The evaluation of the Desktop Component (DTA) is an integral part of the overall office transformation model (DTM) providing clear guidance on how to turn "Wow" in "How." during this series of blog posts, I discussed the seven key phases that make up the DTA. We are now on the sixth stage of the series:
- Define business priorities
- Feedback app
- User Segmentation
- capacity Assessment
- high-level design
- transformation office Roadmap
- high-level project plan
After finishing the high level design, you will have a good overview of how everything fits together - including the logical architecture, more storage and hardware requirements. But be careful - do not make the mistake of jumping directly into the design and / implement all at once! It will be much more complicated than expected and it is important that you deal more than you can handle. Instead, treat each user group as a separate project and rank them according to their "Business Impact" and here are some thoughts to help you 'Time to Value'.
business impact. Consider the impact that desktop virtualization will have on each user group and rank them accordingly. It is important that you double back here, and use the business priorities identified in step 1 to make sure that you assign an appropriate classification. Do not assign ratings based on how highly the company values each user group - which focuses on user groups offer the most benefit to the company after virtualization . There is a subtle but important difference.
value time. For each user group, estimate how long it will take to implement the model FlexCast selected based on the results of the capacity assessment. For example, you may find that a company already has a XenApp farm that can be leveraged to support the user groups who need a hosted shared desktop resulting in a low time value. Otherwise, the company may have no prior experience with XenClient and a laptop area of aging that is not on the HCL XenClient resulting in a long time to value. Compare application sets, user needs and the number of users during differentiation between user groups that have been assigned the same model FlexCast.
One of the best practices I use is to complete the table below in the ranking process to make sure I capture all key information:
key to creating your desktop transformation roadmap is to give priority to groups of users so that the company gets the maximum benefit from their investment as soon as possible. The best way to visualize this and to ensure that you have the order came to trace the user groups on a graph of time Vale / Business Impact:
in my next post I will run through the last stage in the evaluation of the office processing - high-level project plan. That's where we define the key tasks necessary for the implementation of each project group of users and to provide estimates of time and planning. That should keep him happy project manager
