A Reverse Chronology of Evolutionary Architecture and Agile Development

Our story opens with an architecture-centric systems development life cycle that allows for rapid, stable feature delivery. We then navigate backward from that desired state through an integrated evolutionary architecture and agile development approach to identify the attributes that enable it. In the course of our reverse narrative, we present methods for more rapidly realizing stakeholder business and mission goals by reducing the gap between solution architectures and their Agile implementations. We also discuss how evolutionary architecture and Agile implementation can quickly adapt to new and changing requirements under an iterative, incremental system capability delivery. We will use slides to tell our story (using real-world experiences) following this general outline and time allotment for a 45-minute presentation: 1. The End: SDLC Desired End State SE Process Quality Attribute Goals - Briefly summarizes SE performance, cost, schedule, and risk management goals Knowledge-based Acquisition and Delusive Transparency - How to better and more frequently inform customers between KA points Architecture and Implementation Quality Attribute Goals - Briefly summarizes desired quality attributes spanning design and development 2. The Middle: Managing Complexity and Risk 2.1 De-constructing Sprint N: To Serve Agile Development Teams Architecture-driven Use Case Specifications - Explains how use cases can bridge the gap between architecture and development Tailoring content for development teams - Explains how specification can be (and should be) adjusted based on early and on-going developer feedback 2.2 The Care and Feeding of a Synchronized Architecture: To Serve Stakeholders Integrating Architecture Viewpoints - Explains how model elements can be connected to maintain full requirements traceability 2.3 Improving and Adapting the Architecture and SDLC - Describes how we apply continuous SE process improvement and architecture adaptation 3. The Beginning: Opening Moves 3.1 Planning for Uncertainty and Complexity 3.2 Prototyping: unearthing mistakes and misunderstandings 3.2.1 Sprint 0: prototyping the SE process - Summarizes an SE process spike for testing tailored engineering processes 3.2.1 Prototyping capabilities - Summarizes a capability-driven prototyping approach to address high technical risk areas early 4. The Future: Continuous Evolution - Briefly summarizes future direction of continuous evolution in our SE processes and architecture efforts
