# Clear to Build: Definition, Formula and Dashboard

> Clear to build (CTB) is the check that every component, revision and resource a build needs is available, and the CTB quantity is how many units you can make before the scarcest part runs out. A clear-to-build dashboard shows that number per work order, explains each blocker and names who resolves it, while the ERP stays the record owner.

## What is clear to build?

**Clear to build (CTB) means a planned build has everything it needs to start: every component on the bill of materials in usable quantity, and in most plants the released revision, equipment and people as well.** Planners also use clear to build as a number: the quantity of finished units you can make before the first component runs short. That scarcest component is called the gating item, and it sets the whole answer.

A planner in [an r/supplychain thread on clear to build reports](https://www.reddit.com/r/supplychain/comments/xzr66d/clear_to_build_and_what_a_clear_to_build_report/) gave the cleanest version of it: if you plan to build phones at a million a day but the antenna supplier is only ramped to 900,000, "we are clear to build 900k per day, and antennas are top gate." Another planner in the same thread described the clear to build report as the final list of planned orders production can actually manufacture, usually the frozen period plus a few days, built on one rule: never send an order to the floor if a component is missing or engineering is not ready.

The term is most common in high-tech and electronics supply chains. Apple, Amazon and Tesla job listings all ask materials and supply managers to run [Clear-to-Build (CTB) management](https://jobs.apple.com/en-il/details/200671455-0157/materials-program-manager), which is why people meet the phrase in a job posting before they meet it on a report. The concept applies to any shop that assembles parts it buys in, from a panel builder to a machine shop running kits.

## How clear to build is calculated

**For each component, divide the usable quantity available to this build by the quantity each finished unit needs, then take the lowest result.** That minimum is your clear-to-build quantity, and the component that produced it is the gating item.

SourceDay's [clear to build explainer](https://sourceday.com/blog/clear-to-build-and-your-supply-chain-what-you-need-to-know/) works one through: a plan for 500 units, each needing one motor, one control board and two brackets. The plant has 500 motors and 1,000 brackets but only 420 control boards confirmed before the production date, so it is clear to build 420. Brackets look like a bigger number on the stock report and still do not matter, because 1,000 divided by two per unit is exactly 500.

| Component | Needed per unit | Usable for this build | Units it supports |
| --- | --- | --- | --- |
| Motor | 1 | 500 | 500 |
| Control board | 1 | 420 | **420 (gating item)** |
| Bracket | 2 | 1,000 | 500 |

Two refinements make the number honest:

- **Separate on-hand CTB from CTB with inbound supply.** As Kaizoft explains in its [Clear To Build product walkthrough](https://www.youtube.com/watch?v=vLXkGx3ZI9Y), the same screen can show enough parts in stock "to build seven units" today and 50 units once confirmed deliveries land. Both numbers are useful; mixing them is how a plan looks feasible and a line sits idle.
- **Count usable, allocated stock, not the raw balance.** Quantity on quality hold, reserved for another order or sitting at the wrong revision should not count. The allocation example further down shows how two orders can each look clear against the same shelf.

Run the calculation per period, not once. A weekly CTB table that carries leftover inventory forward and adds receipts in the week they arrive shows which week goes negative, which is the week to call the supplier about a partial delivery.

## Clear to build vs MRP vs available to promise

**MRP decides what to order and when, available to promise (ATP) decides what you can commit to a customer, and clear to build decides whether a specific build can start with the supply that actually exists.** They use the same inputs and answer different questions.

| Concept | The question it answers | Who usually owns it |
| --- | --- | --- |
| MRP | What materials do we need, when, and what should we order? | Materials planning and purchasing |
| Available to promise | How many can we promise a customer by this date? | Sales and customer service |
| Clear to build | Can this build start now, and how many units? | Production planning, at the release meeting |

MRP runs on planned lead times and assumes open purchase orders arrive as dated. Clear to build is where that assumption gets tested against what suppliers confirmed, what receiving counted and what quality released. A planner in the r/supplychain thread was blunt that it is "basically forecasting" under a tech-industry name, and that is fair: the difference is the horizon. CTB looks at the frozen period and the next few days, where a wrong answer costs a stopped line rather than a reorder.

## What a clear-to-build dashboard should answer

A manufacturing clear-to-build dashboard should answer a specific question: **can this work order start, in this planned window, with the resources and instructions it actually requires?** A useful answer includes the blocker, the evidence behind it, and the person who can resolve it. A green tile showing that several applications are online does not answer that question.

The opportunity is a [production-readiness workspace](https://www.pavadotech.com/blog/field-service-job-readiness-checklist) connecting the systems a plant already uses. It can combine ERP work orders, inventory reservations, quality holds, maintenance restrictions, and document revisions. It should expose disagreements without quietly becoming a competing inventory ledger or an unofficial machine-release system.

Start with one line, product family, or release meeting. The difficult work is usually agreeing what counts as ready and [which record wins](https://www.pavadotech.com/blog/crm-that-syncs-with-quickbooks-two-way) when systems disagree.

## Why another manufacturing dashboard can become another problem

In [a manufacturing discussion about software overload](https://www.reddit.com/r/manufacturing/comments/1uaib2x/tired_of_drowning_in_softwares/), the author described overlapping maintenance, quality, safety, training, and connected-worker applications. Their complaint was repeated information and difficulty locating a trustworthy record. This is one person's account across their workplaces, not a measured industry failure rate.

The comments sharpen the problem. One commenter joked that unifying fourteen tools produces a fifteenth. Another described a collection of scheduling tools and calendars while [the master job list](https://www.pavadotech.com/blog/job-tracking-app-for-small-contractors) remained on a whiteboard. A third argued that changing one component is easier than replacing the whole business system.

Those responses suggest a useful buying criterion: a new workspace must retire a specific reconciliation task. If planners still [rebuild the same spreadsheet](https://www.pavadotech.com/blog/how-to-move-from-spreadsheets-to-a-crm) before trusting the dashboard, the project has moved the work rather than removed it. The whiteboard may be an effective coordination surface; investigate what people can express there that the current software misses.

## Define readiness at the work-order level

“Ready” is conditional. An order can have enough material in the building but lack an approved substitute, a released drawing, a fixture, or a qualified operator for the intended shift. A dashboard should express the conditions relevant to the selected operation instead of calculating an unexplained universal score.

There is a useful standards vocabulary for this. The [OPC Foundation's ISA-95 overview](https://opcfoundation.org/markets-collaboration/isa-95/) describes information exchange between manufacturing operations and enterprise systems, including equipment, personnel, physical assets, and materials. Its [job-control specification](https://reference.opcfoundation.org/specs/OPC-10031-4/4) describes job orders and their resource requirements. These references help name the entities; they do not make a particular plant's data accurate or certify a custom dashboard.

Write a readiness contract with the production team. Identify the operation being evaluated, the planned time window, the required evidence, the permitted age of each input, and the role allowed to approve an exception. Keep this contract readable enough to use during a release meeting.

| Readiness question | Evidence to inspect | Possible blocker owner |
| --- | --- | --- |
| Is the required material allocated? | Item, location, usable quantity, reservations | Materials planner |
| Is the instruction current? | Approved revision tied to this operation | Engineering |
| Can the equipment be used? | Scheduled availability and relevant holds | Production or maintenance |
| Is the material released? | Lot identity and quality disposition | Quality |
| Are special resources available? | Fixture, tooling, skill or shift assignment | Production supervisor |

This table is a proposed starting point. A plant should remove irrelevant checks and add the constraints that actually stop its work.

## Inventory availability needs allocation, not just arithmetic

A common design mistake is evaluating every order independently against the same stock balance. Consider a hypothetical cell with ten usable units of component A. Order 101 needs eight units and order 102 needs six. Each order appears feasible if checked alone. Together they require fourteen units.

If the planner allocates eight units to order 101, only two remain available for order 102. The dashboard should show the second order short by four units under that allocation. Reprioritizing the orders changes the answer; it does not create more inventory. Preserve the allocation decision and its time so another planner can understand why yesterday's answer differs from today's.

Keep on-hand, usable, reserved, expected, and physically confirmed quantities separate. An expected receipt can support a future plan without proving material is ready now. A received lot on hold should not be counted as usable merely because it appears in an inventory balance.

Also define units of measure. A conversion between pieces, packs, length, and weight needs an approved rule associated with the item. A silent unit conversion error can make a mathematically correct readiness check operationally wrong.

## The missing clamping rings: distinguish counting from event capture

In [a production planner's account of ERP availability versus the floor](https://www.reddit.com/r/manufacturing/comments/1t8bgjm/i_actually_do_this_for_living/), an assembly order appeared fully supplied until the supervisor discovered three missing clamping rings. The author said another shift had used them for a rush dispatch without updating the system. They estimated that 30% of their own work involved planning and system management, with 70% spent checking the floor and maintaining workarounds. That is a personal estimate, not a manufacturing labour study.

The comments describe different remedies. Two commenters discuss regular stock checks. Another argues that counting alone leaves the reason people take allocated parts unresolved. A fourth describes physically separating inventory and requiring requisitions, while acknowledging production delays as a tradeoff. Their claimed accuracy results are not independently verified benchmarks.

For a readiness project, ask which missing event created the wrong answer. If a kit was reassigned without a transaction, another dashboard refresh cannot recover that unrecorded action. A count can reveal the discrepancy; a workable issue, transfer, or exception process is needed to keep the next shift from inheriting the same problem.

Keep these projects connected but distinct. The readiness view explains whether an order can proceed from available evidence. A [shop-floor capture workflow](https://www.pavadotech.com/blog/replace-excel-shop-floor-tracking) records the material movements and operation results that supply that evidence. Test both the physical handoff and the record update when parts move between jobs.

## Resolve disagreements without erasing their history

Suppose the ERP places a pallet in location B, but a supervisor reports that it is still at the receiving dock. The workspace should display a location discrepancy and link to the records. It should not select whichever value arrived most recently and present it as physical truth.

[Assign record ownership](https://www.pavadotech.com/blog/quickbooks-crm-sync-problems) before integration. The ERP might own stock transactions, engineering might own released revisions, and a quality application might own lot disposition. The readiness workspace can own the derived blocker and the workflow for investigating it. That separation makes corrections understandable.

For each source, record an identifier, source update time, ingestion time, and the relevant revision or version. Ingestion time means the integration observed something then; it does not prove the underlying fact was updated then. This distinction matters when an export refreshes successfully while its source records remain old.

A reviewer should be able to move from “blocked: material location uncertain” to the source evidence in a few steps. If resolving a discrepancy requires searching five applications from scratch, the integration has not delivered its central benefit.

## Make unknown a first-class state

Use at least three states: ready, blocked, and unknown. Ready means the agreed conditions have supporting evidence. Blocked means a known condition is not satisfied. Unknown means the evidence is missing, stale, inaccessible, or ambiguous.

Do not treat an empty maintenance response as proof that equipment has no restrictions. It could indicate a permissions problem, an incorrect asset mapping, or a failed query. Likewise, a drawing with no approval field is not necessarily approved. The workspace should identify which uncertainty prevents the readiness decision.

Freshness should vary by decision. A periodically maintained skill record and a rapidly changing material reservation do not need the same refresh policy. Ask the operational owner how old an input can become before relying on it would be misleading. Show that policy alongside the observed age when it causes an exception.

An unknown state will initially make the dashboard look less impressive. That is useful information: the plant can see where its release process currently depends on phone calls, memory, or assumptions.

## Design the morning release meeting around actions

A readiness screen should help participants make the next decision. Group blockers by order and owner, show the planned start, and distinguish an issue that can be resolved now from one waiting on an external event. Avoid filling the main view with every available machine metric.

For a material shortage, show the required quantity, current allocation, expected receipt if known, and any proposed substitute awaiting approval. For an instruction problem, show the required revision and the conflicting document. For an equipment restriction, show the applicable source record and responsible team without paraphrasing away its conditions.

Allow the team to record a next action and due time. “Buyer checking receipt date” is more useful than a generic amber status. When the next action changes, retain the earlier history so recurring problems can be investigated later.

Do not automatically release work orders in the first version. Let the authorized planner confirm the decision in the established system. A later write-back phase can be considered after the team has tested how the workspace handles updates, reversals, and simultaneous changes.

## Choose the smallest useful technical approach

A scheduled export and [a modest database](https://www.pavadotech.com/blog/how-to-build-a-custom-crm-for-a-small-business) may be sufficient when the decision is made once per shift. An API integration may be appropriate when reservations change frequently. Barcode confirmation could be more valuable than an AI assistant if the real gap is identifying which pallet moved.

Evaluate the access available in the actual software edition and deployment. Ask for supported interfaces, export completeness, identifiers, update behavior, and [vendor support expectations](https://www.pavadotech.com/blog/what-happens-to-my-data-if-my-software-shuts-down). A product logo on an architecture slide is not proof that the needed field can be read or changed.

Use a read-only start where practical. Store only the data needed to explain readiness, and keep clear links to the authoritative records. If a source cannot provide changes incrementally, plan how a full refresh detects deleted or superseded records without reviving them.

AI can help [classify an incoming document](https://www.pavadotech.com/blog/invoice-ocr-validation-checklist) or draft a plain-language explanation of a known blocker. Quantity allocation, revision comparison, and permission checks should have explicit rules. Our [AI agent versus workflow automation guide](https://www.pavadotech.com/blog/ai-agent-vs-workflow-automation) explains how to separate tasks that need judgment from predictable system steps.

## Test the uncomfortable cases before expanding

Create a small evaluation set from permitted historical work orders. Include straightforward jobs, shortages, revision changes, quality holds, and missing identifiers. Have production staff label what the correct readiness result would have been at the decision time, using the evidence available then.

Test a late receipt that arrives after the planned start. Test an order whose priority changes after material is allocated. Test a quantity reduction, a cancelled order, a partial completion, and a source outage. A system that only handles clean new orders will disappoint precisely when coordination matters most.

For each case, inspect both the displayed result and the explanation. A correct blocked status with the wrong reason still wastes the planner's time. A green status based on stale data should be counted as an incorrect readiness decision even if the job happened to run successfully.

Include one deliberately ambiguous case. The expected result should be unknown with a sensible owner, not a confident guess. This is a practical way to test whether the workspace respects the readiness contract instead of optimizing for a tidy screen.

## Assign ownership when the shift changes

A blocker can survive several shifts, so its next action should belong to a role or assigned person with a clear handoff. Record who is covering an absent owner and whether the expected resolution time has changed. Otherwise the dashboard can display the right issue while everybody assumes another team is handling it.

Keep operational overrides visible. If an authorized planner proceeds under an approved exception, record the decision, reason, and scope without changing the underlying evidence to make the job appear fully ready. A later reviewer should be able to distinguish a deliberate exception from a missed check. This history also helps identify requirements that need a clearer rule or a better source.

## Measure the decision, not dashboard activity

Record the time spent assembling the release view, investigating discrepancies, and correcting wrong results. Track how often released jobs encounter a blocker the workspace was supposed to detect. Also record false blockers: unnecessary holds can be costly even when they make the system appear cautious.

Use comparable work and disclose the scope of the comparison internally. A pilot on repetitive orders should not be presented as proof for every product family. Separate changes caused by the integration from changes in staffing, demand, supplier reliability, or the production plan.

Review whether a manual artifact can actually be retired. The best sign may be that the planner stops maintaining a parallel material-check spreadsheet because the workspace now exposes the evidence they need. If the spreadsheet remains necessary, ask which decision or exception it handles better.

Do not promise a percentage productivity gain before measuring the baseline. The initial deliverable can be a clearer release decision and a visible list of data-quality gaps; [the financial case](https://www.pavadotech.com/blog/custom-crm-development-cost) should follow observed use.

## Scope a production-readiness build with Pavado

Pavado can help scope a custom production-readiness workspace around the plant's existing tools. The proposed offering is a focused integration and decision interface, with optional barcode capture, document checks, and operational reporting where they solve a demonstrated problem. It is not a claim that a prebuilt connector exists for every ERP or machine.

Bring one representative work order, a redacted release checklist, the systems involved, and an example of a recent blocker discovered too late. The first useful output is a map of required evidence, record owners, integration access, and acceptance cases. That makes the project concrete before selecting a dashboard framework or language model.

Use the manufacturing review form on this page to describe the line or process and what currently prevents a reliable release decision. The right first build should make one production meeting simpler and one class of readiness mistake easier to catch.

## FAQ

### What does clear to build mean?

Clear to build means a planned build has everything it needs to start: the components on the bill of materials in usable quantity, plus whatever else your plant requires, such as a released revision or an available fixture. Planners also use it as a number, the quantity of finished units you can make before the first component runs short.

### How is clear to build calculated?

For each component, divide the usable quantity available for this build by the quantity needed per finished unit, then take the lowest result. That lowest component is the gating item and sets the CTB quantity. Use allocated, released stock rather than the raw on-hand balance, and run it twice if you want an on-hand figure and a figure that includes confirmed inbound receipts.

### What is a clear to build report?

A clear to build report lists planned orders or assemblies with each component line, the quantity required, the quantity available and the shortfall, then marks each order as clear or not. Planners usually run it for the frozen period of the schedule plus a few days, so production only receives orders it can actually complete.

### What is the difference between clear to build and MRP?

MRP works out what to order and when, based on demand, the bill of materials, inventory and lead times. Clear to build checks whether a specific build can actually start now with the supply that exists or is confirmed. MRP creates the plan; CTB tests whether the plan is executable this week.

### Does a clear-to-build dashboard replace an ERP?

It does not have to. It can read work orders and supporting evidence from existing systems while leaving transactions and approvals in those systems.

### Can available stock make two jobs look ready?

Yes, if readiness checks do not account for allocation. The same units must not be promised to multiple jobs at once.

### Should missing data show as ready?

No. Use an explicit unknown state with the missing source and responsible owner. A successful data refresh does not prove that every required fact exists.

### Do we need AI for production readiness?

Many checks are deterministic comparisons. AI may help extract information from documents or explain a blocker, but it should not invent inventory or release authority.
