Pull System
Definition A method of controlling the flow of
resources by replacing only what has been
consumed.
4
Push System
Definition A method in which resources are
provided to the consumer based on forecasts or
schedules.

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

9
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

10
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.

11
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.

12
TYPES OF KANBAN
  • Primary Kanban
  • Supply Kanban
  • Procurement Kanban
  • Subcontract Kanban
  • Auxiliary Kanban

13
KANBAN CARDS
  • The core functionality of a Kanban card is to
    visually convey a work items 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 teams
    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
  • Facilitate handoffs between team members as the
    work progresses through different stages in the
    teams process
  • Document critical information
  • Record important work attributes and metrics that
    you can use later to help improve your workflow

14
CORE ATTRIBUTES OF A KANBAN CARD
  • As Kanban emerged as a system in knowledge work,
    the kanban card came to represent an individual
    work item. These pieces of work are typically
    displayed in the form of sticky notes on a
    whiteboard that uses lanes to show the steps in a
    teams process.

15
FACE OF KANBAN CARD
  • The face (or front) of a Kanban card presents
    details that are relevant to the team, such as a
    unique identifier or title, a brief description
    of the work, a rough estimate of the size of the
    work, and whos been assigned to it.

16
BACK OF A KANBAN CARD
  • As a Kanban card moves through the workflow, team
    members can use the back of the card to record
    applicable metrics (e.g., start date, blocked
    days, blocked location, finish date, and lead
    time)

17
CONCLUSION
  • But why Kanban?
  • because
  • it helps in visualising the system and expose
    problems
  • it allows us to evaluate the impacts of process
    changes
  • it allows us to identify bottlenecks and
    alleviate them
  • it allows us to establish trust in the process
  • it helps us to maintain a sustainable pace with a
    sustainable throughput
  • you need to relax and Kanban advocates just that!
