Team Composition
In a large organization, it is often the case that different roles emerge. In Tayloristic teams, these different roles are grouped together as a number of role-based teams each of which contains members of the same role. In contrast, agile teams use cross-functional teams. Such a team draws together individuals performing all defined roles. Rotations from one role to another are common. It is also possible to have highly specialized experts (for example, security analysts and usability engineers) shared among several teams in an organization.
One advantage to role-based teams is that teams whose work products are independent of each other can work in parallel as long as there is not much knowledge flow among the different functional sub-team. However, in knowledgeintensive software development that demands information flow from different functional sub teams, role-based teams tend to lead to islands of knowledge and difficulty in its sharing among all the teams. As hand-offs between teams usually are based on document flow, the knowledge of one team that is required by the other team must be externalized and documented. Although reviews try to minimize the knowledge loss, externalization and documentation processes cannot guarantee that all knowledge is captured and even if most of it was rigorously captured, there is still no guarantee or way to check its correctness till the project sign-off.
Cross-functional teams should be used to facilitate better knowledge transfer. This is especially the case for agile methods since they are recommended to be used where there is a lot of uncertainty and unknown knowledge about the domain and system requirements, and the technologies to be used are new and unexplored.

Na Linguagem de Programação JavaScript, uma string é imutável. Com base nisso, considere o seguinte trecho de código e assinale a alternativa que apresenta o valor que será exibido no console após a última chamada da função.
var cidade = “Parana”;
cidade.replace(“rana”,“nama”);
console.log(cidade);
Sobre as formas de normalização em um banco de dados relacional, analise as assertivas e assinale a alternativa que aponta a(s) correta(s).
I. Para estar na Primeira Forma Normal (1FN), deve-se criar tabelas separadas para cada grupo de dados relacionados e existir somente uma coluna duplicada em cada tabela.
II. Para estar na Segunda Forma Normal (2FN), deve-se estar na 1FN e eliminar as colunas que não possuem dependência funcional com as chaves primárias.
III. Para estar na Quarta Forma Normal (4FN), deve-se estar na 3FN e não existir dependências multivaloradas.
IV. Para estar na Terceira Forma Normal
(3FN), deve-se estar na 2FN e eliminar as
colunas que não possuem dependência
funcional dentro da chave primária.
