One of the most important activities in the systems engineering process is the
determination of the best implementation method from a set of alternatives.
This project describes a process that can be followed to evaluate a set of
implementation alternatives. This process consists of performing the
following activities: Definition of the need, requirements and functional
analysis, evaluation of the alternatives, requirements validation, and risk
identification. To clarify the activities in the evaluation process, the project
follows a case study in which the XYZ Corporation determines the best
implementation approach for providing access to a remote database over low
speed communications lines.
Three alternatives were evaluated by the XYZ Corporation. After performing
the evaluation, an HTML only implementation approach was selected. This implementation had the highest performance and dependability compared to
the other alternatives. Regional users will use a Netscape browser to view
HTML pages stored at the corporate headquarters. A web server located at
the corporate headquarters will interface with the database server by
performing the required additions, updates, and queries to the corporate
database. The web server will also format the returns into HTML pages for
viewing at the regional sites.
