Field notes from
the planning desk.
Three series — planning school, build notes, and India ops. One useful post a week, no drip campaigns, and every claim links to something you can check.
Safety stock, shown honestly: the formula, the assumptions, and when it lies
The safety-stock formula is one line of algebra resting on three assumptions your demand quietly violates. Here is the whole thing, in the open.
Build notesWhy our forecast engine refuses to forecast — and yours should too
A forecasting engine that never says "I don't know" is not confident. It is lying with extra steps. Here is why refusal is a feature we built on purpose.
India opsPlanning around Diwali: the event uplift your spreadsheet can't learn
Festival demand is not noise to be smoothed away — it is signal to be graded. Why a scheme calendar beats a seasonal index for Indian demand.
Planning schoolWAPE vs MAPE vs MASE: which accuracy number is lying to you today?
Three forecast-accuracy metrics, three very different lies. A field guide to reading the number before you trust it.
Build notesThe trust badge on every number: why we rung-rate our own outputs
Measured, computed, estimated, default. Four badges that travel with every number in the product — and why provenance beats precision.
Build notesNo data without a contract: how we map your ECC fields (and report every column we drop)
The one rule that governs every byte entering SangamIQ from your ERP — and why "we'll just ingest everything" is exactly the wrong answer.
