Sistemas de gestão integrados: desenvolvimento de um modelo para avaliação do nível de maturidade
Tese de doutoramento do Programa Doutoral em Engenharia Industrial e de SistemasIntegração é definida como “o ato ou processo de tornar inteiro” e sistema como “arranjo de
elementos interrelacionados e interatuantes, tais como processos que utilizam vários recursos de
modo a atingir objetivos predefinidos”. As organizações humanas despendem uma grande
quantidade de trabalho a desafiar um dos conceitos mais básicos da física: a entropia. A “ponta do
iceberg” visível desta guerra intestina contra a tendência das organizações para a desordem são
os sistemas de gestão.
Os sistemas de gestão mais reportados a coexistirem num Sistema de Gestão Integrado (SGI) são
o Sistema de Gestão da Qualidade (SGQ), implementado segundo a norma ISO 9001, o Sistema
de Gestão Ambiental (SGA), implementado segundo a norma ISO 14001 e o Sistema de Gestão de
Segurança e Saúde no Trabalho (SGSST), implementado segundo a norma OHSAS 18001. O
objetivo do trabalho realizado foi o de analisar o fenómeno da integração de sistemas de gestão,
identificar áreas de investigação abertas, propor soluções para colmatá-las, nomeadamente
através do desenvolvimento de um modelo que permita avaliar a maturidade de um SGI.
Como ponto de partida, a revisão bibliográfica efetuada procedeu ao levantamento de todas as
questões abordadas pela literatura científica relacionada com a integração de sistemas e com
modelos de maturidade e, a partir da caracterização do estado-da-arte, identificou as áreas para as
quais ainda não há respostas ou onde, apesar de já existirem, as mesmas são de natureza difusa.
Constatou-se que a integração de sistemas de gestão é um fenómeno caracterizado pelo número
elevado de variáveis envolvidas, nomeadamente, a estratégia utilizada, o processo de
implementação, a tipologia de auditorias e o nível de integração atingido, entre outras. A revisão
bibliográfica inicial permitiu também o desenvolvimento de questionários, que se revelou a
principal metodologia de investigação adotada.
O recurso a metodologias alternativas na análise de resultados confirmou a relação existente entre
as motivações iniciais para implementação de um SGI e os benefícios daí resultantes. A
clarificação da posição do SGQ num contexto de integração, identificando as várias posições que
este subsistema pode assumir, contribuiu com informação crítica para a gestão de topo, focando o
sucesso do processo de integração. O contributo final desta tese consubstanciou-se na elaboração de um modelo de maturidade que
permite avaliar a maturidade de um SGI assente em dois componentes: o back office e o front
office. Esta tarefa permitiu que outros contributos fossem também possíveis, nomeadamente, a
realização de uma macro-análise ao fenómeno da integração de sistemas de gestão a nível
mundial, ao desenvolvimento de indicadores macro e à avaliação da sua assertividade por
comparação com outros indicadores baseados em diferentes fontes.
A natureza diversa da pesquisa bibliográfica realizada permitiu também a identificação de
conceitos externos ao processo de integração, mas cuja adoção permite um acréscimo à
maturidade dos SGIs. Tópicos como a avaliação e gestão do ciclo de vida, a macroergonomia, a
sustentabilidade e a responsabilidade social foram identificados como coadjuvantes para uma
integração mais profunda, contribuindo para um SGI com maior maturidade.
O desenvolvimento de indicadores macro para avaliação da dispersão a nível mundial dos SGIs
permitiu concluir que a sua evolução, durante o período temporal de 1999 a 2011, se traduz num
acréscimo acentuado em todas as macro regiões consideradas. A nível nacional, as empresas que
desenvolveram um SGI situam-se, principalmente, nas regiões Norte, Centro e de Lisboa sendo a
tipologia de SGI mais adotada aquela na qual estão integrados os SGQ, SGA e SGSST.
Os resultados do questionário dirigido aos peritos permitiram distinguir empresas com um alto
nível de integração. A utilização das mesmas ferramentas e metodologias organizacionais em cada
subsistema e o alinhamento de objetivos, bem como o facto de a empresa monitorizar os seus
processos com base em indicadores integrados são evidências de um nível de integração máximo.
No modelo de maturidade desenvolvido é possível constatar que três variáveis dão um contributo
superior às restantes para a variável latente “Maturidade do SGI”. São elas a visão integrada
revelada pela gestão de topo, a classificação do nível de integração atingido e a tipologia de
auditorias realizadas.Integration is defined as “the act or process of making whole or entire” and System defined as “an
interrelated elements array, such as processes, using several resources to achieve set goals”.
Human organizations take a lot of work in order to defy basic physics laws namely entropy. The
visible “iceberg peak” of this subtle war against organizations disorder trend are the management
systems.
The most commonly reported subsystems combined into a single Integrated Management System
(IMS) are the Quality Management System (QMS) implemented according ISO 9001 standard, the
Environmental Management System (EMS) implemented according ISO 14001 standard and the
Occupational Health and Safety Management System (OHSMS) implemented according OHSAS
18001 standard. The main objective of this thesis is to analyse all management systems
integration phenomenon, to identify open research paths and to present solutions, namely, through
a model development aiming at IMS maturity assessment.
The thorough literature review undertaken, focused on open questions identification related to IMS
and maturity models, depicted some unanswered questions, some with diffuse answers and some
questions never made. The initial literature review allowed the development of the surveys focused
on the organizations and on the selected academic and industry experts being this methodology
the thesis corner stone. A back office and front office based maturity model development assessing IMS was the ultimate
contribution from this thesis. This contribution, on its own, and sustained on multi-methodological
tasks, allowed some other contributions, namely, the macro analysis of the management systems
integration phenomenon worldwide, macro-indicators development and their evaluation by
comparison with other indicators based on different sources.
Some alternative methodologies adopted on results analysis contributed on some issues raised by
several authors, namely, by confirming the relation between IMS implementation initial motivation
and the benefits collected afterwards. Additionally, the QMS reposition after the integration process
was assessed and three main strategies were identified. This identification enables top management with crucial information aiming at an integration successful process. Literature review
allowed also external concepts identification that relates to IMS maturity. Topics like life cycle
management and assessment, macroergonomics, sustainability and social accountability should be
taken into account, enabling a deeper integration, and a more mature IMS.
The results promoted several critical success factors identification that should be considered when
integrating management subsystems. Some characteristics intrinsically related to high integration
level organizations and low integration level organizations were identified.
It was possible to conclude that management systems integration phenomenon is characterized by
the high number of variables involved. The adopted strategy, the implementation process, the audit
typology, the IMS typology, the motivation, the benefits, the obstacles and the achieved integration
level are among those variables.
Through macro-indicators development aiming the IMS dispersion worldwide analysis one may
conclude that they evolved positively and increased in number during the time period between
1999 and 2011. At a national level, it is possible to conclude that the organizations that developed
an IMS are mostly located at the North, Centre and Lisbon regions. The integrated QMS, EMS and
OHSMS is the IMS typology mostly adopted. The results collected from the survey among academic and industry experts allowed the
identification of high integration level organizations. According to these results, the development
and adoption of the same tools and methodologies by each subsystem and objectives alignment,
processes monitoring based in integrated indicators are evidences of a maximum integration level.
The maturity model final version allows the conclusion that three variables contribute the mostly to
the “IMS Maturity” latent variable. Those variables are the integrated vision by top management,
the integration level classification and the audit typology. External concepts and the eight
excellence management pillars relate also to the IMS maturity
Quality scoreboard: a proposal
Purpose: The assessment of “macroquality” or the assessment of the degree to which the quality
practices are implemented in a country or a region should not be only based on “tangible” indicators such
as the number of certified companies according to the ISO 9001 or ISO 14001 standards, or others. By
adopting only these two indicators (or similar ones) a large amount of companies, those ones that are not
certified, are not considered when assessing the “macroquality”. Less tangible features, such as the
number of persons trained in quality management or the number of members of quality management
associations among other features, contribute themselves and seem appropriate to assess the level of
“macroquality”. This paper intends to report a “macroquality” index that is composed by tangible and less
tangible features, concerning the quality practices implementation concept- The Quality Scoreboard.
Design/methodology/approach: An expert’s panel was conducted with the aim of evaluating a set of
several indicators that could be used to assess and to monitor the “macroquality” level of a country. Nine
tangible indicators were proposed and been analysed by the experts’ panel according to an importance
scale (1 to 5). Additionally, the experts were encouraged to propose other indicators that could reflect the
quality state-of-the-art of a country or region.
Findings: Experts find that tangible indicators are not enough to express the level of “macroquality”.
According to the results, less tangible features should be considered too. A total of 43 indicators were
suggested by the experts. Among them, the following suggested indicators should be highlighted: the
number of persons trained in quality management, the number of members of quality management
associations, the number of quality related courses at the universities and the number of certified
auditors. Based on the survey results a Quality Scoreboard was developed.
Originality/value: As far as we were able to find out this is the first attempt to develop a Quality
Scoreboard, as it had been already done to innovation. This new approach allows one to characterize the
quality state-of-the-art of a region, based on a set of potential “quality indicators”. Furthermore, the results
provide an additional important contribution to the worldwide study of quality approaches diffusion and
evolution
Maturity models: a useful solution to assess current OHS management system
Occupational health and safety management systems (OHSMS) are implemented worldwide and by
an increasing number of companies. Usually this management sub-system is not the first one to be
implemented and is seldom the only management sub-system implemented by a company. Therefore,
the OHSMS performance is most appropriately assessed if one considers it within an integrated
management system (IMS) and, usually co-existing, with a quality management sub-system (QMS) and/
or an environmental management sub-system (EMS). Furthermore, OHSMS actions are often, if not
always, constrained by quality and/or environmental requirements. The dynamics of complex systems,
such as IMS, have been targeted by numerous researchers in different scientific domains. All of them
pointed out that these systems are characterised by a non-linear behaviour and a large amount of
variables often related to each other. Maturity models have been adopted to minimise our complexity
perception over a truly complex phenomenon. In this sense, maturity models are tools based on a
non-deterministic methodology, which enable the assessment by the identification of the most relevant
variables that influence their outputs. Ideally, besides this identification, a maturity model should provide
information concerning the qualitative and quantitative relationships between variables and how they
affect the latent variable, i.e. the maturity level of the maturation object.
Regarding OHSMS (maturation object) assessment, one may assess it based solely on OHSMS
indicators, but further improvement actions should also rely on the contributions of other implemented
management sub-systems, thereby reflecting an integrated context. This fact reformulates the purpose
of OHSMS within a company and demands a systemic vision by the OHSMS manager. Some other issues
should be considered, too, such as the implementation of integrated indicators, audits and procedures,
and the harmonisation through adoption of a common ‘language’ between the sub-systems. Some
features concerning the intrinsic philosophy from each sub-system may be benchmarked for the
remaining sub-systems, as the systematic risk approach that characterises the OHSMS. It is intended in
this paper to report several maturity-model characteristics that enable such models to act as suitable
tools for assessing management systems’ maturity and, specifically, that of the OHSMS. Additionally,
it is also intended to synthetise all the main features found in the literature review performed, namely:
which are the key questions to consider prior to model definition; which limitations should be expected;
the definition of the main relevant concepts, such as maturity, capability, maturation and maturation
object; and the classification of existing maturity models. Finally, a maturity model enabling integrated
management systems assessment will be presented, as well the main advantages of adopting this
model, concerning OHSMS features. This model, based on front-office and back-office components,
considers the key process agents (KPAs) identified through a systematic literature review, and by the
conduct of several case studies of companies, as well as the qualitative and quantitative relationships
between these variables and their contribution to the latent variable (IMS maturity level). Ultimately this model translates the OHS management sub-systems’ current reality – namely, the fact that their
implementation and daily management are not independent from other management sub-systems and
their requirements
Latest developments aiming an integrated management systems tool focusing maturity assessment
Publicado em "Proceedings of the 2012 IEEE IEEM"Integrated management systems (IMS)
widespread among companies due to the release, by
international entities, of management sub-systems
implementation standards. The integration level
achieved by the IMS varies from company to
company. Rating the integration level is crucial
information. Maturity models have been implemented
in several business, product development and in
management sub-systems context in order to guide the
company to an ultimate excellence level. An IMS
maturity model development is, currently, aimed by
researchers and a real need in companies. It is
intended in this paper to report the efforts that are
being made and the methodologies that are being
followed to develop such a model. Additionally, it is
also intended to present a preliminary model version

An integration of QFD and Fuzzy-AHP approach in hospital services, case study: a hospital in Iran
Purpose This paper shows a development of an integrated model to identify the customer needs and select the best solution to optimize the quality of healthcare systems, namely at hospitals. Design/methodology/approach After determining the patient's requirements by data gathering from experts and patients, a questionnaire was prepared to implement the Fuzzy Analytic Hierarchy Process (FAHP) method. Afterward, the requirement's weight has determined by the patients. Finally, the most important technical requirements were achieved applying the 3-phases Quality Function Deployment (QFD) model. Findings The results show that by adapting the FAHP on ideas of the patients and hospital's experts to determine the weights of patients' requirements, led to have more flotation in FAHP questionnaires in the hospital services. In this domain, adopting the decision-making tools help more precise ranking of patients' requirements. Originality/value Since high-quality urgent services are vital to the protection of human life, it is significant to precisely rank the patient’s requirements by novel methodologies. By the implementation of an integrated model using FAHP and QFD, we were able to show the improvement of the quality of an hospital in Iran. After precisely ranking the patient requirements, "increasing human resource" and "establishing requirements and instructions in initial measures and reducing medication errors", are obtained as the most important technical requirements.This work was supported by National Funds through FCT (Portuguese Foundation for Science and Technology), and the first author acknowledges the grant PD/BDE/143092/2018 provided by FCT.

Selection of Saccharomyces cerevisiae strains for efficient very high gravity bio-ethanol fermentation processes
An optimized very high gravity (VHG)
glucose medium supplemented with low cost nutrient
sources was used to evaluate bio-ethanol production
by 11 Saccharomyces cerevisiae strains. The industrial
strains PE-2 and CA1185 exhibited the best
overall fermentation performance, producing an ethanol
titre of 19.2% (v/v) corresponding to a batch
productivity of 2.5 g l-1 h-1, while the best laboratory
strain (CEN.PK 113-7D) produced 17.5% (v/v)
ethanol with a productivity of 1.7 g l-1 h-1. The
results presented here emphasize the biodiversity
found within S. cerevisiae species and that naturally
adapted strains, such as PE-2 and CA1185, are likely
to play a key role in facilitating the transition from
laboratory technological breakthroughs to industrialscale
