Method and system for assessing the progress of a project in terms of its schedule
The invention describes a computer-implemented method and system for assessing the progress of a project in terms of its schedule. The method includes receiving project data and based on the project data, calculating a first period (PE) after which a current earned value (EV) was expected to be realized. The method also includes calculating a second period (PR) in which the current EV has been realized. Further, the method includes calculating a fraction component (EF) of a period when the current EV was expected to be realized and finally, calculating an earned schedule performance index (ESPI) based on PE, PR and EF, wherein the ESPI indicates whether the project is on schedule.
1. A computer-implemented method for assessing the progress of a project in terms of its schedule, the method comprising:
i. receiving project data from a database; and
ii. based on the received project data, calculating by a processor:
a first period (PE) after which a current earned value (EV) was expected to be realized, the first period being calculated in terms of a predefined unit of time;
a second period (PR) in which the current EV has been realized, the second period being calculated in terms of the predefined unit of time;
a fraction component (EF) of a period when the current EV was expected to be realized, wherein the EF is calculated as: EF=(EV−PVp)/(PVw−PVp), wherein EV is the earned value, PVp is the previous planned value associated with a period immediately preceding the one in which the current EV was expected to be realized, and PVw is the planned value of the period in which the current EV was expected to be realized; and
an earned schedule performance index (ESPI) based on PE, PR, and EF, wherein the ESPI indicates whether the project is on schedule.
2. The method as recited in claim 1 , wherein the PE is calculated as: PE=SDp−START+1, wherein SDp is a status date associated with a previous planned value (PVp) and START is the start date of the project.
3. The method as recited in claim 1 , wherein the PR is calculated as: PR=SD−START+1, wherein SD is a status date of current status report and START is the start date of the project.
4. The method as recited in claim 1 , wherein the ESPI is calculated as: ESPI=(EF+PE)/PR.
5. The method as recited in claim 1 , wherein the predefined unit of time comprises months, weeks, days, hours, minutes and seconds.
6. A system for assessing the progress of a project, the system comprising:
i. a database for storing project data; and
ii. a processor for calculating, based on the stored project data:
a first period (PE) after which a current earned value (EV) was expected to be realized, the first period being calculated in terms of a predefined unit of time;
a second period (PR) in which the current EV has been realized, the second period being calculated in terms of the predefined unit of time;
a fraction component (EF) of a period when the current EV was expected to be realized, wherein the EF is calculated as: EF=(EV−PVp)/(PVw−PVp), wherein EV is the earned value, PVp is the previous planned value associated with a period immediately preceding the one in which the current EV was expected to be realized, and PVw is the planned value of the period in which the current EV was expected to be realized; and
an earned schedule performance index (ESPI) based on PE, PR and EF, wherein the ESPI indicates whether the project is on schedule.
7. The system as recited in claim 6 , wherein the processor calculates the PE as: PE=SDp−START+1, wherein SDp is a status date associated with a previous planned value (PVp) and START is the start date of the project.
8. The system as recited in claim 6 , wherein the processor calculates the PR as: PR=SD−START+1, wherein SD is a status date of current status report and START is the start date of the project.
9. The system as recited in claim 6 , wherein the processor calculates the ESPI as: ESPI=(EF+PE)/PR.
10. The system as recited in claim 6 , wherein the predefined unit of time comprises months, weeks, days, hours, minutes and seconds.
11. The system as recited in claim 6 , further comprising a storage module for storing at least calculated values of PE, PR, EF and ESPI.
12. The system as recited in claim 6 , further comprising a reporting module for generating reports based on calculated values of PE, PR, EF and ESPI.
