The described condition is fundamentally Poor Team Collaboration. Large Scrum projects depend on effective interaction among multiple Scrum Teams, particularly where deliverables, dependencies, shared components, or resources cross team boundaries. If teams begin working in isolation, communication decreases and coordination problems can develop even when each individual team appears internally productive.
The Scrum of Scrums mechanism exists specifically to improve coordination among multiple Scrum Teams by sharing progress, dependencies, impediments, and work that could affect other teams. Failure to communicate across those boundaries undermines one of Scrum's core principles—Collaboration.
Technical debt refers to accumulated future cost or rework caused by expedient technical decisions, incomplete engineering practices, or deferred quality work; that is not what the scenario describes. A risk is an uncertain event, whereas the lack of communication is already occurring. It could produce issues or risks, but its immediate organizational diagnosis is poor collaboration.
Thus, the Chief Scrum Master should identify this as a team collaboration problem and facilitate mechanisms that restore transparency, coordination, and cross-team communication.
