"É bom, mas não é eficaz."

Translation: It is good, but is not effective.

[Bonnie_B]

There are two translation options given; both efficient and effective, but these words have a different meaning. So what would be effective and what efficient?

[Paulenrique]

in Portuguese "eficiente" and "eficaz" are user the same way. Efetivo means for a long period (Ele é nosso novo funcionário efetivo)
