Suppose a team member submits a code change that introduces a bug. How would you use a collaboration platform to identify and address the issue?
- Comment on the code directly within the collaboration platform, initiate a discussion thread, and assign tasks to fix the bug
- Document the bug in a separate file, communicate via instant messaging, and assign blame to the team member
- Ignore the bug since it's the responsibility of the team member who introduced it, resolve it individually without involving the team
- Send a private email to the team member pointing out the issue, discuss it during the next team meeting, and wait for the next sprint planning session
Using the collaboration platform, such as commenting on the code and initiating discussions, helps identify and address the bug collaboratively. Assigning tasks and discussing the issue within the platform ensures a transparent and organized approach to bug resolution.
