Q 3. If a system is satisfying the needs of users, they will naturally make more use of the system. If not, the users will abandon the system, and a data warehousing system with no users is detrimental to Alpha 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 many users are 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
Alpha Technologies boasts an abundant stream of resources ready for deployment
