Scrum2Kanban: Integrating Kanban and Scrum in a University Software Engineering Capstone Course

Slides for the talk at the Second International Workshop on Software Engineering Education for Millennials (SEEM'18, http://seem2018.se-edu.org/), colocated with the 40th International Conference on Software Engineering (ICSE'18) in June 2018.

Abstract:
Using university capstone courses to teach agile software development methodologies has become commonplace, as agile methods have gained support in professional software development.
This usually means students are introduced to and work with the currently most popular agile methodology: Scrum.
However, as the agile methods employed in the industry change and are adapted to different contexts, university courses must follow suit.
A prime example of this is the Kanban method, which has recently gathered attention in the industry.
In this paper, we describe a capstone course design, which adds the hands-on learning of the lean principles advocated by Kanban into a capstone project run with Scrum. This both ensures that students are aware of recent process frameworks and ideas as well as gain a more thorough overview of how agile methods can be employed in practice.
We describe the details of the course and analyze the participating students' perceptions as well as our observations. We analyze the development artifacts, created by students during the course in respect to the two different development methodologies.
We further present a summary of the lessons learned as well as recommendations for future similar courses. The survey conducted at the end of the course revealed an overwhelmingly positive attitude of students towards the integration of Kanban into the course.

  1. Scrum2Kanban: Integrating Kanban and Scrum in a University Software Engineering

  2. Research Questions 4 ▪ What are students’ perceptions of Kanban

    practices? ▪ Are those perceptions accurate? ▪ How does using Kanban influence workflows?
  3. Survey General Attitude 6 ▪ Positive attitudes towards including Kanban

    ▪ Recommended ▪ Good understanding of agile ▪ Preferred over last Scrum week ▪ Neutral towards additional lectures, high variance Sanity Check
  4. Survey Extract of Attitudes towards Kanban 9 ▪ Advantages of

    Kanban ▪ Drawbacks of Kanban ▪ Change in User Stories / Requirements
  5. Development Data Analysis Artifacts 10 ▪ Length (title, body) ▪

    # Comments ▪ # Interactions ▪ Opened/Closed by ▪ Assignee Commit History User Stories ▪ Count ▪ Files changed ▪ Insertions ▪ Deletions ▪ Merge?
  6. Findings User Stories 11 User Stories were shorter when using

    Kanban ▪ Mean body length was lower (513 vs. 367 chars), but not titles ▪ Support for perception of US contents More dynamic interaction with US during Kanban ▪ Only ~⅔ of user stories created by POs (vs 85%+ in Scrum) ▪ Support for perception of autonomy Uneven task distribution ▪ Not fixed by Kanban, # unique assignees did not significantly change ▪ Support for perception ▪ Identified need for improvement
  7. 12 More commits ▪ More non-merge commits (138 vs 289)

    ▪ Support for hypothesis Smaller commits ▪ Diff sizes similar ▪ Hypothesis not validated Problem with Merges in Kanban ▪ Mean amount of merge commits per week almost tripled (52 to 142) ▪ Support for perceptions ▪ Need for improvement Findings Commits
  8. Conclusions 13 ▪ Students’ software development data ▪ Another dimension

    of analysis ▪ Addition to surveys ▪ Artifacts in SE always produced, already there ▪ Not everyone fills out voluntary survey
  9. 14 ▪ Students’ software development data ▪ Another dimension of

    analysis ▪ Addition to surveys ▪ Artifacts in SE always produced, already there ▪ Not everyone fills out voluntary survey ▪ Contrasting perceptions and data can reveal areas of improvement / further research Conclusions
