Unit 8 Discussion ForumDiscussion Forum (suggested level of effort: 1 hour)The purpose of a discussion forum is for students to engage one another over topics related to the course material. An initial post by each student "sets the table" for follow-on responses by other students. In a graduate-level academic setting, the initial post is more than describing opinion by the student. Rather, it is opinion supported by published literature or other references (e.g., refereed journals, textbooks, and especially the PMBOK). The response post can be less formal but no less thoughtful in content.Discussion Topic: Activity Development and Problems with Estimating Activity DurationInitial Post Requirement (20 points): Minimum 300 words. There are 2 parts to the initial discussion post.Part 1: Think of at one thing you must do this week. For each part of the five parts of the definition of an activity described in Section 8.1, CPM4e, describe how it does or does not meet the definition.Part 2: Describe at least one activity needed to complete a work package in a project you’ve participated in the past. Using Exhibit 8.9, CPM 4e, discuss how you or your organization uses various remedies to address problems in estimating activity duration.Response Post Requirement (10 points): Minimum 150 words. In the response post, discuss how your organization addresses the problem described in Part 2 of the initial post. You can rely entirely on your experience or it can be a combination of your experience supplemented with information learned from the course reading materials and other references.Assessment: You will be assessed on 1) content and 2) completeness (e.g., use of in-text citation of references used for summarizing, paraphrasing and quoting and other writing mechanics) and word count.Note : i will send the peer student initial post to respond it.Unit 8 Individual AssignmentIndividual Assignment (suggested level of effort: 3.5 hours)There are 2 parts to this assignment. You can submit two files to the drop box. MS Project (should you have your own license to the software) is not acceptable for completing any part of this assignment.Part 1 Exercise Questions (40 points)Complete exercise questions 1 (5 pts), 3 (5 pts), 5 (10 pts), 6 (5 pts) and 9 (15 pts) found at the end of Chapter 8.Part 2 Scheduling Problem (50 points)Complete the following:Your child is a member of the school theater group and have been asked to prepare the schedule, etc. for a skit to be performed during the 4th of July celebration in the local village square. As a volunteer, you offer to serve as the project controller because of your expertise in schedule management.Construct an AON diagram similar to the format used in the Youtube videos found in the commentary using an MS Excel spreadsheet. Ensure that you include a Start activity and a Finish activity. Include a legend (example is the one completed in Question 1, Part 1.Calculate the estimated time for each activity using PERT techniques for the 3 estimates provided. Include a sample calculation.Prepare a table that identifies all paths and their lengths. Which path is the critical path?During the execution phase of the skit project, one of the activities on the critical path is delayed by one day. Is this serious?Using the activity estimates for optimistic, pessimistic and most likely time to complete activities on the critical path, qualitatively discuss the estimate uncertainty of the critical path.ActivityPredecessorTime (days)OptimisticMost LikelyPessimistic1None2462None5553235741710135111121362,4567739101183,65799479111053331171517191286810139,1078151471214161512,13161718You will be assessed on content and mechanics.Content (90 points): Each element of this assignment has a correct answer. Your content will be assessed on whether or not you produced a correct diagram, estimate, result, etc. or the degree to how you demonstrate knowledge of scheduling practices in case your diagram, estimate or result are incorrect.Mechanics (10 points): The results must include sample calculations (where applicable) and be presented in a professional manner. This is not an academic paper, therefore you do not need to follow APA guidelines. Your Instructor will use Turn-it-in to ensure your paper is authentic work. To avoid plagiarism, see the course home page for more information and use the Purdue Online Writing Lab to learn how to paraphrase, summarize and cite the references you use in all academic writing assignments.

Many towns and small cities have Web sites that they use to interact with their citizens. Describe three departments that should be included on the home page of a small town’s Web site and describe the citizen interactions that should be facilitated by the site for each department. If you were designing the 
web site – what else would you include? Give examples of how it would benefit the community and its members.
 The post should be 75 to 150 words

Capacity PlanningWord DocumentIntroductionYou are in the DevOps group at a government agency where the organization runs a case management application. They are having performance problems running the application in-house (a web server in their own data center), and there is too much downtime. They are looking to your advice about whether they need to procure one or more new web servers (Dell) or they should move to a cloud service. There are about 1200 concurrent users on the application each day, most of them at remote locations.Details of the application The application has a major web interface with a menu allowing the user to create a new case, update a case, find a specific case, or search for a case by a variety of terms.Main MenuThe current front-end application requires 0.5 GB of memory to run each instance and each instance can handle a maximum of 300 concurrent users.New Cases20% of the users create a new case when they access the system. The “new case” component calls 4 different services to collect different parts of the required information. Each service is called sequentially so only 1 service is in memory at any one time. The new case component stays in memory and takes 1.2 GB of memory. The maximum load it can take is 150 users. The maximum size of each of the services called is 0.5 GB and it can handle 50 users at the same time.Update CasesAbout 30% of the users are simply updating one or more of the pages created as above. Again,the component has 4 different services representing each of the different parts of the information. As above, each service is called sequentially so only 1 service is in memory at only one time.The “update case” component stays in memory and takes 0.75 GB of memory. The maximum load it can take is 300 users. The maximum size of each of the services called is 0.4GB and it can handle 300 users at one time.Find Specific Case About 30% of the users merely use the application to retrieve data on a specific case. The component is a stand-alone application. The maximum load is 80 users and the size of the component is 0.5 GB of memory. Search Cases The remaining 20% of users are performing searches to identify one or more relevant cases. The search system has a service to handle each of the five different search terms (e.g. topic, name, location, date, and prosecution status).Searches can involve 2 of these topics at the same time so 2 service instance can be in memory at the same time. The search case outer module stays in memory (1.5GB) and so does 2 of the 5 services (0.4 MB) each. The module and services have maximum local factor of 100 users.Non-Functional ConsiderationsDowntime has been a factor so the government organization wants to have at least 2 different VMs or servers. Each VM/server must have enough memory to carry the entire load in the case of failure of one of the machines (e.g., a hard disk failure).Memo Draw a component diagram of the application making for each module the number of instance that are necessary to adequately support the estimated workload.Prepare a spreadsheet identifying the various component memory requirements and calculate the total memory requirements, allowing for the multiple instances necessary to support the anticipated concurrent users.Prepare a memo to the CIO (Elizabeth Jones) with a copy to the CFO (Nathan Andrews) which summarizes the features of the 2 options, including the time it might take to provision them.Include information on the urgency of the requests as the inspector general will be doing an audit in 3 months’ time.In the last paragraph detail your recommendation, attached a spreadsheet showing your calculations, and the component diagram.Notes:In addition, the application requires a Registry/Load Balancer and this is a 1.2 GB application and should be in memory at all times.The application will require about 3 TB of data and has a service to retrieve data for each part of the system which requires 2GB of memory. It has capacity of handling 600 users.You may recommend the cloud service of your choice but your memo should justify why you selected the cloud provider, there should be at least 3 justifications.
