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.) b. Find the date by which you would be 80 percent sure of completing the project. Refer to the standard normal table. One is 80 percent sure the project will be complete in days.

John, Jack and Jill are project managers for Jusco Company. All three of them lead their own team, with two supervisors working under them. John’s team has 10 members, Jack has 8 members in his team and Jill has 11 members under his care. Both John and Jack completed their projects on time with the same amount of allocated budgets from top managers. But Jill didn’t manage to complete the project on time this time round. (i) Assuming all three projects have the same scale in terms of size, quality,and complexity, what can we conclude about the effectiveness and efficiency of these three project managers based on the informationabove? Justify your answers PLEASE PROVIDE CLEAR EXPLANATION THANK YOU , THIS TOPIC IS UNDER EVOLUTION OF FUNDAMENTAL MANAGEMENT THEORIES
B and C are incorrect.
The expected number of days to completion for a different project is E(x) = 3.32 The variance of days to completion is var(x) = 1.22 The project cost involves A fixed cost (in thousands of dollars) of FC = $83.783 A variable cost for each day taken to complete the project ($000) VC = $9.774 14 The expected value of the project cost is $_______ thousand. a 109.364 b 112.746 c 116.233 d 119.828
A recent IBM study of 585 mobile application developers and managers found that just one-third of mobile development projects matched budget, schedule, and objective requirements. In light of this, what are some dangers for organizations like FIMC who are developing and deploying a mobile app quickly?
A project has a critical path with an expected duration of 22 and variance of 14. What is the probability it will be completed within 20-25 weeks (inclusive)? (the range of the answers account for rounding errors) Group of answer choices Between 55% and 58% Between 17% and 20% Between 47% and 52% Between 64% and 67% Between 60% and 63%
(i) Project's standard deviation is the square root of the variance. Write a formula in cell F48 to compute the project's standard deviation.(j)The earliest finish time for the last activity is the Project's duration. Write a formula in cell F50 to compute the project's duration. (Hint: You have to only refer to the cell range)We would like to use the variance information to compute the probability that the entire project will be complete in 35 days. Screenshot attached thank you!! z
If it is necessary to crash to 250 or 240 days, how would Hill do so, and at what costs? As noted in the case, assume that optimistic time estimates can be used as crash times.
Article: Harry Hartfield was looking over some recent travel brochures while consulting his recent Google search. Retirement is only 5 days away and he could not wait to see the Fiji Islands. He and his wife thought they would start with a restful break before they started their travels in earnest.
