Written from the perspective of a Technical Project Manager this study presents a scenario for a complete shift left software development effort.ampnbsp It brings considerations for Test and Support as early as the Inception Stage.ampnbsp Based on an innovative model Development Process Activity Cycles DPAC this representation allows visualization of progress including recursive activities.ampnbsp The model is based on an interpretation of the Deming quality cycle of Plan Do Check Act PDCA.ampnbsp ampnbspPeriodic Management reports are generated using configuration management data generated during the Act phase of each iteration.ampnbsp 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 ampnbspampnbspThis 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.ampnbsp 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 willampnbspampnbspampnbspampnbspampnbspampnbspampnbspampnbsp See how the various disciplines constituting the software development process come togetherampnbspampnbspampnbspampnbspampnbspampnbspampnbspampnbsp Understand where in the iterative development process progress ampnbspcan be measured and control exercisedampnbspampnbspampnbspampnbsp
