This page teaches what an ERP system, a PLM system, a workflow tool and a spreadsheet are each meant to control, and who uses this to avoid recording the same fact in two places

A single export order passes through several kinds of business system before it ships. An ERP system usually controls commercial and financial transactions. A PLM system usually controls product specifications and their revisions. A workflow tool usually controls tasks, approvals and hand-offs between people. A spreadsheet usually fills a gap none of the others cover yet. Merchandisers, planners, technical staff and buyers all touch these tools, but few of them stop to ask which tool is actually meant to hold which fact.

Without that question, the same order quantity, specification version or approval status can exist in an ERP screen, a PLM record, a workflow ticket and three spreadsheets at once, each one slightly different. This lesson gives you a working test for deciding what each of the four tool types is meant to control, so your own factory, buying office or brand stops duplicating facts that already have a proper home.

03Before you start

What you need, and what this lesson does not cover

You need: a basic understanding of an order, a purchase order, a tech pack and the main factory departments. Course 1 of this track (data ownership and data quality) is useful preparation.

By the end of this lesson you can:

  • name the kind of information each of the four tool types is meant to control;
  • recognise when a spreadsheet is filling a genuine gap and when it is duplicating a system's own record;
  • explain why a workflow tool controls the task, not the underlying commercial or technical fact;
  • point to Order A's own information and say which tool type should hold each piece;
  • avoid recreating the same fact by hand in a second tool "to be safe."

Not covered here: installing, configuring or comparing named software products, database administration, or a full systems-selection process. This lesson stays vendor-neutral and focuses on the business rule, not a specific product.

04Key terms

Words you will meet in this lesson

TermMeaning
ERP systemA business system that usually controls commercial transactions such as purchase orders, inventory, invoices and financial postings.
PLM systemA system that usually controls product specifications, bills of materials and their approved revisions.
Workflow toolA system that usually controls tasks, approvals and hand-offs between people, without being the approved source for the underlying fact.
Spreadsheet gap-fillerA spreadsheet used only for information that no controlled system currently holds.
System of recordThe one system that is the approved, authoritative source for a given type of information.
Duplicate entryTyping the same fact into a second tool that already has, or should have, its own controlled copy.
05Teaching
The rule

Each of the four common tool types is meant to control one kind of business fact, and a spreadsheet should only fill a genuine gap

An ERP system's core job is commercial and financial: the confirmed order, the inventory movement, the invoice, the payment posting. A PLM system's core job is technical: the current approved specification, its bill of materials, and the history of revisions. A workflow tool's core job is procedural: which task is open, who owns it, what stage an approval has reached. None of the three is meant to be the master record for what the other two already control.

A spreadsheet has no fixed job of its own. It is useful exactly where no controlled system yet exists for a fact, and it becomes a problem exactly where it starts holding a second, competing copy of a fact that an ERP or PLM system already owns.

ERP systemPO, inventory, invoicePLM systemSpec, BOM, revisionsWorkflow toolTasks, approvalsSpreadsheetOnly real gapsOne order, one fact each, no duplicate copies
Each tool type controls one kind of fact, and a spreadsheet is meant to cover only what none of the others yet control. Duplicating a fact into a second tool creates two answers to the same question.
What you meet in real life

The tool mix looks different by market, business model and company size, but the ownership rule stays the same

What can differThe shapes you will meetWhy it matters
Export order, Make to OrderAn ERP system holds the confirmed export PO and shipment invoice; a PLM system holds the buyer's approved tech pack; a workflow tool tracks sample approval stages.Nothing here should be re-typed into a private spreadsheet as a second "true" copy.
Domestic order, Make to StockA smaller domestic brand may run its replenishment orders and stock counts entirely inside one ERP module, with no separate PLM system yet.Where no PLM exists, the approved spec must still live in one controlled place, even if that place is a well-managed spreadsheet or document, not a scattered set of copies.
Small factory with no PLM systemSpecifications and revisions are kept in a shared, version-controlled spreadsheet or document because no PLM system has been bought yet.A spreadsheet can be a legitimate temporary system of record if it is controlled the way Course 1 describes; the risk is several uncontrolled copies, not the spreadsheet itself.
Agent or buying office coordinating several factoriesA workflow tool tracks which factory has approved which stage for which order, while each factory's own ERP still owns its own commercial data.The workflow tool coordinates status across companies; it should not try to replace any factory's own commercial or technical system.
Different product familiesSocks and hosiery, knit-to-garment, terry towels and home-textiles orders use the same four tool types, with different fields inside the PLM specification and ERP transaction records.The fields change by product family; which tool type controls which kind of fact does not change.
The case we follow

Northline Apparel places Order A with Delta Garments, and Mona keeps four tools each doing one job

Northline Apparel confirms Order A with Delta Garments: 15,000 T-shirts, single jersey fabric at 180 GSM and Ne 30/1, agreed price USD 3.20 per piece FOB. Mona, the merchandiser, works across an ERP system, a PLM system, a workflow tool and a small set of spreadsheets every day.

The confirmed quantity, the FOB price and the shipment invoice belong in Delta Garments' ERP system, because those are commercial and financial facts. The approved construction, the bill of materials and the size ratio 1:2:2:1 belong in the PLM system, because those are technical specification facts that need a controlled revision history. The stages of sample approval — lab dip sent, buyer comment received, bulk approval given — belong in the workflow tool, because those are tasks and hand-offs, not the specification itself or the commercial value. Mona still keeps one small spreadsheet, but only for a genuine gap: a personal daily checklist of which task is due today, not a second copy of the specification or the PO.

The worked number

Order A's own figures show which system should hold which number

Order A's confirmed quantity and FOB price are commercial facts; the derived fabric requirement is a planning calculation built from a PLM-controlled input.

Confirmed quantity (ERP-held commercial fact): 15,000 pieces
Agreed FOB price (ERP-held commercial fact): USD 3.20 per piece
Order value: 15,000 × 3.20 = USD 48,000
Approved consumption (PLM-held technical fact): 0.205 kg per piece
Fabric requirement (derived from the PLM figure and the ERP quantity): 15,000 × 0.205 = 3,075 kg

The USD 48,000 order value and the 3,075 kg fabric requirement look similar in shape — both are single numbers calculated for the same order — but their approved inputs live in different systems. The quantity and price are ERP-controlled commercial facts. The 0.205 kg consumption figure is a PLM-controlled technical fact. Planning combines both to produce the derived fabric requirement, but planning does not own either input; it only owns the calculation.

GOOD: pull from the system of recordQuantity 15,000 from ERPConsumption 0.205 kg from PLMPlanning calculates 3,075 kgBAD: private spreadsheet copyQuantity re-typed from memoryOld consumption figure reusedResult may not match either system
A calculation is only as reliable as the systems its inputs came from. Copying figures by memory into a private spreadsheet breaks the link to the ERP and PLM records that should control them.
The method

Decide which tool controls a fact in four steps

  1. Ask what kind of fact it is: commercial and financial, technical specification, task and approval status, or something none of your systems currently cover.
  2. Match the kind of fact to the tool type that is meant to control it: ERP for commercial and financial, PLM for specification and revision, workflow tool for task and approval status.
  3. Check whether a controlled system already exists for that kind of fact in your company. If it does, use it as the system of record instead of a spreadsheet.
  4. Reserve a spreadsheet for a genuine gap only, and mark clearly that it is not the approved source once a proper system starts covering that fact.
The trap

A common mistake is keeping a personal spreadsheet "just in case" that quietly becomes a second, competing copy of an ERP or PLM fact

A merchandiser under time pressure often builds a personal tracking sheet with the order quantity, price and specification copied in for convenience. That sheet is fast to open and easy to edit, so it starts being trusted more than the ERP or PLM screen it copied from. When the buyer later changes the quantity, the ERP system is updated, but the personal spreadsheet is not, and the two numbers quietly disagree. The cost is not the spreadsheet itself; the cost is treating a convenience copy as if it were a system of record.

06In plain words

Think of four tools with four separate jobs. One tool keeps track of money and quantities that were agreed. One tool keeps track of what the product must be, and how that changed over time. One tool keeps track of who still needs to do something and whether it is done. A spreadsheet is a helper you use only when none of the other three yet cover something you need to record.

The mistake most people make is copying a fact from one of the first three tools into a spreadsheet "to keep an eye on it," and then trusting the spreadsheet more than the tool that actually controls the fact. Once you know which of the four tools is meant to hold a fact, you stop needing a private copy of it.

07Quick check
  • An ERP system is normally the system of record for confirmed commercial quantities, prices and financial postings.
  • A PLM system is normally the system of record for approved product specifications, bills of materials and revisions.
  • A workflow tool tracks tasks, approvals and hand-offs; it is not the source of the underlying commercial or technical fact.
  • A spreadsheet is legitimate only where no controlled system yet exists for that kind of fact.
  • A convenience copy of a fact in a spreadsheet should never be trusted over the system that actually controls it.
  • The four tool types stay the same across export, domestic, Make to Order and Make to Stock orders; only the fields inside them change.
08Workplace scenario

Mona notices her personal tracking sheet still shows the old Order A quantity a week after Northline Apparel confirmed a change through the approved purchase-order amendment

Mona built a personal spreadsheet early in Order A to keep a daily view of tasks and figures in one place. The approved amendment changing a downstream planning figure was entered into Delta Garments' ERP system on the day it was confirmed. Mona's personal spreadsheet, however, still shows the earlier value, because she has been busy and has not opened that tab in several days. A colleague in planning asks her which number is correct before finalising a material booking.

Which figure should Mona tell her colleague to use, and what should she do with her personal spreadsheet? Decide before opening the answer.

Show decision

The ERP system's current record is correct; Mona's personal spreadsheet must be corrected or retired, not treated as a second source.

1. Mona confirms the current approved figure directly from the ERP system, since that is the system of record for a confirmed commercial change. 2. She tells her colleague to use the ERP figure for the material booking, not the older figure sitting in her personal sheet. 3. She updates or deletes the stale line in her personal spreadsheet so it cannot mislead her or anyone else again, and reminds herself the sheet is a convenience view, not an approved source. 4. If she needs a daily task view, she rebuilds it to pull the current figure from the ERP system each time, rather than typing a number once and letting it go stale.

The material booking should never be based on a spreadsheet that copied a figure from the system of record and then fell out of date.

09What it costs

A stale spreadsheet copy can lead to a material booking that does not match the approved order

Order A's confirmed value is directly derived from its fixed quantity and price:

15,000 pieces × USD 3.20 per piece = USD 48,000 total FOB value

If planning had booked material against Mona's stale spreadsheet figure instead of the ERP system's current record, the fabric requirement calculated from it would not match the order actually confirmed with Northline Apparel. Re-ordering, re-booking or holding excess material wastes time and, depending on the size of the gap, real money against an order worth USD 48,000. The cost of checking the system of record before finalising a booking is a few minutes; the cost of not checking is measured in wasted material, wasted time, or a late shipment.

Business-system role map: record which tool controls each kind of fact on your own orders

Use the T17-C02 Business-system role map workbook. For each important fact on an order, record what kind of information it is, which tool type is meant to control it, whether a controlled system currently exists for it in your company, and whether any spreadsheet copy of it should be retired. Start with Order A, then repeat the exercise for one order you handle yourself.

11Check yourself

1. For Order A, which tool type should normally control the confirmed quantity and agreed FOB price?

2. A small factory has no PLM system yet and keeps its approved specifications in a shared, version-controlled document. Is this acceptable?

3. Why should a workflow tool tracking sample-approval stages not also be treated as the source of the approved specification?
