Written from the perspective of a Technical Project Manager this study presents a scenario for
a complete shift left software development effort. It brings considerations for Test and
Support as early as the Inception Stage. Based on an innovative model - Development Process
Activity Cycles (DPAC) - this representation allows visualization of progress including
recursive activities. The model is based on an interpretation of the Deming quality cycle of
Plan Do Check Act (PDCA). Periodic Management reports are generated using configuration
management data generated during the Act phase of each iteration. There is no Test stage in the
DPAC model Test is represented in the back swing Check Phase of each iteration.This approach
allows the user or Subject Mater Expert (SME) to contemplate the face of the system through
several iterations of design and development using the triad principle (Power of Three)
matching a programmer tester and member of the user community This approach incrementally
reveals the best fit to the intent of the vision statement and iteratively uncovers the needs
of the user while maintaining conceptual integrity. This book provides a holistic and
comprehensible view of the entire development process including ongoing evolution and support
staffing and establishment of a comprehensive quality engineering program. It describes
activity inside the belly of the beast. By including support services as a part of the
development model a complete return on investment (ROI) can be calculated and a value stream
can be measured over the entire Application Life Cycle. You will· See how the various
disciplines constituting the software development process come together · Understand where in
the iterative development process progress can be measured and control exercised · Review how a
quality engineering program will positively affect the quality of the development process ·
Examine how the quality of the development process profoundly affects the quality of the
software system Who this book is for Intended for a technical audience this work should be of
interest to all technical personnel including analysts programmers test and production
especially mid level managers and anyone familiar with the principles of a Lean Agile approach
to development.
