<ul><li> Slide 1 </li> <li> Project Development Scheduling and Probability of Completion </li> <li> Slide 2 </li> <li> Learning Objectives To define project Terminology To illustrate AOA and AON diagrams To calculate Project Duration, Critical Path, and slack To compute and interpret probability of completing a project for a specific time </li> <li> Slide 3 </li> <li> Project Networks A flow chart that graphically depicts the sequence, interdependencies, and start and finish times of the project job plan of activities that is the critical path through the network. Provides the basis for scheduling labor and equipment. Enhances communication among project participants. Provides an estimate of the projects duration. Provides a basis for budgeting cash flow. Identifies activities that are critical. Highlights activities that are critical and can not be delayed. Help managers get and stay on plan. </li> <li> Slide 4 </li> <li> Terminology Activity (task): an element of the project that requires time. Merge Activity: an activity that has two or more preceding activities on which it depends. Parallel (Concurrent) Activities: Activities that can occur independently and, if desired, not at the same time. A C DB </li> <li> Slide 5 </li> <li> Terminology continued Path: a sequence of connected, dependent activities. Critical path: the longest path through the activity network that allows for the completion of all project- related activities; C ABD </li> <li> Slide 6 </li> <li> Terminology continued Slack (or Float) The amount of time an activity can be delayed after the start of a longer parallel activity or activities. Total slack The amount of time an activity can be delayed without delaying the entire project. </li> <li> Slide 7 </li> <li> Terminology continued Event: a point in time when an activity is started or completed. It does not consume time. Burst Activity: an activity that has more than one activity immediately following it (more than one dependency arrow flowing from it). Two Approaches Activity-on-Node (AON) Uses a node to depict an activity. Activity-on-Arrow (AOA) Uses an arrow to depict an activity. B D A C </li> <li> Slide 8 </li> <li> CPM Critical Path Method was developed by Dupont. It is a deterministic model where time estimates are accurate and do not vary. A project is made up of a sequence of activities or tasks that form a network representing a project The path taking the longest time through this network of activities is called the "critical path". The critical path provides a wide range of scheduling information useful in managing a project. Critical Path Method (CPM) helps to identify the critical path(s) in the project networks. A network diagram is a graphic representation of the project and consists of directed arrows and nodes. To create a workable network diagram a project must have: well-defined jobs or tasks whose completion marks the end of the project; independent jobs or tasks; and tasks that follow a given sequence. </li> <li> Slide 9 </li> <li> Basic Rules to Follow in Developing Project Networks 1.Networks typically flow from left to right. 2.An activity cannot begin until all preceding connected activities are complete. 3.Arrows indicate precedence and flow and can cross over each other. 4.Each activity must have a unique identify number that is greater than any of its predecessor activities. (AOA) 5.Looping is not allowed. 6.Conditional statements are not allowed. </li> <li> Slide 10 </li> <li> Illogical Loop 610 FIGURE 6.10 </li> <li> Slide 11 </li> <li> Activity Relationships Activity Relationship AOAAON </li> <li> Slide 12 </li> <li> Activity Relationships S precedes T, which precedes U.
