Smartsheet is a simple to use project management tool that mirrors what people are already using: spreadsheets. While not as 'pretty' as other competing tools out there, I have found that implementing Smartsheet works because people actually use it with minimal training. Unlike a lot of other tools that require a time consuming 'implementation' phase to get up and running, Smartsheet is so intuitive that people just use it. At the end of the day, a tool someone actually uses has value. Lots of other tools are better in a design/functionality/flexibility sense, but in the one metric that counts: end-user adoption, Smartsheet has them all beat.
