1. State the operational objective
Decide what the placement change should improve: travel, congestion, replenishment effort, space use, or a defined combination. Describe the current burden with representative observations and measures. Choose the area, product population, and planning horizon. Avoid promising that one arrangement will maximize every objective simultaneously. Worksheet output: a statement of the desired improvement, non-negotiable constraints, baseline definitions, and the person responsible for deciding whether the result is useful.
2. Build a representative demand profile
Collect the order and transaction history appropriate to the objective. Distinguish units, lines, visits, and full-pallet activity. Note promotions, seasonality, new products, and unusual periods. Preserve the time window and known limitations. If order affinity matters, confirm that the data actually connects items within the relevant orders. Worksheet output: a demand profile with segmentation, history period, excluded anomalies, and the future conditions that could make historical demand misleading.
3. Validate item and packaging data
Review dimensions, weights, units, pack conversions, and handling requirements for the items in scope. Confirm which packaging level each measurement represents. Prioritize products associated with repeated capacity or cartonization exceptions. Use approved measurement methods and business ownership for corrections. Avoid assuming that a complete item file is accurate. Worksheet output: a validated data set, a list of unresolved fields, and a decision about which items cannot responsibly enter the analysis until their data is corrected.
4. Establish real location constraints
Document usable dimensions, capacity, access, location purpose, and approved restrictions. Include equipment and safe-handling constraints under qualified site guidance. Identify inactive, temporary, or physically blocked locations. Compare recorded availability with actual conditions and open work. Worksheet output: a location eligibility model that separates hard constraints from preferences, together with the evidence and owners supporting those rules. An optimizer should not be asked to discover physical restrictions that were never provided.
5. Connect placement to replenishment
Review forward-location capacity, replenishment quantities, source access, and the time available to restore stock. Estimate how a candidate placement changes replenishment frequency and traffic. Include demand-driven peaks and existing emergency patterns. A recommendation that shortens picking travel but creates constant urgent replenishment needs a clear tradeoff review. Worksheet output: a combined picking-and-replenishment assessment showing which changes improve the intended objective and which merely transfer work between teams.
6. Turn the selected changes into a move plan
Choose a bounded pilot and prioritize moves. Account for temporary space, equipment, labels, configuration, open allocations, and replenishment tasks. Define the sequence for changing physical and recorded locations and how each move is confirmed. Plan around an appropriate operating window and give exceptions a clear owner. Worksheet output: a controlled relocation plan with dependencies, responsible roles, verification evidence, and a recovery approach if the arrangement cannot be completed as intended.
7. Validate and revise with the people using it
Compare the agreed measures under reasonably comparable conditions and capture operator feedback. Check congestion, replenishment, errors, and completion flow as well as the primary objective. Note changes in demand that affect interpretation. Decide whether to extend the approach, adjust selected placements, or investigate a different constraint. Worksheet output: a pilot review connecting recommendations, executed moves, observed effects, limitations, and the next approved scope. Slotting remains an ongoing decision process as the operation changes.
