7. Post-Event Evaluation — 3L Retrospective

Following the conclusion of UbuCon Asia 2025, a comprehensive internal retrospective was conducted using the ‘Liked, Learned, Lacked’ (3L) framework. This process aimed to evaluate the organizational success objectively, capture operational insights, and define concrete actionable items for future events.

7.1 Liked (Strengths and Successes)

The team identified several areas that were highly successful and contributed significantly to the positive attendee experience:

Effective Team Coordination: The institution of regular coordination and bi-weekly meetings between the global steering committee and the local organizing team was instrumental. This rigorous schedule ensured clarity in role distribution, minimized friction, and streamlined cross-border operational tasks.
Agile Operational Response: The prompt retrospective meeting held immediately after Day 1 allowed for rapid identification and adjustment of operational issues. These swift changes significantly improved the flow and efficiency of Day 2 activities.
Positive Attendee Experience: The event’s commitment to hospitality, particularly during the closing ceremony and the overall attendee management, was highly appreciated by both international guests and local participants.
Logistical Clarity: The effective deployment of signage and room labels significantly helped attendees navigate the venue, which was crucial given the large attendance.
Programmatic Innovation: The introduction of a dedicated workshop room which successfully hosted 6 hands-on workshops was a major strength. This feature directly addressed community demand, substantially increasing the opportunities for deep, practical learning.
Volunteer Engagement: High and proactive engagement from the on-site volunteer team was critical. Their dedication ensured smooth daily operations, logistical support, and a welcoming environment for all participants.

7.2 Learned (Improvements and Operational Lessons)

Key organizational lessons were documented to refine processes for future events:

Venue Layout Optimization: The distribution of session tracks across multiple, non-adjacent floors created unnecessary navigation challenges for attendees. Future events should prioritize venues that allow session tracks to be consolidated onto the same or adjacent floors to enhance attendee flow and manage traffic.
Registration and Check-in Efficiency: While Day 1 saw high attendance, the registration process resulted in bottlenecks and significant queueing. Future planning must allocate more dedicated check-in desks or implement staggered registration windows to handle peak influx more smoothly.
Internal Communication Tools: Reliance on on-site digital communication (Matrix) proved insufficient for rapid, mission-critical staff needs. Moving forward, the team should adopt dedicated real-time tools, such as professional walkie-talkies, for immediate and reliable staff-to-staff communication.
Logistical Timeliness: The finalization of the international day-trip logistics was deemed too late in the process. Clearer schedules and definitive plans for international guests must be communicated and finalized earlier in the planning timeline.
Sponsorship Strategy: The need to strengthen and diversify fundraising was noted. Starting sponsor outreach, particularly global efforts, earlier in the planning cycle is essential to secure more consistent funding streams.

7.3 Lacked (Challenges and External Roadblocks)

The retrospective identified specific challenges that created friction or delays during execution:

Check-in Bottlenecks: The combination of registration desk limitations and incomplete speaker pre-registration data caused significant delays on the morning of Day 1, impacting the start time of the opening session.
Wayfinding Gaps: Despite good signage, some larger halls and less-frequented rooms were still hard to locate, indicating a need for improved, larger-scale floor maps and better integration of directional volunteers.
Funding Dependency Risk: A high dependence on recurrent international sponsors was identified as a financial risk. Early, aggressive fundraising efforts combined with diversified global sponsor outreach must be prioritized to mitigate this dependency.
Customs and Import Processes: The customs and import procedures for specialized equipment (e.g., recording gear, international speaker kits) were occasionally slow. This necessitates clearer, pre-planned documentation and engagement with local partners to navigate import logistics more efficiently in advance of the event.

8. Recommendations for Future Editions (2026+)

Based on the Post-Event Evaluation (Section 7), the following recommendations are formalized to address organizational challenges, enhance logistical efficiency, and solidify the long-term sustainability and quality of UbuCon Asia.

8.1 Operational and Logistical Enhancements

The primary goal is to mitigate risks associated with venue complexity, registration bottlenecks, and on-site communication failures.

Area of Improvement	Recommendation	Rationale
On-site Team Sync	Hold a mandatory on-site global-local coordination meeting at the venue 24 hours before the event’s opening.	This finalizes role assignments, runs through contingencies, and ensures all team members are familiar with the venue layout before attendees arrive.
Internal Communication	Create clear, distinct volunteer/organizer identification (e.g., color-coded shirts or unique badges) and establish a walkie-talkie pool for real-time staff communication.	Reliance on digital communication proved unreliable. Dedicated physical communication tools are essential for immediate, mission-critical response.
Registration Flow	Utilize a dedicated event registration platform (or build a community-owned one) and implement staggered check-in windows.	Reduces queueing bottlenecks, provides better data control, and limits dependency on incomplete third-party data or last-minute approvals.
Venue Navigation	Consolidate session tracks to adjacent floors where feasible, and significantly improve both printed and digital venue maps.	Directly addresses the challenges attendees face in navigating complex, multi-floor venues (Section 7.2).
International Logistics	Finalize day-trip logistics (e.g., transport, itinerary, costs) earlier and provide a clear, detailed schedule to international guests upon arrival, if not sooner.	Ensures a smoother and more organized experience for international delegates.
Equipment Import	Prepare comprehensive customs/import checklists and nominate specific team members responsible for logistics and customs liaison well in advance.	Mitigates delays and risks associated with slow or complex customs processes for necessary technical equipment (Section 7.3).

8.2 Financial Sustainability and Sponsorship Strategy

To reduce dependency on recurrent international sponsors and ensure long-term financial stability, the following strategic changes are recommended:

Early and KPI-Driven Fundraising: Initiate the sponsorship drive significantly earlier (e.g., 9 months before the event) and set clear Key Performance Indicators (KPIs) for outreach volume and target conversion rates.
Diversify International Outreach: Actively target and onboard a diverse portfolio of international sponsors. This mitigates the financial risk associated with heavy reliance on local partners and ensures a robust global financial backing (Section 7.3).

8.3 Program Quality and Innovation

Future editions should continue the successful program innovations:

Dedicated Workshop Track: Maintain and potentially expand the dedicated workshop track, given the highly positive feedback and the high quality of the 6 workshops hosted in 2025 (Section 7.1).
Content Balance: Continue the successful balance between technical deep-dives (Talks), hands-on learning (Workshops), and community news (Lightning Talks), maintaining the nearly 43% CFP acceptance rate to ensure content rigor.
