Flagship

Throughput and downtime study

A multi-day plant visit that traces lost hours from stop logs, cycle times, and the line itself, then returns a visual brief factory managers can act on.

Operators working along a production line inside a manufacturing hall

Who it is for

Plant and production managers who need a defensible picture of where hours disappear across one hall or a small group of lines.

What you take away

A written visual brief covering planned versus unplanned stops, first-hour losses after changeovers, and the few stop reasons that consume most of the week.

Scope

Typically one hall or up to four connected lines, observed across two to four production days plus a records day.

Included

  • Opening walk with the production lead to agree which lines and which week of records to use
  • Review of shift logs, stop codes, and planned maintenance windows you already keep
  • Timed observation of selected operations, changeovers, and start-ups
  • Charts of lost hours by reason, by shift, and by day — drawn for print and for a short briefing
  • A closing session with the factory manager to walk the charts on the floor, not only in a meeting room

Not included

  • Software licences, sensors, or a standing login to any system
  • Union or disciplinary work
  • Redesign of the factory layout as a construction project

Who attends

Content Crafthub — industrial study lead plus one observer on larger halls.

How it runs

Enquiry, records list, visit dates, on-site work, draft charts for comment, final brief.

Time

Usually five to eight working days in total, of which two to four are on the plant.

Where

On the factory floor and in the production office. We travel from Camer's Green, Worcestershire; most visits are in England and Wales.

What to prepare

Shift logs and stop codes for an agreed recent period, a named escort, and access to the lines during ordinary running — not a staged demonstration.

Limits

We do not interrupt safety procedures. Night shifts can be included when arranged in advance.

Fees

Quoted from a day rate plus travel. A typical four-line hall study starts from the figure shown on the fees page. See the fees page for day rates and starting figures.

Next step

Write with the plant postcode, number of lines, and whether night work is in scope.
