  Team collaboration among individuals with diverse sets of expertise and
skills is essential for solving complex problems. As part of an
interdisciplinary effort, we studied the effects of Capture the Flag (CTF)
game, a popular and engaging education/training tool in cybersecurity and
engineering, in enhancing team construction and collaboration. We developed a
framework to incorporate CTF as part of a computer-human process for expertise
recognition and role assignment and evaluated and tested its effectiveness
through a study with cybersecurity students enrolled in a Virtual Teams course.
In our computer-human process framework, the post-CTF algorithm using the CTF
outcomes assembles the team (assigning individuals to teams) and provides the
initial role assignments, which then gets updated by human-based team
discussions. This paper shares our insights, design choices/rationales, and
analyses of our CTF-incorporated computer-human process framework. The
students' evaluations revealed that the computer-human process framework was
helpful in learning about their team members' backgrounds and expertise and
assigning roles accordingly made a positive impact on the learning outcomes for
the team collaboration skills in the course. This experience report showcases
the utility of CTF as a tool for expertise recognition and role assignments in
teams and highlights the complementary roles of CTF-based and discussion-based
processes for an effective team collaboration among engineering students.
