Abstract(s)Maturity models enabling the assessment of integrated management systems (IMS) are crucial in order to provide a comparison between IMS from different companies. This paper intends to report the efforts made and the methodologies followed to develop an IMS maturity assessment model. Additionally, the paper aims at presenting such model, illustrate its usefulness, and demonstrate how companies may implement it as an organizational guide focusing an ultimate excellence level. Two surveys have been developed. An online survey with 30 questions/statements was held focusing Portuguese companies with more than one certified management subsystem according to the following standards: ISO 9001, ISO 14001 and OHSAS 18001/NP 4397. The survey was supported on Likert type scales, with categorical and multiple option answers/statements. A pre-test was performed in three companies in order to validate the survey. A second survey was developed and submitted to the appreciation of an experts group to assess in what extent each parameter could reflect the management system integration level. The maturity model reported in this paper provides companies with a guiding path in order to achieve an ultimate excellence level. The final model version is sustained on two components, namely, a back office component, describing the statistical relationships between variables, and a front office Capability Maturity Model integrated (CMMi) based component, enabling companies to interact with the model. The back office component was developed through linear and multiple regression models and by statistical significant variables identification affecting an “IMS maturity level” latent variable. Additionally, Pearson correlation was assessed among those variables not statistically related to the latent variable. Front office component has five maturity levels and a “zero level” acting as a pre-requirement and enabling, or not, the access to the maturity assessment model. To access at higher maturity levels the IMS should comply with excellence management requirements, external factors requirements and key process agents’ (KPAs) requirements.
