Startup Performance & App Reliability
The question it answers: Which devices boot slowly or crash, and which applications crash or hang most across the fleet?
Which devices take longest from power-on to a usable desktop, which crash (blue screens), and which applications crash or hang most across the fleet. Slow and crashing devices generate helpdesk tickets; the model breakdown is the business case for replacing them.
