Incremental Delivery

Correct Answer: Deliver the other two features and fix the faulty feature in the next increment.

Delivering the two features that meet quality criteria while fixing the faulty feature in the next increment ensures that the project progresses while maintaining quality standards.

Correct Answer: Address the concern by reviewing the latest increment with the customer.

The correct approach is to address the customer's concern by reviewing the latest increment and making necessary changes. Ignoring concerns, suspending the project, or switching to another model doesn't provide a solution to the customer's issue.

Correct Answer: Address the feature problem immediately and include it in the next delivery increment.

In an incremental delivery system, customer feedback is a critical part of the process. Thus upon receiving feedback that a critical feature is not functioning as expected, the project manager should 'Address the feature problem immediately and include it in the next delivery increment.' This allows for the addressing and correction of issues as they are discovered, ensuring a functional product in each increment. The option to 'Ignore the customer's feedback and proceed as planned' is an inappropriate response as ignoring customer feedback undermines the purpose of the incremental delivery model which is to incorporate feedback and enhance the product accordingly in each iteration 'Prioritizing other features over the problematic one' can potentially lead to an overall less functional product which would not be beneficial for the customer. Since the feedback concerns a critical feature, it is important to address it promptly 'Scrapping the entire project and start from scratch' is unnecessary and wasteful as problems arising during incremental delivery can simply be addressed in subsequent iterations, reducing the need for extensive rework.
