In late 2008, we were experiencing an average of about 5,500 “blue screen” system crashes in our client environment per week. As a result, users were not satisfied with the stability of their PCs.
In order to improve it, we implemented a proactive problem management process based on analysis of objective, largely system-generated data from client PCs across our worldwide environment. Using this approach, we have increased client stability by reducing the number of blue screen system crashes by more than 50 percent, and we are beginning to realize benefits in other areas including unexpected shutdown and boot time.
The solution has two aspects – one is the business process based on Information Technology Infrastructure Library (ITIL). The 2nd aspect is based on collecting exceptions from the clients’ environment.
As the client’s environment is very rich and changes constantly,
it is very important to identify in advance what are the exceptions that impacts customer experience. Blue screens for example were identified as something that customers don’t like (no big surprise there I guess).
Once we start collecting the data and analyze it, we could identify trends and the main root because, that then we can fix in the entire client environment (see the banner on page 4, on the left).
Another approach to it was to recall Top N customers with faulty systems to the support center, which was a nice surprise to those customers realizing that IT knows that they have stability issues and fix it without them needing to raise an incident ticket.
From my experience, the main contribution to the change of the trend to reduce blue screens from 5,500 a week to 2,000 a week is doing a proper problem management and release solutions to the whole client environment. Fixing specific system one-by-one is not enough when managing so many systems.
Updating drivers across the enterprise usually did the job, and we focused on the ones we found to cause most of the blue screens.
The success indicator is the trend-down graph showing the decrease in the weekly blue screens count - this enables us to review progress, set goals and know if we’re on the right track - see below screen shot of the trend.
Key to these efforts are partnership across IT teams, indicators in place to measure and show progress and an execution plan that eventually improved customers’ experience from their client systems.
