Measure time spent looking
For one week, record how long it takes to find the quantity and location of a selected item or lot.
Count repeated entries
Notice how often the same movement is written in a register, copied to a sheet and sent in a message.
List decisions delayed
Record instances where a purchase, production or dispatch decision waits for a stock check.
Use the evidence
These observations can help decide whether a digital register would help. They are not a promised saving; measure again after a change.
A practical starting point.
Every business works a little differently. Map your own workflow and check any accounting or compliance decisions with the people responsible for them.
