This research is based on two problematic situations: the poor performance of the Help Desk process in a public institution, and the absence of a methodology to improve processes appropriate to Peruvian reality and in particular to a public institution.

Therefore, the objective of the research is to improve the Help Desk in a public institution, through a disruptive strategy using a new BPM-Six Sigma-Kaisen integrative methodology supported by ICT.
