It further assumes that an activity can be completed in a shorter time by deploying additional resources or by adopting an alternate process, method or a skill-set at an extra cost. Project schedule links resources,tasks and time line together. You were given the assignment for you to learn. Successful Project Management, 2011: 57. Crashing shortens the project duration by assigning more resources to one or more of the critical tasks. Which activity should be the next activity crashed to cut a second day from the project's duration; how much is added to project cost? Bechtel's competitive advantage is supply chain management. The critical path is A-B-C, duration 13.
On a specific project, there can be multiple critical paths, all with exactly the same duration. The late start of an activity is its late finish less its duration. The late finish is the earliest of the late start times of all successor activities. Some activities on the critical path may have slack. C is completed before B.
All of the above are false. Identify the activities on the critical path. A network consists of the following list. Pessimistic time estimate is an estimate of the minimum time an activity will require. Some activities on the critical path may have slack.
The Critical Path also calculated using the 3 estimation time information given a long with Early Time, Late Time, Early Finish, Late Finish, slack and standard deviation. Any activity can be crashed if the duration of time can be reduced by adding resources additional labor, materials, etc. Gantt charts give a timeline and precedence relationships for each activity of a project. F's late start is 26. Get homework help and answers to your toughest questions in biology, chemistry, physics, math, calculus, engineering, accounting, English, writing help, business, humanities, and more. The late start of an activity is its late finish less its duration.
Both a and c are true 34. M is critical and has zero slack. Describe some of the challenges faced in the construction of the new 11-story building at Arnold Palmer Hospital in Orlando, Florida. Further, large variances on noncritical tasks need to be monitored. Predicts the time required to complete the project. Correct Answer: the weighted average of a, m, and b, with m weighted 4 times as heavily as a and b. The pasta products start in the mixing department, where durum flour, eggs, and water are mixed to form dough.
Gantt charts use the four standard spines of Methods, Materials, Manpower, and Machinery. There can be multiple critical paths on the same project, all with different durations. Activity details are in the table below. The method therefore assumes that the time and cost of the activity are decided by the resources and methodologies adopted for its performance and the relationships between time, cost and resources are known and controllable. If activity I were delayed by ten time units, what would be the impact on the project duration? Before beginning the project management process, you have to identify the most important task. Which of the following statements regarding Gantt charts is true? A project does not have to have a critical path. Every network has exactly one critical path.
On a specific project, there can be multiple critical paths, all with exactly the same duration. Activity details are in the table below. Pessimistic time estimate is an estimate of the minimum time an activity will require. The sum of all activity variances is 81; the sum of variances along the critical path is 64. Optimistic time estimate is an estimate of the minimum time an activity will require. E is an immediate predecessor of F.
Crashing a project often reduces the length of long-duration, but noncritical, activities. What are the three phases of a project? All of the above are true. Project standard deviation is the sum of all critical activity standard deviations. Which activities form the critical path? Crashing a project reduces the length of critical activities only. S is a critical activity. Question 19 Which scheduling technique should be employed when due dates are important for a job order? Describe each in a sentence or two. The dough is kneaded, rolled flat, and cut into fettucine or lasagna noodles, then.
