Downtime and utilization
How to run a weekly downtime review that fixes causes
Put five blocks on one page, take the top reason down to a cause someone can change, and check each fix against a target set in advance. Worked example inside.
Operations and lean
Add a shift, buy a machine or recover lost hours?
Recover lost hours first, add a shift when you can staff it and buy a machine when you can’t. Each route priced per good part on one CNC lathe, by hand.
Downtime and utilization
How to know mid-shift whether you will hit target
Compare the count with the goal to now, project the shift at its current pace, and use the stop budget to see whether a gap can still be recovered.
Downtime and utilization
How to reduce machine downtime, one cause at a time
Cut unplanned downtime in four steps: record every stop, rank reasons by hours, split each into how often and how long, then fix it. Worked CNC example inside.
Operations and lean
When to replace a spreadsheet production schedule
An Excel schedule fails once one change has effects nobody sees. Learn the five signs, what each replacement checks, and how to move your open jobs across.
Operations and lean
Production scheduling on real run rates
Schedule from the rate each machine really runs, not its ideal cycle time. Turn measured OEE factors into job durations, pick a rate and load machines safely.
Operations and lean
How to find the bottleneck machine, with numbers
The bottleneck is the machine with the least spare time for its load. Calculate load, check busy time and queues, and prove it with lost hours. Worked example.
Downtime and utilization
Planned vs unplanned downtime and what counts against OEE
Breaks, changeovers and planned maintenance are all downtime. See which count against OEE availability, with one shift worked three ways and a decision table.
Downtime and utilization
The true cost of idle machines
An idle machine keeps costing you depreciation, floor space, idle power and any operator waiting at it. Price an idle hour, and learn when it costs output too.
Machines and connectivity
What manufacturing data to collect, and how to collect it
Collect machine state, part counts, stop reasons and scrap first. See what sensors, controllers and operators each capture, and what to ask a vendor.

How SCADA differs from IIoT and cloud monitoring
SCADA supervises and controls a process from PLC data. IIoT collects machine data for analysis. Learn what each does, where they meet and when to run both.
