How many Agile velocities do you know?

Outcome of Velocity in Agile

Velocity is a key Agile metric that provides insights into a team's performance, efficiency, and predictability. The outcomes of tracking velocity include:

  1. Sprint Forecasting & Planning Helps teams predict how much work they can complete in future sprints. Enables Product Owners to prioritize backlog items effectively.
  2. Capacity Management Ensures teams do not overcommit or underutilize their capacity. Helps in balancing workloads to maintain sustainable delivery.
  3. Progress Tracking Provides visibility into team productivity over multiple sprints. Identifies trends, such as increasing or declining efficiency.
  4. Continuous Improvement Helps detect bottlenecks and inefficiencies. Drives process enhancements through retrospective discussions.
  5. Stakeholder Communication Gives stakeholders a data-driven way to set expectations. Supports better decision-making for release planning.
  6. Predictability in Delivery A stable velocity helps estimate how long a feature or project will take to complete. Reduces uncertainty in long-term planning.
  7. Identifying Risks & Dependencies Fluctuations in velocity highlight impediments or dependencies. Helps teams proactively address risks impacting delivery.

Example Outcome:

If a team's velocity has stabilized at 40 story points per sprint, the Product Owner can predict that a feature requiring 120 story points will likely take 3 sprints to complete. This enables better roadmap planning and stakeholder alignment.

Types of Velocity in Agile:

Velocity in Agile refers to the amount of work completed by a team in a sprint or iteration. It helps in forecasting and measuring productivity. The different types of velocity include:

  1. Planned Velocity – The estimated amount of work a team plans to complete in a sprint.
  2. Actual Velocity – The actual amount of work completed by the end of the sprint.
  3. Average Velocity – The average amount of work completed over multiple sprints.
  4. Sustainable Velocity – The work a team can consistently deliver over time without burnout.
  5. Ideal Velocity – A hypothetical best-case scenario where the team delivers at full capacity without blockers.
  6. Committed Velocity – The amount of work a team commits to delivering at the start of a sprint.


Purpose of Velocity & Improvement Parameters for Velocity:

Purpose of Velocity:

  1. Forecasting: Helps predict how much work can be completed in future sprints.
  2. Capacity Planning: Ensures teams take on a realistic workload.
  3. Performance Tracking: Identifies trends in productivity over time.
  4. Process Improvement: Helps in assessing efficiency and making data-driven decisions.

Improvement Parameters for Velocity:

Velocity improvement involves continuous monitoring and making changes to enhance efficiency. Some parameters include:

  1. Reducing Bottlenecks – Removing impediments to maintain a steady flow.
  2. Better User Story Sizing – Ensuring stories are well-refined and appropriately sized.
  3. Improving Collaboration – Enhancing team communication and engagement.
  4. Automation – Reducing manual efforts to save time.
  5. Technical Debt Reduction – Addressing technical issues proactively.

Example of Velocity Improvement:

Scenario: A Scrum team has an average velocity of 30 story points per sprint. However, in the last three sprints, the velocity dropped to 20 points due to unplanned work and unclear requirements.

Actions Taken for Improvement:

  • Refining backlog items more effectively before sprint planning.
  • Limiting Work in Progress (WIP) to reduce multitasking.
  • Automating repetitive tasks to free up time for development.
  • Conducting retrospectives with action items to improve sprint execution.

Outcome: The team's velocity increased back to 30+ points, showing improved efficiency.


When is Velocity Not Useful?

  1. For Comparing Teams – Different teams have different ways of estimating effort, making velocity unreliable for cross-team comparisons.
  2. When Teams are New – New teams need time to stabilize before velocity becomes meaningful.
  3. During Major Changes – Changes in team composition, processes, or technology can make past velocity data unreliable.
  4. In Unpredictable Environments – When frequent scope changes occur, velocity becomes inconsistent.
  5. When It Becomes a Target – If teams focus on improving velocity as a goal rather than delivering value, it can lead to gaming the system (e.g., inflating estimates).
