Earned Value Management (EVM) Calculation Plugin

This plugin provides the function of calculating evm of projects . EVM can help you to track your project progress and its status and to forecast the future performance of the project.

Main features

• Calculate EVM
• Chart with EVM (PV,EV,AC)
• Forecast project end date
• Set the baseline
• Display unfinished issues

Additional options

• Explanation of EVM
• Chart with Project Performance (SPI,CPI,CR)
• Select past baseline
• Change the calculating basic date
• Change the level of the forecast

How to calculate EVM

The below are used for EVM.

• start date
• due date
• estimated time (If you set it as 0, you will not get PV, CV)
• spent time

If you input these into your project, it can help you to calculate both a single issue’s EVM and whole project’s one. PV: Dividing estimated time by the days (from start date to due date) to get daily workload EV: After issues are closed, you can get EV.

Example

(1) Create an issue with:

• start date: 2015/08/01
• due date: 2015/08/03
• estimated time: 24 hours

At that time, only PV is calculated. As you have not closed the issue yet, EV equals 0. PV: Dividing estimated time: 24hours by 3 days (from start date to due date)

EVM	8/1	8/2	8/3
PV	8	16	24
EV	0	0	0
AC	0	0	0

(2) Input your spent time.

8/1: 10.0hours 8/2: 6.0hours 8/3: 8.0hours

EVM	8/1	8/2	8/3
PV	8	16	24
EV	0	0	0
AC	10	16	24

(3) After finishing the issue, close it on 8/3. EV will be calculated on 8/3.

EVM	8/1	8/2	8/3
PV	8	16	24
EV	0	0	24
AC	10	16	24

Based on these data, EVM and chart are created.

Chart

3 types of charts can be displayed.

Main chart

Show PV,EV,AC with baseline.Display unclosed issues according to the baseline.

Performance chart

Show SPI,CPI,CR of the days involved with PV,EV,AC

Version chart

Show PV,EV,AC of every version in the issue

Baseline

If you set baseline, you can know easily how project divergence is and whether new task (issues) can be added by chart. In other words, you can see whether your estimated daily workload is over or not by chart. PV is based on your baseline. In addition, you can set calculation without baseline by options.
