Without a launch mechanism, an LMS has
no way to present material to a learner. The launch mechanism
defines a common way for LMSs to start web-based learning resources.
Of course, much content has been launched without
SCORM over the years, but the key difference is that the SCORM
provides a common, well-documented way to launch learning
resources. LMSs and SCOs (Sharable Content Objects) that adhere
to the SCORM can interoperate because of this common launch mechanism.
Other ways of launching learning resources may work only with
specific learning management systems.
