“…The world is currently transitioning to the fourth industrial revolution, which features advanced technologies. The fourth industrial revolution that is closely related to smart features, the globalisation of data usage, and information integration to achieve expected future advantages has begun to attract researchers' attention in recent literature [31][32][33]. Organisations can profit from the transition to the new revolution in a number of ways including by improving organisational competitiveness and increasing flexibility and productivity through the use of modern technology [34,35].…”

A Qualitative Study of Legacy Systems Modernisation for Citizen-Centric Digital Government

Legacy systems are valuable assets in most public sector agencies that have been in use for a long time. These systems support government service delivery to the citizens and maintain vital public administration functions and data. However, legacy systems are often related to technical difficulties that impede innovation efforts. The maintenance of the systems has become challenging and incompatible with the demands of digital transformation in the public sector. Due to their importance, the systems cannot be easily discarded. Rebuilding the old systems from scratch entails a long development timeline, high cost, and the loss of critical service functionalities. These circumstances encourage the public sector agencies to implement the modernisation of legacy systems. However, the modernisation effort for legacy systems in the public sector is not straightforward. Besides technical aspects, it should also consider non-technical aspects, including the requirements of the new era of citizen-centric digital government. In order to achieve this aspiration, a complete strategy must be developed to serve as a guide for government agencies. Hence, the purpose of this study is to develop a comprehensive guideline for the public sector. The research has been developed using a qualitative methodology that incorporates the theoretical and empirical phases. The theoretical phase was conducted through a literature review of previous studies related to the research topic. The empirical phase in the public sector was implemented and analysed using phenomenology and grounded theory methods. A total of 19 informants were involved in the individual and focus group interviews conducted. The study results revealed that human, process, product, and organisation aspects as well as the related characteristics of the citizen-centric influence the legacy systems modernisation in the era of digital government. The findings contribute as a complete guideline for the public sector agencies in modernising the legacy systems in line with the citizen-centric digital government vision.

“…In implementing legacy systems' modernisation, several aspects should be taken into account. In addition to the technical aspect, modernisation also involves business, organisational, and environment aspects [10,15]. In realising the government's directions, the delivery system also needs to incorporate a citizen-centric design that is more interactive, easy to use, and involves the participation of citizens [18,20].…”

“…The new system will also not necessarily be similar in terms of its ability compared to the legacy systems that have been operating stably for many years [6]. These factors led many organisations to choose modernisation to ensure that legacy systems remain relevant in delivering the best services [14,15]. The modernisation of legacy systems is important when the maintenance of the old systems has been inappropriate due to the technical constraints and unable to meet the increasingly challenging new demands [16].…”

Legacy Systems Modernisation for Citizen-Centric Digital Government: A Conceptual Model

Information technology and communication (ICT) plays an important role as a catalyst for organisational development and innovation. However, old information systems that are known as legacy systems often expose organisations to the risk of business failure. These systems are not only impeding the advancement in technology strategy but also hindering the organisations’ business competitiveness. Nevertheless, legacy systems are essential in supporting critical functions in organisations including the public sector and could not be scrapped easily. These systems need to be given a new strength through modernisation to continue providing the best service in line with global trends. Modernisation is a complex task that involves several related aspects. In the context of the public sector, legacy systems involve a complicated information relationship, environment, and culture, while ensuring the citizens are of high priority. The implementation of a digital government represents the transformation of the public service delivery to the citizens that emphasises a citizen-centric design. This study, therefore, aims to address this concern by reviewing the factors involved and suggesting a guideline in the form of a conceptual model to assist in the modernisation of legacy systems for a citizen-centric digital government. Data from the theoretical study were analysed using content analysis. The results show that the legacy systems’ modernisation comprised four main aspects, namely human, process, product, and organisation aspects, with related factors and elements. This model contributes as a reference for the public sector and provides overall guidance in performing legacy systems modernisation.
