I was listening to show number 426 on dotnetrocks: Rob Boucher on Application Architecture Guidance! They mentioned the Patterns And Practices Application Architecture Guide 2.0, this guide is available for free on codeplex.
Although it is a Microsoft technology centric guide, there should be chapters for every developer in your group.
Here is one example from the book
Key Design Principles
When getting started with your design, bear in mind the key principles that will help you to create architecture that meets “best practices,” minimizes costs and maintenance requirements, and promotes usability and extendibility. The key principles are:
- Separation of concerns. Break your application into distinct features that overlap in functionality as little as possible.
- Single Responsibility Principle. Each component or a module should be responsible for only a specific feature or functionality.
- Principle of least knowledge.** A component or an object should not know about internal details of other components or objects. Also known as the Law of Demeter** (LoD).
- Don’t Repeat Yourself (DRY). There should be only one component providing a specific functionality; the functionality should not be duplicated in any other component.
- Avoid doing a big design upfront. If your application requirements are unclear, or if there is a possibility of the design evolving over time, avoid making a large design effort prematurely. This design principle is often abbreviated as BDUF.
- Prefer composition over inheritance. Wherever possible, use composition over inheritance when reusing functionality because inheritance increases the dependency between parent and child classes, thereby limiting the reuse of child classes.
The nice thing is that each chapter has a resource section at the bottom so that you can dive deep into a specific topic mentioned in the chapter itself. This is great stuff and I recommend that you check out this guide. You also might want to listen to the dotnetrocks podcast about this guide: http://www.dotnetrocks.com/default.aspx?showNum=426
