Design and Evaluation of a Digital Document Management System for Office Efficiency

Thesis Abstract

In contemporary office environments, the management and retrieval of digital documents remain critical challenges that impede organizational efficiency and productivity. Many offices continue to rely on traditional manual systems, resulting in delayed access, increased operational costs, misplacement of critical documents, and reduced workflow agility. Addressing these issues necessitates the development of effective digital solutions to streamline document handling processes. This study aims to design, implement, and evaluate a comprehensive digital document management system (DDMS) tailored for office contexts to enhance operational efficiency. The specific objectives include assessing existing document handling practices, designing a user-centered DDMS prototype, evaluating its usability, and measuring its impact on office productivity. Employing a mixed-methods research design, the study integrates qualitative and quantitative approaches to generate robust findings. The researcher adopted the pragmatism paradigm to facilitate a comprehensive understanding of user requirements and system performance. The population comprised office staff and administrators from twenty government offices within a metropolitan city, with a total population of approximately 500 employees. A stratified random sampling technique was used to select a sample size of 150 participants, ensuring proportional representation across departments. Data collection instruments included structured questionnaires for quantitative data, semi-structured interview guides for qualitative insights, and system usability questionnaires based on the System Usability Scale (SUS). The researcher also developed a prototype DDMS using user-centered design principles, incorporating features such as centralized document indexing, role-based access controls, and search functionalities. Data analysis involved descriptive statistics to summarize respondent demographics and current practices, inferential statistics such as paired-sample t-tests to assess pre- and post-implementation productivity variations, and multiple regression analysis to identify predictors of system acceptance. The qualitative data from interviews were thematically analyzed to extract user perceptions and challenges, complementing quantitative findings with contextual insights. The evaluation of the DDMS's usability relied on SUS scores, with a target threshold score of 68 indicating acceptable usability. Additionally, system performance metrics such as retrieval time and error rates were recorded to assess functional responsiveness. Expected findings reveal that the implementation of the DDMS significantly improves document accessibility, reduces retrieval time from an average of 4.5 minutes to under 1 minute, and increases overall office productivity by up to 30%. User feedback is anticipated to indicate high usability scores, with positive perceptions related to system ease-of-use, security, and integration with existing workflows. Challenges such as initial resistance to change and technical training needs are also expected to emerge, highlighting areas for future improvement. The study aims to establish a statistically significant relationship between system adoption and enhanced productivity, supporting the theoretical foundation provided by the Technology Acceptance Model (TAM) and the Information Systems Success Model. This research contributes to the existing body of knowledge by providing a validated framework for designing and evaluating digital document management systems specific to office environments, emphasizing user-centered approaches and measurable productivity gains. Its theoretical contribution extends TAM and IS success models by contextualizing their application within digital document management. Practically, the study offers actionable insights for policymakers and office managers seeking to digitize document workflows and optimize organizational efficiency. The main conclusion suggests that well-designed DDMSs, aligned with user needs and organizational contexts, can significantly improve document handling and overall office productivity. It recommends broader adoption of tailored DDMS solutions, comprehensive staff training programs, and iterative system improvements based on user feedback. Future research avenues include exploring integration with cloud-based platforms, mobile accessibility, and cross-organizational interoperability to further enhance the scalability and flexibility of digital document management systems.
