Developing by Feature

5 minutes 5 Questions

In FDD, the primary focus lays on features. A feature in FDD is a small, implementable chunk of functionality that delivers tangible and trackable results. This principle is beneficial because it facilitates shorter, more manageable iterations, allowing the progress to be measured by completed features. Each feature is developed in two weeks or less which makes the progress easily observable. Developing by feature encourages flexibility and improves the response to requirements changes.

Guide: Understanding and Applying the 'Developing by Feature' Concept in PMI-ACP

The 'Developing by Feature' concept is a vital component under the Feature Driven Development (FDD) model in the PMI-ACP exam.

Why it is important:
'Developing by feature' is key because it breaks down complex applications into manageable pieces, enabling a team to focus on delivering valuable, usable features. This approach encourages frequent delivery of working software, a core Agile principle.

What it is:
'Developing by feature' is an Agile approach in software development where a team works on single features. It incorporates planning, designing, developing, and testing individual features to completion.

How it works:
A feature is a specific piece of functionality that provides value to the customer. In 'Developing by Feature', the team: 1) Identifies a feature, 2) Designs and codes the feature, 3) Conducts code reviews, and 4) Tests the feature.

Exam Tips: Answering Questions on Developing by Feature:
1. Understand the process: First, make sure to grasp the sequence and steps involved in 'Developing by Feature'.
2. Customer Value: Questions often focus on the benefit to the customer. Recognize that this process promotes the delivery of valuable features to the client promptly.
3. Sequence of events: In a scenario question, look for clues about the sequence within the 'Developing by Feature' process.
4. Team Collaboration: The questions may also evaluate your understanding of how this approach impacts team collaboration.

Question 1

The development team discovers user needs for a particular feature have shifted. What agile principle would be most effective for handling these changes?

Designing new features unrelated to the changes Discouraging future feature changes Ignoring the changes and staying focused on the initial plan Avoid discussing the changes with the product owner Welcoming changing requirements, even late in development Completing the initial feature plan before addressing changes

Correct Answer: Welcoming changing requirements, even late in development

Agile project management involves responding to change and adapting to the evolving needs of users. Therefore, it is essential to welcome changing requirements at any stage.

Question 2

A team realizes that the scope for a specific feature is too large to complete in a single sprint. What should the team do?

Exclude the team from the decision-making process Change the entire project scope Work longer hours to finish the entire feature Cancel the sprint to reevaluate the project plan Break down the feature into smaller, more manageable parts Skip the feature and move to the next priority

Correct Answer: Break down the feature into smaller, more manageable parts

Breaking down large features into smaller, manageable parts allows the team to maintain their agility and deliver value incrementally. This approach ensures that each part is attainable within a given sprint.

Question 3

In your agile team, you have been assigned to develop a feature which requires certain underlying components to work correctly, but those components haven't been fully developed yet. How would you handle this situation?

Start developing your part and adjust it later when the underlying feature is ready. Proceed with your part of development by making assumptions about the underlying feature. Communicate with other team members and coordinate the development process accordingly. Wait for the underlying features to be developed and then start with your part.

Correct Answer: Communicate with other team members and coordinate the development process accordingly.

In an agile team setting, collaboration and communication are of utmost importance. If you encounter a situation where your task relied on components not yet fully designed, the best way to handle this would be to talk with other team members who are responsible for developing those parts. This will not only help you coordinate your tasks but also ensure a smooth process for integrating the different parts of the project. Starting development on your part without fully understanding or having the underlying features in place (as suggested in the other answers) could lead to incompatible design, wasted time and effort, and could even cause potential issues for the overall project. Therefore, the best approach is to communicate with your team members and coordinate the development process accordingly.
