Organisations need to measure enterprise content management (ECM) workflow systems performance to achieve their mission and objectives. This requires an exploration of the business environment where ECM workflow systems operate using an appropriate decision-making method and business process management (BPM) values. This paper describes the Delphi method as an appropriate methodology and identifies CERT values as appropriate BPM values with the support from experts and experienced professionals to measure ECM workflow systems performance. CERT values are Customer orientation (C), Excellence (E), Responsibility (R) and Teamwork (T). The purpose of this paper is to explain how the Delphi method can be used to measure ECM workflow systems performance. Further, CERT values are described to drive the business processes through the Delphi method to measure workflow system performance. The paper examines the academic literature on Delphi studies, ECM and CERT values and the benefits of this combination of ideas are revealed. The Delphi method strengths are identified to measure ECM workflow systems performance. Overall, this study focuses on the Delphi rounds as decisionmaking criteria to formulate a methodology in combination with CERT values to evaluate ECM workflow systems performance.

“…Trying to address limitations of current notations to represent agent-based systems [23], hypermedia [24], security [25], workflow [26]. While adding variants to existing notations is useful, some people argue that by doing that, you might kill the original purpose of the notations and overload the cognitive load to understand it [27]. Even worse you are on the risk that the variant proposal to a notation might not be adopted by a community thus it might demand a lot of effort to keep updated, if we develop a software or create a plug-in of an existing software, of new graphical notation.…”

“…Even worse you are on the risk that the variant proposal to a notation might not be adopted by a community thus it might demand a lot of effort to keep updated, if we develop a software or create a plug-in of an existing software, of new graphical notation. Using the right notation for the right model [27], also represents a challenge when the notation does not exist at all, for instance, how to design an auditory user interface? Or when the notation lacks of expressiveness, for instance, in UML labeling method and class names with Italics to denote abstract Classes is not easy identified, sometimes, not even supported in existing solutions.…”

Computer Diagrams are the communication mechanism among the different stakeholders of the software development lifecycle. While they are though at school, and promoted to be used by students for current and future projects, we still do not see full adoption in real life context. The literature reviewed points out some reasons related to this issue and propose some solutions, but still the problem persist. In this paper, we present our findings of three years of research at the University while working with senior students on real-life projects. Different methodologies were used as an iterative process, improving the quality of the results year by year. We present the lesson learned including guidelines on how to facilitate novice engineers to adopt diagrams and produce them with high quality standards. The proposal is validated with a real life case study.

“…The evolutionary prototyping model involves: (a) the system requirement collection and analysis, (b) rapid designing, (c) developing the working prototypes, (d) initial customer evaluation, (e) improving the prototypes, (f) implementing the final products, and (g) maintaining the products (Carter et al, 2001;Guerrero-García, 2014;Bai, 2014). The evolutionary prototyping approach improves the flexibility of the system prototypes, helps to save time and effort during software development, allows developers to concentrate on the main functionalities of the system that they understand, and increase user requirement satisfaction since customers are involved throughout the development process (Chen & Huang, 2002;Xiaoshuan et al, 2009;Guerrero-García, 2014;Adarsh et al, 2017). The researchers adopted it because some of the system requirements were unclear and required customer feedback, and it reduces severe and critical flaws during the system testing (Carter et al, 2001).…”

Development of a secure multi-factor authentication algorithm for mobile money applications

With the evolution of industry 4.0, financial technologies have become paramount and mobile money as one of the financial technologies has immensely contributed to improving financial inclusion among the unbanked population. Several mobile money schemes were developed but, they suffered severe authentication security challenges since they implemented two-factor authentication. This study focused on developing a secure multi-factor authentication (MFA) algorithm for mobile money applications. It uses personal identification numbers, one-time passwords, biometric fingerprints, and quick response codes to authenticate and authorize mobile money subscribers. Secure hash algorithm-256, Rivest-Shamir-Adleman encryption, and Fernet encryption were used to secure the authentication factors, confidential financial information and data before transmission to the remote databases. A literature review, survey, evolutionary prototyping model, and heuristic evaluation and usability testing methods were used to identify authentication issues, develop prototypes of native genuine mobile money (G-MoMo) applications, and identify usability issues with the interface designs and ascertain their usability, respectively. The results of the review grouped the threat models into attacks against privacy, authentication, confidentiality, integrity, and availability. The survey identified authentication attacks, identity theft, phishing attacks, and PIN sharing as the key mobile money systems’ security issues. The researcher designed a secure MFA algorithm for mobile money applications and developed three native G-MoMo applications to implement the designed algorithm to prove the feasibility of the algorithm and that it provided robust security. The algorithm was resilient to non-repudiation, ensured strong authentication security, data confidentiality, integrity, privacy, and user anonymity, was highly effective against several attacks but had high communication overhead and computational costs. Nevertheless, the heuristic evaluation results showed that the G-MoMo applications’ interface designs lacked forward navigation buttons, uniformity in the applications’ menu titles, search fields, actions needed for recovery, and help and documentation. Similarly, the usability testing revealed that they were easy to learn, effective, efficient, memorable, with few errors, subscriber satisfaction, easy to use, aesthetic, easy to integrate, and understandable. Implementing a secure mobile money authentication and authorisation by combining multiple factors which are securely stored helps mobile money subscribers and other stakeholders to have trust in the developed native G-MoMo applications.
