Water Bottling Line Bottleneck Diagnostic

Use one bottle and pack configuration, a stated start and finish and one accepted-output count point. Record normal operating conditions and any material, staffing or utility changes. If the evidence comes from different shifts or SKUs, keep it separate instead of turning mixed observations into a single diagnosis.

• Enter a short non-confidential run description; leave proprietary settings, credentials and personal details out.
• Use “not yet measured” when the observation was not checked. Use “not observed” only for the chosen run.
• If every answer is unknown, establish a baseline first. If every answer is no, the six reported symptoms are absent from that observation, not every possible loss.

Starved states point the investigation toward missing supply; blocked states point toward a downstream restriction. Neither names the component responsible. Review the first relevant event, neighboring machine states and buffer movement. An independent example has a packer stop, an accumulating conveyor and a later filler-blocked state. Summing every machine stop would count overlapping time more than once; the filler alarm alone would not justify a filler replacement.

• Align machine clocks before interpreting event order; uncertain timestamps remain uncertain evidence.
• Note buffer occupancy before and after the event, not just whether the conveyor eventually became full.
• A restriction can move with the SKU or recovery sequence. Recheck another run before applying one finding to every format.

The checklist routes positive observations to supporting records. Several positive answers may describe one propagating event, separate losses or an unresolved combination. It deliberately does not score a “most likely failed machine.” Use the bottleneck guide for causal reasoning and the loss Pareto for measured priorities after the records are reconciled.

• Trend a utility condition against the actual loss interval; coincidence alone does not establish causation.
• Separate rejected, held and accepted units at defined count points so a quality loss is not hidden in gross output.
• Collect observations through approved systems and qualified personnel. Do not open guarded areas, bypass interlocks or alter operating limits for this tool.

The result stays in this browser tab session where storage is available. It is not an enquiry submission. Continue to the same-language line-review form to inspect or remove the summary, then provide your contact details and production requirement. Editing or clearing the diagnostic invalidates the previous result. If storage is unavailable, the checklist still works but you must copy the relevant non-confidential details into the form yourself.

• State the current accepted output and the required condition separately; neither a catalog rating nor this checklist proves a recoverable gain.
• Request a data review before selecting an upgrade, spare or service scope. Mark unresolved observations explicitly.
• Use the acceptance record when a proposed intervention needs a reproducible before/after comparison.
