What a finished AC557 Unit 4 process walkthrough looks like
A walkthrough memo of five pages with a marked-up copy of the process narrative on file. The memo names the transaction, identifies the narrative it tests and states the purpose: to confirm, for management's own assessment, that the purchase cycle and its controls operate as documented. Seven steps follow in order, gate and seller identification, weigh-in, grading, unloading, weigh-out, pricing and ticket, and kiosk payment, each recorded with the procedure used, the person observed or asked, the record inspected and the result. At grading, the photo in the ticket file shows copper on the ground, not in the truck bed. At payment, one clerk had loaded the kiosk alone. A closing page lists three findings and the controls confirmed as operating.
How a AC557 Unit 4 example is structured
Each step appears in the order the metal moves, with the narrative's own wording quoted beside each one so a reader sees the claim and the observation together. Every step uses more than inquiry: the weigh-in was observed, the ticket inspected, and the price recomputed from that morning's price table, 2,400 pounds at the posted number two rate. Findings are classified before they are explained. The photo timing is a design gap, since even a perfectly taken ground photo cannot show what arrived in that truck. The single-person kiosk load is also a design gap, a custody weakness no diligence would fix. Free-text override reasons such as ok per mgr are recorded as a documentation habit, not yet a deficiency. The memo notes that a walkthrough confirms understanding and does not test operating effectiveness.
Seven steps, metal first
Gate, weigh-in, grading, unloading, weigh-out, pricing and payment, each beside the narrative sentence it tests and the procedure used to test it.
More than asking
Observation at the scale, inspection of the ticket and photos, and a recomputed price: 2,400 pounds at that morning's posted number two copper rate.
A photo of the pile
The grade photo shows copper already dumped on the ground, so it cannot prove what the truck delivered. The memo classifies it as a design gap.
One clerk, one kiosk
The Tuesday cash load was counted and inserted by a single office clerk with nobody verifying the count, a custody gap no amount of care would close.
Ok per mgr
Free-text override reasons accepted by the scale system, noted as a documentation habit and passed forward for the design matrix to reconsider.
Where marks go in AC557 Unit 4
Walkthroughs resting on interviews alone earn little, since hearing a scale operator describe the process confirms only that the operator knows the narrative. Graders expect observation, inspection or reperformance at nearly every step. Misclassification costs heavily too: a photo taken at the wrong moment is a design problem, not an operating one, because it fails even when done carefully, and a memo calling it a training issue misreads the evidence. Following several tickets partway, rather than one completely, misses the purpose of the exercise. Findings reported without the narrative wording beside them leave the reader unable to see the gap. Claiming the walkthrough proves the controls effective overstates what one ticket can show, and most instructors mark that claim down wherever it appears.

AC557 Unit 4 questions, answered
Is management's walkthrough the same as the auditor's?
Similar in method, different in owner and purpose. PCAOB AS 2201 frames walkthroughs for the external auditor, who uses them to confirm understanding and find points where misstatements could arise. This memo is management's, prepared for its own assessment under Section 404(a) within the parent's program. Both rely on inquiry, observation, inspection and reperformance.
Why is the photo problem a design gap rather than an operating failure?
Because the procedure as written lets the photo be taken after unloading, so even a grader following it exactly produces a picture that cannot show what the truck carried. An operating failure would mean a sound procedure performed badly. Classifying it as design changes the remedy from retraining people to relocating the camera.
Why follow only one ticket?
A walkthrough aims at understanding, and one transaction followed completely confirms each step and its controls more reliably than several followed in part. Whether controls operated across the year is a separate question answered with samples, which the next units cover. The memo names that limit in its closing paragraph so nobody reads more into it.
