Capacity constraints in companies include limitations on time, labor, equipment, and facilities. Demand patterns can be predictable cycles or random fluctuations and vary by market segment. Charting demand over time allows companies to understand typical patterns. Strategies to match demand and capacity include shifting demand to non-peak times through incentives, prioritizing loyal customers, and adjusting prices. Companies can also flex capacity by stretching resources, cross-training employees, renting/sharing assets, and outsourcing during peaks or performing maintenance during valleys.
