In agile project management, when a new technology is introduced and results in a decrease in team velocity, it is essential to use retrospectives to analyze the situation. Retrospectives allow the team to reflect on what has happened, identify any skill gaps, and understand the impact of the new technology on the project's schedule. This understanding can then be used to make necessary adjustments to the team composition or process to improve velocity1. References: Increasing Your Scrum Team's Velocity - ClearlyAgile1.
