Kaizen Week 2015 (Part 1)


Hello! Yoshiko here, reporting on our annual Backlog Kaizen Week. Nulab held this year’s Kaizen Week from May 11-15.

About Kaizen Week

Kaizen in Japanese means improving, changing for the better. During this week, we only focused on making improvements to Backlog. For this year’s Kaizen, all of Nulab’s developers (not just from the Backlog team, but also from Cacoo and Typetalk) joined. This year, we successfully improved 60 issues!!

It wasn’t easy, but we did it!


During Kaizen Week, we shared our statuses on Typetalk and during daily morning meetings. I really enjoyed it because I don’t usually get many chances to talk with Nulabers in other teams or locations. Even for the developers who just joined Nulab recently, I believe it was a great opportunity to get to know about Backlog.

To improved 60 issues in 5 days, it’s actually a very impressive achievement! This year’s issues were harder to deal with than those from last year–which, incidentally, was our first Kaizen Week.

On the last day, we had a debriefing (and celebration). We told ourselves that we would treat ourselves to sushi if we resolved 100 issues. We only reached 60, but we had sushi anyway. 😆  A big thank you to our dear co-founders, Masa, Toshi and Shin!! We will keep holding Kaizen Week every year. We also plan to start Kaizen Week for Cacoo and Typetalk.
