Software craftsmanship is an approach to software development that emphasizes the coding skills of the software developers and the role of the software craftsmanship is often considered crucial in Agile methodologies such as Scrum. Here, I will discuss one of the key principles of software craftsmanship, namely, the principle of ‘continuous improvement’ and how it applies to the work associated with Certified Scrum Professional – ScrumMaster (CSP-SM) exam.
Continuous Improvement and CSP-SM
Continuous improvement, as the name suggests, emphasizes an ongoing effort to improve products, services or processes. It is vital in software craftsmanship and is integral to the Scrum eponym. Typically, these improvements are gradual and incremental in nature but can also be breakthrough in nature.
Role of CSP-SM:
A Scrum Master, certified by CSP-SM, plays a pivotal role in driving and fostering a culture of continuous improvement within the Agile team. The Scrum Master needs to ensure that the team continuously learns from its experiences and applies these learnings to forthcoming sprints. This aligns with the philosophy of software craftsmanship that emphasizes mastery and continual learning.
Fostering a Learning Environment:
Encouraging a learning culture within the Agile team is critical for continuous improvement. The Scrum Master, in the capacity of a coach and facilitator, promotes learning and sharing experiences among team members. The Scrum Master leads by example and cultivates a culture where everyone is open to learning and improving.
Highlighting Areas of Improvement:
Aligning with the principle of software craftsmanship, a CSP-SM is expected to be receptive towards areas that need improvements. This could relate to technical prowess, soft skills, Scrum practices or anything else that would add value to the product or enhance team’s productivity. Retrospectives serve as great platforms for Scrum Masters and teams to highlight these areas and act upon them.
Continuous Improvement in Scrum Events:
Continuous improvement is embodied in various Scrum events. For instance, during Sprint Planning, the Scrum Master and the development team not only decide what to work on for the next Sprint but also discuss how to improve the way of working based on previous experiences. During Sprint Retrospective, the team reflects on the past Sprint to identify potential improvements in their processes or work practices.
Example
Let’s take an example. Consider an Agile team working on a software product that had issues with code quality in the past sprints. A CSP-SM encourages the team to follow the principle of software craftsmanship and adhere to better coding practices to improve the quality of code.
By doing so, the Scrum Master fosters a culture of continuous improvement within the team, encouraging them to regularly inspect and improve their coding skills in line with the software craftsmanship principle.
Conclusion
To sum up, the principle of ‘continuous improvement’, that is integral to software craftsmanship, plays an important role in the CSP-SM’s repertoire of responsibilities. Besides, the principle aligns completely with the foundational ethos of Scrum, further highlighting its relevance and importance in the pursuit of CSP-SM.

Interview Questions
What is software craftsmanship?
Software craftsmanship is a set of principles, methods, and practices to produce software that is skillfully designed, reliably functional, and meets the clients’ needs. It implies a strong emphasis on professional development, continuous learning, and improvement of skills.
How does Test-driven development (TDD) apply to one’s work as an example of software craftsmanship?
Test-Driven Development (TDD) is a technique where the requirements are converted into very specific test cases. It makes sure that software code does exactly what the programmer intended it to do. This represents a crucial part of software craftsmanship, representing its stress on delivering functional, reliable software.
