SCORM, which stands for Sharable Content Object Reference Model, was created in 2001 to solve a real problem: training content built in one system could not run in another, tracking was inconsistent and organisations were wasting money rebuilding the same content for different platforms. SCORM standardised all of that. It gave the L&D world a common language for packaging, delivering and recording course completion.
That was a genuine breakthrough and the reason SCORM is still everywhere is that it solved its original problem well.
62% of businesses still use SCORM in their LMS and the primary reasons are LMS compatibility, long-standing use and technical stability. These are not bad reasons. They are practical ones and L&D buyers who dismiss them are underestimating the institutional inertia that any replacement strategy has to account for.
