Structural way of thinking as applied to quality assurance management

Some major structures for improving the quality of software are described. It is noted that defects in software are the result of imperfections in the development process and that high quality is achieved through aiming for a better process. Structures are introduced in the product structure, the product architecture, and the work processes. As people constitute an essential part of the process, the human error problem and work time constancy are considered. Based on these, structures and general principles for improving quality are explained. Progress is attained by education in the broad sense. The present work is written for managers in software fields
