Essay / Research Paper Abstract
A 4 page paper presenting a plan for gathering information regarding a planned system change at estate appraisal company DEF Corporation. The system the company currently uses appears to be adequate for its own needs for the present, but alteration of processes has the potential of greatly improving customer response capabilities, which in turn positively affects DEF Corporation’s competitive advantage while also increasing DEF’s productivity. The paper discusses hierarchical decomposition of the current IT system, and interviewing stakeholders using a questionnaire to ensure uniformity and completeness of response. Bibliography lists 4 sources.

J. Edwards Deming (1986) voiced the standard of continuous improvement of process in his book, Out of the Crisis. The system that real estate appraisal company DEF
Corporation currently uses appears to be adequate for its own needs for the present, but alteration of processes has the potential of greatly improving customer response capabilities, which in turn
positively affects DEF Corporations competitive advantage while also increasing DEFs productivity. The purpose here is to discusse hierarchical decomposition of the current IT system, and interviewing stakeholders using a
questionnaire to ensure uniformity and completeness of response. How to Begin A wise approach is to begin the decision-making process with a hierarchical
decomposition of the current system, relative to identified needs for both the present and the future. Martin, Brown, DeHayes and Hoffer (2002) give a concise definition of hierarchical decomposition
that can make sense to even the most non-technical reader. The authors describe "the system" as "a set of interrelated components" (Martin, et al., 2002; p. 318), and that
any one of the components making up the larger system can itself be viewed as a system. In turn, this subsystem can further be broken down into a more
narrowly-defined set of components, which also may be able to be viewed as subsystems themselves. Martin, et al. (2002) explain that there are five primary goals of hierarchical decomposition:
* Break the larger system down into more manageable and understandable segments; * Analyze or change only part of - rather than all - a system; * Allow chronological design
or construction of a specific subsystem; * Allow targeted use of a specific subsystem; and * Allow more independent operation of system components.
