Nowadays a huge number of enterprises make use of Information Systems (IS) in several areas. Since the software is one of the most important IS component it needs to be available and trustful. Lots of effort is invested to study critical factors that affects software development projects results. Survey research is the common technique to obtain the relationship between the variables considered inside the sample. Before the use the surveys must be validated, i.e., if it can measure the right things. This paper shows the steps to validate a survey to be answered by software development professionals. The methodological path is composed by the following steps: literature review, mapping of critical factor in software development, creation of a test survey, application of a initial test, refine and apply the survey, analysis the results throughout statistical methods, concluding the paper with the presentation and analysis of the critical factors found.

Effectivness of Health Information System Applications: Clinical Information and Diagnosis-Treatment Systems in Turkey

The distinctive quality of the new social structure is that information becomes the only factor of production. In today's organizations, public administrators are directly responsible for applying information to administrative processes. In addition to his managerial responsibilities, a knowledge based organization requires every employee to take responsibility for achieving efficiency. This has increased the importance of information systems in the decision-making process. Information systems consist of computer and communication technology, data base management and model management and include activity processing system, management information system, decision support systems, senior management information system, expert systems and office automation systems. Information systems in the health sector aim at the management and provision of preventive and curative health services. The use of information systems in healthcare has the benefits of increasing service quality, shortening treatment processes, maximizing efficiency of the time, labour and medical devices. The use of information systems for clinical decision making and reducing medical errors in the healthcare industry dates back to the 1960s. Clinical information systems involve processing, storing and re-accessing information that supports patient care in a hospital. Clinical information systems are systems that are directly or indirectly related to patient care. These systems include electronic health/patient records, clinical decision support systems, nurse information systems, patient tracking systems, tele-medicine, case mix and smart card applications. Diagnosis-treatment systems are information-based systems used in the diagnosis and treatment of diseases. It consists of laboratory information systems, picture archiving and communication system, pharmacy information system, radiology information system, nuclear medicine information system. This study aims to evaluate the effectiveness of health information system applications in Turkey. The first part of the study focuses on the concept of information systems and the types of information systems in organization structures. In the second part, clinical information systems and applications for diagnosis-treatment systems in Turkey are examined. Finally, the study evaluates applications in the health sector qualitatively from the new organizational structure, which is formed by information systems.

A Study of Value Addition by Information Systems to a Service Providing Business at the Meteorological Services Department in Zimbabwe

Many companies are using only a portion of what is needed in terms of Information Technologies (IT) and this has caused the researcher to study how best MSD can effectively utilize Management Information Systems (MIS). The objective that directed the study was to investigate value addition by information systems to a service providing business with specific reference to the weather station in Zimbabwe (Meteorological Services Department). Knowing the value added by MIS to one’s business and working environment is key to cope with the ever increasing challenges such as the volume of information resources, nature and quality of information, user needs and expectations, information and communication technology competencies and infrastructure, inflated cost of information resources and staffing needs. The researcher studied how information systems add value to the daily business of Meteorological Services Department (MSD) in the following areas of the organisation processes: products, quality, management, problem solving and decision of the organisation. The study on value addition by management information systems will assist in the improvement of the MSD in Zimbabwe. The study used a multistage sampling process for drawing sample from the target population. Secondary and primary data collection methods were used for data collection purposes. The source for primary data was questionnaire. Five different types of Management Information Systems that add value to the MSD were identified; Management Information Systems, Office Automation Systems, Executive Support Systems, Expert Systems, Decision Support System and Transaction Processing System. From the findings it was concluded that management information systems add value by allowing valid decisions which provide accurate and up-to-date information and performing analytic functions. This study demonstrated the importance of information systems in an organisation and outlined the fundamental roles of Information Systems (IS) which are to support business processes and operation, support decision making by employees and managers and support strategies for competitive advantage.

Modification of infant hypothyroidism and phenylketonuria screening program using electronic tools.

Background:Congenital hypothyroidism and phenylketonuria (PKU) are the most common cause for preventable mental retardation in infants worldwide. Timely diagnosis and treatment of these disorders can have lasting effects on the mental development of newborns. However, there are several problems at different stages of screening programs that along with imposing heavy costs can reduce the precision of the screening, increasing the chance of undiagnosed cases which in turn can have damaging consequences for the society. Therefore, given these problems and the importance of information systems in facilitating the management and improving the quality of health care the aim of this study was to improve the screening process of hypothyroidism and PKU in infants with the help of electronic resources.Methods:The current study is a qualitative, action research designed to improve the quality of screening, services, performance, implementation effectiveness, and management of hypothyroidism and PKU screening program in Isfahan province. To this end, web-based software was designed. Programming was carried out using Delphi.net software and used SQL Server 2008 for database management.Findings:Given the weaknesses, problems, and limitations of hypothyroidism and PKU screening program, and the importance of these diseases in a national scale, this study resulted in design of hypothyroidism and PKU screening software for infants in Isfahan province. The inputs and outputs of the software were designed in three levels including Health Care Centers in charge of the screening program, provincial reference lab, and health and treatment network of Isfahan province. Immediate registration of sample data at the time and location of sampling, providing the provincial reference Laboratory and Health Centers of different eparchies with the ability to instantly observe, monitor, and follow-up on the samples at any moment, online verification of samples by reference lab, creating a daily schedule for reference lab, and receiving of the results from analysis equipment; and entering the results into the database without the need for user input are among the features of this software.Conclusion:The implementation of hypothyroidism screening software led to an increase in the quality and efficiency of the screening program; minimized the risk of human error in the process and solved many of the previous limitations of the screening program which were the main goals for implementation of this software. The implementation of this software also resulted in improvement in precision and quality of services provided for these two diseases and better accuracy and precision for data inputs by providing the possibility of entering the sample data at the place and time of sampling which then resulted in the possibility of management based on precise data and also helped develop a comprehensive database and improved the satisfaction of service recipients.

Addressing Information Needs in Employment Services Provision in Italy: The Role of Codesign Networks

ABSTRACTThis article examines how coproduction can contribute to information quality in support of labor-market decision-making. Data was gathered on different types of Labor Market Intelligence (LMI) as decision-support systems for stakeholders, and subsequently by analyzing a specific program, with a focus on the role of information within its coproduction process. Results confirm the importance of information systems to support employment services design, but highlight the limitations of existing channels, and outline the types of information needed for policy effectiveness: those that are gathered through continuous relations with employers and jobseekers, and that often derive from participation in policy networks.

Procurement of a supply information system

Purpose – Given the high importance of information systems for procurement, surprisingly there have been little efforts to analyze the process and the relevant reasons for the procurement decision of such systems from a stakeholder perspective. The purpose of this paper is to explore these aspects in the context of low-value (C-)parts. Design/methodology/approach – Research is based on a case study in a pre-fabricator company in Germany and analyzes the process to procure a system for sourcing low-value parts. Findings – As a finding, the procurement process and decision attributes have been integrated into a framework which supports corporate decision-making considering the procurement reasons of all involved stakeholders (internal departments, external customers and suppliers). Research limitations/implications – Research is based on case study analysis. Findings are specific to case companies and the environment in which they operate. The framework should be tested further in different contexts. Practical implications – The developed decision frame supports the evaluation of different sourcing information systems, including clearly measurable criteria but also qualitative or company-strategic decision attributes. Originality/value – The combination of financial and other perspectives (operations, information technology (IT)-administration, system users, etc.), is used to evolve a robust ex-ante instrument for supporting buying decisions for procurement information systems. The case description also illustrates the findings and develops new insights about stakeholders and buying groups decision-making for information systems.

SISTEMAS DE INFORMAÇÃO – TEMAS DE PESQUISA ACADÊMICA NO BRASIL ENTRE 1994 E 2013

Retrieving the Brazilian academic research in Information Systems (IS) recent history is a welcome challenge, as it permits to evaluate its impact and to define the pathway to the future. This paper focuses on the topics identified in the set of 1,105 papers published between 1994 and 2013 in the proceedings of EnANPAD (Information Management – ADI – division) and EnADI. We analyze the papers as they fit the current areas of interest listed by the ADI division, separating the coverage period in two major subperiods: from 1994 to 2002 and from 2003 to 2013. The first subperiod is considered the IS leverage period while the second corresponds to the IS consolidation period in Brazil. The consolidation period parallels the time interval in which several Brazilian institutions formed and consolidated research groups of interest in IS. Not coincidentally, the paper’s coverage period corresponds to the existence of AMCIS, which has turned into an international gathering of scholars interested in the IS field. In its 2014 call for papers, AMCIS stimulated researchers from around the world to concern about the area's own history. We seek to gain consciousness about the road to take into the future of IS in Brazil, aiming to generate synergy among different actors in the field. The paper offers a list of important IS topics originated within the Brazilian research communities, observed in a longitudinal perspective. With significant contributions from a dozen institutions along the years (specially from UFRGS, USP and FGV), the proceedings of EnANPAD (ADI division) and EnADI form a representative set of scientific contributions from which one can grasp a set of key ideas established in the two studied periods.

Modeling and evaluation of information systems using coloured petri network

Article history: Received January 4, 2014 Accepted 1 June 2014 Available online June 9 2014 Nowadays with the growth of organizations and their affiliates, the importance of information systems has increased. Functional and non-functional requirements of information systems in an organization are supported. There are literally several techniques to support the functional requirements in terms of software methodologies, but support for the second set of requirements has received little attention. Software Performance Engineering (SPE) forum tries to address this issue by presenting software methodologies to support both types of requirements. In this paper, we present a formal model for the evaluation of system performance based on a pragmatic model. Because of supporting the concurrency concepts, petri net has a higher priority than queuing system. For mapping UML to colored Petri net diagram, we use an intermediate graph. The preliminary results indicate that the proposed model may save significant amount of computations. © 2014 Growing Science Ltd. All rights reserved.

The Determinants of Strategic Information System Planning (SISP) Success: A Proposed Framework for Small and Medium-Sized Enterprises (SMEs)

The growing importance of Information System (IS) to support business operation demands for adequate IS planning. Good IS planning enables organizations to closely align the IS and strategic business objectives. Such alignment ultimately ensures organizations to gain competitive advantages from IS-related investment. Despite extensive works to understand SISP practices in large organizations, works are still limited in the context of Small and Medium Enterprise (SMEs). This issue is worth further investigation in view of the increasing importance of IS to support many facets of the SMEs operation. More importantly, due to inherent resource constraints among SMEs to invest in IS, top management commitment as well as user participation in IS planning activities are getting more crucial. This study, therefore proposes a framework to assess the effect of top management commitment and user participation on SISP success. The findings are of relevance for firm’s top management in ensuring SISP success.

Aplicações do Conhecimento em Atividades Operacionais de Gestão de Redes: Aplicação de Um Framework de Pesquisa no Campo de Empreendedorismo Social

Considering the growth of awareness around key soc ial issues, such as sustainable development and poverty, social entrepreneurship has been the s ubject of discussion in the media business and academia. In this context, the emergence of a new m odel of social management, based on the formation of intersectoral partnerships, has drawn attention to the importance of knowledge management mechanisms and management of interorgani zational networks in the development of innovative solutions. Therefore, in order to broade n the understanding of the entrepreneurial process in the social field, we propose a case stud y of the practices of network management from the point of view of applications of knowledge in a n socially-driven inter-organizational network. It was concluded that theories of knowledge managem ent and network management were helpful in understanding the phenomenon, because the empiri cal data confirmed the performance of applications of knowledge by operating activities i n networks, according to the research framework. Note, however, the exception of the impo rtance of information systems, considered as protagonists in literature and as instruments of secondary importance by respondents. We conclude further that the activities of knowledge m anagement are intrinsic to the nature of management of interorganizational networks activity , especially when aimed at generating innovations

The Effect of CRM Outsourcing on Shareholder Value: A Contingency Perspective

One central business activity that companies increasingly outsource is the information systems (IS) function. Previous research has shown that outsourcing of back-office IS generally has a positive effect on shareholder value of the outsourcing firm. Much less is known about the performance implications of outsourcing of another important IS function, namely, front-office customer relationship management (CRM) systems, where the vendor uses its own personnel and software to perform several CRM tasks. Previous, largely anecdotal evidence shows that the performance implications of outsourcing CRM range from very negative to very positive. To address this unsatisfactory state of knowledge, we provide and empirically test a contingency perspective on the performance implications of outsourcing CRM processes. We do so using the event-study methodology. The results are largely consistent with our contingency model. CRM outsourcing is more beneficial to firms that are high on information technology capabilities and low on marketing capabilities, and less beneficial when it concerns presales CRM. Similarly, although vendor economic distance has a positive influence on the outsourcing firm's shareholder value, vendor cultural distance has a negative influence. These effects are in turn significantly moderated by the type of CRM process outsourced. This paper was accepted by Sandra Slaughter, information systems.

The Need for Qualitative Methods in Undergraduate IS Education

Introduction curriculum for Information (IS) programs is in a flux presently owing to the much reduced enrollment across the nation. Students are simply shying away from IS programs. Even the prediction that there will be a great demand for IS-related jobs in the near future (U.S. Bureau of Labor Statistics, 2010) failed to increase enrolment in IS program across the United States. IS departments re-examined their programs and in some instances re-packaged their entire program to make it more attractive to students. With the changes in the curriculum, IS departments might also want to re-examine non-IS courses in their curriculum. A course that should be given more consideration is the qualitative research methods course. IS students in and Analysis Design and Human Computer Interaction courses are ill-equipped to utilize qualitative methods to gather and analyze users' requirement. Gathering and analyzing users' requirements is a critical step in the whole system design life cycle. Failure to correctly gather and analyze the users requirements would result in costly delays or failure of the entire system or project. This exploratory paper examines the need for the inclusion of qualitative methods course in the undergraduate IS curriculum. Literature Review need for an IS curriculum is greater in the 1980s than when it was first outlined in the position paper by a committee of the ACM (Nunamaker, Couger, & Davis, 1982). Even though the curriculum recommendations have expanded over the years, the motivations for the 1982-revised curriculum built upon those that motivated earlier curriculum efforts. expansion takes into consideration changes in the importance of information systems, advances in technology, improvements in information systems analysis and development processes, and an increased need for information systems management skills. Nunamaker et al. (1982) stress that in order for the information systems community to face the current and future demands; the curriculum should address the basic goals of people needs, skill needs, and tool needs. Furthermore, the basic philosophy of the IS program is based on the premise that graduates of the program will be employed for major segments of their careers in positions involving organizational information systems. They will * Assist in defining and planning information systems * Elicit information requirements for applications and assist in designing the systems * Implement information systems applications * Manage information system development and operation. All aspects of the global computing field continue to face rapid and frequent changes. As a result, university-level Information curricula need frequent updating to remain effective. IS 2010 Curriculum Guidelines for Undergraduate Degree Programs in Information is the latest curriculum recommendation. IS 2010 Curriculum Guidelines has four broad key characteristics that shape the outcome significantly. First, the curriculum reaches beyond the schools of business and management. Second, the outcome expectations of the curriculum have been very carefully reevaluated and articulated first in the form of high-level IS capabilities and then in three knowledge and skills categories. Third, the curriculum is structured so that it separates the core of the curriculum from electives with the intent of supporting the concept of career tracks. Finally, the design of this curriculum includes enough flexibility to allow its adoption in a variety of educational system contexts. (Topi, et al., 2010. p. vii) IS 2010 Curriculum Guidelines states the following as one of its key principles that guided the report is that The model curriculum should be designed to help Information programs to produce competent and confident entry-level graduates well suited to workplace responsibilities or further studies of Information Systems (Topi, et al. …

An Advanced Technology Selection Model using Neuro Fuzzy Algorithm for Electronic Toll Collection System

Selecting an optimum advanced technology system for an organization is one of the most crucial issues in any industry. Any technology system which makes business process more efficient and business management more simplified is one of the important Information System (IS) to the organization. The comprehensive framework is a three-phase approach which introduces two main ideas, one is the adopting of the McCall software quality model which is extracted from technology management essentials, and use the factors of McCall software quality model to be some of the technology selection criteria. Another major point is implementing and proposing a model based on this research using Neuro-Fuzzy algorithm to evaluate advance technology selection. This paper includes the concept of a new multi attribute selection process which combines both the Fuzzy logic (linguistic) and Neural network (integral valuation) methodology to evaluate or estimate a technology for Electronic Toll Collection System. Managers will be able to use this model for selecting a new technology in to their organization.

Proposal for the Creation of a Subdiscipline: Education Informatics

Background/ContextSoon after the United States Department of Education began making changes to the Education Resources Information Center (ERIC) system, education librarians concluded that there was a need for a fresh approach to addressing education information needs. Considering the importance of information systems in education, they agreed that a new subdiscipline of education should be promoted called education informatics. This subdiscipline would incorporate new technologies and learning strategies to enhance the capture, organization, and utilization of education information. Some of the information challenges facing the discipline of education are: gaps in existing information resources; lack of a centralized body of education information experts to influence the development of new education resources; scarce resources for the development of concepts, models, theories, and techniques related to the use of information and communication technologies (ICT) for learning and teaching; minimal understanding of how people access and use education information and digital information resources, services, systems, environments, and media for learning; and lack of support for international and cross-cultural collaborations in education informatics.Purpose/Objective/Research Question/Focus of StudyThe creation of a subdiscipline within the field of education that examines issues that fall at the intersection of education information and information technology is critical. Once there is a broader recognition of the existence of this subdiscipline, it is likely that research funding will increase, specialized expertise will be expanded, and new programs and systems related to education information will be developed.Research DesignThe research design for this article is an analytic essay.Conclusions/RecommendationsThe process of becoming an established discipline of education informatics could be advanced through an invited symposium. Grounding it in schools of education would establish an academic identity. Such an interdisciplinary field needs attention from funding agencies and research leadership; acceptance by faculty and students; and systemic implementation in universities. The establishment of a “center” for education informatics would address problems that require many resources, incubate new programs, facilitate cross-disciplinary collaboration, and attract outside funding. There is a need for a journal of education informatics that has a broader scope than educational technology. A research agenda could include the development and evaluation of concepts, models, theories, and techniques related to the use of ICT for learning; ways in which people use digital information resources, services, systems, environments, and communications media for learning; whether information literacy educators give adequate attention to teaching all aspects of information literacy; and how international and cross-cultural collaborations in education informatics can be supported.

The paper illustrates these lessons by using data from an empirical case study in the region of Crete in Greece. The author concludes by discussing some future directions in managing crises in the healthcare service chain, including the importance of distributive, adaptive crisis management through new technologies like mashups.

The impact of an emergency hiring plan on the shortage and distribution of nurses in Kenya: the importance of information systems

To analyse the effect of Kenya's Emergency Hiring Plan for nurses on their inequitable distribution in rural and underserved areas. We used data from the Kenya Health Workforce Informatics System on the nursing workforce to determine the effect of the Emergency Hiring Plan on nurse shortages and maldistribution. The total number of nurses, the number of nurses per 100,000 population and the opening of previously closed or new heath facilities were recorded. Of the 18,181 nurses employed in Kenya's public sector in 2009, 1836 (10%) had been recruited since 2005 through the Emergency Hiring Plan. Nursing staff increased by 7% in hospitals, 13% in health centres and 15% in dispensaries. North Eastern province, which includes some of the most remote areas, benefited most: the number of nurses per 100,000 population increased by 37%. The next greatest increase was in Nyanza province, which has the highest prevalence of HIV infection in Kenya. Emergency Hiring Plan nurses enabled the number of functioning public health facilities to increase by 29%. By February 2010, 94% of the nurses hired under pre-recruitment absorption agreements had entered the civil service. The Emergency Hiring Plan for nurses significantly increased health services in Kenya's rural and underserved areas over the short term. Preliminary indicators of sustainability are promising, as most nurses hired are now civil servants. However, continued monitoring will be necessary over the long term to evaluate future nurse retention. The accurate workforce data provided by the Kenya Health Workforce Informatics System were essential for evaluating the effect of the Emergency Hiring Plan.

Evaluation Model for Information Systems Benefits in Construction Management Processes

The importance of information systems (IS) implementation in construction management has grown rapidly, and therefore, a more practical method for IS planning is required. Prioritizing the construction management processes in which IS will be implemented is one of the key processes in IS planning, and for the prioritization purpose, the benefits of IS implementation must be examined. This research suggests an evaluation model for IS benefits in construction management processes. The model is based on the evaluation of IS implementation benefits at the construction management task level, and it is postulated that the benefits are composed of the effect and possibility of IS implementation. The research suggests four basic measures as the fundamental evaluation criteria and represents an overall evaluation process in the model. A case study is performed to validate this model via a statistical analysis, and the result shows that the four measures can explain at least 58% of the variance of expected benefit from IS implementation. The contributions of this paper can be summarized in two aspects. First, researchers may further enrich the understanding of IS benefits realization mechanism with the factors. Second, industry practitioners may use the model in their IS planning task.
