His presentation was organised as a talk about common problems and symptoms of those problems, with audience voting on what hurts them the most. From my perspective, it was a very effective way to see problems of other teams and definitely raised the awareness of some of these issues.

The goal of part 3 of this series is to compare and contrast the Onion Architecture with traditional layered architecture. I will flatten the Onion Architecture to see what it looks like compared to traditional layered architecture, and I will force the layered architecture into an onion.

It stands to reason, then, that an organization interested in adopting agile practices might also be interested in PMI’s OPM3, ISO or Capability Maturity Model® Integration (CMMI) as a means to achieve that excellence. While I have seen some organizations that are trying to implement agile and a PMI model at the same time, none are doing it successfully. Last year, in fact, I observed two very large companies that had simultaneous internal initiatives to utilize agile and CMMI. At both companies, each group saw the other as competition.

It is that simple. Everyone has standards. However, some standards are more important than others. When developing your own standards you should consider those standards that are greater than you first. So your standards should extend those standards that are defined above your position.

 As a side note, you will find that I tote maintainability as a hugely important factor. To me, maintenence is the biggest comsumption of development resources whether it be through bug fixes or adding new features.

A common test code smell, amongst others, is the duplication of assertion logic which can reduce reusability, readability and thereby obscure the specific verification intention of tests. To subdue this special smell several patterns and refactorings are available to acquaint the test code with the DRY principle. So in this blog post I'd like to set the focus on some of the aspects of the Custom Assertion pattern, by showing how to create custom PHPUnit assertions, which attacks the above mentioned smell and its retroactive effects with a huge antiperspirant flagon, while also providing the chance to build a customer friendly and domain related test vocabulary.

I've found that it leads to more maintainable applications since it emphasizes separation of concerns throughout the system. I must set the context for the use of this architecture before proceeding. This architecture is not appropriate for small websites. It is appropriate for long-lived business applications as well as applications with complex behavior. It emphasizes the use of interfaces for behavior contracts, and it forces the externalization of infrastructure. The diagram you see here is a representation of traditional layered architecture. This is the basic architecture I see most frequently used. Each subsequent layer depends on the layers beneath it, and then every layer normally will depend on some common infrastructure and utility services. The big drawback to this top-down layered architecture is the coupling that it creates. Each layer is coupled to the layers below it, and each layer is often coupled to various infrastructure concerns. However, without coupling, our systems wouldn't do anything useful, but this architecture creates unnecessary coupling.
