Kanban (Japanese: 看板, meaning signboard or billboard) is a lean method to manage and improve work across human systems. This approach aims to manage work by balancing demands with available capacity, and by improving the handling of system-level bottlenecks .
The kanban card is, in effect, a message that signals a depletion of product, parts, or inventory. When received, the kanban triggers replenishment of that product, part, or inventory. Consumption, therefore, drives demand for more production, and the kanban card signals demand for more product—so kanban cards help create a demand-driven system.
A kanban board in software development. Kanban can be used to organize many areas of an organization and can be designed accordingly.

In the pull system production orders begin upon inventory reaching a certain level, while on the push system production begins based on demand (forecasted or actual demand). The CONWIP is a hybrid between a pure push and pure pull system.
Material requirements planning (MRP) is a production planning, scheduling, and inventory control system used to manage manufacturing processes. Most MRP systems are software-based, but it is possible to conduct MRP by hand as well.
The use of the term scrum in software development came from a 1986 Harvard Business Review paper titled "The New New Product Development Game" by Hirotaka Takeuchi and Ikujiro Nonaka. Based on case studies from manufacturing firms in the automotive, photocopier, and printer industries , the authors outlined a new approach to product development ...
Marketing research uses the scientific method in that data are collected and analyzed to test prior notions or hypotheses. Experts in marketing research have shown that studies featuring multiple and often competing hypotheses yield more meaningful results than those featuring only one dominant hypothesis. [39] Marketing research is objective ...
The central tenet to DFT is the primacy of customer demand in daily execution of the operation. According to Aberdeen Group, "Demand driven manufacturing involves a synchronized, closed loop between customer orders, production scheduling, and manufacturing execution; all while simultaneously coordinating the flow of materials across the supply chain."
