my guess on "her involvement" in her material is that it varied greatly over time. while working with A&S, it seems like she had more involvement and engagement with the producers. especially with The Boss. Val has mentioned how they worked with Diana at that time to get a sense of who she was, what she was wanting to express, etc.

i believe Bluebrock and some others have stated that during the RCA era, Diana was more or less just going through the motions. maybe with WDFFIL she was much more personally involved because it was her first lp as the producer and it was the first after motown. she wanted to prove that she could do it. after that, like with SE, it was just another lp in order to meet contractual requirements. her attention had shifted more to other business ventures and setting herself and her family up financially for the future. on Ross 83, you can practically hear her lack of involvement in her lazy vocals. and yes, fans have stated how the EA sessions were troublesome at best

after WO, it seems she reinserted herself back into her recording career. for Force, Take Me and Every day, she seems to have been actively engaged with the producers, finding material that was worthwhile. although her relationship with the motown label was lacking. also her box set was a total waste and then her personal problems interrupted the whole Every Day project
