Forecast Class Page for the Percent Complete Ranges Method of the New Class Wizard

Use the options and fields on this page when selecting the Percent Complete Ranges method.

Contents

Field Description
Forecast method Select the Percent Complete Ranges method.
Forecast Dates Specify whether the forecast spread will be based on early, late, or default forecast dates. The early and late dates are used for best- and worst-case forecast scenarios.
Performance factor level This field controls the level at which Cobra calculates the CPI and SPI.
  • Levels 1-20

    The levels represent the hierarchical structure of a code file. Selecting a level instructs Cobra to perform forecast calculation at that level for the selected code file.

  • Project
  • Control Account
  • Work Package

    This field displays if you select one of the following forecast methods:

    • PF=1/CPI Cumulative to date
    • PF=1/CPI for current period
    • PF=1/CPI for last 3 periods
    • PF=1/CPI for last 6 periods
    • PF=User input
    • PF=1/(a*CPI+b*SPI)
    • Percent complete ranges
Code File

This field displays if you select any of the levels from 1 to 20 in the Performance factor level field. Use this field to select a code file to calculate forecasts against.

Percent Complete Ranges

Field Description
Percent Complete Ranges Enter range values to instruct Cobra to calculate the performance factor according to the amount of work completed.

You can specify up to four ranges over which a particular forecast method takes effect. You cannot enter values directly in the first four rows of the first column of the Percent Complete Ranges section. Use the second column to enter the percentages. Cobra automatically adjusts the starting percentages in the first column as you enter percentages in the second column.  

The value of the last row in the second column always equals 100%. You cannot enter a percentage value directly in this row.

Range Forecast Method Use the Range Forecast Method drop-down lists to select the statistical forecast methods that you want to use for the percent complete ranges. The performance factor (PF) level defaults to the PF level used on the forecast class if you select one of the following options on the Range Forecast Method drop-down lists:
  • PF=1/CPI Cumulative to date
  • PF=1/CPI for current period
  • PF=1/CPI for last 3 periods
  • PF=1/CPI for last 6 periods
  • PF=User input
  • PF=1/(a*CPI+b*SPI)
  • PF=1/(CPI*SPI)
