Factory Method Pattern Explained Using a Restaurant Kitchen Analogy

A software design tutorial on DEV Community breaks down the Factory Method pattern using a restaurant analogy, where code requesting an object acts as the customer and a dedicated factory class acts as the kitchen. The pattern centralises object creation in one place rather than scattering conditional logic across multiple files. Using a C# notification system as an example, the author shows how a single NotificationFactory class can create Email, Teams, or SMS senders without callers needing to know which class they receive. The key benefit is maintainability: adding a new notification type requires changes in only one factory class instead of editing dozens of files. The article is the second in a beginner-focused series on C# design patterns, following a piece on Singleton and ahead of a planned instalment on the Builder pattern.
