What is BAU testing ?

[John]

Hi, Can somebody please elaborate the 'BAU(Business As Usual) Testing. As far as I know, check for bugs in application during the testing phase or once the application has been released for production (Product Support Testing)

The only time I have heard this term used was referring to minor patches, enhancements, and configuration changes after a system was put into production.

I think it's a silly term, but apparently it is meant to convey a sense of continuity through low-risk changes.
