Each step of the systems analysis and design life cycle requires the proper tools and direction. The image on the cover suggests that this process is much like plotting a course through the open sea. As the captain gathers information on the present bearing, so, too, does the analyst by assessing the needs of the client. For example, the map represents various ports of call during the journey, much like the stages of the SDLC. As the analyst moves from one stage to the next, the final port looms on the horizon. The drawing compass, spyglass, and navigational compass symbolize the tools the analyst will use throughout the evolution of the system. The architecture of the system will be determined by the course that is set. Tools such as CASE, existing software, and programming may be utilized. The additional navigational compass and drawing compass on the back cover represent a smaller set of tools, or subset, which the analyst may use to check the progress of the system in the prototyping or maintenance/review stages. With the proper use of the information and tools available, the analyst, like the captain, may embark upon a journey once a course has been charted through the waters of information systems.
