Another benefit of SOA is that it lends itself well to agile software development methodologies. The fact that complex software systems are broken down into services with small, manageable units of logic fits well with an iterative process and how tasks are allocated to resources.
You may also find that having developers take on tasks is easier with SOA because each task can be made to be manageable in size and more easily understood. Although this is beneficial for any developer, it is particularly helpful for junior developers or those who are new to a project and may not have as much experience with the functionality and business domain.
