Kanban System | Glossary

Definition:

The term  “Kanban” is a Japanese word which means “signal-card” in English and it invented by Industrial engineer “Taiichi Ohno” in order to improve efficiency at Toyota.

In manufacturing environment, this card signals upstream process to produce more.  The Kanban System used as a simple planning system, in which one can control and manage work and inventory at every stage of production optimally. Kanban is a concept identified with Lean and just-in-time (JIT), it is used in the planning which  clearly tells you

  • what to produce?
  • when to produce it?
  • how much to produce?

in a systematic way of approach, that will match inventory with demand and achieve higher levels of quality and throughput.

Application of this in knowledge work, especially in software engineering would enable a sustainable pace and find an approach to introduce changes with minimal resistance.  Kanban System helps to change the focus from a push to meet demand forecasts to a pull generated by actual demand.

Data Flow Diagram | Glossary

Definition:

Data Flow Diagram (DFD) is a graphical representation of the “flow” of data through a system creating an overview without going in to detail which can be elaborated. DFD diagrams helps in collecting and understanding requirements as well as designing systems.

DFD is visualization technique which enables communication and collaboration of key information. Shows what kind of information will be input and output from the system, how data flow through the system and where data will be stored. DFD helps users to visualize how the system will operate, what the system will accomplish and how the system will be implemented.

This modeling helps in developing any system, visualizing major steps and data involved in system processes in a top-down approach to system design also known as Bubble Chart.
