Concepts
Software craftsmanship is a mindset and an approach that puts the emphasis on the skill and the approach to the creation of software. It showcases the qualities of mastery, professionalism, and collaboration – elements very much needed in becoming a Certified Scrum Professional – ScrumMaster (CSP-SM). Now, let’s illustrate how at least one element of software craftsmanship, namely “Code Quality,” applies to the work of a CSP-SM with some relevant examples.
I. Understanding Code Quality as an Element of Software Craftsmanship
Code quality refers to the degree to which code conforms to functional and non-functional requirements (such as maintainability and readability), principles, and best practices. It includes elements such as good design, low complexity, high maintainability, readability, and high level of test coverage.
II. Incorporation of Code Quality in CSP-SM Role
As Scrum Masters, the focus is usually on facilitating scrum events, removing impediments, and coaching the team. However, maintaining code quality is a crucial aspect that cannot be overlooked. The CSP-SM, without directly addressing the code, should foster a culture of software craftsmanship which would, in effect, promote code quality.
III. Promoting Sustainable Development
Scrum principle #8 emphasizes the promotion of sustainable development. High-quality code reduces future bugs and facilitates easier modifications, thus reducing the risk of burned-out developers due to unnecessary work. A CSP-SM upholds this principle by fostering a culture emphasizing high-quality code.
For instance, a ScrumMaster could introduce a rule that no story is marked a ‘Done’ unless it reaches a certain level of test coverage. This way, code quality is prioritized, and technical debt is minimized.
IV. Building Projects around Motivated Individuals
The twelfth principle of Agile Manifesto encourages creating an environment where developers can show their craftsmanship. The CSP-SM could, for instance, ensure that pair programming – which promotes collective ownership, knowledge sharing, and coding standards – is implemented. By doing this, developers feel motivated as their skills are improved, and this would ultimately lead to good code quality.
V. Continuous Attention to Technical Excellence and Good Design
The ninth principle of the Agile Manifesto insists on continuous attention to technical excellence and good design. A ScrumMaster could ensure this by creating an environment for practices like code reviews, refactoring, and collective code ownership. This will enhance the team’s focus on maintaining a high standard codebase which is a testament to software craftsmanship.
To sum it up, while software craftsmanship stresses elements such as code quality, it’s not essentially about the code, but about the mindset and the behavior of the people who create the code. It is about seeing our work not just as a task but as a craft. As ScrumMasters, our role should not only be to facilitate the Scrum framework but to inspire and encourage a culture of quality, professionalism, skill sharing, and continuous learning. By instilling the principles of software craftsmanship, we can elevate the performance of our team and the quality of our products.

Explanation: The principles of Software Craftsmanship like creating clean, maintainable code helps the Scrum team manage and minimize Technical Debt.
Which Scrum Role should be most concerned with ensuring Software Craftsmanship principles are followed?
- A. Scrum Master
- B. Product Owner
- C. Development Team
Answer: C. Development Team
Explanation: It’s primarily the responsibility of the Development Team to ensure the principles of Software Craftsmanship are adhered to as they are the ones creating the product increments.
In terms of Scrum, where is the practice of Software Craftsmanship most likely to take place?
- A. Sprint Planning Meeting
- B. During the Sprint
- C. Sprint Review Meeting
- D. Sprint Retrospective Meeting
Answer: B. During the Sprint
Explanation: Software Craftsmanship primarily happens during the actual coding and development of deliverables, which occurs During the Sprint.
True or False: From a Software Craftsmanship perspective, it is generally acceptable to skip writing tests in order to meet a deadline.
- True
- False
Answer: False
Explanation: Software Craftsmanship prioritizes quality and maintainability, which typically includes the writing of tests to ensure code behaves as expected.
What is the main goal of a craftsman in relation to Software Craftsmanship?
- A. To finish tasks as quickly as possible
- B. To produce the highest quality work
- C. To learn as many programming languages as possible
- D. To maintain the highest code coverage in tests
Answer: B. To produce the highest quality work
Explanation: The aim of a true craftsman should always be to produce the highest quality work – speed and quantity should not be the defining factors. Software Craftsmanship emphasizes on quality coding.
The concept of ‘well-crafted software’ in software craftsmanship really resonated with me, especially in optimizing the workflow in our Scrum teams.
Emphasizing continuous improvement and personal growth is crucial. Mastering these elements has made a big difference in my CSP-SM journey.
Thanks for sharing this insightful post!
Constant communication and feedback loops are key elements I’ve focused on while preparing for the CSP-SM exam.
Great article, very helpful!
Incorporating practices like pair programming has significantly enhanced our team’s ability to produce quality software.
Focusing on delivering high-quality code has made my transition to CSP-SM much smoother.
Just wanted to drop a quick thanks!
