Time Periods

The time periods are used to specify resources for the architecture against a timeline indicating when they are expected to be in use. Time periods can be defined when the subjects, or resources, of the forecast, are already added to the table. As shown below, the Technology area column must be filled in with resources before adding a specific time period.

The Helicopter, Maritime Rescue Coordination Center Software, and Compas-Sarsat System Standard resources added in the Technology are as subjects for SV-9 table.

Time Periods Dialog

The Time Periods dialog is essential when defining time periods for the forecast of the resources.

The Time Periods dialog consists of three areas:

  • Toolbar - This area allows you to control how properties in the dialog are displayed: Categorized view, Alphabetical view, Expand all, Collapse all. 

  • Properties - Provides a list of properties that are available to specify.

  • Properties value cells - The fields where you can set values for each property.

Time Periods dialog

Due to the abundance of buttons in the dialog, the instructions are broken down into two parts: General instructions and Specific instructions. General instructions will explain how to open the Time Periods dialog and how to approach the main part of the Time Periods dialog: the Timeline. Specific instructions will explain how to specify Forecast Kinds in the dialog.
