TPM - Focused Improvement Pillar Information

I am looking to learn more about TPM and more specifically the focused improvement pillar. Does anyone know of any good resources out there? I am curious to learn about how the FI pillar is organized and some detail behind it so that I can compare how we run our continuous improvement efforts at my plant. I'm looking to find out how we might be able to take our work to the next level.

Any information is appreciated.
