What is Kanban and how It helps big companies?

Have you heard Kanban? What about Trello?

Kanban is a good and famous project management methodology that helps startups or companies to have their task visually,
While scrum gives structure to the team and schedule.

Kanban and scrum are both considered project management methodologies that complete tasks in a short period of time.

The best example of Kanban is Trello. Trello is a web-based kanban.

The point of using kanban is that the tasks must be continuous, and it is not limited by time at all.

But, instead, in the scrum, the goal is to move all to-do or doing tasks to the Done section in a fixed amount of time, which is called "Sprint".

Companies like Toyota use kanban, and you can read more about their approach here.
