Should all increments from multiple Scrum Teams working on the same product be integrated every Sprint?

The idea behind integrating increments from multiple Scrum Teams working on the same product every Sprint is fundamental to ensuring a cohesive product. The correct answer highlights that integration should be done only if there are dependencies between teams.

When multiple teams work on different aspects of the same product, it is vital to identify and manage interdependencies. If one team's work or increment depends on another team's work, then integration becomes essential during the Sprint to ensure that the combined product increment is functional and meets the desired goals. This frequent integration allows for early detection of issues related to dependencies and fosters collaboration across teams, which is crucial for delivering a high-quality product increment.

Moreover, working in this manner enables teams to adapt their work based on the feedback received from the integrated increments. It encourages communication, reduces potential integration problems, and enhances alignment on what needs to be delivered.

By focusing on dependent increments, the teams can prioritize integration efforts where they are most needed while still following the principle of delivering a potentially shippable product increment at the end of each Sprint. This approach supports effective risk management and improves overall product coherence, leading to better final outcomes.
