Planning and allocation roles from A to Z — the W page of the category index
No planning role description in this category begins with W, so the W page is an honest blank — kept, like every empty letter, so the A-to-Z index has no gaps. W is a fitting letter for one true thing about this category, though: planning work runs by the week. The notes below describe that rhythm, then point you to the fourteen roles under A, C, F, I, M, P, R and S.

Seasons are planned in months, but they are managed in weeks. Each week the sales figures land and the planning team reads them the same way: which categories beat plan, which styles are selling through faster than expected, where stock is building instead of moving. Weekly trading meetings turn that reading into decisions — chase a winner, promote a slow line before it becomes a clearance problem, shift stock between stores while season remains to sell it in. Almost every role here lives inside that weekly cycle.
The Forecast Analyst (Inventory) projects stock positions week by week; Replenishment under R works to weekly cover targets; the Inventory Coordinator keeps the stock record the weekly numbers are built from accurate daily. Allocation under A is decided in weekly drops to stores. Read together, those four descriptions show how a planning department actually spends its weeks, and the Planning and Allocation hub gathers all fourteen roles in one list.
It would be tidier to delete W, and worse: a missing letter looks like a broken page rather than an honest answer. This page therefore stays, marked as holding no descriptions, until a genuine W planning title establishes itself. Nothing here is padded with borrowed or invented jobs — the section's depth lives in its fourteen real role pages.
None in this category. The Planning and Allocation index holds 14 role descriptions under A, C, F, I, M, P, R and S, and the W page exists to keep the alphabetical index complete.
Because the week is planning's working unit: sales are read weekly, stock projected weekly, replenishment and allocation decided weekly. It is the most useful true thing an empty W page can explain.
Use the Planning and Allocation hub, which lists all 14 roles under anchored letter sections, or the letter bar near the top of this page.
