Kanban
Kanban makes work visible by moving cards across columns that stand for stages, from waiting through in progress to done. It came off Toyota's production lines in the 1940s and reached software through David Anderson in 2010. Capping how many cards may sit in a column at once is the mechanism, not the board itself.
Also called: kanban board, personal kanban
Where it goes wrong
Nearly every task app ships the board and leaves out the work-in-progress limit, which is the part that changes behaviour. A board with no limit is a list turned on its side. It also has no clock: a card can sit in the in-progress column for six weeks without the column ever mentioning it.
Diarized schedules the work you already keep in a to-do app into the calendar you already use, and shows you why every block landed where it did.
