Key recommendations from the report:
1. Refocus QA and Testing on customer
experience and business assurance.
2. Transform the traditional Test Center of
Excellence (TCOE) using agile and
DevOps practices.
3. Expand testing teams’ skills beyond
manual test towards test automation.
4. Prioritize testing with predictive
analytics and continuous feedback.

Intelligent BI testing makes BI testing fun and interesting. Able to detect defects much
earlier in the Data Flow chain. Helps them concentrate on the
critical functional areas of testing.
Reduces time taken by monotonous testing activities.
