When to use this combo
You suspect your roadmap is full of "good ideas" that don't actually move the needle. Before prioritizing tasks, you want to step back and question whether you're even working on the right things. You want strategic clarity, not just task management.
Is this combo right for you?
Use this combo if you're a big-picture, strategic thinker who cares more about direction than speed. You worry about climbing the wrong ladder. Before optimizing execution, you want to make sure the goals themselves are right. If you often ask "But should we even be doing this?" — this combo matches your thinking style.
Step-by-step walkthrough
Start with First Principles — strip your roadmap back to fundamentals. What are you actually trying to achieve? What assumptions are baked into your current priorities?
Evaluate each initiative through Opportunity Cost — for each thing on your roadmap, explicitly ask: "What's the best alternative we're giving up to do this?"
Use a Decision Matrix with weighted criteria (strategic alignment, customer impact, revenue potential, effort) to score and rank what remains.
