• Understanding Data: Business users need to know what analyses will be performed when designing the warehouse. Lack of experience in business intelligence can hinder effective report envisioning.

• Testing: Ensuring 100% accuracy is critical to avoid detrimental decision-making based on erroneous data. Thorough testing requires considerable resources to validate data accuracy.

• Performance: Data warehouses must be appropriately designed to meet performance needs. Initial designs must provide a stable foundation for optimal functionality.
