Ken Costa shares this advice: In the theatre of war, when an officer has to make a snap decision, it is made using the “go-no-go” formula; in an instant, the factors for and against are calculated. If two-thirds align positively, it’s “go,” and if not, it’s “no-go.” Ken says: This may seem a crude calculation, but I have found it a useful tool.
