Aprender a utilizar estes softwares não é tão difícil (pelo menos o básico), porém é preciso entender que estes softwares são uma ferramenta de planejamento, não são O Planejamento.

Posted by Armando Brito Mendes | Filed under materiais para profissionais, software
Duplicate values aren’t wrong or bad, but they can be distracting. You probably won’t want to delete them, but you might just want to hide them. For example, the simple sheet below repeats date values in column A. In a reporting scenario, those duplicate dates might be annoying.

Like a dictionary describes words you don’t know in terms you do, Dictionary of Numbers puts quantities you’re unfamiliar with in terms you can understand. Because “8 million people” means nothing, but “population of New York City” means everything.
