Common Pitfalls
Common pitfalls are those concerning creating and understanding the data model that is used, i.e. ensuring the source of the data is trustworthy and has integrity, that it represents the operational activities of the organization and provides accurate reporting. Taking time to plan and create the data model is key.
Training staff who will use the system to create reports is key and is often over-looked. Staff must understand the data model and how the system works and fits together so that accurate, reliable reports can be created.
Other pitfalls are those common to any technology implementation: ensure that it aligns with the organization's goals, objectives, and processes; involve users in the definition and creation of the data model and system.
