It's time for change - after 30 years, DCI has risen to complete the vision of object-oriented programming!
Aiming at no less than a paradigm shift, Lean Architecture uses a modern approach to software design, while embracing refreshing new insights of Lean and Agile. Giving a down-to-earth view of Agile requirements and the often-ignored relationship between requirements and architecture, this book goes beyond the fashionable idea of User Stories, and shows you how to employ Use Cases in a lightweight, incremental, Agile way. The authors detail the DCI (Data, Context and Interaction) architecture paradigm and show how DCI succeeds where object-oriented programming languages alone have failed to integrate software design with the end user's understanding of the overall business structure.
However, this is not a methodology book, but a book which focuses on code, with plenty of code examples. Topics covered include: Agile production, Stakeholder Engagement, Organizational issues, Scala/Python/Java implementation of the DCI account example, Qi4J and much more.
Renowned software architecture expert James Coplien and agile requirements expert Gertrud Bjørnvig share their expertise to give you concrete design advice that will help you:
- Create software that builds on your end-user mental models rather than design methodologies
- Write software that can directly be verified against behavioral requirements
- Organize - so that all your stakeholders support each other
- Support rapidly changing feature code in stable domain code to help embrace change
Lean Architecture casts a new light over important aspects of software development that have been marginalized or forgotten by the agile movement – it will help you find your own path.
