KanBan2Go is a free productivity and organizing app I learned about from Richard Byrne at Free Technology for Teachers. kanban2go is a visual, online task management service. It's simple and easy to use and accessible online from computer, tablet or smartphone (mobile site, not app).
There is a To Do list that is where you put the tasks in the order of priority. The In Progress board is for the tasks that you are actively working on and the Done board is for the completed tasks. This is all done in a visual manner instead of just text and priority codes.
You can collaborate with others on the tasks and sync your tasks with Google Calendar, iCal, Outlook, Evernote and share your boards through email or on Twitter. This is a great resource for teachers, administrators, and students to use to organize themselves and to do collaborative planning on projects.
Here's a video about kanban2go:
Kanban is a Japanese word that means billboard. Companies use Kanban boards to organize, communicate, prioritize and manage what they do. United Technologies uses Kanban's as part of it's ACE (Achieving Competitive Excellence) program and I used it when I worked at Pratt & Whitney and Sikorsky. Using Kanban's allowed us to work more efficiently, be better organized, let everyone know what was going on and where, and keep things working. We also used Kanban cards to create efficient workflows of parts, supplies, and materials throughout the plant.
This method can also be used in education - label things, create boards that communicate better to staff and students, and much more.
