    Study Notes

    Process Mapping

    • Process mapping visually represents steps in a process
    • Purpose: Understand workflow, identify inefficiencies, standardize procedures, pinpoint bottlenecks, and support continuous improvement initiatives by distinguishing value-adding and non-value-adding activities

    Process Mapping Symbols

    • Oval (Terminator): Represents start or end of a process
    • Rectangle (Process/Activity): Represents a task or activity
    • Diamond (Decision): Represents a decision point (yes/no or conditional path)
    • Arrow (Flowline): Indicates process flow direction between steps
    • Parallelogram (Input/Output): Represents data or materials entering or leaving the process

    VA, NVA, and NNVA Activities

    • VA (Value-Adding Activities): Directly create value for the customer
    • NVA (Non-Value-Adding Activities): Consume resources without adding customer value
    • NNVA (Necessary Non-Value-Adding Activities): Necessary due to legal, regulatory, or business requirements, but do not directly add value

    Lean Wastes (TIMWOOD)

    • Transportation: Unnecessary movement of materials/products
    • Inventory: Excess raw materials, WIP, or finished goods
    • Motion: Unnecessary movement of people/equipment
    • Waiting: Idle time due to delays in the process
    • Overproduction: Producing more than required or too early
    • Overprocessing: Performing unnecessary work or adding features that don't add value
    • Defects: Production of defective items requiring rework/scrapping

    Primary Questions for Process Improvement

    • Is this step essential to the process?
    • Does this activity add value for the customer?
    • Can this activity be eliminated?
    • Can this activity be automated or streamlined?
    • Is there any redundancy in this step?
    • Are there delays associated with this step?
    • Does this step require rework or corrections?
    • Can the layout or flow of this step be improved?
    • Is the correct amount of resources allocated here?
    • Can this activity be performed faster or more efficiently?

    Secondary Questions for Process Improvement

    • Who performs this step, and are they the right person/team?
    • Are the tools used in this step appropriate and effective?
    • Is this step prone to errors or defects?
    • Is there a way to simplify this activity?
    • Can this step be consolidated with another?
    • Is there a clear understanding of why this step exists?
    • Are there any bottlenecks related to this activity?
    • Can technology be introduced to improve this step?
    • How often does this step occur, and is it aligned with demand?
    • Does this step comply with all necessary regulations and standards?

    Cause and Effect Diagram (Ishikawa/Fishbone Diagram)

    • Used to identify, analyze, and visualize potential causes of a problem/effect
    • Breaks down root causes into smaller, manageable parts
    • Facilitates brainstorming and collaborative problem-solving
    • Aids in quality control and continuous improvement

    Cause and Effect Diagram Structure

    • Effect (Head): Represents the problem or issue
    • Main Categories (Bones): Broad areas where causes may originate (People, Methods, Machines, Materials, Environment, Measurements)
    • Sub-Causes (Smaller Bones): Specific causes falling under main categories
    • Arrows: Connect each cause to its category and the central spine, visually displaying cause-effect relationships

    Creating a Cause and Effect Diagram

    • Define the problem
    • Assemble a team
    • Identify main categories
    • Brainstorm sub-causes
    • Construct the diagram by drawing the "spine" and adding branches for main categories and sub-causes
    • Analyze and prioritize causes

    Causal Loop Diagrams (CLDs)

    • Visual tools for modeling and analyzing feedback loops and interdependencies within dynamic systems
    • Used to identify how variables interact over time, creating feedback dynamics

    Causal Loop Diagram Purpose

    • Visualize and understand feedback structure of a system
    • Identify dynamic behaviors (growth, decay, oscillations, stabilization)
    • Provide insights for intervention or improvement

    Causal Loop Diagram Principles

    • Feedback Loops: Reinforcing (amplifies change), Balancing (counteracts change)
    • Variables and Arrows: Variables represent system elements, arrows indicate causal relationships between variables
    • Polarity: Positive (+) change in one variable causes corresponding change in another, Negative (-) change in one variable causes opposite change in another
    • Delays: Time delays within feedback can significantly impact system behavior
