This is an ongoing urge, to implement technology solutions, to get the benefit of EOS.
1 year into our EOS journey with a team of 30 moving from a starting score of 63 to 88 now, I have found using the tools in their simplest form gets the biggest results, fast. If your leadership team is communicating often and building trust around the EOS methodology within your entire team, then wins come with the basics.
For the HR piece, my personal experience has been an Accountability Chart> GWC> Scorecard with individual numbers, is the foundation. Rocks, GWC reviews and Quarterly Conversations then hold the team accountable and happy. L10's underpin everything to fix issues fast and keep the team engaged.
I am sure a system makes an incremental difference, however, our big wins came from just doing it. Do it first, find a system second. Make it someone's rock when the time comes ;)
FYI we use Asana for all L10's and Rocks tracking. GWC and Quarterly conversations are scheduled in Asana and we use Google Doc template for quarterly conversations and a Google sheet for the GWC review. I use Organimi to store and share our Accountability chart and individual seat "number". We track all numbers in a Google sheet Scorecard shared with the team.
Hope this helps :) Enjoy your journey!
