I should apologize in advance for the fairly non-descriptive term "application." To me, an application consists of features that can be integrated into already existing frameworks. Online examples could include dynamic language translation, e-commerce sections, live chat options, etc. Customer resource management solutions, outsourcing implementation, and improved efficiencies in employee communication would serve as good examples of more general business applications.
The links above should help you conceptualize this further with more specific thoughts. Furthermore, depending on the scope, you may need consulting in addition to application design. Additional information on consulting and methodology can be found in the consulting section.
Feel free to contact me with any questions or further discussion on application design possibilities.
