Insights on production scheduling, lean manufacturing, and manufacturing software from 35+ years of industry experience.
How the platform actually works: scheduling, optimization, the shop floor and ERP data.
What Is Global Instance Assignment in Scheduling?
Global instance assignment keeps one job on the same machine instance for every shift it occupies on a work center, trading a little load balance for setup continuity.
What Is Greedy Scheduling in Manufacturing?
Greedy scheduling plans one job at a time, taking the earliest feasible slot at each step and never revisiting it. Fast, always feasible, and predictably suboptimal in one specific way.
What Is Open Quantity on a Sales Order Line?
Open quantity is what a customer is still owed: ordered quantity minus shipped, floored at zero. See how it drives firm demand and shrinks as shipments post.

What Is Positional Column Mapping in a Data Import?
Positional column mapping reads each field from a numbered column instead of a heading name. Learn when a headerless file needs it and the risk it carries.
What Is Quantity on Hand in Inventory?
Quantity on hand is the current stock figure for a product, held as a cached total the ledger owns. Learn why you never type it and how it stays correct.
What Is Routing Drift in Production Scheduling?
Routing drift is the gap between the routing a job was scheduled against and the routing that is live today. Learn what the shop floor is told about it, and why the job keeps its own copy.
What Is Row-Error Tolerance in a Data Import?
Row-error tolerance decides whether one bad row fails alone while the import continues, or stops the whole run. Learn both behaviors and when to use each.
What Is Sales Order Reference Grouping in an Import?
Sales order reference grouping gathers file rows sharing one order reference under a single sales order and auto-numbers their jobs. Learn how it works and when to leave it blank.
What Is the Delay Composition Order in Scheduling?
Queue time, lot-streaming overlap, and transit days are applied to a finished operation in one fixed order. Learn the sequence and why the order changes the answer.
What Is the Labor and Material Cost Basis on a Quote?
A quote's estimated cost is labor plus material: hours times each work center's rate, and material from routing steps or the product unit cost. Learn the exact rule.
What Is a BOR Change Type in Routing Comparison?
A BOR change type classifies how a routing differs from the snapshot a job was scheduled against: work center, timing, requirements, sequence, or structural.
