M4E #107: IPO and the 4Ms
We have talked about Process Operation Management back in M4E #10 and M4E #61 but we have not introduced two basic concepts: IPO (Input-Process-Output) and the 4Ms. This video from POM ETH Zurich will introduce them really well!

Inputs are the resources that a system needs to function — these can include raw materials, information, energy, human effort, or capital. The Process refers to the series of steps or transformations that occur to add value to those inputs — this is where the work happens. Finally, Outputs are the results or deliverables produced by the process, such as finished products, services, or information passed on to the next stage or customer.
SIPOC is a high-level process mapping tool used in Six Sigma and process improvement methodologies to identify and summarize the key elements of a process. The acronym stands for Suppliers, Inputs, Process, Outputs, and Customers. It provides a structured overview of a process by outlining who supplies the inputs, what those inputs are, the major steps of the process, the resulting outputs, and who receives those outputs. SIPOC helps teams understand a process from end to end, define its boundaries, and align stakeholders before diving into detailed analysis or improvements. We’ll check it out in a future video.
This may seem quite basec but by clearly identifying inputs, processes, and outputs, IPO helps teams document and communicate how a system works — especially useful in standard operating procedures (SOPs) and training. Check M4E #26 for SOPs.
