1. Forecasting

Forecasting, in the supply planning world, is the craft of predicting future demand using history, market signals, and judgment to set inventory, capacity, and procurement on the right track.

Why It's Important

Reliable forecasts prevent stockouts and excess, sharpen service, and cut cost. Better plans, faster reactions, fewer surprises.

How to Improve Forecasting Skills

Make the numbers smarter and the process tighter.

1. Improve data quality: Clean, complete, timely data. Fix master data, align calendars, remove outliers thoughtfully.

2. Mine the past: Spot trend, seasonality, promotions, product life cycles. Segment by behavior—don’t treat all items the same.

3. Use the right math: Time-series models (moving average, exponential smoothing), causal drivers, even simple ML where it helps. Backtest and choose per SKU family.

4. Collaborate: Blend inputs from sales, marketing, finance, and key customers. CPFR-style rhythms reduce blind spots.

5. Sense demand: Pull in near-real-time signals—orders, POS, digital traffic—to adjust short-term plans fast.

6. Scenario plan: Build what-ifs for promotions, supply shocks, price changes. Plan B should be ready before you need it.

7. Continuously tune: Track bias and accuracy (MAPE, WAPE). Recalibrate parameters and prune models regularly.

2. Inventory Management

Inventory management is the control of what to buy, when to buy, and how much to hold—balancing availability with cost across raw materials, WIP, and finished goods.

Why It's Important

Right stock, right place, right time. Cash freed, service up, firefighting down.

How to Improve Inventory Management Skills

Cut noise, add discipline, build visibility.

1. Forecast tightly: Use item-location segmentation and align policies to demand variability and value.

2. Optimize parameters: Set service targets, safety stock, reorder points, and min/max using variability, lead time, and desired fill rates.

3. Differentiate control: Apply ABC/XYZ to tailor reviews, cycle counts, and replenishment frequency.

4. Strengthen suppliers: Shorter, steadier lead times. Dual source where it matters. Consider VMI or consignment for critical items.

5. Tighten processes: Cycle counting, root-cause adjustments, slotting and MOQ reviews. Eliminate slow movers with structured disposition rules.

6. Use technology: Integrate IMS/WMS/ERP for real-time balances, lot/serial tracking, and exception alerts.

7. Collaborate broadly: Sync with sales, ops, and finance on promotions, new items, and phase-outs.
