Kindly help me in understanding all the below points WITH SCENARIO BASED;
1)Scrum makes clear the relative efficacy of your product management and development practices so that you can improve. (Page 3)
2)Specific tactics for using the Scrum framework vary and are described elsewhere. (Page 3)
3) Empiricism asserts that knowledge comes from experience and making decisions based on what is known. Scrum employs an iterative, incremental approach to optimize predictability and control risk.
