Ohh, very interesting topic, I tihnk there's a lot to say about that!
Yesterday I watched a video at the uni where Peter Druker talked about many topics, and one of them was the importance of the productivity of knowledge in the 21st century. Globalization implies a changing environment, where an event that happens 5000km from where you live may have a huge impact on the economy, and even more important, the society you belong to. Last century a worker's most tool was his hands, and productivity studies in industries focused on that. Gilbreth, for example, wanted to reduce the number of movements a worker did with his hands to make him more productive.
But now Peter Druker talks about "knowledge workers", so I think our first aim should be to increase our knowledge as much as we can. Knowledge is what makes us different form others, and it's an enterprise's most important competitive advantage. And the second point is to make that knowledge productive, which involves being able to adapt it to the needs of a world where change is often unpredictable. But I think it's crucial to get that knowledge, without it you certainly can't be a productive member in a global society.
Lol, I think I only focused on management aspects (I find it so interesting), but I hope it's useful and you can get some ideas for your essay. Good Luck! :thumb:
