Abstract

Recently, lean six sigma has been applied to the service context. In the literature, there is no strong empirical evidence to clarify how lean six sigma can be applied in sourcing, where there is an extensive use of information technology and communication (ICT) systems. This study presents a methodology to streamline and digitize processes in order to reduce waste. It does that by using an approach indicated as “Lean and Digitize”. Based on the analysis of best practices and on several real implementations, a framework was developed and applied to the sourcing processes. The study found out that the digitization of a process not streamlined can generate problems. A process must be mapped to highlight waste and low quality. The new process should be improved taking also into account that it will be possible to use ICT supports. Once  that is done, the process can be digitized. The new process will digitize only value-added activities recognized by the users and by the organization.

Key words: Lean thinking, six sigma, sourcing, digitization.
