Checking the first piece before the batch runs

This story shows a practical response to no batch runs until the first piece is signed off.

Before

A written rule changes the choice: only the signed current revision is released to regular production. The difficulty is applying the rule to real exceptions. The routine depends on the development engineer knowing which call, slip or instruction matters. Records exist in latest approved drawing, trial notes, inspection record and customer approval, but another person cannot reliably reconstruct the decision. This is the problem behind checking the first piece before the batch runs.

A request arrives and somebody responds to the loudest part first. The original source is left in a folder or WhatsApp chat. Later, when the quality manager needs to review it, people reconstruct what happened from memory. The missing piece is often drawing revision, sample settings, measured dimensions and written approval. By the time it is found, another person has already acted on an assumption.

The cost is visible as interrupted work, repeated checking or a promise that needs correcting. No saving or improvement figure is claimed here. The point is to change one repeatable action so that the next case can be handled without a chain of calls.

Why it was like that

The previous method relies on informal permission and experience. Staff may understand the right thing to do, but not where to record it or who can approve an exception. Adding a shared spreadsheet without clarifying authority would leave the same bottleneck in place.

In this example, the control that is missing is only the signed current revision is released to regular production. An urgent request can legitimately break the normal rule. The exception still needs a named decision-maker, a reason and a source reference. Otherwise the exception becomes the usual way of working.

The change

The replacement is a one-page sample and drawing approval file. Measure first-off part against current drawing. This is the required check before an instruction moves to the next person. Sign before batch release. Finally, record correction if out of tolerance. Each line retains the evidence needed if the decision is challenged later.

Copyable rule for this team

Example register rows, for illustration only:

The owner can set a sample limit, but it should be based on actual financial exposure, not copied from another firm. A rule that touches statutory dues, credit, worker pay or electrical safety also needs a qualified reviewer.

After

In the revised composite routine, the first person records the incoming request once. Another team member can see its source, status and next action without recontacting everybody. The quality manager sees only the cases needing judgement. Routine cases move under written delegated authority.

For the specific case in this article, the first visible change is measure first-off part against current drawing. The next person can then sign before batch release. At the end, record correction if out of tolerance. That sequence matters because each part leaves a record that the next role can verify.

A weekly check samples a few entries rather than trusting the tick column. The manager looks for cases marked closed without supporting evidence, repeat exceptions and requests that still depend on the owner. Those are reasons to revise the rule.

What to watch out for

• Staff may start filling the register after the event. Check the time and reference against the source.
• The authorised manager may approve an exception by phone and forget to record it. Ask for the decision to be added to the same entry.
• The team may treat every request as urgent. Compare actual deadlines and commercial or safety effects before changing priority.

Trial conditions must be reproducible in normal shifts. A one-off sample made by a specialist is insufficient.

Copy it

Use the table above as a starting point. Replace the example entries with two current cases. Mark unclear evidence as Open, then name the next person to check it. Keep the source record, owner, next review date and reason for any override. An example exposure of ₹36,800 or 46 units is illustrative only; set limits from your own business records.

Start with First piece approval checklist. If you need the full sequence, use First article inspection. Measure open exceptions and missed commitments for four reviews before deciding whether the change holds.
