Introduction
In traditional business environments, workers suffer from productivity loss in many ways, including
downtime during PC refreshes, patches and updates, or simply when they are away from the office.
Application and desktop virtualization centralizes apps and desktops in the datacenter, rather than on local
devices. This allows IT to deliver apps and desktops to users on demand, to any device, anywhere.
Take the following response from a desktop virtualization user:
 
Unfortunately, organizations sometimes struggle to achieve this level of success. Why does one
organization succeed while another organization struggles?
If we compare the factors between success and failure between desktop virtualization and other
technology related projects, we see that there is little difference:
1.  Lack of justification – Without a solid business reason, desktop virtualization is simply a new way to
deliver a desktop. A business justification gives the project team a goal to strive towards.  
2.  Lack of a methodology – Many people who try and struggle to deploy a desktop virtualization
solution do so because they jump right in without understanding or implementing the
appropriate prerequisites. A structured methodology provides the path for the project.  
3.  Lack of experience – For many who embark on a desktop virtualization project, there is a lack of
experience, which creates a lack of confidence in the design. Architects begin to second-guess
themselves and the project stalls.  
Our hope is that this handbook can alleviate the anxiety associated with desktop virtualization by showing
how challenges can be resolved in a manner that is technically sound, but also feasible and effective for
organizations facing deadlines and other organizational challenges.
Citrix has successfully employed the methodology, experience and best practices shared within this
handbook across thousands of desktop virtualization projects.
