Project revision checklist: what to confirm before customer approval

A project rarely reaches approval without changes. Dimensions are corrected, products move, finishes change and the customer asks to compare alternatives. The risk is not the revision itself. The risk is allowing different teams to continue from different versions.

A short review routine makes the current state visible before the proposal leaves the company.

Identify the revision clearly

Use a revision identifier that appears in the project file, the bill of materials and the quote. Record the date and the reason for the change. A file called “final” does not show whether it came before or after “final-corrected”.

The identifier does not need to be complicated. It needs to be consistent and visible wherever the project is used.

Confirm what changed

Do not review the entire project as if it were new. Start with a change list and verify the areas affected by each item:

• layout and circulation;
• product dimensions and quantities;
• finishes and optional accessories;
• installation points and clearances;
• bill of materials;
• commercial values and delivery assumptions.

A dimensional change may affect more than the selected object. A longer run of shelving, for example, can alter end components, accessories and the total occupied space.

Regenerate connected outputs

When the drawing is the source of project information, regenerate the bill of materials after every approved change. Do the same with the quote or the data sent to the ERP.

Avoid correcting exported spreadsheets manually. A manual adjustment breaks the relationship between the drawing and its outputs and may disappear the next time the project is generated.

Check removals as carefully as additions

Added items are easy to notice. Removed items are more likely to remain in a quote, purchase request or production list. Compare quantities before and after the revision and investigate unexpected differences.

Also confirm whether the change leaves an accessory without its parent product or creates a combination that is no longer valid.

Make the approval explicit

Record which revision the customer approved and keep the approved document linked to the corresponding project. If another change arrives, open a new revision rather than silently replacing the approved one.

Before releasing the project, verify:

• revision identifier and date;
• change list completed;
• layout dimensions and quantities;
• finishes and accessories;
• regenerated bill of materials;
• regenerated quote;
• customer approval tied to the same revision.

A reliable revision process does not add bureaucracy. It removes uncertainty about which project should be quoted, purchased and manufactured.
