What Template Fields Document a Bag Specification?

Most specification documents are written rather than filled in. Someone opens a blank page when a style is developed, writes what they know, and the result is a document that answers the questions that happened to come up that week. Two styles from the same programme then look nothing alike.

A template fixes that. It is a form with a fixed set of fields, and its whole value is that the same nine are filled in every time, including the ones nobody wanted to answer. The unfilled field is visible, which is the point: an omission in a written document is invisible and an omission in a form is a blank box.

A template also settles an argument before it starts. Where two people disagree about whether a property was specified, the form answers it: either the field is filled in or it is not, and a blank box is a decision recorded rather than a discussion to be had again on every booking.

What Is a Specification Template Actually For?

Three jobs. It makes omissions visible, so a missing tolerance is a blank rather than a silent absence. It makes two styles comparable, so a reader can find the same field in the same place. And it makes the document survivable, so a person who joined last month can read it without being told the history.

The third job is the one that matters in a reorder programme. Specifications are read years after they were written, by people who were not there, usually in a hurry and usually because something has gone wrong. A form is much better at that than prose.

Which Nine Fields Does Every Template Need?

Header, materials, construction, measurements, tolerances, artwork, evidence, change control and sign-off. Nine, in that order. The order matters because a reader looking for one thing should always find it in the same place, and because the last three are the ones most often left out.

Two more items earn their place in the header on a running programme: the destination market and any claim attached to the product. Both change what a field is allowed to say, and both are usually buried in an email thread rather than sitting on the document that governs how the bag is made.

Templates also fail when they are too long. A form that asks for forty fields is a form that gets filled in once and abandoned, which is worse than a nine-field form that gets used. Nine is not a magic number, but it is close to the largest set a programme will actually maintain over several years.

How Is the Header Written?

Style code, colourway, revision number, approval date, the named owner on each side, and the location of the retained reference. Six items, and the revision number is the one that does the work, because it is the field cited on the purchase order.

Add a line for the superseded revision. A reader who can see what this document replaced can answer the question that arrives with every drift: was this run made before or after that change.

The discipline that makes this section work is refusing adjectives. Strong, durable, heavy-duty and good-quality are not specifications and cannot be checked. A line that cannot be checked is a line that will be satisfied by whatever the purchase that week delivered.

How Is the Material Section Written?

One line per material, named to four fields: brand or mill, material, finish and code. Body fabric, lining, foam or padding, webbing, thread, fasteners, hardware, labels and print. Nine lines covers most bags, and a line left blank is a material nobody has specified.

Where a material has a certificate or a test report, put its reference on the same line rather than in an annexe. The reader who is checking the foam wants the density, the grade code and the certificate in one place, not in three.

Position

Body, lining, padding, webbing, thread, fastener, hardware, label, print

Supplier

Mill, maker or brand, named rather than described

Specification

Fibre, weave, coating, thickness, grade or ticket

Code

The supplier product code for that combination

Finish

Plating, coating, print method or surface treatment

Evidence

Certificate or report reference, and the retained sample location

Where a style has a version history - a revised base, a moved pocket, a reinforced handle - put it in this section rather than in the log alone. A reader who can see what the construction used to be can tell whether a measurement in an old comparison sheet describes the same bag as the one being booked now.

How Is the Construction Section Written?

As a seam map plus a stitch specification plus an assembly sequence. The seam map says where each seam runs and what type it is. The stitch specification gives the count, the thread and the needle. The assembly sequence says what is joined in what order, which is the part that decides whether a repair is possible.

Name the reinforced points explicitly: handle attachment, strap anchor, base corners, zipper ends. Those are the places a bag fails, and they are the places most often left to the discretion of the line.

Write the units on every line. A dimension without a unit, a mass without a unit and a thickness without a unit are all readings that will be misunderstood at some point, usually by someone working from a copy of the document that has been translated.

How Is the Measurement Section Written?

As a list of named points, each with the state of the bag, the tool and the nominal value from the approved run. Length at the base seam, empty and laid flat, steel rule. Five or six points is typical, and the state and the tool are what make the value checkable.

Add mass. A finished bag has a mass, it is quick to record, and it is the single measurement that catches a material substitution across several lines at once. A bag that is twenty grams lighter than the reference has changed somewhere.

There is a case for adding a seventh column: who reads the property. Some readings are taken on the line, some at final inspection and some only by a laboratory, and saying which is which tells a reader how quickly a question about that property can be answered.

How Are Tolerances Presented?

Next to the measurement, in the same row, as a band with a method. Property, nominal value, band, method, position, and what happens when the reading sits outside the band. Six columns, one row per property, on the same table as the measurement rather than in a separate section.

One sentence in this section saves a great deal of time later: where each item is physically kept. A reference that exists but cannot be found is, for the purposes of the next comparison, a reference that does not exist, and it is the most common failure in programmes that otherwise keep good records.

How Is Evidence Referenced?

Three lists: retained references and where they are stored, test reports with their dates and issuing laboratory, and the comparison sheets from previous runs with their run numbers. Three lists, and each entry should be findable by someone who has never seen the cupboard.

The third list is the one that makes the document a programme record rather than a product description. A specification that points at four previous comparison sheets carries the history; one that does not has to be re-discovered on every booking.

Where a programme has several styles sharing one component, note that on the evidence list too. A shared fastener or a shared foam grade means one discontinuation affects several documents, and a reader who can see the shared lines can plan one decision rather than discovering three.

How Is Change Control Carried on the Template?

As a revision log at the foot of the document: one row per change, with the date, the field affected, the reason, who authorised it and which run it took effect from. Five columns, and the last one is the field most often missing.

A change takes effect from a run number, and that number belongs on the log. Without it, a reader cannot tell whether run four was made before or after the change agreed in March, which is exactly the question a drift investigation asks first.

One more field is worth a mention even though it is not one of the nine: the packing and marking requirement. Carton size, labelling, pallet pattern and any retail packaging belong on the same document, because a packing change is a change and is otherwise recorded nowhere at all.

What Does a Completed Template Contain?

One page per style and colourway, nine fields filled, a revision in the header, a sign-off at the foot, and no blank boxes. Where a field genuinely does not apply, it carries a dash rather than being left empty, because a dash says somebody decided and an empty box says nobody looked.

It should also be legible to a newcomer. That is the practical test: hand the document to someone who has never seen the style and ask them what the bag is, what it measures, and what has changed. If they can answer from the page alone, the template is working.

Keep the blank template in one place and issue copies rather than letting people rewrite it. A specification that has been reformatted for one style is a specification that will be compared with the others field by field and found to be missing three of them, usually at the worst possible moment.
