I have a quote that I personally heard in a meeting at the time I was a contractor at GE: The green check marks mean nothing! The quote itself maybe isn't too descriptive, so here's some background: Our team's work was dependent on another team's progress, and so they maintained a progress indicator to know what parts they finished working on. Our team didn't progress very fast, because we encountered a lot of little problems in the parts that were marked 'done' by the other team, and our manager kept nagging us about missing deadlines. After we explained the situation enough times to our managers, they called a meeting with the other team's managers. After 15 minutes of manager-talk, the other team's leader finally said the above quote that would end the meeting almost immediately.
