KAN BAN

 

Kanban is one of the agile project management methodologies that uses visual workflows to keep tasks organized and moving forward. The name Kanban comes from the Japanese words Kan and Ban, which means in combination: a marked board. It derives from the production control method introduced in the fifties (1950s) in Japan by Taiichi Ohno.

Historically, it was about optimizing production by counting and describing every element involved. The term Kanban originates from Toyota’s “just-in-time” production system, which means doing:

• “only what is needed, when it is needed, and in the amount needed.”

Kanban belongs to the so-called pull strategy, which means that each completed step involves the previous one in queue.

For example: completion of the building stage triggers the testing stage.

Another more detailed example: if the last packet of coffee is in stock, a Kanban Board (order request) is created for the purchase of an additional packet, the purchase should occur when the last one coffee is taken from the warehouse.

This is what we call the optimization of the storage process and the purchase of goods at the right moment. These processes are based on the continuous visualization at Kanban Boards and analysis of data, which is filled in, with each movement in the flow (change step). The best results are achieved in small, agile teams where the entire workflow can be drawn.

The purpose of Kanban is to:

1. Eliminate wasteful work, inconsistencies
2. Make the process more transparent, efficient and teams more productive
3. Limit Work In Process – one person or team works on one task until they complete it
4. No inactivity but no overload
5. No unnecessary technological and control operations
6. Fast, short and specific feedback

Benefits: 

• Transparency, team members can see and understand who works on which task, what is being worked on, and when the task will be completed.
• Work is divided into smaller and more manageable tasks
• Allows for focused and more efficient work
• Fits a wide range of applications

 

Disadvantages: 

• For well-organized team members
• The out-of-date Kanban Board state may cause chaos
• The Kanbard Board must be well and clear designed, sometimes boards are overcomplicated
• There is no timeframes, so in some cases it may be problem with delivery on time

 

The simplest Kanban board consists of three columns:

• TO DO
• IN PROGRESS
• DONE
