Hello, last few month i'm trying to move my team from Trello to Jira products.
At first, i tried to reproduce our Trello's Kanban board with similar flow, then realized - Jira have so many options and maybe there is a better way to make simple, clear and clean development flow?
Currently i have this one:

It worked OK for Trello, since there is no much tools to indicate or track things. But in Jira there is 2 stages which i dont like: Ready for review and Ready for testing.
Both are sort of a backlog for teams which make a testing and a review. At the same time statuses 'In review' and 'in test' indicate to everyone else in a company what a tester or a reviewer is actually working on something right now.
Maybe Jira offers a tool to keep 1 column/status for each activity?
1. The tasks needed to check (scope or a backlog)
2. The tasks someone working on right now.
Both activities cant be in a separate boards/projects, as there are managers who need to see whole picture of a development. I also need to collect the data how well reviewing and testing going, they could bottleneck whole production and i want to understand earlier do i need to add more people or change processes within those 2 departments.
How you guys handle those stages? Plz share your wisdom
