A true understanding of information systems requires more than memorizing hundreds of technical buzzwords. The second edition of Professor Steven Alter’s highly successful "Information Systems" goes beyond the buzzwords by using a practical, widely applicable approach for analyzing systems from a business professional’s viewpoint. The work-centered analysis (WCA) method is integrated throughout the book, providing a unifying vision for the material. The text also comes to life through examples within the chapters and true-to-life cases that open and close the chapters.
