Problem as stated
Ahead of Black Friday and the holiday season, the client was moving to the latest MS Dynamics 365 release. That release carried performance fixes for outages in a prior year. The client had also recently added Azure integration services to its ERP environment. It wanted assurance that the changed system would hold peak trading volumes and leave capacity for future growth. [ev-1224]

Reading notes for a buyer
This case speaks to the scenario “Peak-season readiness in 90 days” and feeds dimension D3 (Peak-season and performance evidence) of the methodology. A question to put to Qualitest:
Which channels were tested, and did the client's live Black Friday traffic stay within the response times and order rate you tested? [ev-1224]
