Forward and Reverse Engineering 
Forward Engineering 
To forward engineer a component diagram, 
  • For each component, identify the classes or collaborations that the component implements 
  • Choose the form for each component 
  • The choice is between source code (a form that can be manipulated by development tools) or a binary library or executable (a form that can be dropped into a running system) 
  • Use tools to forward engineer the models

Reverse Engineering 
To reverse engineer a deployment diagram, 
  • Choose the target that you want to reverse engineer, in some cases, you'll want to sweep across your entire network; in others, you can limit your search 
  • Choose also the precision of your reverse engineering, in some cases, it's sufficient to reverse engineer just to the level of all the system's processors; in others, you'll want to reverse engineer the system's networking peripherals as well 
  • Use a tool that walks across your system, discovering its hardware topology 
  • Record that topology in a deployment mode 
  • Along the way, you can use similar tools to discover the artifacts that live on each node, which you can also record in a deployment model 
  • Using your modeling tools, create a deployment diagram by querying the model 
  • For example, you might start with visualizing the basic client/server topology, then expand on the diagram by populating certain nodes with components of interest that live on them
