I am inspecting the BI delivery methods in my company looking for new efficient ways. We are working in the traditional "water flow" methods were requirements being translated by development to ETL packages, testers translate it there way to some SQL script and compare both results of the SQL scripts and the package.
Seems to me that instead of writing the same solution twice it is better to have one process of close cooperation between development and testing using the same platform, methods and tool.
I am looking for a new methodology, examples of similar implementation in other companies.
Thanks for your help
