Oi was the first and only company in Brazil to receive the international accreditation for its 6 Sigma Program. This accreditation comes from CSSC – Council for Six Sigma Certification, an entity based in the US, the most credible six sigma accreditor globally, operating in over 165 countries.

Oi developed a hybrid model that combines 6 Sigma and Agile methodologies to help achieve results more assertively with its pioneering spirit. Since 2011, the program has already earned more than R$1,4 billion in return for Oi and today has more than 2,500 certified belts.
