When not to use the Template Method Design Pattern?

• When Algorithms are Highly Variable: If the algorithms you’re working with vary greatly in their structure and steps, and there’s minimal commonality between them, using the Template Method pattern might not be appropriate as it may lead to excessive complexity or unnecessary abstraction.
• Tight Coupling Between Steps: If there’s tight coupling between the steps of the algorithm, such that changes in one step necessitate changes in other steps, the Template Method pattern may not provide sufficient flexibility.
• Inflexibility with Runtime Changes: If you anticipate frequent changes in the algorithm structure or steps at runtime, using the Template Method pattern might not be the best choice, as it relies on predefined structure and behavior.
• Overhead in Abstraction: If the cost of abstraction and inheritance outweighs the benefits of code reuse and structure enforcement, it’s better to avoid using the Template Method pattern and opt for simpler solutions.

The Template Method design pattern is a behavioral design pattern that defines the skeleton of an algorithm in a superclass but allows subclasses to override specific steps of the algorithm without changing its structure. It promotes code reuse by encapsulating the common algorithmic structure in the superclass while allowing subclasses to provide concrete implementations for certain steps, thus enabling customization and flexibility.
