Rebaseline is the process of updating project baselines to reflect changes in scope, schedule, or resources.

• Rebaseline is necessary when there are significant changes in project scope or timelines.

• The process involves assessing current performance against the original baseline and determining new baseline metrics.

• Rebaseline should occur at critical project phases, such as after major scope changes or midway through the project.

• For example, if a project is delayed due to unfor...read more

Planned value and earned value are key metrics in project management, representing different aspects of project performance.

• Planned Value (PV) is the budgeted amount for work scheduled to be completed by a specific time.

• Earned Value (EV) is the budgeted amount for work actually completed by that same time.

• For example, if a project has a total budget of $100,000 and is scheduled to complete 50% of the work by month 6, the PV at month 6 is $50,000.

• If by month 6, the project has...read more

CPI and SPI are key performance indicators in project management, measuring cost efficiency and schedule adherence respectively.

• Cost Performance Index (CPI) = Earned Value (EV) / Actual Cost (AC). A CPI > 1 indicates cost efficiency.

• Example: If EV is $100,000 and AC is $80,000, then CPI = $100,000 / $80,000 = 1.25.

• Schedule Performance Index (SPI) = Earned Value (EV) / Planned Value (PV). An SPI > 1 indicates ahead of schedule.

• Example: If EV is $100,000 and PV is $120,000, the...read more
