Scrum is all about common sense called ScrumSense

You need to deliver working product (value) faster and earlier as per the customer needs. Can you do so by doing the following steps in a sequence: define --> design --> develop --> test -->deploy? Just by applying common sense, you can find out most of these steps can be parallel. If you apply more common sense then you will realize that many of the steps can be automated to yield even better results. Well, someone correctly said  that common sense is not so common, hence, waterfall model survived too long.



Two common men's (Ken Schwaber & Jeff Sutherland) common sense was tingling, hence, they consolidated bunch of common sense practices and named it Scrum. Then a bunch of folks with common sense joined them to spread common sense through out the world as  ScrumAlliance.  Interestingly, you can pay to get trained and certified for learning, adopting, implementing and spreading this common sense (ScrumSense). As a result, ScrumSense is much more common these days. Welcome to the world of ScurmSense. Don't just learn to use it but spread it every day. Let ScrumSense prevail!
