A result of adopting an open systems architecture is that it:
Facilitates interoperability.
Contributes to a better realization of architecture scalability.
Allows the integration of proprietary components.
requires multi-disciplinary IT resources to support.
Serves as a foundation for vendor discounts on volume hardware/software sales.
Open systems are those for which suppliers provide components whose interfaces are defined by public standards, thus facilitating interoperability between systems made by different vendors. In contrast, closed system components are built to proprietary standards so that other suppliers' systems cannot or will not interface with existing systems.

Create a tailored training plan based on the knowledge you already possess.
