Go/no-go
Go/no-go is the moment when the decision is made to proceed with a project, assignment, campaign or activity. Instead of deciding early on whether to proceed with a plan, it is first worked out in more detail. This allows all the details, including costs, opportunities and threats, to be worked out first.
Go/no-go is the point at which the final decision is made (usually by upper management) whether the plan can go forward. Before making this decision, the project is reviewed to see if it meets all the relevant requirements to go ahead and if there are no impeding objections.
When giving the green light we speak of a go, when withdrawing a plan we speak of a no-go.
