Answer to Question 1

Unlike the initial version, in subsequent versions not all requirements will be collected from scratch. Original requirements provide the starting point for additions and alterations. Many of the additions and modifications result from observations and feedback by the end users during the use of the previous version, indicating the ways in which the data warehouse can be improved or expanded. Other new requirements may stem from changes in the operational data sources or changes in underlying technology.
