Interesting discussion in this recent report from the US DOT regarding Commercial-Off-The-Shelf (COTS) vs. Custom mobile app development in section 3.3.2, page 6:
"Those interviewees from agencies that have put forth the effort to build custom mobile applications all concluded that, had they known then what they know now, they would have foregone application development altogether, and used a COTS product from the beginning."
