Scrum is a simple agile development methodology through which we can manage complex projects. Scrum allows rapidly and repeated inspection of actual working product (at least once a month or twice) hence provides ability for the project to adapt to rapidly changing market and other complex external factors. The focus of the scrum methodology is to deliver the highest business value of the project in the shortest possible time.
The best part of Scrum for product development is the requirement to demonstrate a real working product every two weeks or once a month helps the management and team to take a calculated decision for the project and product’s future at a regular and a shorter interval. Hence scrum gives the ability to adjust with the competitive market and also to take go-or-no-go decision well in time hence saving lots of resources.
