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
