“If possible, quantify the contribution the feature makes towards the business objectives, so that people can make scoping decisions on the basis of facts rather than emotions ([ref013]). Will a specific feature contribute roughly $1,000, $100,000, or $1,000,000 toward a business objective? When an executive requests a new feature that he thought of over the weekend, you can use quantitative analysis to help determine if adding it is the right business decision.”
