Definition of An Application
In application portfolio management, the definition of an application is a critical component. Many service providers help organizations create their own definition, due to the often contentious results that come from these definitions.
- Application software — An executable software component or tightly coupled set of executable software components (one or more), deployed together, that deliver some or all of a series of steps needed to create, update, manage, calculate or display information for a specific business purpose. In order to be counted, each component must not be a member of another application.
- Software component — An executable set of computer instructions contained in a single deployment container in such a way that it cannot be broken apart further. Examples include a Dynamic Link Library, an ASP web page, and a command line "EXE" application. A zip file may contain zero or more software components because it is easy to break them down further (by unpacking the ZIP archive).
Software application and software component are technical terms used to describe a specific instance of the class of application software for the purposes of IT portfolio management. See application software for a definition for non-practitioners of IT Management or Enterprise Architecture.
The art and practice of Software Application Portfolio Management requires a fairly detailed and specific definition of an application in order to create a catalog of applications installed in an organization.

What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
