A statement of monthly capacity does not prove that a bathroom order can be produced in the required window. Buyers need evidence of process fit, current loading, material readiness, bottlenecks and recovery planning. This guide explains how to evaluate capacity and scheduling without relying on factory size, machine counts or unsupported output claims.
Separate capability, capacity and availability
Capability asks whether the proposed process can make and verify the exact product. Capacity asks how much that process can produce under stated assumptions. Availability asks how much of that capacity remains in the required period after other confirmed work and maintenance are considered. All three must align.
A site may have relevant equipment but lack approved materials, trained operators, fixtures or inspection time for the selected model. Conversely, a supplier may coordinate several qualified processes rather than own every operation. The buyer should examine the proposed order route and control responsibilities instead of equating ownership with deliverability.
Map the order through actual process steps
| Evidence | What it helps establish | Question to ask |
|---|---|---|
| Process flow | Required internal and external operations | Which step controls the overall rate? |
| Sample or trial record | Product-process fit and expected checks | Was the quoted configuration actually reviewed? |
| Loading plan | Confirmed work in the requested period | What time is truly available for this order? |
| Material plan | Input availability and decision dates | Which items depend on buyer approval or replenishment? |
| Bottleneck calculation | Rate assumption at the limiting step | Does it include changeover, yield and downtime? |
| Milestone schedule | Dependencies from approval to shipment | Who owns each release and recovery action? |
For a vanity, the flow may include material receipt, machining, edge or surface work, assembly, hardware fitting, top or basin coordination, inspection and packing. For an illuminated mirror, it may include glass processing, component preparation, lighting and electrical assembly, powered testing, labelling and protective packing. Identify outsourced steps and transport between sites.
Ask for a capacity calculation with assumptions
A useful calculation starts at the bottleneck. It states available shifts or hours, demonstrated cycle time, changeover, planned downtime, expected yield and product mix. It should distinguish theoretical machine speed from sustainable good output. If several sizes or finishes share the same process, the schedule must account for switching and batching.
Request the period and scope behind every number. “Units per month” is meaningless without the model mix, number of working days, shifts, process boundary and whether the result represents gross output or accepted finished units. Buyers do not always need the supplier’s full confidential plan, but they do need enough evidence to understand the commitment.
Review the current loading position
Ask for an anonymized loading view covering the proposed production window. It can protect other customers’ identities while showing confirmed work, tentative reservations, maintenance and available slots. Compare this with the quotation schedule. A promised date should have a visible place in the plan.
Clarify what reserves the slot: quotation acceptance, deposit, approved drawing, material release or another milestone. If the buyer delays an approval, establish how the date will be recalculated. Capacity discussions should expose these dependencies before the purchase order is placed.
Test material readiness separately
Production availability is not material availability. List the critical inputs for the selected product: cabinet substrate and finish, hardware, countertop, basin, glass, driver, lighting, sensor, packaging and printed materials as applicable. Record source status, specification approval, replenishment assumption and required decision date.
Ask which materials are standard stock, order-specific or subject to buyer artwork. Do not assume a component can be substituted to protect schedule. Any change to the approved configuration should follow written impact review and approval.
Include engineering and approval capacity
Large or configured orders can be delayed before production begins. Drawing preparation, sampling, powered testing, artwork and buyer review all consume time. Ask who prepares each submittal and how many revisions the quoted schedule assumes. The buyer should provide realistic response dates and consolidated comments.
Use a milestone plan with dependencies: RFQ clarification, sample order, drawing approval, finish approval, functional sample, artwork, material release, production, inspection, packing and shipment. A single “lead time after deposit” hides the decisions that actually control readiness.
Check quality capacity at the bottleneck
Inspection and rework can constrain good output even when production equipment is available. Ask how many units can be checked using the defined criteria, what equipment or powered stations are required, and how non-conforming items are segregated and reverified. Packaging capacity and finished-goods space can also limit release.
Quality records should connect to order and model codes. A plan based on gross assembly output without allowance for inspection, yield and corrective work is incomplete. For new models, use sample or trial results to refine assumptions before relying on a full-order rate.
Evaluate outsourced and consolidated operations
If countertops, basins, glass processing, finishes or components come from external partners, include their readiness and transport in the schedule. Identify who confirms their capacity and who responds to a late or rejected input. The coordinating supplier should show how incoming conformity and version control are maintained.
For multi-category orders, the slowest component may determine when a complete room set can ship. Review readiness by component and by set. Partial shipment may be possible, but it changes freight, receiving and installation plans and should be a buyer decision.
Ask for a recovery plan, not a guarantee
Identify realistic risks: late approval, material delay, equipment outage, yield loss, subcontractor delay, inspection finding or transport constraint. For each material risk, record early warning, owner, containment and recovery option. Overtime, an alternative component or a second process should not be assumed available without evidence and approval.
Agree how schedule changes will be communicated. A weekly milestone update may be suitable during an active order, with immediate escalation for an event affecting the committed shipping window. The plan should show current forecast, variance, cause and action rather than a generic “on schedule” status.
Validate the plan during order execution
- Approved model and process route match the capacity calculation.
- Production slot and slot-reservation conditions are documented.
- Critical materials have status and release dates.
- Buyer approvals appear as explicit schedule dependencies.
- Quality, rework, packing and outsourced steps are included.
- Progress evidence uses order-level milestones and quantities.
- Risks, variances and recovery actions have named owners.
Request schedule evidence with the quotation
Start with an exact configuration from the ArcQuay product catalogue and provide quantity, destination, approval needs and target shipping window. Review the Foshan sourcing and process overview for planning questions, then include material, milestone and capacity-evidence requests when you submit the RFQ.
