I fumbled the opening because I went straight to picking a language instead of addressing the people problem first.
Frame the disagreement as a technical decision that should be driven by product requirements, team expertise, and long-term maintainability. Demonstrate a structured decision-making process that includes gathering input, evaluating trade-offs, and making a final call as the lead PM. Emphasize that the chosen language should align with the product's goals and the team's ability to execute efficiently.
Pro tip: Acknowledge that at Google, language choices often depend on existing infrastructure and team familiarity; showing awareness of Google's internal tech stack (e.g., Go for backend, TypeScript for frontend) can set you apart. Also, emphasize that the decision should be reversible if possible, and focus on delivering value over winning the argument.
Meet with each cross-functional team to understand their technical preferences, concerns, and constraints. Identify the root causes of disagreement, such as performance needs, existing expertise, or integration challenges.
Establish objective criteria for the decision, such as scalability, development speed, ecosystem support, hiring availability, and alignment with product roadmap. Ensure all teams agree on these criteria.
Facilitate a workshop where each team presents their preferred language and how it scores against the criteria. Use data and prototypes if needed to compare performance and developer productivity.
As the lead PM, make the final call based on the evaluation, even if consensus isn't reached. Clearly communicate the decision, the reasoning, and how it aligns with product goals, and acknowledge the trade-offs.
Outline a migration or adoption plan, including training and support. If feasible, design the architecture to allow future changes, and set a review point to reassess the decision.
