Consensus is time-consuming agreement, accord. Consensing instead is defined as having no significant objection. It does not require agreement, affirmation or even preference. Consent is reached by choosing the proposal with the least objections. The lowest level of objection — resistance — results to the highest acceptance.
You can kill your business or any change initiative easily by traditional consensus-based decision-making. However, you can boost your organizational decisioning dramatically by systemic consensing. Systemic Consensing does not require any alignment of agreements, affirmation or even preference but rather an alignment of tolerances. The consent is reached by choosing the proposal with the least objections only.
There are several methods for Decision-making you can use in group decisioning or group facilitation. All of these are variants of Consensus-based decisioning or Majority Voting — aka Democratic Voting. A completely different approach is systemic consensing.
A vision is stable and is part of the company identity. The vision is the Enterprise's “North Star”, and it should guide each and every decision your company makes. The vision is the embodiment of the brand and the reason the company exists. You pitch the vision. The mission is the strategy to carry out your vision. The mission should change — whether due to customer feedback, learning from experiments, market forces, etc. However, the vision can not change. If it does, that's not a "pivot" — that's a new company! Always align your product ("what") to your "why" — Start with the "why"
