4.4 Requirement Specification Issues

	The requirement specifications for confederations must often be oriented toward the use of existing systems and
	their interfaces.

The properties of the interfaces and their dynamics should be taken into account in the specification.

	As the confederative orientation is common for the soft real-time system developers, it appears that people with
	experience with low-level process control systems could today help a lot at the top-most tier of enterprise
	systems now having confederative architecture also should take part in requirement specification of the large
	systems.

The requirements can now include the new system function types formulated by CEOs:

Enterprise decentralization

Boundaries of divisions

Various forms of in- and outsourcing

CRM

Purchase coalitions, etc

4.4 Requirement Specification Issues

	Many such requirements are feasible only if the enterprise information system is confederated and has an
	appropriate structure.

	Software vendors and system integrators have to change their business strategies as the concept of software
	confederations and e-commerce is a large challenge today.
