 Sprint 5 {{ref>fig:sprint5}} was originally scheduled to end earlier, but the team extended it by two days for two reasons: a vacation period fell near the original end date, and the new end date was aligned with the scheduled meeting with the teachers, giving the team additional time to prepare for the Interim Report presentation. The sprint started with a commitment of 32 story points, which grew to 33.5 after TRAQ-164 ("Table of power budget", 1.5 pts) was added to scope on the first day. The team closed out 21.5 points across 7 work items, including the report hand-in itself (TRAQ-155), the Interim Report (TRAQ-20, 10 pts), Schematics Version 3, the Website, the Application Prototype, and Retrospective 5. TRAQ-88 ("Chapter Project Management", 12 pts) remained in progress and carried over to Sprint 6. The burndown tracked below the ideal guideline through most of the sprint, with the steepest drop between April 8–10 as the interim report deliverables were finalized. Sprint 5 {{ref>fig:sprint5}} was originally scheduled to end earlier, but the team extended it by two days for two reasons: a vacation period fell near the original end date, and the new end date was aligned with the scheduled meeting with the teachers, giving the team additional time to prepare for the Interim Report presentation.

 Sprint {{ref>fig:sprint6}} displayed the most extreme "late-crunch" pattern of the project so far. The remaining work stayed flat at the initial commitment of 40 story points until April 20th, with the entire burndown collapsing into a 2-day window between April 22nd and April 24th. The team closed 24.5 points across 9 work items, including the 3D model video (TRAQ-21, 8 pts), the report fixes following interim feedback (TRAQ-168, 8 pts), the leaflet, the poster, the smart system schematics review, the video addition, the lab parts check, three daily meetings, and Retrospective 6. TRAQ-88 ("Chapter Project Management", 12 pts) remained in progress as expected — this item is intentionally kept open across sprints since new content is added to it on every cycle, and it will only be closed at the end of the project. The flat-then-cliff burndown shape reflects the team prioritizing deep work on the larger report and design items before logging completions in a single batch near the end of the sprint, rather than a true delivery delay. Sprint {{ref>fig:sprint6}} displayed the most extreme "late-crunch" pattern of the project so far.

 +
 +The burndown opened at roughly 40 story points and stayed flat until April 20. Almost all progress was logged in a single batch around April 23, dropping the remaining work to about 15 points — meaning the team closed roughly 25 points but finished above the ideal guideline, with the rest (chiefly TRAQ-88) carried into the next sprint.

 The Sprint that is shown in figure {{ref>fig:sprint7}} was the shortest sprint so far at one week, a tighter cadence following the interim report milestone. The sprint started with a commitment of approximately 23 story points. The burndown once again exhibited the team's characteristic "late-crunch" pattern: remaining work stayed flat from April 23rd through April 27th, dropped by a small amount on April 27th, then plateaued again before the bulk of completions were logged on the final day, April 30th. By the end of the sprint window shown, roughly 9 points had been burned down, leaving approximately 14 points still in progress at the time of capture. As in previous sprints, TRAQ-88 ("Chapter Project Management") is expected to remain open by design, since content continues to be added to it across every sprint and will only close at the end of the project. The Sprint that is shown in figure {{ref>fig:sprint7}} was the shortest sprint so far at one week, a tighter cadence following the interim report milestone.

 +With an increase in classes, the team's total workload dropped to 23.5. This is also because the team focused on smaller tasks like Paper etc.

 Sprint 8 in figure {{ref>fig:sprint8}} covered the period from April 30th to May 14th, 2026, with an initial workload of approximately 61 story points. The burndown chart showed a typical late-crunch pattern: after a small reduction at the start of the sprint, progress stayed mostly flat until May 12th, when most tasks were completed. By the end of the sprint, the remaining workload had decreased to around 23 story points, showing significant progress despite work being completed mainly at the end of the sprint. Sprint 8 in figure {{ref>fig:sprint8}} covered the period from April 30th to May 14th, 2026, with an initial workload of approximately 61 story points.

 By the end of the sprint, the workload had decreased to around 43 story points, indicating that only a small portion of tasks was completed during this sprint.

 +Back to the regular ~50 sprint points. The task that never gets finished is Project Management, as each week we need to add more to it. The teachers also asked us to add more to the app and paper, which is why there is such a big gap in the sprint backlog

 Sprint 12 in Figure {{ref>fig:sprint12}} covered the period from June 4th to June 11th, 2026, with an initial workload of approximately 31 story points.

 By the end of the sprint, the remaining workload had decreased to approximately 14 story points. Although the team did not fully reach the ideal burndown line, the sprint demonstrated a more consistent completion of tasks compared to earlier sprints, reflecting a gradual closing of the remaining project activities. By the end of the sprint, the remaining workload had decreased to approximately 14 story points.

 ==== Summary ==== ==== Summary ====
 +
 +
 +
 +This chapter described how the TRAQUA project was planned, organised, and managed from start to finish. Using an agile Scrum framework with weekly sprints, the team structured its work around a Jira backlog, milestone-driven prioritisation, and regular ceremonies — planning, stand-ups, retrospectives, and demos — that kept progress aligned with the deliverable deadlines defined in the project plan.

 +
 +
 +The twelve sprints reveal a clear evolution in the team's process. Early sprints showed a recurring "late-crunch" pattern, where most work was completed in a short window near the end of each cycle, and commitment regularly exceeded the work actually delivered. As shown in the velocity chart ({{ref>fig:velocity}}), the gap between committed and completed story points was widest in the middle sprints but narrowed considerably toward the end of the project: in the final sprints the completed work closely matched the commitment, indicating that the team's estimation and planning matured over time. The team settled at an average velocity of roughly 29 story points per sprint.
 +
 +The retrospectives were central to this improvement. Recurring issues — uneven workload distribution stemming from the team's mixed technical backgrounds, late absence notices, inconsistent Jira updates, and slow external feedback — were identified and acted upon, including a revised Definition of Done that restored burndown accuracy after Sprint 3. Risk management and procurement were handled proactively, with early ordering and backup suppliers limiting the impact of component delays.
 +
 +Overall, the project was delivered on schedule and met its milestones, and the team finished with a markedly more predictable and disciplined process than it began with. With the product developed and the project successfully managed, the next chapter turns to the marketing plan, examining how TRAQUA could be positioned and brought to market.
