Thanks for that. That's my understanding of TBIPS as well.
I would submit that Ms. Daly would largely agree with your statement and your summary, as she described TBIPS as where:
...team members pre-qualify contractors and companies like GC Strategies and place them into the government-wide purchasing catalogue. No manager, DG or minister in the federal government is permitted to buy IT pro services from any other source but this TBIPS-designed catalogue. There may be exceptions unknown to me.
That was her understanding of the program. Is that a fair assumption that you would agree with?
