Question: Write a short essay explaining why a team might choose to have engineers work on Great Cats and Blurry images at the same time, and what condition must be met for this to be feasible.

Sample answer: Pursuing multiple error categories in parallel allows a team to make progress on more than one source of errors simultaneously, rather than addressing them one after another. This is only feasible when the team has enough people, since each error category requires dedicated attention from engineers. For example, some engineers can focus on improving performance on Great Cats while others address Blurry images at the same time, speeding up overall progress.

Key points:

• Parallel work requires the team to have enough people
• Different engineers are assigned to different error categories
• Great Cats and Blurry images are named example categories
• Parallel work can help address multiple error sources more efficiently

Rubric: Full credit for explaining that parallel work is possible only with sufficient staffing, that it involves assigning different engineers to different error categories, and that it can speed up progress; partial credit for addressing only one of these points.
