James Wetherbe's text, Systems Analysis and Design, provides an excellen t introduction to systems analysis and design, to the information systems organization, and to the issues of constructing management decision support systems. After introductory material on the nature of systems , informations, and organizational processes which are fundamental concepts for an understanding of systems analysi s and design, Wetherbe focuses on the practical process o f systems development, including problem definition, analysis , design, and implementation. Within the systems analysi s section, he includes techniques such as Critical Success Factors and Business Systems Planning which link the manag-er's goals with information requirements. These framework s relate the concerns of the manager — how to control production , how to market new products, and how to monito r project costs to information systems requirements. I n essence, these approaches make sure that the right system s are being built.

In addition, the structured systems concepts have several methodologies and few examples have been available without high costs to an organization.
