Before they started using KaiNexus, JC Cannistraro used their own internal continuous improvement program, in which they tracked improvements with Google Sheets, but at some point this program went dead, flatlining in the number of improvements adopted over time.

In fact, the result was too many opportunities to manage and soon a better solution was needed.
