Improved quality, risk reduction and better life, now is the time to change. Large enterprises are challenged continually to meet the demands of today's ever changing market needs while still increasing quality. The impact to business reputation through failures in IT has never been so high. Challenges such as the pandemic hit, highlighting the need to change the way we worked, where we worked and with no notice to prepare for it at all. Given all these challenges and changes, enterprises need to take a new look at how to achieve high quality with their software development practices. This book provides a detailed view into the complex software environments, including IBM Z, and provides a framework for how to drive the quality while increasing the speed of delivery to meet the business demands. Through stories and a little history of how these systems developed, this book explains how the new ways of working can be used across the enterprise, including the systems of record to drive that speed and quality.
