Somewhere at Microsoft some bean counters decided that formal QA was costing them too much and “agile” was a perfect excuse to scuttle QA (move fast and break things.) It’s bullshit that has been propagated throughout the software industry. “Well, Microsoft doesn’t do it this way anymore so...”. I work for an MS partner and this is exactly what’s happening in-house here. You’re just making your customers the beta testers.
