Consensus: A group of people reaching a mutually agreed-upon decision. In practice, it often means hours of discussion leading to decisions that everyone supposedly agrees to, but that no individual can be held accountable for.
Collaboration: Individuals work together for a shared purpose — they may not concur on everything each step of the way, but they do agree on the final outcome.
Alignment: Concerted effort to help people agree on desired outcomes, understand the issues, and contribute to a decision. People with differing opinions can still commit to test a course of action and judge based on results. Alignment is not consensus.
When you are a product person looking to get a roadmap in place, you need alignment and collaboration. You don’t need consensus. Really. Read about "Achieving, Alignment and Buy-in" in Chapter 8 of my book, Product Roadmaps Relaunched. Agree with me? Disagree? Tell me a story.
