Demystifying the S-Curve in Project Management: A Brief Guide
The S-curve is an important concept in project management. This brief guide will explain what an S-curve is, the different types of S-curves, how to create and use an S-curve, and the common uses for S-curves in project management. Understanding S-curves can help a project manager make better decisions and keep a project on schedule and budget.
An S-curve is a mathematical graph that tracks cumulative data for a project over time. It is called an "S-curve" because of its S-like shape. The beginning of the curve has a slow, gradual slope as the project ramps up. In the middle is a steep curve upward as the project is in full swing. Toward the end, the curve starts to flatten out as growth slows when the project nears completion.
There are two main types of S-curves used in project management - the baseline S-curve and the actual S-curve. The baseline S-curve represents the original project schedule and budget. It shows the planned progress over the project life cycle. The actual S-curve uses real-time cumulative data to track the actual progress and costs incurred during the project life cycle. Comparing the actual S-curve to the baseline S-curve helps project managers determine if the project is on track.
How Do You Create an S-Curve for a Project?
To create an s-curve, you first need to determine what cumulative data you want to track for the project. Common elements to track with s-curves include:
Budget - Track cumulative costs over time
Schedule - Track cumulative progress towards milestones
Labor - Track cumulative man-hours put into the project
Scope - Track percentage of scope completed
Risks - Track number of risks closed out
Deliverables - Track percentage of deliverables completed
Once you determine what you want to track, you then plot the cumulative values at regular intervals over the timeline of the project. For example, you may plot cumulative costs on a weekly or monthly basis. Connect the plotted data points to see the s-curve form.
When creating the baseline s-curve, you use the planned estimates from the project schedule and budget. For the actual s-curve, you plot cumulative actual data as the project progresses. Comparing the actual s-curve versus the baseline shows whether the project is on track.
What Are Some Common Uses for S-Curves in Project Management?
There are many ways s-curves can help project managers:
Track Overall Project Progress
Comparing the actual s-curve versus the baseline s-curve shows whether the overall project is on schedule and budget. Any deviations or variances become highly visible. Project managers can identify and investigate issues early.
Monitor Specific Project Elements
S-curves can be created for any measurable project element - cost, schedule, scope, quality, etc. By honing in on specific elements, issues can be identified at a granular level. For example, a schedule s-curve may reveal a critical path delay even if the overall project s-curve looks fine.
Identify Trends
The slope and shape of the s-curve reveals the rate of growth and productivity. For example, a flattening slope may indicate a loss of momentum and potential problems. Or an unusually steep curve may represent unsustainably rapid progress.
Forecast Completion
Using the baseline as a reference, the s-curve can be extrapolated to estimate the final cost or completion date. The actual s-curve provides leading indicators for the likely outcome.
Plan Resource Allocation
The curve shows periods of rapid growth that require more resources. It also reveals times when demand will decrease. This helps optimize budgeting and staffing.
Assess Risks
Variances, unusual slopes, and odd data points may represent potential risks. S-curves help identify areas that require further risk analysis and management planning.
Identify Milestones
Major milestones and deliverables show up as distinct inflection points on the s-curve with rapid changes in slope. This highlights key events for tracking and celebration.
Communicate Status
The s-curve provides an intuitive, graphical status indicator for stakeholders. Trends and issues are easily digested.
What Does the Shape of the S-Curve Tell You?
The overall shape and slope of the s-curve gives visual insight into the health and performance of a project:
Slow Start
A gradual slope at the start of the project is normal as the team ramps up and gets organized. Some projects also have regulatory delays or approval gates at the start that constrain progress.
Steep Slope
The steepest part of the curve indicates when the project team is working at peak capacity during the build/delivery phase. Maximum resources are needed here. Budget and staffing should align to this demand.
Inflection Points
Changes in the slope indicate milestones being met or phases transitioning. Planning should ensure sufficient resources are available for each ramp up to prevent bottlenecks.
Flattening Curve
As the curve flattens, it signals the project is winding down. Growth is slowing and work is being completed. Projects that flatten prematurely may need to reconfirm scope and objectives.
Below Baseline
If the actual curve falls below the baseline, it likely indicates the project is behind schedule or over budget. The project manager needs to investigate root causes of the deviation.
Above Baseline
Exceeding the baseline may represent a potential risk of unsustainable overperformance. Reconfirm reasons for being ahead of schedule and ensure quality is not compromised.
When Would You Plot a New S-Curve?
There are scenarios where significant changes require creating a new version of the s-curve:
Major Scope Changes
If the project scope increases or decreases substantially, the original s-curve is no longer valid. New estimates must be created for the revised scope.
New Project Phase
For multi-phase projects, it's common to reset the s-curve at the start of each new phase or stage gate. This accounts for the new planning estimates.
Revised Estimates
If estimates change significantly, the original s-curve baseline becomes outdated. Recalculate based on new estimates.
Schedule Delays
Delays shift the planned s-curve right on the timeline. Capture revised timing in a new baselined s-curve.
Performance Issues
If the project has major performance problems, a reset may be required. Re-planning the project will produce a new s-curve.
The new s-curve then serves as the baseline for comparing actual values moving forward. By rebaselining periodically, the s-curve remains relevant as a project evolves.
S-Curve Variations
While ideal s-curve models show a smooth S-shape, real projects may exhibit different curve characteristics:
Delayed Start
It's common for project ramp up to be slower than planned initially. This right-shifts the s-curve.
Discontinuous
A large gap between project phases can create a disjointed s-curve rather than smooth progression.
Accelerated Slope
Some projects have an s-curve with a steeper than planned slope due to aggressive execution or underestimation.
Jumps and Spikes
External factors like contract awards or materials delivery may cause jumps in the curve rather than steady progress.
Skewed Left
Frontloading more effort skews the curve left - bulk of work done early in the project.
Skewed Right
Backloading work skews the curve right - majority of work occurs late in the project life cycle.
Compressed
Accelerated timelines can horizontally compress the s-curve by squeezing activities together.
Limitations of S-Curves
While useful, s-curves also have limitations to be aware of:
Data Accuracy - The quality of the s-curve depends on the accuracy of the cumulative data used to plot it. "Garbage in, garbage out."
Static View - S-curves provide snapshots in time. To be meaningful, they must be refreshed with new data points as the project progresses.
Lack of Detail - The high-level curve smooths out and hides nuances in performance data. Need to dig deeper into specifics.
Predictiveness - While directional, s-curves estimate future performance but cannot predict unknowns.
Variable Shapes - Real projects may substantially deviate from a theoretically perfect s-curve shape.
To mitigate these limitations, use s-curves in combination with detailed performance data, financial reports, risk plans, and other PM artifacts. Think of s-curves as supplemental decision-making tools.
Tips for Using S-Curves Effectively
Here are some tips for getting maximum value from s-curves:
Select Metrics Carefully - Only plot data that truly represents project progress. Avoid "false" indicators.
Set Realistic Baselines - Initial s-curve plans are only helpful if based on accurate estimations.
Update Frequently - Add new data points regularly to detect issues in a timely manner. Monthly or bi-weekly is recommended.
Look for Patterns - Step back to identify trends, inflection points, outlier data points, and anomalies.
Standardize Scales - Use consistent s-curve scales and intervals for easier trend analysis across projects.
Combine Tools - Use s-curves together with project schedules, budgets, risks, and financials for integrated project oversight.
Communicate Status - Share updated s-curves with stakeholders periodically to align on project status and prevent surprises.
Track Risks - Monitor s-curve deviations which may indicate emerging issues or risks requiring mitigation.
Key Things to Remember About S-Curves
In summary, key things to know about using s-curves in project management:
S-curves graph cumulative data over time to visualize project progress and trends.
They enable tracking status, surfacing issues, forecasting completion, and planning resourcing.
Compare actual s-curves to a baseline plan to identify deviations.
The slope at different points indicates the rate of progress.
Milestones create distinct inflection points on the curve.
Major changes may require rebaselining and plotting a new s-curve.
Analyze patterns, trends, and odd data points on the curve.
Use s-curves with detailed schedules, financials, risks, and other PM tools.
S-curves are relatively simple to create but powerful when applied properly.
Conclusion
S-curves bring valuable visualization to project progress and early indicators of performance. When combined with detailed project data, they are an invaluable tool for project managers seeking tight oversight and control. Mastering when and how to apply s-curves takes practice, but it enables better forecasting, resource planning, and risk management. While not a crystal ball, s-curves can demystify project status and provide a path to success if leveraged fully. This brief guide summarizes the key basics around s-curves, but there is always more depth to explore for those seeking project management mastery.
