Overview
Kanban Zone is a visual process management tool built around the Kanban method. Teams use it to see all their work on one board, find where work gets stuck, and change how they deliver. Contrive Solutions built the product on the MERN stack. It now serves more than 50,000 active users.
The challenge
- Map real workflowsTeams needed one place to map how work actually moves, from first request to delivery, not a fixed template.
- See every initiativeThe map had to show all initiatives at once and stay easy to edit.
- Improve with dataTeams needed enough data to analyse their process and improve it.
What we built
- Visual workflow builderTeams design boards that match their own process instead of a fixed template.
- Process analysisViews that show how work moves through each stage, so teams can spot slow steps and fix them.
- Initiative visibilityOne view across all initiatives, so managers see every team's work without asking for status updates.
- Team collaborationShared boards where everyone on the team works from the same picture.
Results
- 50,000+active users on the platformWe built the core application, scaled it to this size and still support its development.
