Guide: Understanding and Answering Questions on Pair Switching in PMI-ACP Exam

Pair Switching is a subset of Pair Programming, a key concept in PMI-ACP or Agile Certified Practitioner examination. It's important because it enforces principles of agile methodology such as collaboration, knowledge sharing, and collective ownership.

What is it?
Pair Switching refers to changing the programmer pairs in an agile team regularly. The main purpose is to ensure that every member of the team understands all parts of the project, thereby preventing any single point of failure.

How does it work?
In a typical pair programming environment, two programmers work together on one computer, one 'driving' or writing code, the other 'navigating' or reviewing each line of code as it's written. With pair switching, team members rotate roles and partners frequently, often multiple times per day.

Exam Tips: Answering Questions on Pair Switching
Always remember the rationale and benefits of pair switching such as spreading knowledge across the team and increasing software quality. Most questions on pair switching in PMI-ACP exam are scenario-based and requires understanding of its practical application and benefits. An important rule to follow while answering such questions is to reject answers that imply silos of knowledge, as they contradict the purpose of pair switching.

Pair Switching is a core concept of Pair Programming in which team members rotate their roles and partners consistently. This approach ensures that all team members have shared understanding and exposure to different parts of the project, promoting collective code ownership. Pair switching also ensures that there are multiple pairs of eyes checking the code at different stages, greatly reducing the likelihood of missed bugs or issues and enhancing the overall quality of the project. This process leads to better team bonding as well and promotes knowledge and skill sharing among team members, leading to improved professional skills across the team.
