apply a collaborative development practice.

The Advanced Certified Scrum Developer (A-CSD) is an accreditation that signifies proficiency in Agile and Scrum principles and the ability to apply them in practical development scenarios. One noteworthy aspect in this context is the application of collaborative development practices, which essentially means working together as a team to ensure a project’s success.

Collaborative Development Practice

Collaborative development is a practice where multiple individuals, often with different expertise, work together on a project to produce high-quality output. It relies heavily on continuous communication, continuous integration, shared ownership, common coding standards, collective decision-making, and other such practices.

Why Collaborative Development?

Applying collaborative development practices can significantly improve team output. Key advantages include faster problem solving, increased innovation, improved learning, higher employee satisfaction and better project ownership.

For example, consider a scenario where a coding issue arises. In a traditional individual work approach, the concerned person might spend significant time solving it. In a collaborative environment, however, this can be rapidly addressed with multiple people bringing different perspectives to the problem-solving process.

Applying Collaborative Development Practices toward A-CSD Accreditation

A significant component in A-CSD examination involves demonstrating knowledge and proficiency in the application of collaborative development practices. Candidates should thoroughly understand concepts like pair programming, code reviews, and collective code ownership.

Pair Programming

Pair programming, a cornerstone of collaborative development, involves two programmers working together at one workstation. One person, the “driver”, writes the code while the other, the “observer”, reviews each line of code as it’s written. This real-time review significantly improves code quality and reduces bug-introduction.

Comparatively, while pair programming may seem to be less productive initially as it involves two people consistently in a single task, it usually leads to higher code quality, less debugging work, and better software design that more than compensates for the initial “Slowness”.

Code Reviews

Code reviews add an extra layer of scrutiny to the development process. In this step, other team members review the written code for any potential flaws or improvements. Beyond improving code quality, this also gives team members the opportunity to learn from each other’s skills and experiences.

For instance, smaller organizations can create a procedure for more experienced developers to perform reviews on junior developers’ codes. This not only enhances the code’s quality but also provides a valuable learning opportunity for junior developers.

Collective Code Ownership

Collective code ownership is another crucial aspect of the A-CSD exam. It implies that no specific piece of code belongs to any one individual, and every team member can make changes to any part of the code.

Comparatively, check out the two scenarios:

• Scenario A (No collective code ownership): Developer X is the only person familiar with a segment of code, and when that code breaks while Developer X is unavailable, the entire work stalls.
• Scenario B (Collective code ownership): Every developer is familiar with all code segments. So when one segment breaks, any available developer can fix it.

Scenario B is obviously more effective for team productivity and is a fundamental principle of Scrum.

In conclusion, recognizing and implementing collaborative development practices is vital for earning A-CSD certification and more importantly for aiding in a team’s success. Remember that while individual talent is essential, collaboration amplifies the overall team’s effectiveness.
