These are rough notes.

I want to share even a little of what we learned while many people in schools are moving online.

I previously summarized the product development cycle briefly, but I rewrote it for internal use from a slightly more abstract level, removed confidential content, and am publishing it here.

In product development, it is very important to design the user experience, clearly define what future state you want to create, and validate it.

I went to RubyKaigi 2019 in Fukuoka. Starting this year, I discussed support for expenses from the company, and four people from the company were able to attend.
