Resource Capacity: refers to the total amount of work a team can achieve in a given time frame. It takes into account factors like individual team member skills, number of team members, availability (vacation, sick leave), and the number of productive hours in the workday.
Project Size: The size of the project refers to the amount of work that needs to be completed. This can be represented in a variety of ways including Story Points, Ideal Days, or Hours.
Velocity Metrics: Velocity refers to the amount of work completed during a certain time frame, typically represented by an Agile iteration or sprint. Velocity is expressed in the same units as project size (such as story points or hours).
Deciphering The Change Data
Effective utilization of changes in resource capacity, project size, and velocity metrics is not about static values but interpreting trends over time. It involves observing shifts in these data points to identify potential issues, improve estimation accuracy, and ultimately, enhance project outcomes.
Implementing Data in Estimating Completion
Continuous use of resource capacity, project size, and velocity metrics involves an iterative adaptation of the estimation process. These metrics provide a path towards refining estimates of how long project completion will take and what resources would be necessary.
For instance, let’s say a team has a resource capacity of 80 story points per sprint and has a project size of 240 story points. Based on these numbers, the project’s initial completion estimate would be three sprints. But after the first sprint, they find that their velocity was 60 story points, not 80.
Table: Velocity and Estimate Updates
| Sprint | Velocity | Remaining Story Points | Estimated Remaining Sprints |
|---|---|---|---|
| Sprint 1 | 60 | 180 (240-60) | 3 (180/60) |
| Sprint 2 | 70 | 110 (180-70) | 1.6 (110/70) |
| Sprint 3 | 75 | 35 (110-75) | 0.5 (35/70) |
By using these continuously updated estimates, the team can reforecast and better predict how long the project will actually take to complete.
Significance of Continuous Use of Data
The continuous use of resource capacity, project size, and velocity metrics is significant due to its potential to foster incremental improvement and enhanced accuracy in project completion estimates. By looking at trends over time, it enables Agile teams to become learning organizations, using their experiences to refine their future work.
Conclusion
In conclusion, the continuous use of project size, resource capacity, and velocity metrics allows Agile practitioners to respond more efficiently to changes, promoting more accurate representations of a team’s progress and more accurate predictions for product delivery estimates. This is an essential aspect of Agile project management and a key area of focus for the PMI-ACP exam.
Remember, estimating is not a one-time affair, but rather an ongoing process of adjustment, iteration, and refinement. By considering and applying these principles, Agile practitioners can not only increase the likelihood of timely project completion but also contribute to creating a sustainable and continuously improving Agile environment.

Interview Questions
How does data from changes in resource capacity affect the estimate to complete in agile project management?
Changes in resource capacity can significantly affect the estimate to complete. When resource capacity increases, the project could potentially be completed faster, leading to a decrease in the estimate to complete. Conversely, if resource capacity decreases, the project may take longer, leading to an increase in the estimate to complete.
What are velocity metrics in the context of agile project management?
Velocity metrics are used in agile project management to measure the amount of work a team can complete during a given time period, often known as a sprint. They are crucial in estimating time to completion and can meaningfully inform resource allocation.
Why is the size of the project significant when evaluating the estimate to complete?
The size of the project is significant because it determines the scope of the project. Larger projects inherently require more resources and time compared to smaller ones. Hence, changes in project size will alter the estimate to complete.
How can a PMI Agile Certified Practitioner use velocity metrics to evaluate the estimate to complete?
An Agile Practitioner can use velocity metrics by comparing the amount of work a team has completed in previous sprints to estimate how much work can be completed in future sprints. This can help to predict delivery dates and to evaluate the estimate to complete.
How can changes in resource capacity be calculated, and how is this useful?
Changes in resource capacity can be calculated by assessing the increase or decrease in available resources. This includes factors such as team size, available hours, and other resources such as technology. Recognizing these changes is useful for adjusting project timelines and managing stakeholder expectations.
What kind of effects can fluctuations in velocity metrics have on the completion of a project?
Fluctuations in velocity metrics can either extend or reduce the time for completion. A consistent decrease in velocity will likely result in a delay, whereas an increase in velocity might lead to early completion.
What is the purpose of regularly evaluating the estimate to complete in an agile project?
Regularly evaluating the estimate to complete allows for proactive management and adjustment of the project timeline, resource allocation, and scope. This ultimately aids in maintaining the quality of the project and meeting stakeholders’ expectations.
How does project size factor into changes in resource capacity?
Larger projects typically require more resources than smaller ones. If a project grows in size, this will correspondingly require an expansion in resource capacity. Similarly, if a project decreases in size, there might be surplus resources that can be allocated elsewhere.
How is the continuously updated data from changes in resource capacity and project size used in agile project management?
Updated data from changes in resource capacity and project size are crucial in recalibrating estimates and predictions, allowing for efficient resource allocation, schedule adjustments, and maintaining overall project control.
What strategies could be employed if velocity metrics show a consistent decrease?
If velocity metrics show a consistent decrease, strategies to address the issue could include re-evaluating the team’s workload and capacity, providing further training or support to the team, adjusting the project scope, or increasing resource allocation.
How can a PMI Agile Certified Practitioner effectively communicate changes in velocity metrics to stakeholders?
A PMI Agile Certified Practitioner can communicate velocity changes by using clear, simplified charts and graphs that depict changes over time, explaining its potential effect on the project timeline, and proposing actionable solutions to either mitigate delays or manage the early delivery.
What role does continuous monitoring and data collection play in agile project management?
Continuous monitoring and data collection play a crucial role in ensuring project milestones are being met, resources are effectively allocated, potential risks are flagged and managed, and the overall project is progressing as planned, ensuring predictability and control.
How can data on changes in resource capacity be used to manage stakeholder expectations?
Communicating data on changes in resource capacity to stakeholders contributes to transparency, helps manage their expectations, and can prevent potential misunderstandings or conflicts related to changes in project delivery dates.
How can an increase in project size alter the velocity of a project?
An increase in project size can decrease the velocity if the increase is not matched with proportional increases in resources. This creates a higher workload that can slow down the progress unless additional resources are allocated to maintain the velocity.
How can an Agile Practitioner maintain consistent velocity metrics?
An Agile Practitioner can maintain consistent velocity metrics through careful planning, ensuring that the team is not overcommitted, ensuring resource availability and capability, and providing necessary support and training to the team as required.
