Lessons 4.1 to 4.4 each taught one piece of a warehouse's own inventory control decision: what a WMS actually replaces, whether barcoding or RFID fits, what a rollout really costs, and how a cycle count changes under a WMS. A domestic brand such as Cedar & Co., running 12 shops on a mostly Make to Stock model with one Make to Order capsule collection through Delta Garments, needs all four pieces working together on one operation, not as four separate exercises.
This lesson walks through Cedar & Co.'s own central warehouse using the complete worksheet, so you finish this course able to run the same four checks on any warehouse you are responsible for.
You need: Lessons 4.1 through 4.4 of this course, ideally in order, though the worksheet itself can be used without having read all four.
By the end of this lesson you can:
Not covered here: any new calculation method; this lesson only assembles the four methods already taught in Lessons 4.1 to 4.4.
| Term | Meaning |
|---|---|
| Recording gap | The delay between a warehouse event happening and its record becoming trusted, closed by a WMS and left open by a paper process. |
| Technology fit | Whether barcoding or RFID matches a specific operation's own carton mix, pallet handling and margin, per Lesson 4.2's method. |
| Payback period | The time it takes for a machine's total monthly savings to add up to its total investment cost. |
| Inventory accuracy rate | The physical count divided by the book stock, shown as a percentage, measuring how closely the system matches reality. |
| Combined inventory control check | Reading all four of the worksheet's own sheets together for one operation, rather than treating each as an isolated exercise. |
A warehouse that closes its own recording gap with a WMS, but chooses a technology that does not fit its own carton mix, still wastes money on the wrong per-unit tag cost. A warehouse that chooses the right technology, but never checks the rollout's own payback period, can commit budget without knowing when it pays back. A warehouse that gets both right, but never verifies its own cycle count results with an occasional spot-check, can carry a wrong accuracy figure into other decisions. The four checks depend on each other; reading only one gives a false sense of completeness.
| What can differ | The shapes you meet | Why it matters to you |
|---|---|---|
| Starting point | A warehouse still fully on paper, like Cedar & Co.'s own central warehouse before this course, starts with Lesson 4.1's recording-gap question; a warehouse already running a WMS starts with Lesson 4.2's technology fit instead. | Running the checks in the wrong order for a business's own starting point wastes effort on a decision that is not yet relevant. |
| Business model | Cedar & Co.'s own hybrid model, mostly Make to Stock with one Make to Order capsule, needs the technology-fit check applied separately to each part, since a capsule's own smaller, more varied cartons behave differently from core replenishment stock. | A single technology decision applied uniformly across a hybrid account can fit one part of the business well and the other part poorly. |
| Available budget | A business with an approved rollout budget moves straight to Lesson 4.3's payback calculation; one still building a case for budget uses the same calculation to justify the request instead. | The same calculation serves two different purposes depending on whether budget is already available or still being requested. |
| Maturity of existing counting practice | A warehouse with an established, disciplined paper cycle count schedule gains less from Lesson 4.4's WMS-guided rotation than one whose paper rotation regularly misses locations. | The size of the benefit from a WMS-guided count depends on how well the paper process it replaces was actually being run. |
Cedar & Co. operates 12 shops on a mostly Make to Stock model, buying core replenishment from Delta Garments on a 60-day open account, and recently added one small Make to Order capsule collection produced through the same factory relationship. Before committing to a second capsule, Cedar & Co.'s own management wants one combined check: is the warehouse's recording gap worth closing, does barcoding or RFID fit the mixed core-and-capsule carton flow, what would a rollout actually cost against its own saving, and how would cycle counting change under a WMS.
Running all four sheets together, rather than one at a time, lets Cedar & Co.'s management see the full picture before approving budget for the expansion.
The worked numberNo single sheet alone would have produced this combined recommendation; Sheet 2's own split answer, barcoding for core stock but RFID for the capsule, only becomes visible when the technology-fit check is applied separately to each part of a hybrid account, exactly as the table above sets out.
A business asked to approve a rollout budget often jumps straight to the payback-period sheet and stops there, without checking whether the chosen technology actually fits the operation's own carton mix, or whether the warehouse's own recording gap was worth closing in the first place. A payback period calculated on the wrong technology choice is still the wrong number, however carefully the arithmetic itself was done, which is why this course's own final worksheet links all four sheets rather than leaving them as separate tools.
This course taught four separate things: what a computer system actually changes about tracking stock, which technology, barcode or RFID, fits a specific warehouse, what a new system really costs against what it saves, and how a stock count changes once a computer runs it. None of those four questions gives the full picture on its own. The complete worksheet holds all four together, so a business can look at one warehouse and see the whole decision at once, not four separate answers that might even disagree with each other.
Cedar & Co.'s management is under pressure to approve the second capsule collection quickly, to meet a buyer's own seasonal deadline.
Should Cedar & Co. approve the second capsule now, based on the two completed checks, or wait for all four to finish? Decide before opening the answer.
Wait for the technology-fit check specifically, though the cycle count data can continue collecting in parallel.
1. The technology-fit check is the one most likely to change the actual decision, since Lesson 4.2's method shows a capsule's mixed, more varied cartons can favour a different technology from core stock, and approving a rollout before checking this risks buying the wrong technology for the new capsule specifically. 2. The cycle count sheet's incomplete data does not block the capsule decision, since accuracy-rate evidence accumulates over time regardless of whether the capsule is approved now or later, and one week's data was never going to be enough either way. 3. Approving the capsule on two completed checks while skipping the technology-fit check treats a partial result as a complete one, exactly the trap this lesson identifies.
The buyer's own deadline pressure is real, but running the technology-fit check takes a matter of days, not months, and skipping it risks a wrong technology choice that costs far more than the short delay.
USD 18 looks small against a seasonal capsule's total value, but it recurs on every future capsule if the skipped technology-fit check becomes standard practice under deadline pressure, which is exactly why the method in this lesson insists on running all four checks together rather than only the one under immediate pressure.

1. Why does a complete inventory control decision need all four of this course's checks read together, rather than one in isolation?
2. Cedar & Co.'s core replenishment stock favours barcoding, but its new capsule's mixed cartons favour RFID. What does this show about applying a technology-fit check to a hybrid account?
3. A business has completed the recording-gap and rollout-cost checks but not technology-fit or cycle count, and is under deadline pressure. What should it do?
