Assessing User Acceptance And System Development Priorities Of An Asset Disposal System: A TAM And QFD-Based Study At A State-Owned Electricity Company

Abstract

Abstract - As part of its ongoing digital transformation, PT PLN (Persero) is streamlining operational processes through the adoption of integrated information systems. One of these initiatives is the Asset Decommissioning Information and Monitoring System (SIMPUS), a web-based platform integrated with SAP to manage the disposal of Non-Operational Fixed Assets (ATTB). SIMPUS was developed to replace a manual process plagued by data errors, low transparency, with delays of up to five years. While SIMPUS 1.0 successfully reducing disposal cycle times from years to months, a pre-survey revealed user resistance due to a complex interface and technical limitations. This study integrates Technology Acceptance Model 2 (TAM2) and Quality Function Deployment (QFD) in two stages. First, a census survey of all active SIMPUS users (N=610) yielded 150 valid responses, analyzed with SEM-PLS to test TAM2 hypotheses. Second, SEM-PLS path coefficients were applied as weights in QFD to prioritize user needs based on their influence on behavioral intention. Results show perceived ease of use and organizational support as the main drivers of adoption, while subjective norm was excluded due to PLN’s hierarchical, procedure-driven culture. QFD identified three priorities for SIMPUS 2.0: role-based UI/UX improvements, new features (bulk upload, digital signatures), and streamlined verification workflows—forming a strategic roadmap for a more adaptive and user-focused system.
