Customer Goals - Work Progress Should Reflect Metrics Progress
We have the ability to apply metrics to each goal showing progress toward achieving a goal -

but those metrics currently do not impact “Work Progress” on the Customer Goals List:

I suggest that if we are going to allow users to apply a % complete metric to the goal, then that should be reflected on the Work Progress on the Customer Goals List.
Customer Goals List - Work Progress is only impacted by Associated CTAs that are closed, not tasks that closed. also notable - CTAs that are Closed No Success or Closed Invalid will update the work progress as completed (1 CTA:1 Goal) or move the % if there is more than one CTA associated with a customer goal.
I suppose there are other suggestions here, maybe Work Progress should be CTA\Success Plan Progress, and Metrics progress could be an additional field on the Customer Goals list.
