Taktora Engineering Notes
Deep dives into scheduling, constraints, and the human logic behind modern factory floors.
Best Certifications for Production Planners
The best certifications for production planners come from APICS, now part of the Association for Supply Chain Management (ASCM). The Certified in Planning and Inventory Management (CPIM) is the primary credential for planners. The Certified Supply Chain P...

How Far Ahead Should You Plan Production
The ideal production planning horizon is a rolling 2 to 4 weeks for detailed, finite scheduling. Longer-range forecasts, from 3 to 12 months, should inform this detailed plan but remain flexible. This approach balances the need for shop floor stability ag...

MRP vs APS Which System Your Factory Needs
MRP tells you what materials to buy and when. APS creates an optimal production schedule based on your factory's real capacity. MRP plans for resources. APS sequences the work. Modern manufacturing operations require both systems to function effectively....

How Finite Capacity Planning Eliminates Production Bottlenecks
Production bottlenecks are the single biggest threat to your on-time delivery rates and profitability. They create gridlock, increase work in process, and force expensive schedule changes. Finite capacity planning directly solves this problem. It creates...

Taktora vs Spreadsheets: Why Excel Fails Production Scheduling
Spreadsheets are the most common scheduling tool in manufacturing. They are also the most common source of scheduling failure. From small job shops to mid-size contract manufacturers, the pattern repeats: a planner builds a detailed schedule in Excel, som...

Manufacturing Capacity Planning: How It Works and Where It Fails
Manufacturing capacity planning determines how much a facility can produce, whether it can meet demand, and where the gaps are. Done well, it prevents overcommitting to customers and prevents machines from sitting idle. Done poorly, it produces numbers th...

What Is a Master Production Schedule (MPS)?
A master production schedule tells a factory what to build, how many to build, and when to have it ready. It sits at the center of manufacturing planning. Every downstream operation, material purchasing, labor scheduling, machine loading, depends on it be...

5 Signs Your Factory Needs AI-Powered Production Scheduling
Most manufacturers know something is wrong before they can name it. Orders ship late. The floor is always reacting. The schedule from Monday is irrelevant by Tuesday morning.

Production Scheduling Software: What It Does and How to Choose One
Most manufacturers hit a point where their scheduling process stops working. Orders pile up. The floor is busy but not always working on the right things. A rush order arrives and it is not clear what to move to fit it in. Someone rebuilds the spreadsheet...

Manufacturer Standard Lead Time Explained
Manufacturer standard lead time is the planned duration between order release and completion under assumed normal conditions. While it provides a baseline for quoting and planning, it often diverges from reality due to bottlenecks, variability, changeover...

Why Spreadsheets Are Killing Your Production Schedule
Most manufacturers run their production schedules in spreadsheets. It is the default choice. It feels familiar, it costs nothing extra, and it works well enough when you are small. But as volume grows, as your product mix expands, as shift patterns get mo...
