Assignment Content

1. A project plan outlines recommended approaches to the use of the network, database management system, software, and cloud service technologies. Because industry best practices dictate transparency in terms of selection criteria and their importance to a specific project, a project plan draft should also include the criteria by which the recommended approaches were selected, along with the benefits to the project that each is expected to deliver.

   For this assignment, you will draft a project plan for the project proposal you outlined in Week 1 (and that you updated earlier this week based on instructor feedback).

   Download the Project Plan Draft.

   Using the Project Plan Draft template, outline your project plan for the business scenario that was approved by your instructor last week. Add lines to each table as needed. Your project plan will include:

   • Network technology recommendation(s)
   • Database management system recommendation(s)
   • Appropriate software application recommendation(s)
   • Cloud service recommendation(s)
