Simple Design

5 minutes 5 Questions

Simple Design is another crucial concept related to Crystal Methods. It emphasizes the importance of simplicity in software design. The idea is to create the simplest possible design that achieves the desired functionality. This may seem easy but keeping designs simple can be a challenging task. De…

PMI-ACP - Simple Design Example Questions

Test your knowledge of Simple Design

Question 1

A team discovers that an existing feature in their product is over-engineered, making it complex to understand and maintain. In the context of Simple Design, what is the best approach for the team to take?

Ignore the issue as it's already built and functioning properly Refactor the over-engineered part of the product to simplify it, ensuring all functionality is preserved Increase the size of the team to manage the complexity Rewrite the entire product from scratch to ensure a clean start

Correct Answer: Refactor the over-engineered part of the product to simplify it, ensuring all functionality is preserved

In the context of Simple Design, the best approach when a team discovers an over-engineered and complex feature is to 'Refactor the over-engineered part of the product to simplify it, ensuring all functionality is preserved'. Refactoring involves modifying existing code to improve its structure without changing its functionality, which aligns with the concept of Simple Design. The aim is to reduce complexity and make the code easier to understand and maintain, without affecting the intended behavior. The other options are not ideal. 'Ignoring the issue as it's already built and functioning properly' does not address the problem of complexity and maintainability. 'Rewriting the entire product from scratch to ensure a clean start' is very risky, time-consuming, and potentially unnecessary. 'Increasing the size of the team to manage the complexity' does not remove the complexity; instead, it could lead to even more complexity and confusion.

Question 2

In a project, the team faces a requirement to increase performance. How should they approach this while maintaining simple design?

Add extensive documentation to justify the added complexity Increase hardware requirements to compensate Optimize the code by including complex algorithms Refactor the codebase entirely to focus on performance Ignore the requirement for increased performance Optimize the code without adding complexity

Correct Answer: Optimize the code without adding complexity

The team should optimize the code without adding complexity or sacrificing simplicity. This allows for improved performance while adhering to the principles of simple design.

Question 3

Which of the following is NOT a good practice for simple design in a project?

Including minimal documentation for complex code Breaking down complex problems into smaller tasks Writing code that is difficult to understand Refactoring to improve code quality Focusing on the most essential use case Removing unnecessary code duplication

Correct Answer: Writing code that is difficult to understand

Simple design emphasizes code clarity, maintainability, and simplicity. Writing code that is difficult to understand contradicts these principles.
