## Lesson Summary

* In project management, a schedule is a listing of a project's milestones, activities, and deliverables, usually with intended start and finish dates. Those items are often estimated by other information included in the project schedule of resource allocation, budget, task duration, and linkages of dependencies and scheduled events. A schedule is commonly used in the project planning and project portfolio management parts of project management.
* Milestones are tools used in project management to mark specific points along a project timeline. These points may signal anchors such as a project start and end date, a need for external review or input and budget checks, among others. In many instances, milestones do not impact project duration. Instead, they focus on major progress points that must be reached to achieve success.
* A Gantt chart is a type of bar chart that illustrates a project schedule. This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. The width of the horizontal bars in the graph show the duration of each activity. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements constitute the work breakdown structure of the project.
* Sequencing activities are usually used by scheduling dependencies. A dependency is a logical relationship with is a dependency between two activities or between an activity and a milestone. There are 4 standard types of dependencies; Finish to Start, Finish to Finish, Start to Start, Start to Finish.
* Graphical Evaluation and Review Technique, commonly known as GERT, is a network analysis technique used in project management that allows probabilistic treatment both network logic and estimation of activity duration.
* Critical Path Method (CPM) is an algorithm for scheduling a set of project activities. The model should include a list of all activities required to complete the project, the time each activity will take, the dependencies between activities, and logical end points, such as milestones of deliverable items. CPM calculates the longest path of planned activities.
* Arrow diagramming method (ADM) is a network diagramming technique in which activities are represented by arrows. Precedence relationships between activities are represented by circles connected by one or more arrows. The length of the arrow represents the duration of the relevant activity. ADM only shows finish-to-start relationships, meaning that each activity is completed before the successor activity starts.
* Precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies.
* Critical chain method (CCM) is a technique based on network changes project schedule taking into account scarce resources.
* Program Evaluation and Review Technique (PERT) is a network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates. PERT uses probabilistic time estimates – duration estimates based on using optimistic, most likely, and pessimistic estimates of activity durations – instead of one specific or discrete duration estimate, as CPM does.
* To use PERT, you calculate a weighted average for the duration estimate of each project activity using the following formula:
         * PERT weight average = (O + 4M + P)/6
         * (O) - Optimistic time, (M) - most likely time, (P) - pessimistic time
* As part of schedule development, project managers may establish quality gates, which provide acceptance criteria to ensure that project tasks are completing deliverables within the quality control guidelines established during project planning.
* A governance gate is similar to a quality gate in that it marks acceptance criteria for the project tasks, but a governance gate is more about client sign-off, management approval, or legislative approval. A governance gate should be set up whenever the project manager must obtain formal approval prior to proceeding with the project activities.

## Key Terms
### ADM (Arrow Diagramming Method)

    A network diagramming technique in which activities are represented by arrows. ADM is also known as the activity-on-arrow (AOA) method.

### CCM (Critical Chain Method)

    A technique based on network changes project schedule taking into account scarce resources.

### CPM (Critical Path Method)

    A method commonly used with all forms of projects, including construction, aerospace and defense, software development, research projects, product development, engineering, and plant maintenance, among others. Any project with interdependent activities can apply this method of mathematical analysis.

### Gantt Chart

### GERT (Graphical Evaluation and Review Technique)

    A network analysis technique used in project management that allows probabilistic treatment both network logic and estimation of activity duration.

### Governance Gate

    This should be set up whenever the project manager must obtain formal approval prior to proceeding with the project activities.

### Milestone

    A tool used in project management to mark specific points along a project timeline. These points may signal anchors such as a project start and end date, a need for external review or input and budget checks, among others. In many instances, milestones do not impact project duration. Instead, they focus on major progress points that must be reached to achieve success.

### PDM (Precedence Diagram Method)

    The precedence diagram method (PDM) is a tool for scheduling activities in a project plan. It is a method of constructing a project schedule network diagram that uses boxes, referred to as nodes, to represent activities and connects them with arrows that show the dependencies. It is also called the activity-on-node (AON) method.

### PERT (Program Evaluation and Review Technique)

    A network analysis technique used to estimate project duration when there is a high degree of uncertainty about the individual activity duration estimates.

### Quality Gates
