Your question is Roadmap With Competing Priorities. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are leading an engineering team that needs to deliver against several important priorities at once: new product commitments, reliability work, technical debt reduction, and internal platform improvements. Different stakeholders are pushing for different outcomes, and each believes their work is the most urgent. You need a roadmap that is credible, executable, and resilient when priorities inevitably shift.
How would you build and execute a roadmap for an engineering team that has multiple competing priorities?
