DOD's On-the-Job Training Tool

I work for a civilian agency and, aside from the FAC-C program, we have no formal training. A few of us are looking to put something together and are exploring what other agency's (especially DOD) are doing. One thing we came across was the OJT Tool that was recently introduced. Does anybody here have experience with this as a training/development tool? Has it been effective or was it largely treated as a "check the box" activity? I'd be interested to hear thoughts and opinions on the merits of the tool.

Otherwise, anything else out there that we can benchmark? Thanks!
