Differentiate between Purchaser and End User

When determining the user profile, make sure to differentiate between the purchaser or buyer of the product and the actual end user. Sometimes the user profile is slanted toward the person who makes the buying decision but who knows very lUtle about the problems that the end ujrs Le. Cprobablv would not want to bring in purchasers" to test the product; that wiU give vou a very slanted view of how the product is performing 

Another potential pitfall is the fact that the end user of the product and the end user of the documentation may differ. This is especially true for laree systems being developed for internal end users, where onlv one or two people such as the system administrator, will receive documentation. The rest of the end users will be left to their own devices or will have to ask specificallv for the documentation
