Preference can change freely, while a reason grounded in the building may still hold and should be re-checked before the option is revived.

Where an option was ruled out on advice, note who advised it and what they said, without converting their advice into a general rule in your own words.

Advice is usually given about a specific situation, and it loses its conditions when it is paraphrased into something that sounds universal.

Advice about your building may not transfer to another situation; ask a suitably qualified professional again before applying it elsewhere.

Keep a short list of options parked rather than rejected, so that if a change becomes necessary you start from work you have already done.

Parked options are the fastest route to a fallback when a discovery on site removes the arrangement you had chosen.

Note any option that depended on something being established on site, and what would need to be found for it to come back into consideration.

These entries turn a discovery during the works into a decision you are ready for rather than one made hurriedly on the spot.

Resist writing the rejected option out of the record entirely, because the question of why something was not done tends to return at handover.

A record that shows only what was chosen invites the assumption that nothing else was ever considered.

Note the drawing or sketch version you were looking at when a choice was made, since reissued drawings can quietly remove the basis for an entry.

When a drawing is reissued, the version reference is usually the most dependable way to tell which of your entries need rechecking.

Photograph the sample or swatch you chose from and store the image with the entry, rather than relying on a written name alone.

Names for finishes vary between ranges and batches, and an image of what you were actually shown is far easier to reconcile later.

Where a selection carries a reference on a supplier sheet, copy that reference into the entry exactly as it appears on the document.

A reference transcribed loosely can point at a different item entirely, and the error usually surfaces only when something is delivered.

Record which room or element each decision applies to, and whether it applies to every similar element or only to that one.

Choices meant for one room have a habit of being applied everywhere, or of not being applied where you assumed they would be.

Note where a choice depends on another choice not yet made, and mark both entries so they are reviewed together rather than separately.

Dependent choices made in isolation are how two individually sensible selections end up incompatible with each other.

Ask what the professional or supplier needs from a selection before it can be ordered, and record their answer rather than assuming a name is enough.

Ordering information often includes details an owner would never think of, and the gap is usually discovered at the worst moment.

Ordering requirements differ between suppliers and installers; ask the responsible party what information they need and get it in writing.

Set a routine point at which you transfer choices out of messages and into the log, rather than trusting yourself to do it as they happen.

Choices arrive in bursts and usually at inconvenient moments, so a habit works better than an intention to capture each one immediately.

When something is agreed during a site visit, write the entry before you leave rather than reconstructing it from memory once you are home.

Details such as which element was pointed at fade very quickly, and they are exactly the details that matter in an entry.

Mark entries that were changed instead of overwriting them, so the earlier choice and the reason for the change both remain visible.

An overwritten entry hides the fact that a change ever happened, which makes an unexpected result on site much harder to trace.

Watch for substitutions offered on site, and log them as new entries rather than as a quiet amendment to the original selection.

A substitution has a different origin from your original choice and may carry consequences that the original selection did not.

Ask a suitably qualified professional whether a substitution offered on site affects anything else before treating it as settled.

Keep any entry that is waiting on something to be opened up or established clearly visible, rather than filing it away with the completed ones.

Waiting entries are the ones that get forgotten, and they usually reappear as a hurried decision made by whoever is on site.

Read the relevant entry before answering a question put to you on site, rather than replying from memory and creating a second version of the same choice.

An answer given from memory that differs from the entry is how a log stops being trusted by the people who were relying on it.

Before the works finish, read the log through for entries still marked provisional and ask what became of each one.

Provisional entries left unresolved are the most likely source of a surprise when you finally look closely at the finished work.

Ask the responsible professional to confirm the final position on any entry that remains open rather than assuming it was quietly resolved.

Note against each concealed item roughly where it sits, so a future occupant or tradesperson has some idea what lies behind a surface.

This is often the single most useful part of an owner's record once the project is finished and everything is closed up.

Collect the manufacturer literature and care information for the things you chose, and reference it from the relevant entries in the log.

Care requirements are easiest to gather while deliveries are still arriving and hardest to reconstruct once packaging has gone.

Decide what the log becomes after completion, whether a maintenance reference, a record kept for a future sale, or something you simply archive.

Deciding its purpose tells you what to keep in full and what can be summarised down to a line.

Read the log for anything that reads as a judgement about a person, and soften or remove it before the document is shared more widely.

A log you may later hand to a buyer or another professional is not the place for an assessment of anyone's performance.

Keep the finished log with the rest of the project papers rather than in a separate place that only you know about.

A record nobody else can find provides none of the benefit it was written for, particularly after the property changes hands.
