I haven’t heard of SIMM Levels before this presentation but they appear to be interesting statements about maturity.
Talking about service quality, “You can’t mediate faster”.
ISO9126 was also mentioned:

What the presenter is downplaying is the duplication of skill that is required to do between two different sets of editors and runtimes. If you are a team that needs to get their services out the door in a reasonable time, I maintain my recommendation to stay with modules at all times if possible.
