Estimation of IT-project efforts for information system creation in the conditions of re-use of its functions

The object of this study is the process of estimation and control of an IT project. During the study, the problem of increasing the accuracy of estimating the efforts of an IT project to build an information system (IS) was solved. Research in this area is aimed at simplifying the original assessment methods or at applying elements of artificial intelligence to these methods. The task of the impact of the features of IS development methodology on effort assessment remains unexplored. During the study, the method of functional point analysis was modified. The proposed modification makes it possible to increase the accuracy of estimating efforts to build an IS under the conditions of re-using its individual functions. These conditions allow the construction of new system functions by reusing a previously developed function of the same system. The developed method was tested during the evaluation of efforts of an IT project to form the functional task "Forming and executing an individual plan for a research and teaching staff member of the department." The option of re-using one of the functions of a task during the construction of two other functions of the same task is considered. For this option, the estimate was 72 function points (the estimate using the standard method was 144 function points). The use of the results allows us to increase the accuracy in assessing the efforts of IT projects to construct IS under the conditions of applying the methodology of reuse of previously developed system elements. This, in turn, makes it possible to improve the accuracy of estimating time costs, personnel requirements, and financial costs for the implementation of IT projects for constructing IS. The results obtained are used to solve the task of estimating efforts during the planning of IT projects for developing information systems and their software

Perancangan Web E-Commerce Dengan Menggunakan Pendekatan WISDM

Cahaya Konveksi Shop is an industry that manufactures apparel, such as t-shirts, polo shirts, shirts, training pants, jackets, and so on. On a normal day the Cahaya Konveksit Shop can produce 100-500 t-shirts in a day, while at the beginning of the semester or new student registration at school, Cahaya Konveksi Shop can produce 500-1000 t-shirts in a day because many schools make uniform t-shirts for students new. The problem found from this store is that there are many competitors who have just started the same business as the Cahaya Konveksi Shop, which has an impact on reducing the number of orders. With this situation, stores are required to make innovations in service to consumers. The application of web-based E-Commerce is one solution to this problem. In the system there is also the WISDM Method (Web Information System Development Methodology) which is a method in system development that aims to make a program quickly and gradually so that it can be immediately evaluated by the user. In addition, WISDM also makes the process of developing information systems faster and easier, especially when user needs are difficult to identify. With this website, Cahaya Konveksi Shop has superior value that its competitors do not yet have, by adding features that can make it easier for sellers and buyers to do business. The result of this research is to create a web-based e-commerce information system at the Cahaya Konveksi Store

COVID-19 and the Digital Ecosystem: Using a Mobile App to Connect a Rural Community

The outbreak of the novel coronavirus disease in 2019 disrupted every aspect of human life, threatening the world’s public health system. Most countries accelerated their transition to digital technologies that support healthcare, social activities, learning, and shopping to minimise these disruptions. As COVID-19 propels nations towards the digital economy, epitomising the data age, the digital divide will be more pronounced even within the same country. The transition to the digital space has exposed Africa’s infrastructural deficiencies. Zimbabwe’s rural communities have limited access to information related to COVID-19 due to the unavailability of radio and television reception. In light of limited access to radio, television, and newspaper by rural communities, the study sought to develop a mobile app that can enhance access to information related to COVID-19. The Information System Development Methodology and agile software design principles guided the development of the app. The evaluation results show positive feedback regarding the usefulness and utility of the app. The findings indicate that the participants found the app very easy to remember, easy to learn, and perceived that it satisfied their information access needs. The results can be useful in improving the deployment of digital health solutions targeting rural and remote communities.

COVID-19 affected remote workers: a temporal analysis of information system development during the pandemic

ABSTRACT This paper explores the temporal complexity of remote working within information systems development (ISD). Traditional remote working literature is ill-equipped to deal with the COVID-19 context. An interpretive research approach is used to generate a qualitative data set, based upon the results of field interviews with key ISD professionals. The thematic analysis of the research data is classified based on a temporal complexity framework. The study provides several key takeaways that emerge when temporal complexity theory is applied to study COVID-19 affected remote ISD workers. It explores how temporal characteristics influence remote ISD working, while investigating the resulting challenges. Recommendations are provided which researchers and practitioners may focus on when researching and applying ISD methodology. This is the first paper which examines temporal complexity within remote ISD workers. This research will provide a starting point for ISD researchers and practitioners to test their commonly held temporal assumptions about remote working.

Logic Pluralism in Mobile Platform Ecosystems: A Study of Indie App Developers on the iOS App Store

The software development field has inherently been identified with two field-level institutional logics, i.e., logic of the profession and logic of the markets. Traditionally, information systems development methodologies have been used to reconcile the competing demands from these two logics. In this paper, we study how these two logics manifest in a platform-based software ecosystem where significant entrepreneurial opportunities are created for independent third-party app developers (indies). Specifically, we study how indie developers manage the two logics on the iOS platform ecosystem under the influence of the platform owner Apple. We first identify practices of indie developers consistent with the two field logics across three entrepreneurial domains, i.e., app ideation, execution, and marketing. Second, we identify areas where the two field logics may be in conflict as well as in coexistence. We show that indie developers enact logic conflict through disagreement and denunciation of the opposing logic. When logics that are inherently opposed appear to coexist, we investigate how app developers manage these opposing demands through a process we call logic synthesis. Using a grounded theory approach, we propose a model of field-level market and professional logics operating in the mobile app platform ecosystem and the practices reflecting such logics in the indie developer community. Our work contributes to the growing literature on platform ecosystems and the processes adopted by third-party app developers in such ecosystems, in addition to furthering the study of institutional logics in technology contexts.

A Preliminary Study on Gender Differences in Studying Systems Analysis and Design

Systems analysis and design is a crucial task in system development and is included in a typical information systems programme as a core course. This paper presented a preliminary study on gender differences in studying a systems analysis and design course of an undergraduate programme. Results indicated that male students outperformed female students in general in this course. However, regarding the different study focuses of the course, female students performed better in information systems development methodologies and systems analysis, whereas male students worked better in systems design. Discussions have been raised to explain the findings and it was suggested longitudinal studies could be conducted for a more generalized conclusion.

The Role of Platforms in Reconciling Logic Pluralism? A Study of Indie App Developers on the iOS Platform

The software development field has inherently been identified with two field-level institutional logics: logic of the profession and logic of the markets. Traditionally, information systems development methodologies (ISD) have been utilized to reconcile the competing demands from these two logics. In this paper, we study how these two logics manifest in a platform-centric software development context where significant entrepreneurial opportunities are created for independent third-party app developers (indies). Specifically, we study how indie developers manage the two logics on the iOS platform, under the influence of the platform owner Apple. We first identify practices of indie developers consistent with the two field logics across three entrepreneurial domains: app ideation, execution and marketing. Second, we identify areas where the two field logics may be in conflict as well as in coexistence. We show that indie developers enact logic conflict through disagreement and denunciation of the opposing logic. When logics that are inherently opposed appear to coexist, we investigate how app developers manage these opposing demands through a process that we term logic synthesis. We integrate the platform’s impact on indie developers’ logic enactment and logic synthesis. Using a grounded theory approach, we provide a model of field-level market and professional logics operating in mobile app platforms and the practices reflecting such logics within the indie developer community. Our work contributes to the growing literature on platform governance and platform ecosystems, in addition to furthering the study of institutional logics in technology contexts.

EXPLORING THE INFLUENCES OF THE USE OF ELEMENTS COMPRISING INFORMATION SYSTEM DEVELOPMENT METHODOLOGIES ON STRATEGIC BUSINESS GOALS

As the competitive pressure of the global market for information systems (IS) continues to increase, IS development enterprises should start to consider if and how the use of IS development methodologies (ISDM) influences their main strategic business goals. More precisely, they should start to consider two different dimensions of the actual use of ISDM: the number of times an opportunity for ISDM use arises and the number of times the ISDM is actually used. Otherwise, they run the risk of mismanaging their ISDM-related investments. The goal of this study is to develop a model that would enable academics and IS practitioners to better examine and understand how different dimensions of the use of ISDM influence strategic business goals of cost leadership, differentiation and cornering niche markets in IS development enterprises. Given the limited literature on the research topic, this study was considered exploratory and theory building in nature. The main result of the presented exploratory study is a clearly defined model for examining how different dimensions of ISDM influence strategic business goals. Exploratory results show that the actual use of ISDM has a significantly positive influence on strategic business goals of differentiation and cornering of niche markets, but not the cost leadership.

Developing an ISDM Adoption Decision Model Using Delphi and AHP

Research on information systems development methodologies (ISDM) adoption has been widely undertaken to highlight the experience of developed countries. Studies concerned with the status of ISDM in developing economies including the factors that influence and motivate their use, current trends, difficulties, and barriers to adoption are lacking. This paper explores these issues in a developing economy, namely Oman, and proposes an ISDM adoption decision model using analytical hierarchy process analysis informed by a survey and Delphi consultation. The findings from the survey reveal a lack of knowledge of ISDM amongst Omani Information Systems developers and the reliance on ad-hoc software development methods. Conversely, analyzed data reveals a trend whereby a majority of Omani organizations are gradually moving towards increased ISDM adoption and deployment. This has motivated the development of an adoption decision model to assist software companies to select the right ISDM adapted to their organizational needs in Oman. This model has a generic dimension and can be adapted to other socio-organizational contexts.

The Role of Modelling in Agile Methodologies

Modelling as a technique continually keeps important place in information system development (ISD) methodologies and is adopted for implementing systems effectively. Contrasting to modelling, agile methodology is a new concept. It aims to overcome shortcomings of early ISD methodologies. It welcomes changes and adapt to them. Meanwhile it is people-oriented. Used in the new methodologies, besides traditional roles, modelling has more critical roles in ISD methodologies.The report illustrates main roles of modelling, including traditional and new ones. Meanwhile, it also addresses idea of ISD is social with the roles of modelling.

Rule-based Expert Systems for Selecting Information Systems Development Methodologies

Information Systems (IS) are increasingly becoming regarded as crucial to an organization's success. Information Systems Development Methodologies (ISDMs) are used by organizations to structure the information system development process. ISDMs are essential for structuring project participants' thinking and actions; therefore ISDMs play an important role to achieve successful projects. There are different ISDMs and no methodology can claim that it can be applied to any organization. The problem facing decision makers is how to select an appropriate development methodology that may increase the probability of system success. This paper takes this issue into account when study ISDMs and provides a Rule-based Expert System as a tool for selecting appropriate ISDMs. The proposed expert system consists of three main phases to automate the process of selecting ISDMs. Three approaches were used to test the proposed expert system. Face validation through six professors and six IS professionals, predictive validation through twenty four experts and blind validation through nine employees working in IT field. The results show that the proposed system was found to be run without any errors, offered a friendly user interface and its suggestions matching user expectations with 95.8%. It also can help project managers, systems' engineers, systems' developers, consultants, and planners in the process of selecting the suitable ISDM. Finally, the results show that the proposed Rule-based Expert System can facilities the selection process especially for new users and non- specialist in Information System field.

Understanding acceptance of information system development and management methodologies by actual users: A review and assessment of existing literature

Despite the advantages of using IS methodologies, they are often rejected by actual users. Consequently, researchers have repeatedly attempted to understand why individuals accept certain methodologies while rejecting others. In order to differentiate what has been done from what needs to be done in research, a systematic review of academic studies that examine the acceptance of IS methodologies by actual users was conducted. This review revealed 19 articles. We found that the studies were either: (a) descriptive, (b) focused on specific determinants, or (c) applied a holistic approach, examining methodology acceptance from a number of dimensions. Furthermore, while cognitive aspects have received considerable attention, none of the publications studied the effect of habits, emotions and the personal characteristics of individuals. We also examined the studies with respect to the reported research practices, and thereby identified areas of improvement. Based upon our findings, we developed a research agenda to guide future studies on this crucial subject.

Information Systems Risk Paradigms: Towards a New Theory on Systems Risk

Abstract Systems risk is not dealt with sufficiently by current information system development methodologies. This paper seeks to identify new insights into systems risk using a case of IT failure in banking in the UK and Ireland. This paper uses Burnell and Morgan's (1979) paradigms of social and organisational theory: functionalism; interpretivism; radical humanism and radical structuralism as the lens through which the IT failure is examined. New theories around systems risk is an important ask for IFAC going forward and this paper provides a basis for a future study of the meta-theoretical assumptions underpinning systems risk.
