Time Proportionality 

Use

This measurement technique is suitable for work packages where you are planning activities which cover the whole period of processing, such as consulting or administration.

Prerequisites

You must maintain the start and finish dates for the WBS element or activity:

For the Planned POC: Basic Dates

You maintain planned dates for WBS elements in date planning, the project planning board, or structure planning. These are the basic start and basic finish dates.

The system schedules the matching dates for the activities.

For the Actual POC: Actual Dates

The actual dates in WBS elements: Actual start and actual finish

The actual dates in activities are as follows:

You can either enter the actual dates yourself manually, or have the system determine them using confirmations.

Features

The system determines the duration using the:

In progress version customizing, you stipulate which set of dates the system should use to determine the POC:

The system assumes linear progress of the project over time. It determines the POC in proportion to the total project duration. Until a final confirmation is entered for the activity, the system adopts the planned overall duration as the actual overall duration.

The system uses the factory calendar to determine the duration. This means that the POC calculation takes account of events such as plant shutdowns. As a result, the POC for a particular period may increase only by an insignificant amount, or not at all.

Example

You have maintained the following dates for an activity:

Planning type

Basic start - basic finish

Date

01/25/99 - 04/16/99

This results in the following POC values:
