Supply Chain & Capacity Planning

Match capacity to demand with practical, approachable models for inventory policy, supplier coordination, and capacity management—so your team minimizes stockouts, excess, and late deliveries while keeping working capital in check.

Why this matters

Every organization faces variability: changing customer demand, supplier delays, seasonal swings, and production hiccups. Poorly designed inventory and capacity decisions either leave customers waiting or tie up cash in excess stock. This resource focuses on simple, actionable methods teams can use to set reorder points, size safety stock, coordinate with suppliers, and plan capacity so operations become more predictable and resilient.

What you will learn and do

You will learn how to:

• Choose inventory policies (reorder point, periodic review) that fit your lead times and demand variability.
• Calculate safety stock and reorder points using straightforward, explainable formulas and scenarios.
• Coordinate with suppliers to shorten and stabilize lead times, create clear replenishment agreements, and manage risk collaboratively.
• Plan production and labor capacity to smooth flow, avoid peaks that cause emergency overtime or missed orders, and use buffers thoughtfully.
• Run simple scenario analyses to understand the trade-offs between service level, inventory cost, and lead‑time risk.

Practical examples

Examples show how concepts map to real work:

• A small roofing contractor sets reorder points for shingles and coordinates deliveries to match weekend jobs, avoiding missed installs and costly rush orders.
• A regional food distributor calculates safety stock for high‑volume SKUs across winter months and negotiates shorter lead‑time windows with suppliers to reduce spoilage risk.
• A community clinic plans PPE and medication reorder cycles, balancing storage space limits with patient safety needs.
• A manufacturer uses a starter capacity model to level daily production runs, reduce changeover times, and prevent overtime spikes during peak demand.

What's included

This resource contains a Supply Chain & Capacity Planning Workbook and a starter supply‑chain model you can use to test policies against sample data. Use them to document current practices, run simple calculations, and compare scenarios before changing operational rules.

Next steps and how to adapt this to your organization

Begin by using the workbook to capture current lead times, order frequencies, and demand variability for your top SKUs or services. Load those figures into the starter model to see how different safety‑stock and reorder‑point choices affect service levels and average inventory. If you manage multiple sites, consider copying the workbook and tailoring parameters for each location rather than forcing a single policy everywhere.

Platform opportunities: turn checklists or audits from the workbook into saved interactive forms to collect inventory counts, supplier lead‑time observations, and replenishment exceptions; store responses for later analysis. When appropriate, package repeatable tools (workbook + localized model) as a site toolkit so teams can own and evolve them.
