Discussion Instructions

For this discussion, consider the following scenario:

Sally is the project manager for a mid-sized publishing firm. She is currently working on a project that involves a complete Windows upgrade for her organization. All of the organization’s PCs are being upgraded with Windows 7 and all of the servers are being migrated to Windows 2008. Halfway through the upgrade, Sally is ahead of schedule and under budget when she discovers that there is a compatibility issue with several major printers throughout the organization. With research, she finds that 64-bit drivers are not available for the printers the organization currently owns.

Use the discussion resources and your own research to discuss the following:

Explain the network engineering life cycle and identify the stage in which Sally made her error.

Discuss ways that Sally can now rectify her mistake in planning without jeopardizing both the schedule and the budget.

If you were Sally’s superior, discuss what you would do in response to this potentially serious situation with a high-visibility project.

Discussion Instructions

For this discussion, consider the following scenario:

Ken has been hired as the project manager at a local hospital and is in charge of implementing a new electronic health record system, which was designed in India. He discovers that the network staff woefully underestimated the impact of the application on the available bandwidth of the network. The poor response time of the application now threatens the user acceptance of the software. Ken must present a change request to senior management for a network upgrade that will put the project over budget and behind schedule by thousands of dollars and several weeks.

To further complicate the matter, the network manager is a member of senior management and is expected to argue vociferously that his staff was not properly informed, thus not in a position to provide accurate information to the project team.

Use the resources provided as well as your own research to support your discussion of the following:

Describe some techniques and strategies that can be used to maintain high availability on a network.

Offer some suggestions on how Ken can help senior management accept the need for additional funding without fracturing his relationship with the network manager.

Explain how you would handle cultural issues with the overseas developers of the application.

Discussion Instructions

Use the resources provided and your own research to complete this discussion.

While mapping data for the wireless network architecture in a large mature organization, you encounter duplication of effort and redundant data.

Discuss whether the redundant data should be addressed prior to beginning the wireless network architecture project, in coordination with the network architecture project, or after the project has been completed.

Provide a supported rationale for your choice.

What strategy would you use to maintain security of data within a wireless infrastructure? Why?

Be sure you correctly cite any references you use according to APA guidelines.

Discussion Instructions

For this discussion, consider the following scenario:

The CIO of the organization for which you are developing your project network decides after seeing the data flow maps you created that the timing is right to alter their relationship with their primary supplier. Currently, inventory requirements are maintained by the organization and orders are placed over the phone. The CIO would like to give the supplier a direct connection into the organization’s inventory system and make them responsible for maintaining stock.

Use the resources provided as well as your own research to support your discussion of the following:

Explain the pros and cons of making this kind of change as part of the development of a secure network infrastructure. How would you support or dispute this request for change in the project scope, and address the ethical standards and implications of this decision?

Describe 2–3 enterprise network management tools (for example, HP OpenView, Entuity) that you have used. Would you recommend using them to manage the network for the vendor relationship?

Be sure you correctly cite any references you use according to APA guidelines.
