This research aims to discover if Lean Six Sigma can add value on an organization that specializes in Mission Critical Facility construction projects. The type of facility that will concern us the most is the Data Center. The company we will study is called PULSAR SA. This name is fictional because the original company wished to keep its anonymity. After carefully reviewing the data we have gathered we selectively chose three Lean Six Sigma tools for this case. This selection is objective and varies according to the type of the organization and the nature of the issues to be resolved.
