Hi. I'm Henshaw of Rule 37. AMA.
The project was highly successful from an R&D perspective, but it never flew in space for a variety of reasons. SOme of those were related to a lack of funding and/or national commitment to spacecraft servicing, and some were due to us not executin the program as expeditiously as we probably should have.
If there are unclear boundaries between responsibilities, things will fall through the gaps when one group assumes another will take care of something.
"at a project's beginning, define rules such as 'if component X explodes, it is team ABC's fault'".
