First, System test plan is prepared to make our self ready to prepare the entire system which is being developed from the scratch. System test plan is prepared only if the application or product is completely new. And the application or product need to undergo all type of testing like Functional, Performance, Load, Certification, UAT etc.
Second, Integration test plan is prepared if a product or application being developed by several team or several developers and if one complete module output is going to be as a input for another module, then this Integration Test Plan will be useful to plan accordingly. So when two systems being integrated the possibilities of issues are like software compatibility, input variable map etc. So these needs to be tested completed when its integrated. Hope its clear now.
Berkland's claimed "accuracy rate" is also incomplete. The societal value of any prediction method depends not only on its success rate (the proportion of total predictions that are successful), but also on the false alarm ratio (the proportion of predictions that are false), and on the hit rate (proportion of all events successfully predicted), or its inversion, the number of earthquakes missed.  These cannot be determined without knowing about all of the predictions made, which Berkland does not document.
The Toyota RAV4 was another finalist with a cavernous cabin, but it, too, left something to be desired. First, the good. Like the Honda, the Toyota has a large cargo area with a low lift-over height; it even has underfloor storage, though the compartment is rather small and hard to reach, as it’s located by the rear seat backs. The rest of the cabin is also relatively spacious, even if sightlines out the windows are on the claustrophobic side. Although the functionality of the RAV4 is strong, once you start looking past them, the interior starts to fall flat compared to the competition. Fit and finish is only so-so, and overall quality is lacking. “I can’t seem to figure out what these trim panels on the door are supposed to look like,” Markus said. “Varnished driftwood with glitter? Straight-grain carbon fiber? They’re just weird.”
