# Build readiness

> mBOM readiness and shortages, as-built installation progress, and plan fulfillment across supply statuses.

In ION, go to **Analytics > Build Readiness**. The surface has three sub-tabs: **mBOM**, **aBOM**, and **Plans**. Use it to answer: can I build this assembly today, what is short and what does the shortage cost, how far along is each as-built unit, and how fulfilled is each plan.

Each detail table has an **Export** control that exports the table, with its current filters applied, to CSV.

## mBOM

The default sub-tab measures whether stock covers each assembly's mBOM. Filter by top-level **Part Number**, **Rev**, and **Rev Match** (All, Match, or Cross-Rev) to control whether inventory at a different revision counts toward readiness.

* KPI cards: **Average Readiness**, **Short Parts**, **Shortage Cost**, **Ready to Build** (assemblies at 100% readiness), and **Max Builds**.
* **Part Fulfillment**: components bucketed as No Stock, Short, or Fulfilled.
* **Top Shortage Parts**: the parts with the highest shortage quantities.
* **mBOM Readiness Detail**: a table grouped by assembly tree, with columns including **Part**, **BOM Rev**, **Inv Rev**, **Rev Match**, **Qty Required**, **Qty Available**, **Qty On Order**, **Shortage**, **Shortage Cost**, **Readiness**, and **Max Builds**, plus expandable **Procedures** and **Suppliers** details per part.

## aBOM

Tracks installation progress and cost on as-built assemblies. Filter by **Part Number**, **Rev**, and **Serial**, and toggle **Hide root nodes** to drop top-level rows from the tree.

* KPI cards: **Total Cost**, **Total Parts**, **Fully Installed**, and **Open Issues**.
* **Installation Status**: installed versus not installed parts.
* **Parts by Level**: part counts across BOM levels.
* **aBOM Detail**: a table grouped by assembly tree, with columns including **Required Part**, **Installed Part**, **Req Qty**, **Installed Qty**, **Installed**, **Unit Cost**, **Total Cost**, **Open Issues**, and expandable **Linked Runs** and **Linked POs** details.

An **Issues** view within this sub-tab lists only the parts that carry issues, so you can see quality blockers on the build without leaving the tree.

## Plans

Measures fulfillment per plan. Pick a plan from the **Plan** selector or view all plans at once.

* KPI cards: **Overall Fulfillment**, **Plans**, **On Hand**, **WIP**, **On Order**, and **Planned** (quantity that still needs a PO or run).
* **Overall Status Distribution**: quantities by supply status.
* **Status by Plan**: the fulfillment breakdown per plan as stacked percentages.
* **Build Status Detail**: a table with columns including **Plan**, **Part**, **Sourcing**, **Total Qty**, **On Hand**, **WIP**, **On Order**, **Planned**, **Fulfilled**, and **PO Supplier**.
