But I don't agree with your further trick:

If there are any conflicting EA principles, then those need to be reviewed and/or eliminated. We don't need to dot every i and cross every t! IMHO, if we have reached a situation where we have too many principles and some of them conflict, it is probably because we are going into too much detail, or we haven't got the correct top-down approach, i.e. flowing from the EA through to TA, IA, DA, BA, etc. I might have completely misunderstood you, and if so would like some examples, if you could elaborate...
As there should be no conflicting principles, I see no point in principles being prioritised either. Though, I have no issue if they are.
AspiringEA, we have had a few excellent discussions on Architecture Principles in this group before. I can refer you to two I remember, titled: "EA value measures ? who cares?" and "Can the principles of enterprise architecture be inherited from a Saas solution?". You might find some more, if you look back through the archives in this group.
Kind regards,
Joseph
