Concepts
In the agile world, the capability for the Scrum Team to consistently deliver valuable and usable increments at the end of each sprint is mission-critical. However, certain development practices can profoundly impact this ability, either positively or negatively. This article will delve into two ways development practices may impact the Scrum Team’s ability to deliver as expected.
1. Test-Driven Development (TDD)
Test-Driven Development is a software development technique where developers write test cases for new functionality before writing the actual code. Adhering to TDD can influence the Scrum Team’s ability to present valuable increments in a number of ways.
- Quality Assurance: With TDD, each part of the software is thoroughly tested from inception, a practice that significantly reduces the chances of bugs and improves the quality of the software. This better software quality means the Scrum team can deliver usable increments to the customer with confidence.
- Design Improvement: TDD requires developers to think through the functionality in detail before writing the code. This encourages strong, clean designs and promotes better understanding of the scope among the team members –leading to more accurate estimation and planning, and hence successful completion of Sprint goals.
A potential downside to TDD could be that it might slow down the process initially. However, time savings are realized later in the project due to reduced debugging and maintenance.
2. Continuous Integration (CI)
Continuous Integration is a practice where developers frequently merge their code changes into a central repository. Automated builds and tests are then run to catch bugs early and allow for corrections to be made as soon as possible.
- Faster Feedback Loop: With CI, developers are promptly notified if their changes have introduced any issues. This swift feedback allows for immediate rectifications preventing bugs from ballooning into bigger problems. Therefore, the Scrum Team can maintain a steady rhythm of producing increments of value without having to halt or slow down due to setbacks.
- Ensured Code Quality: Regular automated testing ensures the code quality is consistently high. CI makes it possible to offer the customer usable increments at the end of every sprint, as the tested code is already integrated and ready to deliver.
One possible challenge with CI is that it requires an initial investment in test automation. Despite this, the long-term efficiency and quality gains can easily outweigh this upfront investment.
| Impact on Quality | Impact on Speed | Overall Impact on Scrum Team’s Ability | |
|---|---|---|---|
| TDD | Increases | Might decrease in the initial stages | Increases ability to deliver valuable, usable Increments |
| CI | Increases | Increases | Increases ability to deliver valuable, usable Increments |
In conclusion, the methodology the team follows plays a significant role in ensuring successful agile execution. Test-Driven Development and Continuous Integration are two practices that, when skillfully implemented within Scrum, can greatly improve the team’s ability to deliver valuable, usable increments at the end of each Sprint. These strategies can help establish a consistent, efficient, and high-quality delivery model, ensuring the success of the Scrum Team in their overall project execution.

Correct Answer: True
Single Select: Why is Continuous Integration a useful development practice for a Scrum team to deliver valuable, usable increments each Sprint?
- 1) It ensures that the partial code does not disrupt the functionality of the application.
- 2) It encourages more breaks for team members.
- 3) It increases the complexity of the project.
- 4) It delays the feedback process.
Correct Answer: It ensures that the partial code does not disrupt the functionality of the application.
Multiple Select: Which of the following agile practices enable a Scrum Team to deliver valuable and usable increments each Sprint?
- 1) Test-driven development
- 2) User story mapping
- 3) Just-in-time planning
- 4) Sequential software development
Correct Answer: Test-driven development, User story mapping, Just-in-time planning
True or False: Adapting to change and focusing on customer collaboration over following a plan and contract negotiation are two core values of agile development practices.
- 1) True
- 2) False
Correct Answer: True
One way that development practices impact the Scrum Team is through the use of Continuous Integration (CI). It helps catch bugs early, which can save the team valuable time in each Sprint.
Pair programming also has a significant impact. It not only improves code quality but also facilitates better knowledge sharing among team members.
Thanks for the informative post!
How does Test-Driven Development (TDD) affect the Scrum team’s delivery of Increments?
Automated testing can greatly enhance the team’s ability to deliver usable Increments by reducing the time spent on manual testing.
Appreciate the detailed blog post!
Code reviews are another development practice that helps improve the quality of work delivered by the Scrum Team.
