Multiple Instance Levels between Two Systems Integration

There are numerous- instance levels between two systems successfully integrated. Each instance level may have either detectable or undetectable patterns within system development. 

Invisible entities sometimes appear in system integration when two systems integrate without instruction in a new instance level and with a missing performance prediction model. Two methods must specify unique instance-level combinations before changes occur in the current instance level. After the integration model, the new instance level must be reevaluated between the two system platforms. Failure analysis in the different integration modes can diminish output value quality in system integration. A briefcase study or insufficient knowledge about system behaviors produces invisible entities in system integration. System designers must also raise awareness of two systems' local variables, cultures, system functionalities, and characteristics before system integration. 

Global Variables have responsibilities in system integration at different instance levels. Optimized variables produce transparency in internal and external integration systems.
