The only detail I would add is that in 2010 and in 2015, the department's report on plans and priorities also made the commitment to developing a strategic approach, but they still hadn't finalized it in 2016 or 2017. They instead developed regional plans. These regional plans were exactly that. They covered the regions. They looked at the current state of the gaps and possible solutions for those gaps, and we were told that those were being used until the strategic approach could be developed.
On November 28th, 2017. See this statement in context.
