A production line can be running without producing enough usable product. In a battery factory, the commercial question is not simply how many cells enter the process. It is how many leave it meeting the requirements for their intended use.
Count what reaches the customer
Consider two otherwise similar production runs. One needs repeated inspection and rework; the other passes smoothly through the agreed checks. Even if they begin with the same materials, they use time, equipment and working capital differently. Good output is the result that matters to the next customer.
Yield needs a boundary to be useful. A figure measured at one machine is different from a figure covering the whole factory. A product awaiting final testing should not be casually counted alongside one ready to ship. The definition belongs next to the number.
Improvement has to survive the next run
An operator investigating losses might separate incoming material problems, process variation and damage during handling. These lead to different remedies. Buying another machine will not necessarily solve an unstable input, just as changing a supplier will not fix a poorly controlled process.
For a young manufacturer, a convincing demonstration is repeatability across ordinary production conditions. That includes keeping records when something goes wrong. The business needs to know whether an improvement persists, what it costs to maintain and whether it changes the product delivered to the customer.
