Data Warehousing - Quality Assurance




Data Warehousing > Data Warehouse Design > Quality Assurance

Task Description

Once the development team declares that everything is ready for further testing, the QA team takes over. The QA team is always from the client. Usually the QA team members will know little about data warehousing, and some of them may even resent the need to have to learn another tool or tools. This makes the QA process a tricky one.

Sometimes the QA process is overlooked. On my very first data warehousing project, the project team worked very hard to get everything ready for Phase 1, and everyone thought that we had met the deadline. There was one mistake, though, the project managers failed to recognize that it is necessary to go through the client QA process before the project can go into production. As a result, it took five extra months to bring the project to production (the original development time had been only 2 1/2 months).

Time Requirement

1 - 4 weeks.

Deliverables

  • QA Test Plan
  • QA verification that the data warehousing system is ready to go to production

Possible Pitfalls

As mentioned above, usually the QA team members know little about data warehousing, and some of them may even resent the need to have to learn another tool or tools. Make sure the QA team members get enough education so that they can complete the testing themselves.
