Reason 4: Team Specialists Don't Always Work in Integrated Ways - I

Organizations employ very specialized teams and approaches to product and system development yet fail to integrate them with each other. 

To improve efficiency, many organizations have broken down the product development process into separate system components developed independently, For example, components of a software product include the user interface, the help system, and the written materials. Typically, these components are developed by separate individuals or teams. Now, there is nothing inherently wrong with specialization. The difficulty arises when there is little integration of these separate components and poor communication among the different development teams.

Often the product development proceeds in separate, compartmentalized sections. To an outsider looking on, the development would be seen as depicted in Figure 1-2.
