Introduction :
With the increased number of redevelopment projects across Hospital Authority, department users are now more often involved in site inspections before handover in which they have to identify defects to be rectified by contractors.
Currently, users will record the defects on paper during site inspection and input the defects with photos one by one into excel after going back to their office. The excel will be sent back and forth between different parties for consolidation and follow up. This method is extremely ineffective and time-consuming as each project can involve thousands of defects. Users often report data loss and outstanding rectification works throughout the period.
Digital Defect Management System (DDMS) provides shared electronic and online platform among various stakeholders in which users can record the defects with photo via mobile phones on site. The data will be instantly stored and automatically send to contractor for immediate action.
The adoption of the system can potentially bring us the below merits:
1) Instant Input: reduce administrative workload and hence users can focus on healthcare services;
2) Traceable record: enhance supervision over workmanship and reduce data loss;
3) Enhance communication: accessible for all parties
Objectives :
1) To familiarize users with the features and capabilities of the system
2) To collect feedback on the usability, performance, and user experience of the system
Methodology :
Trial sessions with 24 participants were held in Aug 2023 at KCH. One simulation center with 10-15 photos of simulated defects was established. A demonstration training session on the system was provided, followed by a 25-minute trial session by users. Evaluation by a self-report questionnaire was carried out, followed by a detailed analysis.
Result & Outcome :
Results
Majority of respondents were satisfied with the performance of DDMS, especially the ease of use and enhancement on efficiency. 95% of the respondents would recommend the system to colleagues and some suggestions were collected to further improve the user experience, such as developing bilingual forms and simplifying the user interface.
Conclusion
Kowloon West Cluster Planning & Commissioning (KWC P&C) Team proposes to adopt of DDMS in KWC Capital Projects as pilot, so as to enhance efficiency and improve staff satisfaction during site inspection and handover.
