Time Analysis Related Topics: Time Analysis Time analysis is the process of determining the overall schedule of a project by calculating start and finish dates for each activity in the project. When to Perform Time Analysis If you have selected the option to perform time analysis whenever data changes, you do not need to specifically perform time analysis, as Open Plan performs this calculation automatically. Time Analysis for Multiple Projects (Batch Mode) You can perform time analysis in Batch Mode, enabling you to run time analysis for multiple projects at one time. Automatic Time Analysis Open Plan includes an automatic mode that performs time analysis whenever you perform certain tasks. Early and Late Dates Time analysis calculates four dates for each activity in a project. Float Calculations In general, float is the number of time periods by which an activity can be delayed without affecting other activities in a project. Supplemental Activity Information In addition to early dates, late dates, and float, the time analysis function in Open Plan provides information about each activity in the project. Project and Subproject Information Review more details about project and subproject information. Time Analysis Rules and Conditions Review the rules and conditions on Time Analysis.
