Which of the following statements regarding PERT analysis is TRUE? Select one: O a. Project variance is the sum of all activity variances. O b. Project standard deviation is the sum of all critical activity standard deviations. O c. Each activity has two estimates of its duration. O d. Only critical activities contribute to the project variance

Give an explanation of how earned value management (EVM) may be used to keep expenses under control and monitor the overall effectiveness of a project, and then hypothesise as to why it is not utilised more often. How can one determine if the data for cost variation, schedule variance, cost performance index, and schedule performance index are healthy or unhealthy? What are some basic rules of thumb?

What are the main challenges and considerations in choosing an appropriate system modeling approach for a specific project?

We reduce Activity B to 4 weeks on each of the six houses.What affect will that have on the project completion time? Show work on the template provided. The x axis is the number of houses The y axis is time (number of weeks)

The chart below shows the initial investment and expected yearly payback for Project A and Project B     Project A Project B Initial Investment  $      300,000  $      450,000 Expected Yearly PayBack  $        45,000  $        90,000   For Project A, There has been a change in the expected yearly payback. Years 1 and 2 – you are expecting $45,000 each year. For the next three years, you are expecting $70,000 each year. What would be the average ROI for this alternative?

Consider the office renovation project data in the following table. A "zero" time estimate means that the activity could take a very small amount of time and should be treated as a numeric zero in the analysis. Click the icon to view the table. a. Based on the critical path, find the probability of completing the office renovation project by 40 days. Refer to the standard normal table. (Make sure to round all intermediate calculations for to and variance to two decimal places.) The probability is . (Enter your response rounded to four decimal places.)

How is quality control of a project different from quality control of a manufacturing process?

III. Risks and Feasibility This section of your report identifies risks and confirms the feasibility of the information systems development project. Project feasibility analysis verifies whether a project may be started and successfully completed. Your report should address the feasibility issues listed below. Start by clearly describing what issues are addressed by each feasibility category (see the relevant definitions in the textbook), and discuss the feasibility of the project with respect to each category. Determine organizational and cultural feasibility. This evaluates organizational and cultural issues to identify potential risks for the new system. See pp. 269–270 of the textbook for examples of potential issues.Note: the textbook does not provide an exhaustive list of possibilities!Note: ‘organization’ in this context refers to the Car Sharing community—all stakeholders, but particularly members and prospective members. Assess technological feasibility. See p. 270 of the…

Risk Management Questions    Using the criteria set forth in ISO 14971, complete the risk management evaluation for the following project. List at least 3 Harms in each category. Use the form attached to the test.   Johnson and Johnson is considering the development and marketing of a new wound care dressing (Zenorox). Zenerox is intended be used to stop bleeding and protect deep wounds up to 2 cm deep and 5 cm long. It incorporates a new clotting agent to help normal blood clotting action. Construction is a combination of synthetic polymers bound to a natural cotton fiber which carries the clotting agent. It also contains an antibiotic and wound healing acceleration agents. The product is supplied sterile for use by trained adults in an emergency situation. It can be used for up to 48 hours without changing Complete the Risk Management assessment per the attached template.   Use the risk table below     Risk table Max acceptable risk score =15   Max acceptable risk score…
