What is the immediate impact on the productivity of the original Scrum Team when two additional Scrum Teams are added to the development of a product?

When two additional Scrum Teams are added to the development of a product, the immediate impact on the productivity of the original Scrum Team is likely to decrease. This can be attributed to several factors inherent in scaling Scrum across teams.

First, coordination costs tend to rise with the addition of more teams. Communication hurdles can emerge as teams need to sync their efforts, share information, and align their work towards common goals. Increased communication can divert attention from development activities, temporarily affecting the original team's productivity.

Additionally, as multiple teams interact, dependencies may arise. Managing these dependencies can create bottlenecks that hinder workflow, requiring additional time for the original team to accommodate the needs of the new teams rather than focusing solely on their own tasks.

Furthermore, there is often an initial adjustment period when new teams are integrated into an ongoing project. The original team may need to invest time in onboarding, sharing knowledge, and aligning with the new teams regarding product goals, practices, and methodologies.

These dynamics contribute to a scenario where the original Scrum Team’s productivity is likely to decrease upon the introduction of additional teams. As teams work to establish their processes and ensure effective collaboration, the impact on the original team’s output can manifest as decreased productivity in the short term.
