A complete SIPOC design guide help create SIPOC diagrams with pre-made templates. Why to use SIPOC, How to Use SIPOC.

Why to Use SIPOC Diagrams?

When you want to start some process management or improvement activity, it's crucial to get a clear overview of the top level stages of the process. SIPOC helps provide a natural but structured way to discuss a process and get consensus on what it involves before drawing process maps. It helps understand and communicate the Inputs, Outputs, Customers and Suppliers of the overall process, especially when you are not clear about the following questions:

  1. Who supplies inputs to the process?
  2. What are the activities involved for the process to transform inputs to outputs?
  3. What're the key inputs needed for expected outputs?
  4. Who're the true customers of the process?
  5. What specifications are placed on the inputs?
  6. What're expected outputs of the process?

When to use a SIPOC Diagram?

Once the process management or improvement activity is underway, you should consider using SIPOC since it's important to get a high-level understanding of the process's scope first. When starting a new process or business, a SIPOC diagram is essential for giving people a high-level overview. For existing business, it helps reacquaint people whose familiarity with a process has faded or become out-of-date due to process changes.


Basic Steps for Creating a SIPOC Diagram

Step 1: Conduct an Overview

SIPOC is best accomplished in team work and brainstorming sessions. To conduct a successful SIPOC session, first provide participants a brief overview of the SIPOC process, purpose, tools/templates, and especially the keys to an effective SIPOC.

Step 2: Use a Template to Build the Framework

The easiest method is applying a ready-made SIPOC template rather than draw it by hand. To best fit your own specific needs, perhaps you need flexible templates that are available to modify. Edraw is an easy-to-use SIPOC maker coming with a variety of SIPOC templates with different designs, all in vector format. You can easily change the box size, arrange the format and customize the SIPOC diagram with only a few clicks. Besides, abundant built-in symbols and illustrations are free in use to enrich your chart. Just take a pre-made template then forward your work.

To apply a ready-made template, please click Diffrent Templates for Diversified SIPOC Design, or discover more templates on the Templates page, Flowchart category, Process section. To design a SIPOC chart on your own, simply open the List and Process library in Edraw, and make a SIPOC diagram instantly from a large collection of pre-made shapes. Or you can use a cross-functional flowchart to represent your SIPOC diagram.

Step 3: Identify SIPOC Components and Complete the Chart

Now identify each of the components for the whole process and fill in your chart.

  1. Process: Usually you start with process step first. It is a high-level process map with no more than 7 steps. It should define the activities of how you convert your inputs to outputs. Make sure the team approves with the representation of the process. Use a Verb + Noun format for the process steps. Such as "Add Source" or "Deliver the Goods".
  2. Outputs: For a process that produces a product, the primary output is obvious to identify. While for service-oriented processes outputs may be less apparent. Outputs of the process don't just include the product or service you are delivering, they can include paperwork, approvals, data, and just about anything else you can think of that results from your process. If you have a lot of outputs, focus on the critical ones.
  3. Customers: These are the recipients of each output of your process. Every output should have at least one customer. Better to match the customers to the outputs.
  4. Inputs: Determine what you need to produce the outputs. Inputs can include materials, people, machines, IT systems, information, or anything else that is necessary for the process to run. Brainstorm and capture the crucial ones under the Inputs column.
  5. Suppliers: Identify who supply you inputs. Document the suppliers of each input under the Suppliers column. It visually depicts which suppliers provide which inputs.
  6. A Diagram Clearly Shows the Basic Steps:

  1. Don't try to do this alone, or you may miss key information as you progress through your project.
  2. Be concise, complete on one sheet of paper, as it's a high-level overview.
  3. An effective SIPOC diagram tool will help you end up with a presentation quality diagram quicker.
