If the system is satisfying user needs, users will naturally use the system. If not, users will abandon the system, and a data warehousing system with no users is actually a detriment to beck technologies (since resources that can be deployed elsewhere are needed to maintain the system). Therefore, it is very important to have a tracking mechanism to figure out how much/degree of usage by users accessing the data warehouse. This should not be a problem if:

    • Third-party reporting/OLAP tools are used, since they all contain this component

    • The right data warehousing investment is made

    • All users are compelled to use the system

    • The beck’s boast an abundant stream of resources ready for deployment
