Sprint Retrospective

Introduction

What are some ways to improve your scrum process? As a sprint wraps, retrospectives often become an overlooked chapter of closure, which can lead to repeated mistakes and missed opportunities for future growth. Our Sprint Retrospective toolbox covers topics from project performance to team morale, and provides methods to conduct structured, thoughtful retrospectives such as the 4L, STAR, and Sailboat to identify improvement opportunities and eliminate waste. As the sprint team actively engages in feedback and recommendations in the process, the retrospective can bring forth better collaboration, more quality deliveries, and more accurate planning for future sprints.

On an organizational level, the consistent practice of sprint retrospectives nurtures and strengthens an agile and lean culture. This can result in products better built for customer satisfaction, sustained project efficiency, and optimized team productivity across the board.

Sprint performance analysis

Defect leakage

Analyses of defect leakage shares insights into the quality of the work delivered by the sprint team. A high defect leakage rate indicates that testing processes within the sprint are insufficient or that defects are not adequately addressed. Understanding these leaks allows teams to improve the quality assurance process, so that more robust testing and defect resolution can be performed before reaching the end-user. Reduction in defect leakage not only improves customer satisfaction, but also lowers the time and cost associated with fixing defects post-sprint.

Effort estimation variance

Effort estimation variance refers to the gap between the estimated effort to complete tasks and the actual effort expended. This data reveals the accuracy of initial workload prediction and whether adjustments are necessary to refine future estimates. As these issues get addressed, teams can improve sprint predictability and size tasks more appropriately. Consistent and accurate effort estimation builds confidence for team members as they are able to better complete tasks with the right allocation of resources and time. 

Sprint performance comparison

Comparison of current sprint performance to historical sprint data gauges improvement or decline in metrics like team velocity, velocity trends, and variance between sprints. This provides a broader view of the team's long-term performance and reveals patterns that might not be visible in a single sprint analysis. This analysis acts as a foundation for data-driven improvements, building on the insights gained from defect leakage and effort estimation.

Team mood and morale

Team mood distribution

A chart that tracks mood distribution on a scale from "bad" to "excellent" over the sprint period shares a visual representation of team sentiment. With this chart, teams can identify patterns in mood fluctuations and connect them to specific events, workloads, or challenges that took place during the sprint.

Recurring dips in mood at certain points could signal a consistent source of stress, such as a particular task or deadline pressure. Conversely, spikes in positive mood might align with successful sprint outcomes, effective collaboration, or lighter workloads. These trends allows teams to recognize morale issues before they escalate, leading to more engaged, motivated, and productive collaborations.

"What used your energy?"

Another aspect to team wellbeing is the energy drain that each member experiences throughout the sprint. Using a scale that ranges from "recharged energy" to "completely drained," this metric looks into how different tasks, challenges, or sprint activities impact individual and collective energy levels.

Identifying sources of energy depletion helps teams reallocate resources, redesign workflows, or adjust sprint goals to better match its capacity. On the other hand, tasks or moments that recharged the team's energy provide clues about what motivates and energizes the team, so future sprints might be organized to re-introduce these positive aspects.

Retrospective techniques and exercises

4Ls framework

The 4Ls framework encourages team members to reflect on

• What they enjoyed – "Liked"
• What new knowledge they gained – "Learned"
• What they felt was missing – "Lacked"
• What they wish for in future sprints – "Long for"

With these four dimensions, teams can reach a balanced understanding of both strengths and areas for improvement. This team-wide exercise thrives on open, transparency communication and helps teams surface underlying issues. The spirit is to reinforce positive practices and proactively address known challenges.

STAR retrospective

The STAR guides teams toward actionable insights by focusing on five key areas. This structure facilitates a balanced evaluation of both areas of strength and weakness. With that in mind, teams can craft actionable plans that promote continuous improvement. 

• "Keep going" – highlights practices that are working well and should be maintained in future sprints.
• "Do more of" – identifies positive actions or behaviors that, while present, could have an even greater impact with increased emphasis.
• "Start doing" – encourages the team to adopt new practices or approaches that could enhance sprint performance.
• "Stop doing" – calls out unproductive activities or processes that are hindering progress.
• "Do less of" – asks the team to reduce the frequency or intensity of practices that may be helpful in moderation but are currently overused.

"Waste snake"

​​The waste snake exercise maps out inefficiencies and unnecessary processes, which can weigh down productivity. By identifying "waste" – such as redundant meetings, bottlenecks, or miscommunications – the team can streamline its workflow and focus on value-adding activities and reduce non-value activities. As teams work to remove inefficiencies, they can shift their focus to more creative and forward-looking exercises.

"Genie in a bottle"

The "Genie in a Bottle" technique introduces a more whimsical element by asking team members to imagine they have three wishes to improve their work process or the sprint itself. This exercise encourages the team to think outside the box and bring new ideas to the surface that may not arise in more conventional frameworks. The insights gained from these team "wishes" often reveals core frustrations or unrealized opportunities for improvement.

Sailboat retrospective

The sailboat retrospective is a metaphorical technique that helps teams reflect on their sprint journey by considering the elements that either propel them forward or hold them back. Each element, as outlined below, influences the team's progress:

• Wind – represents the driving forces that push the team toward their goal. These are the strengths, enablers, or positive factors that helped the team succeed during the sprint.
• Sun – symbolizes the elements that provide energy and motivation to the team.
• Land –  is the destination or the sprint goal the team is striving to reach. It represents the project's objectives or deliverables. If the land feels distant or unclear, it prompts a discussion on whether sprint goals were well defined and attainable.
• Shark – represents the dangers or risks that threaten to derail the team's progress. These can be unforeseen obstacles or external factors that could cause the sprint to fail if not managed properly.
• Anchor – symbolizes what holds the team back or slows down progress. These could be inefficiencies, bottlenecks, or unresolved issues that acted as barriers.

Scrum values retrospective

The scrum values retrospective focuses on the five core values of scrum: commitment, courage, focus, openness, and respect. By reflecting on how well these values were upheld during the sprint, teams can assess their alignment with agile principles. This exercise emphasizes the importance of team culture and collaboration. A strong foundation in these values ensures that all the other techniques and exercises, from 4Ls to the sailboat retrospective, are carried out with the right spirit.

Conclusion

Sprint retrospectives, when properly conducted, drive continuous improvement by harnessing the power of collection team reflection. With the application of retrospective exercises like the 4Ls, STAR, sailboat, teams benefit from boosted collaboration, increased efficiency, and enhanced overall performance, all laying the groundwork for long-term agile success.
