Venture managers are chargeable for duties throughout each a part of a enterprise. They must schedule work, handle folks, handle budgets and wrangle expertise—simply to call a couple of.
In the event you needed to boil it down and outline the core perform of a mission supervisor in only one sentence, it might be one thing like, “Venture managers guarantee work is completed on time and inside price range.”
However how does a mission supervisor know whether or not a mission is inside schedule, or falling behind? They use a strong calculation that quantifies and measures mission progress known as schedule variance.
Schedule variance may be calculated manually, nevertheless it’s way more efficient to make use of mission administration software program in order that it could replace dynamically and alter in actual time because the mission progresses. With ProjectManager, you’ll be able to monitor deliberate versus precise information with Gantt charts, dashboards and studies so that you by no means fall behind.
What Is Schedule Variance?
Schedule variance (SV) is a calculation that measures whether or not a mission is on monitor by calculating precise progress in opposition to anticipated progress. Schedule variance permits mission managers to convey information into the dialog. As a substitute of claiming, “The mission is falling behind somewhat bit,” one might say, “The mission is 20 p.c behind the place it must be.”
Schedule Variance & Earned Worth Administration
Schedule variance is a key part of earned worth administration, a mission administration methodology that considers a mission’s schedule, scope and price range. Schedule variance is a metric that measures the distinction between earned worth and deliberate worth, which is often expressed in financial models, equivalent to {dollars}. It helps mission managers with progress updates.
Venture managers can use schedule variance to establish tendencies and make selections to maintain initiatives on monitor. For instance, schedule variance can be utilized to find out what number of sources stay and easy methods to greatest use them. Schedule variance can be used to speak with group members and promote optimistic suggestions.

The way to Calculate Schedule Variance
To calculate schedule variance, it’s essential to first calculate two vital earned worth administration (EVM) metrics, the budgeted price of labor scheduled (BCWS) and the budgeted price of labor carried out (BCWP). These will then be used within the schedule variance components.
Budgeted Price of Work Scheduled (BCWS)
Budgeted price of labor scheduled (BCWS), also called deliberate worth (PV), is the price of the work that’s anticipated to have been accomplished by a selected time limit inside a mission.
It helps mission managers examine deliberate progress in opposition to precise progress when it comes to price. BCWS is essential in earned worth administration (EVM) because it permits for the calculation of schedule variance (SV) and schedule efficiency index (SPI), one other EVM mission metric used to find out how nicely a mission group is maintaining with the mission schedule.
By monitoring BCWS, mission managers can establish schedule deviations early and take corrective actions equivalent to reallocating sources to make sure the mission stays on monitor. To calculate the BCWP merely comply with these steps:
- Establish the Price range at Completion (BAC): A time period utilized in EVM to discuss with the whole price range allotted for the completion of a mission.
- Break down the mission scope into duties: The scope of a mission refers back to the work to be performed, it must be damaged down into particular person duties or motion gadgets. A piece breakdown construction may help with this course of.
- Estimate Useful resource Necessities and Prices: As soon as mission duties are clearly recognized, then mission managers can start to plan what sources might be wanted after which estimate their prices.
- Calculate the BCWS: Primarily based on an estimation of the mission activity prices, the mission administration group can decide the BCWS for any date within the mission schedule by including up the prices of the duties that ought to have been accomplished by then.
Budgeted Price of Work Carried out (BCWP)
Budgeted Price of Work Carried out (BCWP), generally known as Earned Worth (EV), is a metric that signifies the price of the work that has already been accomplished.
By evaluating BCWP in opposition to BCWS and the Precise Price of Work Carried out (ACWP), mission administration groups can measure whether or not they have carried out the work that was deliberate to be accomplished as deliberate within the mission price range and mission schedule.
To calculate BCWP, comply with the identical course of defined to calculate BCWS and easily add the precise prices of the duties which were carried out thus far in a mission.
Schedule Variance Method
To calculate schedule variance, subtract the Budgeted Price of Work Scheduled (BCWS) from the Budgeted Price of Work Carried out (BCWP). All values used might be a financial determine (USD, GBP, and many others.). Right here’s the components:
BCWP – BCWS = SV
Generally you will note this components as EV – PV, nevertheless it means the identical factor: EV (Earned Worth) – PV (Deliberate Worth) = SV

Schedule Variance Instance
That can assist you totally perceive this calculation, let’s use an instance state of affairs and plug within the numbers. Let’s say you’re managing a mission that can final 20 days and the whole mission price range is $100,000.
On this instance, you’re 10 days (or 50%) into the mission, so you must have accomplished $50,000 (50% of complete price range) price of labor by this level. However, sadly, you’ve solely completed $25,000 of labor.
Here’s what it appears like while you plug the numbers into our schedule variance components:
BCWP ($25,000) – BCWS ($50,000) = SV (-$25,000)
Then, to specific schedule variance as a proportion, merely divide:
SV (-$25,000) / BCWS ($50,000) = -.5 or -50%
This determine tells you that your mission is 50% behind the place it must be right now. If the ensuing quantity is optimistic, then your mission is forward of schedule. If the schedule variance comes out as zero, then the mission is strictly the place it must be!

Earlier than with the ability to measure schedule variance, one should first construct a mission schedule. Get a head begin on that by downloading the free mission timeline template for Excel.
Add duties, dues dates and milestones on this free template when planning a mission. As soon as all that information has been added to the spreadsheet a timeline to the proper will mechanically be populated, displaying your entire mission.
Schedule Variance vs. Venture Variance
Variance is just the distinction between a knowledge set. Subsequently, as we’ve famous above, schedule variance is the hole between the deliberate progress and the precise mission’s progress. Venture variance is broader, in that it consists of schedule variance, but additionally price variance, scope variance and high quality variance.
Schedule Variance vs. Schedule Efficiency Index (SPI)
Schedule variance and schedule efficiency are associated, however they give attention to completely different elements of the mission. We’ve explored schedule variance, however schedule efficiency index is broader in scope. It encompasses metrics and indicators to evaluate how nicely the mission is adhering to its schedule. This gives a extra complete view of how the mission is progressing relative to its schedule.
Significance of Schedule Variance in Venture Administration
Realizing whether or not a mission is forward or delayed and over or beneath price range is a core duty of a mission supervisor. Venture managers are trusted by their groups and by their firms to remain answerable for initiatives due to the next causes:
- Venture supply impacts the underside line. If a mission is late, shoppers and inner stakeholders stand to lose financially. When this occurs, it threatens the popularity of the corporate—which might result in future losses!
- Disorganization impacts inner groups. If initiatives slide off the rails and delays occur typically, groups are more likely to lose morale and motivation. Groups are the happiest when their arduous work pays off on the finish of a mission. Nonetheless, when a mission stalls or by no means appears to complete, group members start to lose religion.
