Why is it important for economic production?

Assuming a company has been created for commercial purposes, then "productive" means that the people within the company are expected to deliver the goods or services for which the company was created. In order to create goods or deliver services individuals must be "productive". As to why it is "important" to be productive, the alternative to productive is non-productive, and the "non" also leads to non-income, non-profit and pretty quickly non-company!
