ABSTRACT
SIPOC is a process improvement tool that provides a key summary of the inputs and outputs of one or more processes in tabular form. The acronym SIPOC denotes suppliers, inputs, process, outputs and customers, which represent the columns of the table. It was applied in the field of total quality management in the 1980s and widely used in Six Sigma, Lean manufacturing, and other business process improvement strategies. SIPOC is a vital tool for documenting a business process from start to end. SIPOC is used in the define phase of the define-measure-analyse-improve-control (DMAIC) process (Adams et al. 2004).
