ShawnCycle ,

Excellent episode on KATALYST for Ops Leaders

I really liked a recent episode that described Katie’s KATALYST framework for Transformational leadership. It describes 8 competencies that Operational Excellence and other Transformational leaders should aspire to get better at. Many of these I found myself agreeing with during the episode and realized that I have focused on them without crystallizing them as Katies has done. I can see using this frame work to improve myself and as a coaching mechanism for my team and leaders that I coach. Clearly I might be biased since Katie also referred to our upcoming episode together, but I really liked this episode with that reference not with standing. I’m looking forward to how Katie connects and explores this topic in future episodes. If you’re newly looking into this podcast, I would highly recommend it to anyone trying to get better as a leader.

Always fun

Especially when Dickson is on the show. All his spontaneous comments, chuckles…

Addicting, despite being Eucational

I really listen to hear Vincent’s puns and asides, such as when he learned that horses are closest to bats biologically he exclaimed “ you mean Pegasus was real?“. How can one not listen after that! And the science is OK too.
