PMI Agile Certified Practitioner (ACP) Practice Exam – Prep & Practice Questions

The term that refers to the reorganization of existing code without affecting functionality is refactoring. Refactoring involves modifying the internal structure of code while maintaining its external behavior and operational functionality. This process helps improve the code’s readability, reduce its complexity, and enhance maintainability without changing the underlying logic or output of the program.

Refactoring is critical in software development because it enables teams to manage code effectively, allowing for easier enhancements and bug fixes down the line. By adhering to good refactoring practices, developers can create a cleaner codebase, ultimately leading to more efficient development processes and improved software quality.

In contrast, prototyping refers to creating preliminary models of a product to test concepts or gather user feedback; quality assurance involves systematic monitoring and evaluation of various aspects of a project to ensure standards are met; and iteration is a process in Agile where work is done in cycles, leading to continuous improvements and development of the product. These concepts do not specifically focus on reorganizing existing code while preserving its functionality as refactoring does.
