Taktora Engineering Notes
Deep dives into scheduling, constraints, and the human logic behind modern factory floors.
Reduce Changeover Time by Optimizing Sequence, Not Just SOPs
Most operations try to reduce changeover time by refining standard operating procedures. Teams time every task, trim wasted motion, and train technicians to move faster. This approach produces diminishing returns. The largest gains come from creating a sm...

Work in Progress in Production Scheduling: A Guide to Control and Reduction
Work in Progress, or WIP, accumulates when a production schedule fails to account for the physical realities of the factory floor. Excess WIP is not a random event; it is the direct, physical result of releasing work based on theoretical capacity rather t...

Why Spreadsheets Are Killing Your Production Schedule
Most manufacturers use spreadsheets to run production scheduling. It is the default tool because it is familiar, flexible, and already installed. It works when operations are simple. But as your facility grows, adding more lines, products, and constraints...

Why Waiting for Perfect Data Kills Your Production Schedule
Manufacturing decisions cannot wait for perfect information. On the factory floor, production schedules become outdated within hours as run rates shift, changeovers extend, and materials arrive late. Waiting for complete, validated data before adjusting t...

Why High Machine Utilization Doesn’t Always Improve Production Performance
High machine utilization is a misleading metric that often harms overall production performance. While keeping equipment busy seems productive, it can increase work in process (WIP), extend customer lead times, and make your entire operation fragile. True...
