Simple Process Mapping Techniques Simple Process Mapping Techniques Presentation Transcript

  • Simple Process Mapping Techniques
  • Why Process Mapping?
    • Process mapping:
      • Visually represents the work process
      • Identifies problem areas and opportunities for process improvement
      • Provides a common understanding of the entire process and specific roles and contributions of process participants.
      • Before you can improve a process, you must understand it.
    • Process maps are good for:
      • Streamlining work activities and telling new people, as well as internal and external customers, "what we do around here."
      • Helping in the effort to reduce cycle time, avoid rework, eliminate some inspections or quality control steps, and prevent errors.
    • Process maps are a great problem solving tool
      • Helps us determine what is the problem/what it is not
  • What is a Process? A process converts inputs into outputs
  • How to Create a Simple Process Flow Diagram
    • Determine the start and stop points to your flow of process steps . The stop point is typically near the customer.
    • Walk through the flow, writing down the process steps as they exist now (Rule of thumb: Pretend your are the part). Make sure you use a verb to describe the process step.
      • You can be very general or very specific.
        • General: “Machine Part”
        • Specific: “Turn part, grind outside diameter, and deburr part”
    • At a minimum, record the process steps, decision points, and transportation methods
    • Once you have roughly mapped out the process, make it more formal by adding symbols.
    • Once finished, sign and date the flow diagram with a revision level.
  • What Can Be Included in a Simple Process Flow Diagram
    • Transportation methods
    • Start and Stop points
    • Decision points
    • Inventory/Storage points
    • How many operators at each process step
    • Process parameters for each step: Cycle time, throughput time, scrap rate, etc.
    • Responsibilities for each step
  • Process Flow Diagram Symbols Activity (Process Step) Decision Point Start/Stop External Transportation Inventory/Storage Push Material Data Box c/t c/o u/t FTQ Data box for recording cycle time, first time quality and other process operating characteristics
  • Exercise for Process Map
    • Take a critical operation in your work place and map it with a simple process flow diagram.
  • A Deployment Flow Chart (Swim Lane)
    • Here a "department" or "agency" dimension is added horizontally along the top of the chart. You may use individuals, groups, departments, functions, etc. - whatever kinds of 'units' play major roles in the process.
    • Draw vertical lines to separate the functional boundaries.
    • When the flow moves from one function to another, a horizontal line denotes this.
    • Draw the sequence of activities from top to bottom.
    • Use the task and decision-making symbols as before and always connect symbols with arrows indicating the direction of flow.
  • Exercise for Deployment Chart
    • Convert your simple flow diagram into a deployment chart
  • SIPOC
    • Suppliers: The entities that provide whatever is worked on in the process (information, forms, material). The supplier may be an outside vendor or another division or a coworker (as an internal supplier).
    • Input: The information or material provided by the supplier and used by the process..
    • Process: The steps used to convert inputs into outputs. (some steps are value added and some are not value added)
    • Output: The product, service or information being sent to the customer. This is what the customer pays for. He/she wants output:
      • With good quality
      • Delivered on time
      • At a competitive price
    • Customers: The next step in the process, or the final (external) customers.
  • How To Create a SIPOC Diagram
    • Create an area that will allow the team to post additions to the SIPOC diagram. This could be:
      • A transparency (shown with an overhead projector) made of the SIPOC template
      • Flip charts with headings (S-I-P-O-C) written on each
      • Headings written on post-it notes posted to a wall.
    • Begin with the process. Map it in four to five general steps.
    • Identify the outputs of this process.
    • Identify the customers that will receive the outputs of this process.
      • You can add a sixth column and list the customer’s requirements (CR) such as a blueprint number, specification number, quality goals, and delivery goals.
    • Identify the inputs required for the process to function properly.
    • Identify the suppliers of the inputs that are required by the process.

  • SIPOC Examples
  • SIPOC Diagram Exercise
    • Take your simple process flow diagram and use it to build a SIPOC diagram.
  • Other Mapping Techniques
    • Value Stream Mapping: Every lean event or initiative should start with a value stream map (VSM). In addition to showing the sequence of process steps, the map helps identify areas of process waste.
