In last few days I have compiled some information on SCRUM in separate articles. Here is the consolidation of all the links:
Scrum has been successfully used for projects with 500+ team members lots of time. As SCRUM can only last for 15 minutes and some other similar rules hence in order to scale the SCRUM for bigger team we can use SCRUM OF SCRUMS. Based on the type of work the scrum team is constituted for every 7 to 10 team members having a Scrum master and the Product Owner. After the first lever team SCRUMS we have SCRUM of SCRUMS and there could also be more level of SCRUM OF SCRUMS.
I have listed all these and also linked them to wiki as it has one of the very good definitions and details about every agile methodology.
Once I am done with the Scrum series I will touch the other ones. Hope this helps!

The product backlog is a document that contains the list of all desired work on the project. All these entries have an overall description, priority based on business value and rough estimates specified. This document is owned by the Product Owner and he/she sets the business value for each item. While the team is responsible for updating the development estimates in the document. This document is re-prioritized at the start of each and every sprint.
Sprint Backlog is a team document that is used to plan how the features will be implemented. In this document the team breaks the features into tasks. Normally these tasks are four to sixteen hours of work. If the task has an associated effort of more than 16 hrs it is broken down into a small task. The tasks are never assigned, the team member voluntarily choose the tasks as per the priority and their skills. The Sprint Backlog is owned by the team. The overall outcome of this document can be visualized as a TO DO arranged according to the business value.
The Burn Down chart is used to display the pending work in the sprint backlog. The burn down chart provides the visual representation of the overall progress of the Sprint. This is updated daily and is visible to the world.

Scrum has 3 type of roles
A Product Owner compiles all the changes planned for the product and prioritizes the possible functionalities. - “Scrum in five minutes” by SOFTHOUSE

- Product Owner is
Characteristics of Scrum
- Scrum is one of the
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.
