PULL SYSTEM

Definition: A method of controlling the flow of resources by replacing only what has been consumed. Pull Signals Pull Process Material At Operator Manpower WASTE

PUSH SYSTEM

Definition: A method in which resources are provided to the consumer based on forecasts or schedules.

PUSH VS. PULL

PUSH SYSTEM Make all we can just in case. Make what’s needed when we need it • Production Approximation • Anticipated Usage's • Large Lots • High Inventories • Waste • Management by Firefighting • Poor Communication

PULL SYSTEM • Production Precision • Actual Consumption • Small Lots • Low Inventories • Waste Reduction • Management by Sight • Better Communication

KANBAN Kanban means “card” or “visible record” or “signboard” in Japanese & refers to cards used to control the flow of production through a factory. KANBAN is a PULL System

FUNCTION OF KANBAN The key objective of a Kanban system is to deliver the material just-in-time to the manufacturing workstations, and to pass information to the preceding stage regarding what and how much to produce. A Kanban fulfills the following functions: Visibility function: The information and material flow are combined together as Kanban's move with their parts (work-in progress, WIP). Production function: A function which indicates the time, quantity, and the part types to be produced Inventory function: Which measures the amount of inventory

THE KANBAN METHOD The Kanban Method is an approach to incremental, evolutionary process and systems change for organizations. It uses pull system as the core mechanism to expose system operation and improve the system. The Kanban Method is rooted in four basic principles: Start with existing The Kanban method starts with existing roles and processes and bring continuous changes to the system. The Kanban method is a change management method. Agree to pursue incremental, evolutionary change Incremental and evolutionary change is the way to make system improvements and make them stick. Sweeping changes may seem more effective but have a higher failure rate due to resistance and fear in the organization. Respect the current process, roles, responsibilities and titles The Kanban method seeks to drive out fear in order to facilitate future change. It attempts to eliminate initial fears by agreeing to respect current roles, responsibilities and job titles with the goal of gaining broader support. Leadership at all levels Acts of leadership at all levels in the organization, from individual contributors to senior management, are encouraged.

KANBAN PROPERTIES Kanban is based on five core properties: • Visual workflows • Work in progress (WIP) limits • Enhanced workflows • Agreement on process policies • Data-driven collaborative improvement.

TYPES OF KANBAN • Primary Kanban • Supply Kanban • Procurement Kanban • Subcontract Kanban • Auxiliary Kanban

KANBAN CARDS The core functionality of a Kanban card is to visually convey a work item’s progress as it flows through a system or process. While not intended to replace the need for conversation, using cards on a Kanban board as the team’s central information hub can reduce time spent in status meetings, introduce more high-value collaboration opportunities and improve overall efficiency. Kanban cards can help teams: • Gain a quick understanding of work item details Category:Kanban Category:Pull Production Syteam Kanban Category:Eng.Adnan Ali Category:Pull System Kanban
