Systems Analyst activities and skills in the new millennium
Journal of Systems and Software, 2004Co-Authors: Mark M Misic, David GrafAbstract:The nature of Systems development has continued to undergo change as new technologies emerge and impact the environment in which Systems must function. A nationwide survey of Systems Analysts was conducted to assess what tasks are most important, what skills are most important in completing the tasks, and how the tasks and skills needed may have changed over the last decade. The most important tasks were those associated with traditional Systems development, namely defining system scope, objectives, system requirements, as well as assessing the impact of Systems and evaluating their performance. Analytical skills were considered the most important skills overall, followed by technical and communication skills. The least important skills overall were interpersonal skills. When compared to results from a similar survey conducted in the early 1990s, the data from the present study revealed that while the most important tasks remained relatively unchanged, a number of shifts occurred in other aspects of the Systems Analyst's work that reflect changes in the technological environment.

the changing roles of the Systems Analyst
Information Resources Management Journal, 1994Co-Authors: David Graf, Mark M MisicAbstract:The role of the Systems Analyst continues to be integral to the backbone of the organization-the organization's information system. The nature of the Systems Analysts' activities and work environment has undergone many changes in recent years. A more computer literate user community, new Systems innovations, and a move toward cooperative Systems development have contributed to these changes. This study attempted to develop and clarify the roles of the Systems Analyst based upon the frequency of selected Systems Analyst activities within the context of human relationships encountered by the Systems Analyst.

ideal advertised and actual Systems Analyst skills the singapore context
Information Technology & People, 1996Co-Authors: Gordon M Hunter, Shailendra Jain C PalviaAbstract:The current software crisis has created a situation where organizations are faced with identified as well as hidden information Systems (IS) development backlogs. IS projects are generally behind schedule and/or over budget. Even after implementation, the IS does not necessarily solve all the original problems and is very difficult and costly to use and maintain. Software development and maintenance costs represent the major component of total information technology (IT) budget. Reports on research conducted in Singapore which addresses the question concerning the identification of the skills of Systems Analysts. Analyses this question from three different viewpoints (interviews about “excellent” Systems Analyst, newspaper advertisements for Systems Analyst positions, and a questionnaire regarding hiring, promotion, evaluation and training criteria for Systems Analysts). The research suggests that there is a discrepancy between the criteria established for the initial screening of candidates and the actual process followed for selection, evaluation, training and promotion of Systems Analysts. This discrepancy will result in the less than optimal use of Systems Analyst personnel and may be a contributing factor to the current IS software crisis. While the research was conducted solely in Singapore, it is contended that the results are generally applicable because of the emergence of what is referred to as an “occupational community” of Systems Analysts.

is student performance on the information Systems Analyst certification exam affected by form of delivery of information Systems coursework
Information Systems Education Journal, 2012Co-Authors: Wayne Haga, Abel Moreno, Mark SegallAbstract:In this paper, we compare the performance of Computer Information Systems (CIS) majors on the Information Systems Analyst (ISA) Certification Exam. The impact that the form of delivery of information Systems coursework may have on the exam score is studied. Using a sample that spans three years, we test for significant differences between scores obtained on three of the areas of the ISA exam by CIS majors who completed the coursework via classroom delivery with those who completed the coursework via online delivery. Results from the study are analyzed and conclusions discussed. Opportunities for further study are proposed.

changes in the Systems Analyst skill set 2006 versus 2001
2007Co-Authors: Wayne Haga, Charles H Mawhinney, Gerard J Morris, Jesse Stabile MorrellAbstract:This paper addresses the issue of what skills are necessary to be successful as an Information System Analyst. An empirical study was performed to investigate the skill set requirements for the Systems analysis position in the current job market and compare those requirements with those reported in a previously published paper. It is important to address these issues to be better able to advise students in an information Systems program and to better package the curriculum content. This study found evidence of changing roles and responsibilities and requisite skills compared to those previously reported.

semantics to energize the full services spectrum ontological approach to better exploit services at technical and business levels
Communications of The ACM, 2007Co-Authors: Amit P ShethAbstract:Amit Sheth, Kunal Verma, Karthik Gomadam LSDIS Lab, Dept of Computer Science, University of Georgia {amit, verma, karthik}@cs.uga.edu Introduction Services are pervasive in today's economic landscape, and services-based architectures are being rapidly adopted as IT infrastructure. The need to take a broader perspective of services to include people and organizational descriptions as opposed to technical interface descriptions has already been recognized as part of an overall vision of Services Science [3][5]. The focus of this article is to present the Semantic Services Science (3S) model, which seeks to demonstrate the essential benefits of semantics to the boarder vision of Services Science, with service descriptions that capture technical, human, organizational and business value aspects. We assert that ontology based semantic modeling and descriptions can be used to energize services across the broad service spectrum. In this article, we demonstrate how 3S approach could be used along three points in this spectrum: 1) semantic descriptions of standard Web services with the help of WSDL-S, semantic policies and agreements, 2) semantic descriptions of light weight Web services using Web 2.0 technologies (e.g. REST, AJAX) and 3) ontology based profiling of people and organizational aspects of the assets associated with the knowledge services. Why use semantics as the basis of the service model? Interoperability has been a key challenge in IT for well over a decade. While Electronic Data Exchange standards and XML has provided the basis for data exchange and syntax level interoperability, IT infrastructure needs semantic interoperability to fully exploit and interoperate with respect to all its data and service resources. The fast emerging Semantic Web shows how the use of formal knowledge representation, typically in the form of ontologies, leads to machine processable descriptions, and how the adoption of ontologies that provide common vocabulary and shared knowledge leads to improved semantic interoperability. There are three primary advantages of creating models that employ semantics -1) they promote reuse and interoperability among independently created and managed services, 2) ontology supported representations based on formal and explicit representation lead to more automation, and 3) explicit modeling of the entities and their relationships between them allows performing deep and insightful analysis. For example, if a particular business component is declared as critical, and the relationships between the business and IT components supporting them are explicitly modeled, simple semantic queries may allow business managers to verify if adequate IT resources have been allocated to that component [6]. This reasoning would have otherwise required a Systems Analyst with great deal of knowledge of both the business values and IT of the organization. 3S utilizes semantic descriptions to capture relationships between services, the people, the organizational aspects, the business values and allows business managers to reason on them to easily create new services and to efficiently allocate resources to the services. On the technical front, much of the modeling effort on services has so far focused on standard Web services in the context of SOA enabled by Web service Description Language (WSDL), SOAP (Simple Object Access Protocol, an XML-based message exchange format) and UDDI (Universal Description, Discovery, and Integration, a technical specification for implementing registries that allow publication and discovery of Web service). It is however possible to take XML-based descriptions used by these standard Web services (and in principle other syntactic descriptions of services) and annotate them with semantics specified in ontologies or conceptual models to gain the above discussed benefits of a semantic approach. The emerging field of Semantic Web Services (SWS), semantics is exploited to discover services using semantic (rather than syntactic) description, to more effectively integrate, compose or orchestrate services to support workflows or processes. The same approach to semantic interoperability can be accorded to fast growing web-based services using Web 2.0 technologies (e.g. REST, AJAX),
