Sipoc
The document discusses SIPOC diagrams, which are visual representations of high-level processes that include suppliers, inputs, the process, outputs, and customers. SIPOC diagrams help teams agree on project boundaries and scope. They also help ensure inputs match upstream processes and outputs match downstream processes. The document provides an example of creating a SIPOC diagram for the process of mowing a lawn. It walks through identifying the suppliers, inputs, process steps, outputs, and customers. The document concludes with discussing how SIPOCs can be used and providing an in-class exercise to create a SIPOC for a project.

Editor's Notes
- #2 Class Preparation materials: Butcher paper to post on the walls. One large piece for each 5-8 person team expected in the class. Large = 3’ X 2’. Post these blank sheets on the wall before class. 2. Sticky notes, at least one pad for each team. 3. Sharpie pens for each team. 4. Tape to attach charts to the walls. 5. Flipchart for instructor, with pens. Chalkboard or whiteboard will work if a flipchart is not available.
- #4 Class Agenda Welcome and Introductions (spend a few minutes to get to know the class & their needs) On a flipchart, capture what each student would like to get out of the class. Post the flipchart on the wall. Refer back to it at the end of class to make sure all questions/ideas have been addressed. SIPOC Defined (2 slides) How can SIPOC be used in your organization? (2 slide) How It Works (6 slides) An Example (6 slides) In-class Exercise (6 slides) Summary (1 slide)
- #5 SIPOC is a simple acronym. The SIPOC Diagram is the tool that holds the real power to convey meaning and understanding.
- #6 A SIPOC Diagram is a communication tool. It visually documents a process. A high-level process map shows only the major steps of a process. Detailed steps come later, in the Measure phase if you are using DMAIC. It provides a fact-based process description as a basis for understanding “current state” It is a simple diagram for identifying the basic elements of a process (boundaries, suppliers, inputs, process steps, outputs, and customers) SIPOC is a good tool for translating customer requirements into input & output requirements and identifying related Key Process Input & Output Variables (KPIVs & KPOVs) SIPOC establishes project scope and should be referred back to in later project phases to ensure adherence to scope & eliminate scope creep. Be very clear about where the process starts and where the process ends. This should align with and help define your project scope.
- #7 SIPOC can be used to define the scope and boundaries of your project. It helps communicate inside and outside an organization. If a project scope has already been defined, SIPOC can validate the accuracy of the scope. If you are following the DMAIC (Define, Measure, Analyze, Improve, and Control) problem-solving methodology, SIPOC is introduced in the Define phase of the project
- #8 Break into small groups of 3-4 people. Take 5-8 minutes and brainstorm how, when, and where SIPOC can be used in your organization. Have each group briefly report back on their discussion. SIPOC is a precursor to creating more detailed process maps and value-stream maps
- #9 Key point on forming a team to develop a SIPOC Diagram: Involve a cross-section of those who work with the process to create the diagram. No single person will have all the process knowledge you need.
- #10 To construct a SIPOC diagram, begin with a high level process map, usually consisting of four to five steps. Then list outputs of the process, followed by the customers who receive the outputs. Then turn your attention to the front end of the SIPOC, with a listing of the inputs to the process and their suppliers. (ASQ Certification Board Puts Quality Tools to Work. Scott A Laman, Elizabeth Burns, Kathy L Lynn. Quality Progress. Milwaukee: Mar 2007. Vol. 40, Iss. 3; pg. 54, 9 pgs) Reminder: Be very clear about where the process starts and where the process ends. This should align with and help define your project scope. Keep the process map to the highest level. Don’t be tempted to dive too deeply into process steps at this point. Keep it to 4-5 steps. The process you choose for your project may be a subset of a larger process or a standalone process.
- #11 Start by brainstorming with the team about outputs. Outputs can also include requirements. For example, each product produced may have a tolerance level to meet quality requirements. If you have a lot of outputs, focus on the critical few. List the outputs on the diagram.
- #12 Getting started the right way is critical - properly identifying suppliers and customers is necessary, using SIPOC can help identify the players Next, identify those people or processes that receive the output. Take special note of any downstream processes, do the outputs of this process match the inputs of the downstream process? List the customers on the diagram.
- #13 Now we turn our attention to the process inputs. Inputs can also include requirements. For example, raw materials may have a purity level to meet quality requirements. If you have a lot of inputs, focus on the critical few. List the inputs on the diagram.
- #14 Finally, identify the people, systems, or upstream processes that supply the inputs. Take special note of any upstream process, do the inputs of this process match the outputs of the upstream process? List the suppliers on the diagram.
- #15 Mowing the lawn = Prepare lawn for mowing -> Mow lawn -> Trim lawn -> Clean-up & removal Other examples that could be used as illustrations: Delivering newspapers = Prepare papers for delivery -> Deliver papers -> Collect payments Taking Wedding photos = Prepare location -> Take photographs -> Develop photographs -> Deliver photographs Changing motor oil & parts = Receive incoming vehicles -> Drain oil & remove old filter -> Install new filter & refill oil -> Complete transaction & return vehicle
- #16 This is an animated slide - 4 clicks to display the process Reminder: Be very clear about where the process starts and where the process ends. This should align with and help define your project scope. Keep the process map to the highest level. Don’t be tempted to dive too deeply into process steps at this point. Keep it to 4-5 steps. Note that selecting a lawn or negotiating with a homeowner are outside the scope of our example process.
- #17 This is an animated slide - 5 clicks to dissolve the arrow an display the 4 outputs Click through the outputs, discussing briefly. Point out the possible output requirements, such as the lawn must be 3 inches long or grass clippings must be put in a recyclable bag.
- #18 This is an animated slide - 3 clicks to dissolve the arrow and display the 2 customers Click through the customers, discussing briefly.
- #19 This is an animated slide - 7 clicks to dissolve the arrow and display the inputs Click through the inputs, discussing briefly. Point out the possible input requirements, such as the lawn must be 4 inches long or the gasoline must be unleaded and mixed with oil.
- #20 This is an animated slide - 4 clicks to dissolve arrow and display the suppliers Click through the suppliers, discussing briefly.
- #21 Let’s create a SIPOC for an in-flight or planned project in your organization. Break the group into teams of 5-8 people. Pass out Sharpies and Sticky Notes to each team. Assign each team one of the blank pieces of butcher paper, which have previously been taped to the walls. Brainstorm a project that you would like to use for this exercise. Remember, the process you choose can be a subset of a larger process. Take 4-5 minutes.
- #22 Begin with your high-level process map. On the large butcher paper on the walls, draw a SIPOC diagram skeleton. Using the sticky notes, write each step on a different sticky note and place the process steps on the diagram. Draw in the arrows on the paper or on sticky notes. Be very clear about where the process starts and where the process ends. This should align with your project scope. Remember to keep with high-level process steps. Detailed process steps come later.
- #23 As a team, brainstorm all of the outputs from the process. Write each output on a sticky note and place them on the output column on the diagram. Brainstorm key output requirements that need to be accounted for. Place each one on a sticky note and align the key requirements to the corresponding output. Think of downstream processes, have you identified all of the inputs for those processes? If you have a lot of outputs, focus on the critical few.
- #24 As a team, brainstorm all of the customers of the process. Write each customer on sticky note and place them on the Customer column on the diagram. Remember the downstream processes.
- #25 As a team, brainstorm all of the inputs into the process. Write each input on a sticky note and place them on the input column on the diagram. Brainstorm key input requirements that need to be accounted for. Place each one on a sticky note and align the key requirements to the corresponding input. Think of upstream processes, have you identified all of the outputs for those processes? If you have a lot of inputs, focus on the critical few.
- #26 As a team, brainstorm all of the suppliers of the process. Write each supplier on sticky note and place them on the Supplier column on the diagram. Remember the upstream processes.
