In spite of the best efforts of researchers and practitioners, Information Systems (IS) developers are having problems "getting it right". IS developments are challenged by the emergence of unanticipated IS characteristics undermining managers ability to predict and manage IS change. Because IS are complex, development formulas, best…

This research has two main goals: to develop an instrument for assessing Electronic Portfolio (ePortfolio) success and to build a corresponding ePortfolio success model using DeLone and McLean's information systems success model as the theoretical framework. For this purpose, we developed an ePortfolio success measurement instrument and structural…

Introduction: This paper presents an initial proposal for a formal framework that, by studying the metric variables involved in information retrieval, can establish the sequence of events involved and how to perform it. Method: A systematic approach from the equations of Shannon and Weaver to establish the decidability of information retrieval…

This paper presents a learning unit that addresses quality design in relational data models. The focus on modeling allows the learning to span analysis, design, and implementation enriching pedagogy across the systems development life cycle. Thriving Systems Theory presents fifteen choice properties that convey design quality in models integrating…

In a constantly changing global business environment, firms have no other choice but to continually expand their capabilities and sharpen their competitive edge. Toward this goal, an increasing number of organizations are turning to Enterprise Resource Planning (ERP) systems. An ERP system utilizes various kinds of information processing…

An opinion paper.

Informatics is a branch of computer science that concerns itself, in actuality, with the use of information systems. The objective of this paper is to focus on the business curriculum for graduate students and their gaining proficiency in informatics so that they can understand the concept of information, the access of information, the use of…

This document first outlines considerations relative to a systems approach to evaluation, and then argues for such an approach to the evaluation of information retrieval systems (ISR). The criterion of such evaluations should be the utility of the information retrieved to the user, and the ISR ought to be regarded as one of three interrelated…

This study demonstrates the systems approach to scientific and technical information behavior research through the application of a multidimensional model to data concerning the effects of higher level variables on professional job types. The model was first developed in a study examining organizational barriers to the flow of STI in…

SYSTEMS ANALYSIS CAN BE APPLIED TO THE PLANNING AND DELIVERY OF MENTAL HEALTH SERVICES. THE MODELS PRESENTED SHOW HOW A SYSTEMS APPROACH CAN BE USED TO ANSWER SOME OF THE KEY QUESTIONS IN PLANNING, ORGANIZING, AND EVALUATING MENTAL HEALTH SERVICE PROGRAMS. MODEL 1 APPROACHES THE TASK OF DEFINING AND CATEGORIZING MENTAL HEALTH AND RELATED PROBLEMS.…

Findings and recommendations from a study conducted to define the college's information needs, and to diagnose and assess the administrative data processing operations. (Author/MLF)

An information storage and retrieval system has been developed for reporting job placement and followup data of persons trained in industrial education programs in California public schools. The system is built around five forms: (1) school registration, (2) verification of enrollment, (3) verification of address, (4) in-class follow-through, and…

Presents a formal approach to information systems development and outlines the components of a structured systems development methodology. The various stages of the methodology are then reviewed in light of experiences gained in three consultancy projects in developing countries. (Author/CLB)

This document attempts to provide managers and designers of information systems with a usable, practical "building block" system for unit costing. The model is sufficiently flexible to be applicable to a wide variety of cost control requirements; costing elements include project, product, account, organization and function. Design of the cost…

Discusses system modeling and specification as it relates to object-based information systems development and software development. An automated system model based on the objects in the initial requirements document is described, the requirements document translator is explained, and a sample application of the technique is provided. (12…
