Sin #3: Gluttony - Avoiding the 7 Deadly Sins of Windows 7
Gluttony: Migrating more than you need to by not cleaning things up first
Organizations often use an OS migration as a time to evaluate the applications, software and other data files they have on the organization’s existing endpoints. They can also use this time to plan their go-forward imaging standards. Those organizations that don’t go through this evaluation and planning process may be migrating more than is necessary (gluttony) once they begin the migration process.
One of the first critical decisions will be determining the specific deployment standards and processes to be used during the migration and, optimally, on a go-forward basis. This could be a considerable undertaking depending on the organization and their existing processes. For example, some IT departments may manage 30+ images that quickly become a logistical nightmare, draining time and resources away from other, more critical issues. However that same company may only need five images to accomplish what they need by balancing their imaging and application needs.
Deploying a standard hard disk image is the fastest and most consistent way to install a new operating system. As a best practice, keep images as small and generic as possible. Only include applications in the base image that must be installed on all computers, and install other applications in the same process, but separately from the OS image. Moving to Windows 7 is an opportunity to clean up and start fresh.
A key step in the migration process is to identify what applications will function on Windows 7 and what applications do not. This is essential for system stability, security and overall productivity. Since organizations often have hundreds of applications, categorizing the applications by rank (critical to not important) and type (commercial, legacy or custom) lays the foundation for testing priority. Start with business critical applications and work down to the least important. You can now map out a strategy for what updates or replacements are required. Organizations should also familiarize themselves with newer options, such as application virtualization, which might be appropriate for some applications.
By undertaking these steps organizations are starting on a path of considerable costs savings. Implementing standardized images improves the overall supportability of the end-user device. That translates to potentially fewer help-desk calls, easier troubleshooting and happier end-users. Subsequent automation of common IT processes, like hardware and software deployments, results in better use of IT resources. According to Gartner moving from a somewhat managed to well manage device may improve your desktop TCO by 30 percent. Your migration provides the opportunity to achieve it!
