Build Quality In

5 minutes 5 Questions

Build Quality In refers to the practice of designing and developing the software in a way that ensures high quality from the beginning. Unlike traditional approaches that focus on fixing defects after the product is complete, Lean Software Development emphasizes on preventing defects during the development process. Teams can achieve this by following best practices, such as code reviews, automated testing, and continuous integration. This concept helps in reducing the overall time and effort spent on fixing bugs, which leads to a faster and more efficient product delivery.

Guide: Build Quality In - Lean Software Development

What is Build Quality In?
Build Quality In is a lean software development practice where focus is on creating error-free codes to reduce waste and defects. Instead of focusing on detection of bugs, emphasis is laid on prevention.

Why is it important?
Building Quality In helps to eliminate waste, saves time, reduces costs, and increases customer satisfaction. By avoiding defects, companies can save the cost and time required to fix errors later. A higher quality product also results in happier, more loyal customers.

How does it work?
This works by integrating quality into every process from the start. This includes practices such as Test-Driven Development (TDD), Continuous Integration (CI), and Pair Programming. Testing is done throughout development, not just at the end, reducing the chance of any big issues not being caught until late in the process.

Exam Tips: Answering Questions on Build Quality In:
Understand the concept in depth: Be clear on what Build Quality In stands for and how it helps in reduction of waste and cost.
Remember the Practices: Practices like Test-Driven Development (TDD), Continuous Integration (CI), and Pair Programming can be helpful while answering questions based on this topic.
Relate it to other Agile practices: Understand how Building Quality In fits in with other Agile practices, such as customer-focused value and sustainability.
Examples always help: Concrete examples can make your answers stronger, for example, how implementing TDD helped in catching bugs early and thus reducing the overall time in fixing it later.

Question 1

An Agile team member is consistently delivering code with several defects despite using TDD. What can your team do to improve code quality?

Require lengthy design documents Conduct code reviews Extend deadlines Skip meetings Work overtime Increase team size

Correct Answer: Conduct code reviews

Conducting code reviews is an effective way to ensure that team members understand the code base and can spot potential issues. Skipping meetings, working overtime, extending deadlines, requiring lengthy design documents, or increasing team size do not directly improve code quality.

Question 2

During a sprint review, a client complains that a delivered feature has a different behavior from what they expected. What can your team do to prevent similar issues in the future?

Hire more developers Allocate more time for development Ignore client's feedback Improve communication and collaboration with the client Decrease meeting frequency Shorten sprint lengths

Correct Answer: Improve communication and collaboration with the client

Improving communication and collaboration with the client ensures that the team understands their needs better, which can prevent similar issues in the future. Allocating more time for development, decreasing meeting frequency, shortening sprint lengths, hiring more developers, or ignoring client's feedback are not effective at preventing misunderstanding of requirements.

Question 3

Your team is consistently delivering features with numerous defects. As a project manager, what practice can help address this issue?

Increase sprint length Pair programming Request additional funding Change the project management tool Reduce team size Add more stakeholders

Correct Answer: Pair programming

Pair programming is a technique where two developers collaborate on the same code, which helps improve code quality and reduce defects. Increasing sprint length, reducing team size, adding stakeholders, requesting additional funding, or changing the project management tool do not address the root cause of poor code quality.
