Work-in-process tracking: knowing where every job is on the floor
How to track work in process across production stages: what to record, mobile, line and countertop recording, WIP inventory, bottlenecks and job status visibility.
Work in process (WIP) is everything that has started production but is not yet finished: materials issued, parts partly machined, batches waiting for packaging. WIP tracking tells you where each job is, how much is good, how much was scrapped and what is waiting. Without it, planners guess, customers get vague answers about delivery dates and WIP inventory hides losses.
What to record at each stage
Keep recording minimal so it actually happens:
| Data | Why |
|---|---|
| Job order and stage or operation | Where the work is |
| Quantity completed (good) | Progress and yield |
| Quantity rejected or scrapped, with reason | Quality and cost |
| Start and end time, or hours | Productivity and labor cost |
| Operator or team | Accountability and training needs |
| Machine or line | Capacity and maintenance |
| Downtime and reason | OEE and improvement (OEE guide) |
Choosing how the floor records
| Method | Best for | Watch out for |
|---|---|---|
| Mobile recording by supervisors | Areas without fixed stations; walking supervisors | Supervisor workload; late entries |
| Line stations | Continuous or assembly lines | Station placement; dust, heat and durability |
| Countertop terminals | Benches, workcells and packing tables | Shared logins; keep each user separate |
| Paper travelers encoded later | Transitional only | Delays, errors and no real-time view |
Recording at the point of work, as it happens, is the goal. Daily encoding from paper is better than nothing but loses the real-time view.
WIP inventory and valuation
WIP is an asset on the balance sheet: materials issued plus labor and overhead applied, less completed goods transferred out. If WIP is not tracked by job and stage, month-end WIP balances become estimates. Accurate WIP tracking supports job order costing and the month-end close.
Finding bottlenecks
WIP piling up before a stage usually signals a bottleneck. Track:
- WIP quantity and age before each stage
- Throughput per stage per shift
- Queue time vs. processing time
Improving the bottleneck raises output for the whole plant; improving other stages often just increases WIP. Lean methods help (lean manufacturing).
Job status visibility for sales and customers
With live WIP data, sales and customer service can answer "when will my order be ready?" without calling the plant. A simple job status view (released, in progress by stage, completed, delivered) removes many daily interruptions for production staff.
Common WIP tracking problems
- Completion recorded only at the end, so WIP looks frozen then jumps
- Scrap not recorded, so yields look perfect and costs look wrong
- Jobs closed without reconciling materials issued vs. used
- Several jobs combined on the floor but recorded separately in the system
Getting started
- Define the production stages for each product family.
- Choose the recording method per stage.
- Train supervisors and operators with real jobs.
- Review WIP reports daily in the production meeting.
- Close jobs promptly and reconcile material usage.

Frequently asked questions
What is work in process?
Production that has started but is not finished, including materials issued and labor and overhead applied to incomplete jobs.
How do you track work in process?
Record job progress, good and rejected quantities, time and downtime at each production stage, ideally at the point of work.
Why is WIP important for costing?
WIP is an inventory asset. Accurate WIP tracking supports correct job costs and month-end valuation.
What does high WIP indicate?
Often a bottleneck, poor scheduling or quality problems causing rework and waiting.
