Domain-Driven Design: Tackling Complexity in the Heart of Software
Eric Evans - 2003
"His book is very compatible with XP. It is not about drawing pictures of a domain; it is about how you think of it, the language you use to talk about it, and how you organize your software to reflect your improving understanding of it. Eric thinks that learning about your problem domain is as likely to happen at the end of your project as at the beginning, and so refactoring is a big part of his technique. "The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers--it is a future classic." --Ralph Johnson, author of Design Patterns "If you don't think you are getting value from your investment in object-oriented programming, this book will tell you what you've forgotten to do. "Eric Evans convincingly argues for the importance of domain modeling as the central focus of development and provides a solid framework and set of techniques for accomplishing it. This is timeless wisdom, and will hold up long after the methodologies du jour have gone out of fashion." --Dave Collins, author of Designing Object-Oriented User Interfaces "Eric weaves real-world experience modeling--and building--business applications into a practical, useful book. Written from the perspective of a trusted practitioner, Eric's descriptions of ubiquitous language, the benefits of sharing models with users, object life-cycle management, logical and physical application structuring, and the process and results of deep refactoring are major contributions to our field." --Luke Hohmann, author of Beyond Software Architecture "This book belongs on the shelf of every thoughtful software developer." --Kent Beck "What Eric has managed to capture is a part of the design process that experienced object designers have always used, but that we have been singularly unsuccessful as a group in conveying to the rest of the industry. We've given away bits and pieces of this knowledge...but we've never organized and systematized the principles of building domain logic. This book is important." --Kyle Brown, author of Enterprise Java(TM) Programming with IBM(R) WebSphere(R) The software development community widely acknowledges that domain modeling is central to software design. Through domain models, software developers are able to express rich functionality and translate it into a software implementation that truly serves the needs of its users. But despite its obvious importance, there are few practical resources that explain how to incorporate effective domain modeling into the software development process. Domain-Driven Design fills that need. This is not a book about specific technologies. It offers readers a systematic approach to domain-driven design, presenting an extensive set of design best practices, experience-based techniques, and fundamental principles that facilitate the development of software projects facing complex domains. Intertwining design and development practice, this book incorporates numerous examples based on actual projects to illustrate the application of domain-driven design to real-world software development. Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team. A shift in emphasis--refactoring not just the code but the model underlying the code--in combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer. Domain-Driven Design then builds on this foundation, and addresses modeling and design for complex systems and larger organizations.Specific topics covered include:Getting all team members to speak the same language Connecting model and implementation more deeply Sharpening key distinctions in a model Managing the lifecycle of a domain object Writing domain code that is safe to combine in elaborate ways Making complex code obvious and predictable Formulating a domain vision statement Distilling the core of a complex domain Digging out implicit concepts needed in the model Applying analysis patterns Relating design patterns to the model Maintaining model integrity in a large system Dealing with coexisting models on the same project Organizing systems with large-scale structures Recognizing and responding to modeling breakthroughs With this book in hand, object-oriented developers, system analysts, and designers will have the guidance they need to organize and focus their work, create rich and useful domain models, and leverage those models into quality, long-lasting software implementations.

Kanban: Successful Evolutionary Change for Your Technology Business
David J. Anderson - 2010
It will allow you to avoid some likely pitfalls and it will guide you to asking, yourself and your clients, the right questions. Though many people focus on the visualization techniques in Kanban the true value only emerges when you, as a kanban system manager, are apt at noticing the anti-patterns that occur on the kanban board and are able to take appropriate actions. David generously shares his vast experience in this field, with plenty real case scenarios, to the benefit of the reader. After reading this book I toyed with the idea: Would I've changed my approach to coaching my previous clients, in their adoption of agile values and practices, had I read this at the time? Well, I certainly would have, for all of them, and I'm sure it would have meant a smoother change process for the agilely challenged organizations. David provides a comprehensive guide to implementing Kanban in a software development/maintenance environment. Covering the mechanics, dynamics, principles and rationale behind why Kanban is a so promising framework for managing the work of a variety of teams and groups and being an evolutionary-based change management driver. Kanban is the practical approach to implement Lean Software Development, and this book is the practical guide for how to start using Kanban, and how to adapt the system for advanced needs. The book is clear and flowing, even though it covers some quite technical material. I would recommend it to Development managers, Project/Program managers, Agile Coaches/Consultants. It addresses concerns/needs of Novice as well as those already familiar with Kanban and looking for advanced answers. Even if you don't intend to implement a kanban system, there are a lot of techniques and ideas that are easily applicable to any product development/maintenance environment, agile or not. Bottom line, highly recommended.

Remote: Office Not Required
David Heinemeier Hansson - 2013
Moms in particular will welcome this trend. A full 60% wish they had a flexible work option. But companies see advantages too in the way remote work increases their talent pool, reduces turnover, lessens their real estate footprint, and improves the ability to conduct business across multiple time zones, to name just a few advantages. In Remote, inconoclastic authors Fried and Hansson will convince readers that letting all or part of work teams function remotely is a great idea--and they're going to show precisely how a remote work setup can be accomplished.
