Incremental Delivery

5 minutes 5 Questions

Incremental Delivery is a core part of Scrum wherein the product is developed and delivered in small, usable segments. This allows stakeholders to provide early and frequent feedback, which in turn enables the Scrum Team to align the product with the user needs more effectively. This approach also helps in reducing project risk by providing increments of real value and presents opportunities to adjust the project direction based on the received feedback.

Guide to Incremental Delivery in Scrum

Incremental Delivery: It is the practice of building and delivering pieces of value incrementally rather than as a whole at the end.
Why it's important: Incremental delivery helps in managing the risks associated with the project. It enables faster detection of issues, encourages early feedback, and facilitates course corrections.
How it works: It involves breaking down the project into smaller, manageable tasks (or increments). These are then developed, tested, integrated, and delivered iteratively.
Exam Tips - Answering Questions on Incremental Delivery:
1. Understand the concept thoroughly: To answer questions correctly, one should have a deep understanding of the concept of incremental delivery.
2. Relate it to practical scenarios: Questions often test the ability to apply theoretical knowledge practically. Thus, think about how incremental delivery would work in a real project situation.
3. Revise key benefits and implications: Be clear about why incremental delivery is preferred in Scrum and how it impacts the overall project.
4. Use appropriate terminology: Use appropriate Scrum/Agile vocabulary. For example, terms like 'increments', 'iterations', 'backlogs', etc. should be used appropriately.
Remember, oftentimes, understanding the concept is more important than memorizing it. So, make sure you understand what incremental delivery is, why it is implemented and what results it could bring.

PSM I - Incremental Delivery Example Questions

Test your knowledge of Incremental Delivery

Question 1

Your team is following incremental delivery for a software project. The latest increment consists of three new features, but the testing team identifies that one of the features does not meet the quality criteria. What's the best course of action?

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.

Question 2

A project manager leads an incremental delivery software project. After the second increment, the customer provides feedback that a critical feature is not functioning as expected. What should be the project manager's immediate step?

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.

Question 3

A project team has been working on a software project with an incremental delivery approach. The customer is concerned about the functionality delivered in the latest increment. What should the project manager do?

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.
