In order to calculate the timing of an activity ‘Duration’ of the activity needs to be summed up with the ‘Earliest Finish…

Our text book mentioned some of the critical success factors when scheduling. Some of these factors are when attempting to reduce the duration of a path activities that has a negative slack, focus on activities that are near term and activities that have long estimated duration, the person who will be responsible for performing the activity should approximate duration for that activity, the key to effective schedule control is address any paths with negative or deteriorating slack values aggressively as soon as they are identified, and activity estimated duration should be yet realistic (Gido & Clements, 5th Ed, pg 180). Based on the factors above, the schedule should be revised to find activities with negative slack and timing interval. For example, recruiting & training, create building design estimated duration time could be adjusted to shorter period. This will cause the earliest start and earliest finish time of other activities around these tasks to be adjusted and hence it might create some positive slack time. The Gantt chat also reveals that during the…
I a. Construct a network for the project. [pic] Slack or Float = LF – EF or LST – EST Activities on the critical path have zero slack/float. b. Calculate the scheduled completion time and identify the critical path.…
7) Refer to the figure. Suppose that additional resources are provided to crash the project completion time below its expected normal completion time. Which activities would be potential…
How can I identify which project activities are “critical” and which ones have “slack”? How do you confidently estimate a project duration when nothing similar has been done before? How can I determine the cheapest way to “speed up” a project?…
I Step 1: Construct a network diagram for the project. Step 2: Answer the following questions: (15 points total) a) Calculate the scheduled completion time. (5 points) 30 days b) Identify the critical path (6 points) BCDFH = 30 Days c) What is the slack time (float) for activity A? (1 points)…
Intense global competition and rapid technological advances create pressure on developing projects rapidly. This is an example of reducing project duration caused by:…
Project Management Activities: Planning-Objectives Resources Work Break-down Structure Organization Scheduling- Project Activities, Start & End Times, Activity Network Controlling-Monitor, Compare, Revise, Action Work Breakdown Structure: WBS is a hierarchical decomposition of the project into phases, deliverables and work packages. 1.Project 2. Major Tasks in the project 3. Subtasks in the major tasks 4.Activities (or “work packages”) to be completed Project Controlling: Close monitoring of Resources, Costs, Quality, Budgets. Feedback enables revising the Project Plan and Shift Resources. Computerized tools produce extensive reports Six Steps PERT & CPM: 1. Define the Project and prepare the Work Breakdown Structure 2. Develop relationships among the activities - decide which activities must precede and which must follow others 3. Draw the network connecting all of the activities 4. Assign Time and/or Cost Estimates to each activity 5. Compute the longest time path through the network – this is called the Critical Path 6. Use the network to help Plan, Schedule, Monitor, and Control the project Perform a Critical Path Analysis: The Critical Path is the Longest Path Through the Network…

Executive Summary The basic concepts of project management calls for proper planning, organization and the management of a variety of resources in order to successfully achieve a certain goal. One of the most important objectives of project management is the ability to deliver a product or service within a certain time constraint or “on time” as well as being fiduciary responsible or “within budget.” Thus, it can be seen that good project management makes efficient use of time, money, personnel, materials and supplies, and methods of communication in order to successfully complete a project. Unfortunately, these basic methods of project management were not…
