Prerequisites
As Unidades Curriculares (UCs,) de Gestão da Qualidade e Planeamento e Controlo da Qualidade proporcionam aos Estudantes contacto com um conjunto de conhecimentos sobre ferramentas da qualidade e técnicas estatísticas que se revelam da maior utilidade para os Estudantes que pretendam frequentar a UC de Seis Sigma.
Adicionalmente, Metrologia e Sistemas de Medição, Qualidade e Operações em Serviços, Técnicas Avançadas da Qualidade, Fiabilidade e Lean Management são UCs que podem revelar bastante úteis aos Estudantes que que pretendam frequentar a UC de Seis Sigma, nomeadamente na realização de Trabalho Prático (Projeto Seis Sigma).

Teaching method
Theoretical and practical lectures, combining an expository approach of theoretical contents with a practical approach, by performing practical exercises and analysing/discussing research work on Six Sigma projects (e.g., master dissertations and journal articles).
Evaluation method
The final grade consists of an assessment of a group project and a written test (40% final grade).
Group project (maximum five students) (60% final grade): it is carried out throughout the semester and consists of several stages in which the information required to perform each stage is provided by the teacher in a phased manner, thus allowing, the understanding of theoretical concepts with the practical application of the six sigma methodology. Obtaining frequency in UC requires the development, presentation and discussion of group project. The final evaluation of this component reflects not only the three aspects mentioned above but also the individual performance of each group elements.
The approval in the course requires a minimum grade of 9.5 in each component.
