本文介绍了一种通过组件视角来构建IT服务堆栈的方法。该堆栈采用分层方式展示IT的所有方面，每一层都有负责提供服务的组件，并且这些组件会使用同一层或下一层提供的服务。

IT Services Stack: collaboration experiment

It is not always easy for an enterprise IT architect to keep scope and hold the complete picture. As we have several architects with different competences I felt the urge to develop an IT Services Stack. The IT Services Stack is a picture of a layered view on all aspects of IT from a component perspective.

I have this picture always at hand during every meeting. And I use the picture to address subjects to the most competent architects.

The idea behind the view is the layering of services delivered by components. At every layer components are defined that play a role in delivering services. Components on one layer make use of services delivered by components on that same layer or by components on the next lower layer. Those are the constraints I applied to construct the model. Don't view the layers as a logical top-down flow, but as a way of grouping and encapsulating cohesive components.

The top layer is the business layer. The next lower layer is the process layer. These two business oriented layers do not only imply externally visible business and processes (like transportation of people by trains), but also internal business and processes. E.g. the IT department delivers services to other departments. This is the IT-scoped business defined at the top level layer. And the processes of the IT business are e.g. software development processes the require development tools (IT-business applications).
