*Part 4 of 18 · Before the Shelf*

## The machine arrived. The books still cannot be made

Mayan has delivered a printing machine from Sapiens Inc to Maya at Stories Inc. Maya also has an order for 1,000 books. It is tempting to join those facts and call the order feasible.

But equipment at the gate is not productive capacity. In our teaching scenario, Maya must have the site ready, arrange suitable installation, complete commissioning checks and establish the agreed acceptance evidence. She also needs paper, covers, binding materials and packaging from separate suppliers, plus people, production time and quality release.

This is why sourcing begins with the capability the business needs. eComm Inc can buy a finished book for resale. Maya has to bring several inputs and a working process together to produce one.

## Independent demand becomes dependent requirements

Demand for the finished book is the starting requirement. The **bill of materials**, or BOM, states the components needed to make it. **Material requirements planning**, or MRP, works backward through quantities, available stock, scheduled receipts and timing. [MIT's public MRP](https://www.ocw.mit.edu/courses/2-854-introduction-to-manufacturing-systems-fall-2016/4eec617bb52d64f4ea1bed6d9905bc00%5FMIT2%5F854F16%5FMatrialRequire.pdf?ref=abundance.alloconomy.com) teaching materials explain this foundation; our miniature example is deliberately simpler than a working factory.

Assume each finished book needs one standardized paper kit, one cover set and one binding set. A target of 1,000 good books requires 1,000 good kits of each. If the entire production process has an assumed 95% yield, the gross starting quantity is:

**1,000 ÷ 0.95 = 1,052.63, rounded up to 1,053 complete sets.**

This assumes a predictable complete-process yield and that components are consumed together. If 95% is only an expected yield, starting 1,053 sets does not guarantee 1,000 good books in a particular run. Real scrap can occur at different stages, so each component may need its own yield and recovery logic. The arithmetic explains a planning assumption; it does not establish a production service guarantee.

[![An exploded material bill joins one paper kit, one cover set and one binding set into each complete starting set. At an assumed 95 percent complete-process yield, 1,053 starting sets support an expected 1,000-good-book target calculation. The printing machine supplied by Sapiens Inc enables production and is not consumed per book. Yield is an illustrative planning assumption, not a guarantee.](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/before-the-shelf/figures/part-04.png)](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/before-the-shelf/figures/part-04.png?ref=abundance.alloconomy.com)

Make the whole book feasible. ceil(1,000 ÷ 0.95) = 1,053 complete starting sets. All examples are fictional and indicative; analyze real operations case by case.

## Time the inputs to the work

If printing needs two days, binding one day, inspection one day and outbound preparation one day, Maya needs five sequential working days after all required inputs become usable. A Friday paper arrival does not imply Friday production readiness if the paper needs inspection or the plant is closed for the weekend.

The **critical path** is the chain of dependencies that determines the earliest feasible completion. More paper cannot fix a missing cover set. Expediting a noncritical component may spend money without moving the completion date.

Lot sizes and minimum order quantities complicate the plan. A paper supplier may sell only full pallets; Maya may prefer small frequent deliveries. A low unit price for a large lot must be weighed against storage, cash and the risk of changing demand. A capacity reservation is another possible commitment: it can protect production time, but unused reserved capacity still has commercial consequences.

## What must actually be sourced?

| Sourcing layer           | What Maya needs to establish                                                                              |
| ------------------------ | --------------------------------------------------------------------------------------------------------- |
| Goods and specifications | Correct edition, paper quality, dimensions, allowed substitutions and tolerances                          |
| Supplier capability      | Capacity, demonstrated quality, lead-time range, financial and operational resilience                     |
| Productive equipment     | Suitable printing machinery, site readiness, installation, commissioning, acceptance evidence and support |
| Logistics services       | Suitable equipment, lanes, handling, storage, appointments and recovery support                           |
| Information              | Product and pack data, lot identity, shipment notices, event access and correction process                |
| Compliance evidence      | Origin, product requirements and any applicable safety or environmental documentation                     |
| Accountability           | Named owners for changes, disputes, escalation and emergency decisions                                    |

This is a proposed sourcing checklist, not a claim that every buyer uses an identical process. Its purpose is to uncover dependencies before a low price creates a fragile promise.

[![Source goods, capacity, data, continuity and accountability.](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/before-the-shelf/figures/sourcing-checklist.png)](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/before-the-shelf/figures/sourcing-checklist.png?ref=abundance.alloconomy.com)

Source goods, capacity, data, continuity and accountability. Public concepts; fictional scenario. Actual operations require case-by-case analysis.

## Equipment has a different completion test

Mayan supplies a machine that can support many future production runs. A paper kit is consumed in making a book. Putting both purchases under the label “inputs” must not erase that difference.

For the machine, Maya needs an agreed path from dispatch to delivery, installation, commissioning and acceptance. In this scenario, commissioning means checking the installed machine against agreed operating requirements; acceptance records the parties' agreed contractual milestone. Neither should be inferred from the carrier's delivery signature. The actual tests, responsibilities and technical requirements belong in the equipment agreement and qualified installation plan.

For paper and covers, the recurring questions are quantity, specification, release and arrival before the production step needs them. A changed paper mill or pack size may require different checks even if the purchase price is unchanged. A changed machine configuration may require different site preparation, training or spare parts.

## Ask for a demonstration of the whole promise

Mayan's sophistication may help Maya plan the installation and support the equipment. It does not remove the need for evidence. Maya can ask what the acceptance demonstration will show, who handles a failed check, what support is available and which dependencies could delay recovery. A materials supplier can demonstrate a representative shipment, accurate packing and a controlled response to a discrepancy. Across either relationship, examine the range of actual lead times rather than only the average, and identify shared upstream dependencies that could defeat the backup plan.

Now return to the 1,000-book order. If covers arrive three days after paper, paying to move the paper faster helps only if paper is on the path that determines completion. If the printing machine has not been accepted for use, both sets of materials may simply wait. Compare feasible completion dates before comparing freight premiums.

That is the buying decision this chapter is meant to improve: source everything needed to make the promised output possible, and identify which missing capability would stop it.
