Tactical, Operational & Strategic Analysis of Markets, Competitors & Industries
I am currently working on a project to ascertain methods to validate human sources of information in intelligence. We are often faced with assigning a "reliability score" for our primary sources and more often than not go with our gut feel. When the two competing primary sources are clearly distinct - for example: the product manager in charge of the product line under investigation versus a junior level sales person, we intuitively know whom to trust. But when such distinction is not clear cut it becomes a little difficult.
Do you face this issue at work? If so how does one go about it? Are there any methods available? If you are aware of any published literature (books / articles) which deals with this subject do point me to them.. any help would be greatly appreciated.
