Within the context of project and program management, variance analysis is a strategic process that allows managers to assess performance by comparing actual results with forecasted or planned values. As part of the Program Management Professional (PgMP) exam, it is crucial to understand and apply different analytical techniques to identify variances and trends in costs, schedule, quality, and risks. By performing this analysis, project managers can identify necessary corrective actions or potential opportunities.
Identifying Variances in Cost, Schedule, and Quality
Cost variance (CV) and schedule variance (SV) are two important types of variances that project managers often analyze. The CV allows program managers to understand the financial status of a project, whether it’s under or over budget. The SV helps in assessing the project’s progress against its planned schedule.
For instance, if the actual cost (AC) of a project is $200,000, and the budgeted cost of work performed (BCWP) or earned value (EV) is $150,000, the cost variance (CV) would be -$50,000. This indicates that the project is running over budget.
On the other hand, if the actual time spent on a project is 5 months and the planned schedule was 4 months, the schedule variance (SV) would be negative (-1 month). This indicates that the project is behind schedule.
It’s equally important to analyze the variance in quality. If the actual quality of deliverables is not meeting the planned quality, it may cause customer dissatisfaction, leading to project failure.
Analyzing Trends in Risk
Along with cost, schedule, and quality, it’s critical to analyze risk variances. The risk management process includes identifying, evaluating, and managing the uncertainty of a project. By comparing the actual risk (AR) experiences against the planned risk (PR), managers can identify whether the existing risk management strategies are effective and apply corrective actions if required.
For example, if a project has a risk of data breach, the actual occurrence of this breach would indicate an increased risk variance. If the actual risk is higher than the planned risk, then program managers need to reassess their risk management strategies.
Corrective Actions and Opportunities
Once the variances are identified, the next step for the program manager is to implement corrective actions to address any discrepancies between the plan and actual accomplishment. If the project is overbudget, cost-cutting measures may be introduced. If the project is behind schedule, additional resources could be allocated to catch up.
Opportunities uncovered during the analysis might include cost savings, improved timelines due to enhanced processes, or increased benefits identified through proper risk management. These opportunities can significantly contribute to project success.
Table for Revision
To visualize this data, you may find it useful to create a table. Below is an example:
| Parameters | Planned Values | Actual Values | Variance | Corrective Actions |
|---|---|---|---|---|
| Cost | $150,000 | $200,000 | -$50,000 | Implement cost-cutting measures |
| Schedule | 4 months | 5 months | -1 month | Allocate additional resources |
| Quality | High | Moderate | Deterioration | Examine process for inefficiencies |
| Risks | Data breach possibility accounted | Real data breach happened | Increased risk variance | Reassess risk management strategies |
Remember, the goal of variance and trend analysis is not only to understand where the project stands compared to its initial plan but also to identify potential issues and correct them proactively. This ensures the ultimate success of the project and is a key skill tested in the Program Management Professional (PgMP) Exam.
