Abstract
This paper examines the role of the enterprise social networking (ESN) tool Slack in the daily work of software practitioners within NAV, a large-scale agile public sector organization. Based on 13 interviews with NAV developers, our case study explores how Slack is employed for knowledge sharing and daily communication across the organization. We used a newly developed framework for communication in agile teams as a theoretical lens. Through our analysis, we found that Slack use had become deeply integrated into the organizational culture and fostered alignment in three main ways: Promoting communication transparency through open discussions visible for developers organization-wide, enhancing communication quality with prompt responses and constant communication, and encouraging communication discipline through structured channels and threads. This study also unveiled some challenges, such as information overload and hindered focus. However, our findings suggest that if common hurdles are overcome, modern ESN tools can reshape how cross-organizational communication plays out in large-scale agile, reinforcing the agile principles of collaboration and motivated individuals.
