A shortlist is useful only when every candidate is compared against the same item, movement, system and acceptance target.
01 / 現場ノート
Define the unit
Decide whether the workflow identifies an item, case, pallet, tool, container or another unit. Record the hierarchy when multiple levels coexist.
02 / 現場ノート
Describe the environment
Record surface, liquid, metal, density, temperature, chemicals, attachment, lighting and operator conditions that can change the read or replacement process.
03 / 現場ノート
Compare the interaction
Choose between mobile, workstation and fixed patterns based on where the operator or item is during the event. Include tags, antennas, mounts and software in the comparison.
04 / 現場ノート
Compare the complete scope
Include media, encoding, readers, antennas, mounting, network, application work, integration, training, support and replacement effort. A device-only shortlist hides the operating decision.
05 / 現場ノート
Set an acceptance target
Define what counts as a useful result: read coverage, event correctness, operator time, exception handling, system posting and recovery. Measure it with representative samples.
06 / 現場ノート
Record and retest the choice
Keep the candidates, tested conditions, configuration, observations, rejected cases and acceptance decision together. Re-test when the item, site, workflow or system boundary changes.
