Abstract

Over the last decade, the rapid development of the information and communications technology (ICT) has increased the use of information systems in the public sector. In a fast pace, the ICT technology has evolved and switched to more advanced setting to fulfill the system’s intricate demand. Apparently, some agencies in public sector are recognized to still be using an old and outdated information system supposedly for the reason it brings high business value. System with such circumstances is known as Legacy Information System (LIS). However, maintaining LIS involves such significant technical problems. Legacy systems are hard to maintain. There are only a few experts who understand the system, with no much proper documentation prepared, requiring high maintenance costs. This triggered the agencies to come with a decision in determining the appropriate action towards the LIS implementation. This paper therefore aims to address this concern by providing guidance in assessing the LIS and suggesting the befitting response in a form of a model based on the identified evaluation factors. This study adopted qualitative approach, which incorporates the theoretical and empirical phase. The theoretical phase is conducted by analysing existing literature of the information system assessment models and methods which are the ISO 25010, ISO 25012, Hierarchical Model and Renaissance Method. The empirical is conducted by employing interviews with informants that involved in the use of LIS. Data from the theoretical and empirical study were analysed using content analysis. The model then was validated by selected experts that are experienced in the business and technical of the public sector. The model combines three aspects; namely the business-value, technical quality and organisational aspects. This model contributes as references for the management people in assessing the LIS for the public sector.
