Each operating unit, even belonging to the same company, has cultural factors that are quite different from each other. Some High Reliability Organizations (HRO) need to carry out several event investigations, which is often conflicting with daily demands. The problem identified is that the quality of the investigation is affected due to behavioral factors of engagement of the leaders involved and insufficient data collection, which can interfere with the results of the investigation. The proposed methodology was the creation of a quantitative assessment of the engagement of all those involved and the phases of the investigation, aiming to draw a profile and obtain an assessment of each investigation and, consequently, to draw a pattern of the different operational units of the company. The contribution of this work aims to make a correlation between the investigated events, their recurrences, and how the engagement considered adequate can generate resilience and impact the results of the investigations. This article is the result of a study in one of the largest industries in the oil and gas sector in Brazil, which works in the bottling and distribution of LPG nationwide. This work has more than 100 investigations that took place from north to south in Brazil in a period of 2 years, in a wide geographic and cultural distribution of 16 different Brazilian States.
