A Timeline Worksheet for Three Versions of a CCTV Installation Proposal

Why three versions need a timeline, not a memory

Three versions of a proposal rarely arrive in a tidy sequence. One may be a printed cover page handed over at a meeting, one may be a file uploaded to a shared folder, and one may be a revised copy sent after a review conversation. By the time a decision is needed, the person holding the folder is often working from memory about which copy is newest.

A timeline worksheet solves a narrow problem: it records what each version claims about itself, when it appeared, and when it was reviewed. It does not decide which version is best. It gives you a defensible administrative record so that a question like "which document did we agree to discuss?" has an answer that does not depend on recollection.

This worksheet is written for premises managers in Sarawak comparing proposals for ordinary security-system work. The dates below are invented examples used to show the method. Your own dates will differ, and the provider should confirm them.

The three records to ask the provider to confirm

Before filling in any dates, decide which administrative records you will treat as authoritative. A compact set of three is usually enough for a proposal file:

First, the cover page date. This is the date printed on the front of the proposal itself. It is the version's own claim about when it was issued.

Second, the upload date. This is the date the file was placed in whatever shared location both sides use, such as a project folder or a document portal. It is a record of when the file became available, not when it was written.

Third, the review date. This is the date on which the proposal was discussed, questioned or marked up by the people who will approve it.

Ask the provider to confirm each of these in writing, even briefly. A short message that states the cover page date and the upload date for each version is enough to anchor the worksheet. Where a provider plans, supplies and installs CCTV security systems, the proposal is the working document between survey and installation, so its dates matter to both sides.

Worksheet layout: one row per version

Keep the worksheet to a single page. Use one row per version and the same columns for each, so the three can be compared without hunting.

Suggested columns, in order: version label (for example, Version A, B, C); cover page date; upload date; review date; who confirmed each date; and a short note on what changed between this version and the previous one.

The version label should be your own, not the provider's. Labels like A, B and C are easier to track than file names that may repeat words such as "final" or "revised".

A worked example using invented dates: Version A carries a cover page date of 3 March, an upload date of 5 March and a review date of 12 March. Version B carries a cover page date of 20 March, an upload date of 21 March and a review date of 2 April. Version C carries a cover page date of 9 April, an upload date of 10 April and no review date yet.

That last blank is the useful part. An empty review date tells you Version C has not yet been discussed, which is a fact worth knowing before anyone treats it as settled.

Reading the gaps between the dates

The worksheet earns its keep when you look at the intervals rather than the dates alone. Three gaps are worth noting, and each is an example of a question to raise, not a rule about how providers behave.

Cover page to upload. A long gap may simply mean the file sat in an inbox before being filed. Ask which date the provider treats as the issue date.

Upload to review. A short gap suggests the document was discussed soon after it appeared. A long gap may mean the review happened against an earlier copy, which is worth clarifying.

Review to the next version's cover page date. This interval shows how quickly comments turned into a revised document. If the next version's cover page date falls before the previous review date, ask the provider to explain the sequence, because a revision cannot normally respond to comments made after it was issued.

None of these gaps is a fault on its own. The worksheet simply makes them visible so the conversation starts from a shared record rather than an assumption.

Where the proposal sits in the wider project

A proposal timeline is easier to interpret when you know what stage it belongs to. In a typical sequence, a site survey comes first, then a proposal, then installation and handover. The proposal dates should sit between the survey and the work itself.

If the worksheet shows a proposal reviewed before any survey took place, note that. Camera placement decisions are usually informed by a survey, so a proposal that predates one may be based on assumptions that a later survey could change. This is a reason to ask, not a reason to reject.

Eyonic CCTV, also known as Eyonic Security Systems, plans, supplies and installs CCTV systems for homes, offices, shops and industrial sites in Sarawak, and its published service list includes site survey, camera placement, NVR setup and remote viewing. Those are the stages a proposal normally describes, which is why the document's dates are worth tracking against them. You can read more about the installation side of that work on the CCTV installation services page.

A short confirmation message to send

Once the worksheet is drafted, send one message that asks the provider to confirm the three records for each version. Keep it plain and specific.

An example wording: "We are keeping a record of the three proposal versions we hold. For each, please confirm the cover page date, the date the file was uploaded to our shared folder, and the date you understand it was reviewed. Please also confirm which version you consider current."

That last request matters. The worksheet records dates; it does not by itself establish which version is current. Only the provider can confirm that, and only in writing.

If the proposal includes door access as well as cameras, the same discipline applies. Smart locks work best when the door condition, user roles and backup method are reviewed before installation, and for business use Eyonic usually checks whether a standalone smart lock or access-control panel is more appropriate. A review date attached to that discussion is worth recording alongside the camera proposal dates.

Keeping the worksheet honest

A timeline worksheet is only useful if it separates what is confirmed from what is assumed. Mark each date with its source: confirmed in writing, taken from the document itself, or estimated. Never fill a blank with a guess to make the table look complete.

Review the worksheet whenever a new version arrives, and keep the earlier rows rather than overwriting them. The history is the point.

This worksheet is an administrative aid, not a substitute for the provider's own records or for any contractual terms. It does not assess whether a proposal is suitable, and it makes no claim about how long any stage should take. The invented dates above are illustrations of the method only.
