We were very impressed with Michael, very happy with the work.  He was very thorough, and we liked his approach. We had sort of tried to do the process on our own, and came to the conclusion that none of us were real experts, and we could use some help with this.  I guess the thing that impressed me most was the thoroughness when it came down to the spreadsheet he was using to track all the various requirements.  It was very impressive in terms of covering things we would not necessarily have thought were issues. We were kind of stumbling through the process, and we appreciated his methodology.  He knew the best was to go through the process, and at the same time he was open to being flexible and to consider our comments and adjustments.
