5. (10 points). True or False: One of the ways to reduce a project duration is to convert serial path to concurrent (parallel) paths when possible. a) True b) False 6. (10 points). Short answer: Please write one reason why the Budget Contingencies are needed in the project cost estimation. 7. (10 points). Estimate the total cost for the following scenario: There is a task that requires 5 workers. To complete the task, it usually takes 5 months, but want to add 20% more for the time buffer. Each worker's monthly salary is $6,000. Use 30% of direct cost per month as an indirect cost. 8. (10 points). Assume that there is a repeated task for project duration. Based on historical data, it takes 17 hours for the initial unit of output. The learning rate from the experience is 0.8. What is the time estimated for the Sth task? Use following formula. Show all your work to get a full credit. Yx=aXb Where : Yx= time required for the x unit of output a= time required for the initial unit of output X= the number of units to be produced b= learning curve slope =log( learning %)/log(2)
