The CSI, as a one number, single dimension indicator offers very little value - it is not to say that a survey can use a methodology to deliver valuable measurements designed for specific actions. Given a body temperature measurement, doctor would have just a minor help in delivering correct diagnosis. Roy,

If the commenter is in fact a customer with little expertise, but the product or service is aimed squarely at a market of unskilled users, the commenter is exactly the right ruler. If by contrast the product or service assumes a level of familiarity or expertise which the the commenter lacks, it is the ruler that's being measured. The survey sample needs to be directed at the right target. There’s a missing variable: What is the target market of the product or service?
