Erwin Training was developed to support the IDEF1X and IE modeling standards. The useof various levels of models within the IDEF1X method can be very helpful in developing a system. General model levels are outlined in the IDEF1X standard and are presented next. In practice, you may find it useful to expand or contract the number of levels to fit individual situations.
