How do you calculate activity variance?

PMP Formula: Variance of Activity

  1. = ((P – O) ÷ 6) ^ 2.
  2. = (Standard Deviation of the Activity) ^ 2.
  3. O = Optimistic Estimate.
  4. P = Pessimistic Estimate.

What is activity level variance?

Activity variances are the differences between the static/planning budget and the flexible budget and are caused by the difference between planned and actual activity levels.

What is the activity variance for sales?

Sales variance is the difference between actual sales and budget sales. It is used to measure the performance of a sales function, and/or analyze business results to better understand market conditions.

How do you find the activity variance along the critical path?

CP represents activity on critical path:

  1. Project duration expected E = 5 + 15 + 4 + 5 = 29 days (i.e. the total of te-s for activities on the Critical Path).
  2. Variance of the Critical Path = 2.79 + 2.79 + 0.45 + 0 = 6.03.
  3. Standard Deviation (SD) of project duration is √6.03 = 2.46.

What is the difference between free float and total float?

Total float, also called float or slack, is the amount of time an activity can be delayed without delaying the overall project duration. Free float is the amount of time an activity can be delayed without delaying the early start of any immediate successor activity.

How do you determine activity durations?

Under the three-point estimates procedures, the PERT (Program Evaluation and Review Technique) is the most broadly utilized statistical tool to decide the time duration of a project. In Project Management, the PERT technique is the best way to determine the estimated activity durations of a Project.

What type of activity is variance?

An activity variance is the difference between a revenue or cost item in the flexible budget and the same item in the static planning budget. An activity variance is due solely to the difference in the actual level of activity used in the flexible budget and the level of activity assumed in the planning budget.

What is actual activity level?

The activity level is the amount of an activity used by a cost object. The concept is employed in activity-based costing. If the activity level can be reduced, then activity costs should decline, thereby reducing the overall expenditure level of a business.

What are the 3 main sales variances?

They are:

  • Gross profit variance. This measures the ability of a business to generate a profit from its sales and manufacturing capabilities, including all fixed and variable production costs.
  • Contribution margin variance.
  • Operating profit variance.
  • Net profit variance.

What are the types of variance analysis?

Are used to represent activity in a network diagram?

Arrows are used to represent activity in a network diagram. Events are generally represented by circles.
