Manufacturing planning terms, explained

AI-assisted planning

Using artificial intelligence to help people understand planning data: spotting patterns, exceptions and risks, and pointing to where attention is needed. It supports decisions; it doesn't replace good data, good process or experienced staff. In MaXXflow, AI summarizes shortages, late supply and schedule conflicts, explains what's changed and highlights priorities. See AI in MaXXflow.

Allocated stock

Inventory that has been assigned or reserved for a specific job, order or requirement. It matters because stock can show as available when it's already committed; if another job tries to use it, one of the jobs comes up short. See Inventory and warehouses.

Anomaly detection

Spotting something unusual or unexpected in the data, such as unusual material usage, unexpected cost changes, odd purchasing patterns, repeated shortages or a job behaving differently from normal. Its value is catching issues that would otherwise be missed.

Audit trail

A record of changes and actions in a system: who changed what, and when. It creates accountability and makes it possible to trace BOM changes, stock adjustments, job updates or purchasing decisions. See Access, permissions and audit trail.

Barcode and QR code

Machine-readable labels that are scanned to identify items, locations, jobs or transactions. In manufacturing, scanning cuts manual entry and makes stock movements, job updates and material tracking faster and more accurate. See Barcode and QR scanning.

Bill of materials (BOM)

The structured list of components, materials, subassemblies and quantities needed to make a product. It's one of the most important inputs to planning: if the BOM is incomplete, outdated or wrong, the material, purchasing and production plans built from it will be too. See Bills of materials and EBOM vs MBOM.

Capacity

How much work a business or a resource can complete in a period of time. It can be limited by labor, machines, equipment, shifts, supplier availability or other constraints. You can have every material you need and still miss a date if the capacity isn't there. See Scheduling and capacity.

Dashboard

A visual summary of key information that shows status, risks and priorities at a glance. Different roles need different views: purchasing needs shortages and suppliers, production needs work orders and readiness, management needs delivery risk and performance. See Dashboards and reporting.

Delivery confidence

How far you can believe a promised delivery date is realistic. It depends on material availability, purchasing status, production capacity, job readiness and how visible the risks are. See Delivery dates you can't stand behind.

Demand

The requirement to make or supply something. It can come from confirmed customer orders, forecasts, minimum stock levels, service requirements or internal production plans. Demand is the starting point for MRP. See What is MRP?

Digital workflow

A structured process managed through a system rather than through disconnected emails, spreadsheets or manual handovers. It gives each step clearer ownership and visibility, and makes the process repeatable instead of reliant on individual memory.

Engineering bill of materials (EBOM)

The BOM as engineering designed it, usually from CAD, PDM or other engineering systems. It holds parts, assemblies and design structure, but often isn't ready for manufacturing on its own. See EBOM vs MBOM.

Enterprise resource planning (ERP)

A broad business management platform that may cover finance, sales, purchasing, inventory, production, service, reporting, HR and administration. ERP is usually much wider in scope than MRP. See MRP vs ERP.

Exception

Something that needs attention because it falls outside the expected process, such as missing materials, a late purchase order, stock below required levels, a job that isn't ready, an overdue action or an unusual cost change. Seeing exceptions is more useful than seeing more data. See Alerts and exceptions.

Inventory

The stock of materials, parts, subassemblies or finished goods a business holds, including raw materials, purchased components, work in progress, spares and consumables, in one location or several. The important question isn't how much you hold but whether it's available for the work that needs it. See Inventory and warehouses.

Item master

The central list of items, parts, materials, subassemblies and finished goods a business uses. Each record can hold a part number, description, unit of measure, supplier, cost, lead time, stock rules and category. See Getting your data ready.

Job

A unit of work the business needs to complete, which may relate to a customer order, an internal requirement, a project, a batch or a custom build. "Job" and "work order" are often used to mean similar things. Either way, a job has dependencies: materials, information, resources and timing. See Manufacturing and work orders.

Lead time

The time it takes to obtain, make or complete something. Supplier lead time is how long an item takes to arrive; production lead time is how long it takes to make; internal lead time covers steps like approval, picking or inspection. A cheap, simple part becomes a major risk if it takes eight weeks to arrive. See What is MRP?

Manufacturing bill of materials (MBOM)

The BOM as the product will actually be bought, assembled and produced. It may add items the design never modeled, consumables, production materials, packaging or process items, or group parts differently to suit purchasing and assembly. See EBOM vs MBOM.

Master data

The core records the whole system relies on: items, parts, suppliers, BOMs, warehouses, work centers, users and standard lead times. If item codes, BOMs or lead times are wrong, planning outputs will be wrong too, so getting master data ready is an early step in any implementation. See Getting your data ready.

Material requirements planning (MRP)

Working out what materials you need, how many, when, and whether you already have enough, using demand, BOMs, inventory, supplier lead times, purchase orders and work orders. Put simply, it turns demand into a plan for what to buy, what to make and what's at risk. See What is MRP? and Material requirements planning.

Planning risk

Anything that could affect your ability to buy, make or deliver as planned, such as missing materials, supplier delays, inaccurate BOMs, poor inventory visibility, capacity constraints, unclear job status or late engineering changes. The earlier it's visible, the more time you have to respond. See Alerts and exceptions.

Predictive reorder

Using demand, usage patterns, lead times and stock levels to suggest when items may need reordering, so purchasing can act earlier. It's decision support, not automatic purchasing: in MaXXflow, AI can highlight replenishment priorities, and people decide what to buy.

Production readiness

Whether a job is actually ready to start or continue. Appearing on the schedule isn't enough: it may still need an approved BOM, available materials, purchase orders that arrive in time, resolved engineering changes, released work orders, and available resources and work centers. See Manufacturing and work orders.

Purchase order

A formal request to buy goods or services from a supplier, with item details, quantities, prices, delivery dates and supplier information. An open purchase order shows what's on order, but it doesn't remove risk: the supplier may be late, deliver part of the order, or miss the date production needs. See Purchasing and suppliers.

Reorder point

The stock level at which a new purchase or replenishment should be triggered. For example, with a reorder point of 20, you reorder when available stock falls to 20 or below. In manufacturing, reorder points need to be weighed against demand, BOM requirements, lead times and job priorities, because one large order can create demand no reorder point was set for. See Inventory and warehouses.

Resource

Anything needed to complete work: a machine, person, workstation, production area, tool or process capability. Knowing which resources are available tells you whether you have the capacity for the work you've planned. See Scheduling and capacity.

Role-based access

Giving people permissions based on their responsibilities. A purchasing user might manage supplier actions while a production user updates work order progress. In MaXXflow, a privilege matrix controls view, create, update and delete permissions across modules, managed by role. See Access, permissions and audit trail.

Routing

The sequence of operations needed to make a product, such as cutting, machining, welding, assembly, inspection, painting and packaging. It shows how work moves through production and which resources each step needs.

Safety stock

Extra stock held to reduce the risk of shortages from demand changes, supplier delays, stock inaccuracies or unexpected usage. Too much ties up cash and space; too little risks disruption. The aim is the right stock, not simply less of it. See Cash tied up in the wrong stock.

Scheduling

Deciding when work should be done and in what order. A schedule can look organized and still be unreliable if it doesn't reflect material availability, capacity, job priority and production constraints. See Scheduling and capacity.

Shortage

When you don't have enough available material to meet demand or support planned production. Causes include low stock, late purchasing, incorrect BOMs, unexpected usage, supplier problems and poor visibility of allocations. The goal is to find shortages early enough to act. See Shortages found too late.

Source of truth

The place people go for the most accurate, current information. In many businesses it's unclear: one person trusts a spreadsheet, another the accounting system, another a phone call. See No single view of jobs, stock and purchasing.

Stock on hand

The quantity of an item physically held, or recorded as held. It isn't always free to use: it may be reserved, allocated, awaiting inspection, in another location or needed for a higher-priority job. See Inventory and warehouses.

Supplier lead time

The time between ordering an item and receiving it. It decides when purchasing has to act: if an item takes six weeks and the job starts in three, the shortage is already serious. See Purchasing and suppliers.

Unit of measure

How an item is counted, bought, stored or used: each, meters, kilograms, liters, sheets, rolls or boxes. Errors cause purchasing, inventory and production problems, for example buying in boxes but using individual units. See Getting your data ready.

Warehouse

Any location where stock is stored. That might be a formal warehouse, or a stores area, production area, service van, branch or project site. Knowing where stock is matters as much as knowing how much exists. See Inventory and warehouses.

Work in progress (WIP)

Items or jobs that have started production but aren't finished. WIP represents material, labor and value already committed, so poor visibility of it makes job status, capacity and delivery risk hard to judge. See Manufacturing and work orders.

Work order

An instruction or record defining manufacturing work to be completed: what's being made, the quantity, the materials, the due date and the status, and sometimes labor or production steps. Creating a work order doesn't make the job ready; that depends on the BOM, materials, purchasing and production requirements. See Manufacturing and work orders.
