A new machine has a visible price. An unclear handover has a quieter cost: a purchase made against an old specification, a batch waiting for approval or a delivery promise that production never saw.
Before adding capacity, a small manufacturer can learn a great deal by following one order through the existing operation. Ask each person what information they receive, what they check and what makes them stop work.
Make one version of the order
The working record should identify the product, quantity, specification revision, agreed delivery date and any acceptance requirements. Changes need an owner. A message in a sales group should not silently become a new production instruction.
Keep the format simple enough that the team will use it. The objective is not a thick procedure manual. It is a shared answer to the question: what exactly are we making for this customer?
Count interruptions, not just output
For a week, record why work pauses. Missing material, unclear drawings and quality queries are different problems. Combining them into a single downtime number hides the action required.
Ask whether a larger operation would reduce each interruption or repeat it at greater scale. Buying capacity does little for a process that regularly waits for decisions.
Test the next shift
Can someone who did not attend the sales discussion complete the job from the written record? Can the next shift see what remains unfinished? Can dispatch verify that the accepted version is the one being shipped?
Those questions turn expansion from a purchase decision into an operating decision. A second line makes more sense when the first one can reliably pass information as well as material.
