Schedule Variance =

((Actual Duration - Planned Duration)/Planned Duration)*100

Effort Variance =

((Actual Effort - Planned Effort)/planned effort) *100

HI Naseem,

Here you have given the formula for Effort variance is (Actual - Planned Effort)/ Planned Effort or (Actual - Estimated) Estimated effort) Can you pls tel which is right? I would like to what is the difference between planned and the estimated effort. Is it right insted of plan if we use stimated.

Kindly explian the reason - Email id is rvs.svr@gmail.com

Planned Effort is the actual estimate you received from the Client. If you do your own estimate based on the planned effort you get from the client then that will be a different scenario.

Variance is the difference between the plan and actual. It could be anything
(budget, schedule, effort, resources, scope, quality, performance - any
measurable item in a project that we can plan for). It can be a zero, positive
or a negative variance. While positive variance means bad planning, a zero
variance or negative variance could mean good planning. However, too much of
negative variance (over 10%) could mean bad planning as well.

Consider the following.
Planned budget - \$10 Million
Actual Cost at completion - \$11 Million
Budget Variance – Actual – Planned = \$11 Million - \$10 Million = \$1 Million
(Project is Over by \$1 million – bad planning, bad budget management)

Planned budget - \$10 Million
Actual Cost at completion - \$9.5 Million
Budget Variance – Actual – Planned = \$9.5 Million - \$10 Million = -\$0.5 Million
(Project is under budget by \$500 K, good planning and effective project
management)

Planned budget - \$10 Million
Actual Cost at completion - \$5 Million
Budget Variance – Actual – Planned = \$5 Million - \$10 Million = -\$5 Million
(Project is grossly under budget, by 50%. Bad planning and bad management – the
project planner grossly overestimated the project and locked up \$5 Million of
the company’s money that could have been better spent elsewhere).

Effort Variance= (Actual effort-estimated effort)/Estimated effort*100

Schedule Variance=(Actual elapsed time- estimated elapsed time)/estimated elapsed time*100

Effort Variance should be (Actual Effort - planned Effort)/ Planned Effort.

EV should calculate w.r.t Person Days.

Schedule variance should be (Actual End Date - Planned End Date)/Planned End Date.

SV should calculate w.r.t Person Hours.
