SIPOC diagram is a six sigma tool used to document or map overall business processes.
There are various tools in lean 6σ. One has to know when to use which tools. The lean six sigma methodology combines the lean principles, that is reducing the waste and principles of six sigma (6σ), that is to reduce defects in the services or products and reduce variations in the processes. The project manager is entrusted with the responsibility of choosing the correct project management approach for the project and the organization. There are a lot of Lean 6σ tools such as Kaizen, the 5 why’s, the process capabilities Cp and Cpk, Kanban, the 5 S of the systems, PokeYoke, DPMO, Critical to Quality, Critical to Customer, and SIPOC, etc. These tools achieve the following things,
In this article, we will focus mainly on the SIPOC tool for lean 6σ and how it helps, how to use it, and when to use it.
SIPOC is a health check carried out to find the smooth flow of information and the product line by reviewing the performance measures.
SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers.
When to use SIPOC? The SIPOC is used before the start of the project in the early stages to find the processes and to identify the team members. This is done when implementing the Enterprise Quality Management System (EQMS) when the Service Implementation Manager may ask you to conduct the SIPOC workshop to scope in the processes and to ensure they are rightly configured in the system.
SIPOC Model is because in the product life cycle you need to correctly scope in the suppliers and the accurate process which delivers the right outputs and provides high customer satisfaction
The SIPOC diagram helps define the process measures and the creation of performance measures for the process.
The map shows the primary suppliers and what are the inputs to the processes that can deliver value to the customers in the form of outputs.
From the diagram, we can create the SIPOC map in the following ways. The example discusses the Firewall need for the customer who is having network security issues. This is in turn nothing but the cybersecurity solutions.
6) The requirements consist of the following items,
The SIPOC can be analyzed as follows,
1. The Inputs and Outputs – You need to analyze the Inputs and Outputs to the processes and make the list of them. They are important because you must know what are the customer expectations and the inputs will help the needs of the processes and deliver the right output to the customers.
2. The Suppliers – You need to know at what cost the supplier is providing the materials to you, what is the quality of the raw materials, analyze the cost/benefit ratio of the materials. Think whether the raw materials will suit the customer needs.
3. The processes –Plan the processes by thinking of the customer requirements, they need to be 5 to 8 high-level processes to achieve customer expectations. You can use the COPIS model in which you trace the processes from reverse that is using the customer requirements and working on it backward. COPIS is nothing but the reverse of SIPOC.
4. Customers – Correctly identify what customer wants, that is any issues or problems the customer is facing or there are new enhancements to the previous projects or new products that customer is looking for.
We have discussed in this blog how the SIPOC tool is useful for making the process measures and the process performance measure. There are quite a lot of tools available for the lean 6σ projects.
To know, learn, and to explore more on lean 6σ we recommend you to undergo lean 6σ online training (green belt and black belt) with StarAgile.
