Keynote: Strategic Design & Responsibility Traps
As software development leaders, we need to think more strategically. Some design decisions affect the trajectory of the whole project or even the organization. These decisions arise in early chartering and throughout development, and they are about much more than architecture. In this keynote speech, recorded at the DDD eXchange 2009, Eric will examine these issues through the lens of the Strategic Design principles of domain-driven design, which systematize a few critical practices some successful teams do intuitively.
It is common for skilled teams to deliver software they are not proud of, due to compromises with legacy designs. Others toil for years, producing a platform that is never used to good advantage. These are strategic failures. On the other hand, there are projects with a direct explanation of how the software contributes to business goals. There are projects where designers work with a realistic view of the context of their development within the larger system, allowing them to maintain design clarity and integrity. These are strategic successes. Winning strategy starts with the domain.
Two domain-driven design principles, "Context Mapping" and "Distilling the Core Domain", help you see your strategic situation more clearly and approach strategic design decisions more systematically. These techniques require extensive interaction with domain experts as well as the leaders of the organization, in discussions broader than functional requirements. They sometimes lead to priorities quite different from our most comfortable notions.

Eric Evans Domain Driven Design Hands-On Immersion WorkshopEric Evans' 4-day Domain Driven Design Hands-On Immersion Workshop will teach you how to put the domain model to work. This intensive course will teach you how to strike a healthy balance between digging into your subject matter and addressing technological issues, which, while unavoidable, cannot be allowed to dominate the development process for commercially viable systems. We weave together lecture, discussion and classroom exercises, including hands-on coding projects. In discussions, you will have the opportunity to discuss your own experiences and relate your own work to the principles and techniques presented in the class. To find out more, please go here
Greg Young's CQRS, Domain Events, Event Sourcing and how to apply DDD
This 3-day CQRS course covers Domain Events, Event Sourcing and how to apply DDD. Join to learn all about system building and architectures with Domain Driven Design. The largest problem many run into with Domain Driven Design is in getting the abstract concepts implemented in a concrete way. Many of the stereotypical architectures people use actually make it impossible to apply DDD. Greg's course will help you avoid this. To find out more, please go here
Udi Dahan's Advanced Distributed Systems Design with SOA
This very intensive 5-day workshop will help you take the pain out of designing large-scale distributed systems. New technologies make it easier to comply with today’s communications and security standards, but they won't magically provide you with a robust and scalable system. Join Udi for a course packed with the wisdom of companies like SUN, Amazon and eBay. Tried-and-true theories and fallacies will be shown, helping you to avoid costly mistakes. Communications patterns like publish/subscribe and correlated one-way request/response will be demonstrated, in conjunction with advanced object-oriented state management practices for long-running workflows. If you enjoy deep architectural discussion, join! To find out more, please go here
