OBJECT-ORIENTED SYSTEMS ANALYSIS: AN ARTICLE SUMMARY & CRITIQUE
The article "OO Systems Analysis: Is It or Isn't It?" is summarized and critiqued. The article is considered within the contexts of (1) summary, (2) major conclusions, (3) significance to systems analysts, (4) major weakness, and (5) critique.
This article identifies problems with the conceptual approach of most systems analysis methods. Once these problems have been identified, the authors of the article company selected major systems analysis methods both with one another and with a new systems analysis model that they propose in this article. The framework for the comparison of the systems analysis methods is the set of problems previously identified with the conceptual approach to systems analysis methods. The authors then describe and discuss a conceptual approach to systems analysis that they propose and then present and discuss a systems analysis model based on this conceptual approach which they have developed. Their model is named the Object-Oriented Systems Analysis Model. Following the presentation of the Object-Oriented Systems Analysis Model, the authors present what they refer to as metamodel of their Object-Oriented Systems Analysis Model. The article closes with a statement of conclusions drawn by the authors with respect to their findings presented in the article.
The first of the major conclusions drawn by the authors is that the Object-Oriented Systems Analysis Model that they presented in the article is not a "stand alone" analytical method, but, rather, is "the analysis component of a much larger effort that also includes object-oriented systems specification, design, implementation, evolution, and reverse-engineering." [1:31] The second major conclusion drawn by the authors is that the inclusion of their Object-Oriented Systems Analysis Model as a component of a broader framework of systems development facilitates the ability of syste...
