Modular design in creating reusable components
Modular design in creating reusable components
Break program into independent modules performing specific tasks
Parameterisation in creating reusable components
Parameterisation in creating reusable components
Use parameters to make components flexible to different inputs
Drawback: Initial development time
Drawback: Initial development time
Takes more time initially due to thorough design and testing needs
Drawback: Complexity of reusable components
Drawback: Complexity of reusable components
Highly reusable components can become complex and hard to understand
Common mistake: Overengineering
Common mistake: Overengineering
Making components too generic/flexible leads to unnecessary complexity
