Construction Quality Planning Guide, Draft for Consultation, Published by the Construction Innovation Hub in May 2020, describes Supplier, Inputs, Process, Outputs and Customers (SIPOC) as: ‘A tool from six sigma that provides a tabular summary of the inputs to outputs of one or more processes, known as a SIPOC diagram. Some organisations refer to it as COPIS in order to put the emphasis on customer requirements.’
