How do you check if your design patterns meet functional and non-functional requirements?

1 Define your requirements

The first step is to clearly define your functional and non-functional requirements. Functional requirements are what your system should do, such as features, functionalities, and behaviors. Non-functional requirements are how your system should do it, such as performance, security, reliability, and usability. You can use techniques such as user stories, use cases, scenarios, or specifications to document your requirements.

2 Choose appropriate design patterns

The next step is to choose the design patterns that best suit your requirements. There are many types of design patterns, such as creational, structural, behavioral, and concurrency patterns. Each design pattern has a name, a problem, a solution, and a consequence. You can use catalogs, books, articles, or online resources to learn about different design patterns and their benefits and drawbacks. You should also consider the context, trade-offs, and alternatives of each design pattern.

3 Apply design patterns consistently

The third step is to apply your chosen design patterns consistently throughout your code. You should follow the principles, guidelines, and best practices of each design pattern. You should also use naming conventions, comments, and documentation to make your code more readable and understandable. You can use tools such as code generators, templates, or frameworks to help you implement your design patterns.

4 Review and refactor your code

The fourth step is to review and refactor your code regularly. You should check if your code meets your requirements, follows the design patterns, and adheres to the coding standards. You can use tools such as code analyzers, code reviewers, or code quality metrics to detect and fix any issues or errors in your code. You can also use tools such as refactoring tools, testing tools, or debugging tools to improve and optimize your code.

5 Evaluate and validate your design patterns

The final step is to evaluate and validate your design patterns. You should measure and compare the results of your design patterns against your requirements. You should also collect and analyze feedback from your users, clients, or stakeholders. You can use tools such as surveys, interviews, or usability tests to assess the satisfaction, acceptance, and usability of your design patterns. You can also use tools such as benchmarks, performance tests, or security tests to verify the efficiency, reliability, and security of your design patterns.
