The increased adoption of technology in government-driven processes and services over the years has led to the use of information and communication technologies (ICTs) as mechanisms and platforms for citizens to access justice services and participate in the judicial process. In Uganda, there are current and ongoing efforts, through e-justice initiatives in the Justice, Law and Order Sector, to integrate case management information systems in criminal justice institutions as a means of improving worker productivity, facilitating information sharing, collaboration, better information access by the general public, citizen engagement and satisfaction with public services. The focus for this study was to devise a model that provides guidance on how to develop integrated information systems that are usable – by supporting improved human-driven legal processes, increased citizen engagement and facilitation of interaction between justice agencies and the general public. Based on the requirements for usable integrated information systems obtained from the review of literature and a survey, a model for guiding development of usable integrated case management information systems known as the Architecture-driven Usability Process Model (AdUPRO) was created.

E-government initiatives in developing countries still suffer from lack of interoperability, despite the existence of e-government interoperability frameworks in literature. For example, Uganda's e-government landscape is fragmented within and across agencies. To provide preliminary insights into addressing this, exploratory interviews were conducted to investigate why the e-government interoperability challenge prevails in Uganda, and findings were used with respect to existing literature to specify required strategic interventions. These strategic interventions point to the need for three intertwined capabilities, i.e., a regulatory and governance framework, a capacity building and sustainability framework, and an adaptation and customisation framework for e-government implementations. Therefore, the relevance of this paper is two-fold. First, to give insight into strategic interventions that developing economies (that share Uganda's context) can explore to address e-government interoperability. Second, to stimulate researchers in countries that have attained e-government interoperability to publish detailed technical guidelines on implementing the strategic interventions proposed herein.

Gartner advises that for enterprise architecture development to be successful, it is vital that enterprise architects ensure effective communication and also form virtual teams that create and agree on enterprise architecture content. One of the ways to achieve this is to enforce Collaborative Decision Making (CDM) during enterprise architecture creation. Guided by Design Science, we are developing a method referred to as Collaborative Evaluation of (Enterprise) Architecture Design Alternatives (CEADA) to enable CDM during enterprise architecture creation. The method attempts to resolve challenges in enterprise architecting that are caused by ineffective collaboration between enterprise architects and organizational stakeholders. Requirements for CEADA have been defined based on the causality analysis theory, the generic decision-making process, enterprise architecture frameworks (and literature), and the CDM theory. In addition, Collaboration Engineering has been used to design a collaboration process to address these requirements. Models describing the requirements and the design of the collaboration process, have been evaluated using the analytical, experimental, and observational methods. This paper discusses the implications of findings from these evaluations and presents the validated requirements for realizing CDM in enterprise architecture creation. Thus, this research generally attempts to strengthen enterprise architecting guidelines with collaborative activities, so as to enable effective execution of collaboration-dependent tasks.

Several challenges in enterprise architecture development indicate the need for collaborative decision making to be deployed during architecture creation However, how this should be achieved remains ad hoc This paper, therefore, presents an evolving theory that is currently being used to guide the development of a method for supporting collaborative decision making during enterprise architecture creation The first iteration to evaluate the relevance of the concepts in this theory was done using an exploratory survey, and the findings are briefly presented.

Effective execution of collaborative tasks during enterprise architecture creation helps to increase stakeholders' involvement and awareness in the architecture effort. However, enterprise architecture approaches lack detailed support for collaborative tasks. In an effort to address this, an exploratory survey was conducted among enterprise architects to investigate issues associated with executing collaborative tasks during enterprise architecture creation. Accordingly, this paper discusses mainly three aspects. First, it discusses how issues that were reported in the survey can be addressed by adopting the design science research methodology to guide the development of a process or method that supports the execution of collaborative tasks in architecture creation. The developed process is principally rooted in collaboration engineering and soft systems methodology (SSM). Second, the paper discusses how the developed method can be used to supplement enterprise architecture approaches that are used in practice (e.g. TOGAF) with support for executing collaborative tasks. Third, the paper discusses key findings from evaluating the developed process in two real organizations.
