How does a scrum work?

Question

Could you explain in as much detail as possible how a scrum works? i.e. the role of every player involved and what happens

Answer 1

There are 8 players in the scrum, essentially in three rows. The front row consists of the loose head prop, the hooker, and the tight head prop. The two props support the hooker and provide the push against the opposing scrum. The hookers job is to "hook" the ball back on an attacking scrum or steal the ball away on a defending scrum. The second row are the locks. These two players put their heads between the legs of the prop and the hooker and provide most of the push in the scrum. The back row consists of the two flankers and the eight man. The flankers are on the outside of the second row players. Their job is to make sure the ball stays within the scrum and be the first out of the scrum to make plays or tackles. The eight man is behind the second row players and has the same job as the flankers.

So in a "perfect" scrum, the scrum half will roll the ball into the scrum and the hooker will hook it back. The scrum will drive over the ball, and the second row players will step over the ball. The Eight man will keep the ball in the scrum until the scrum half is ready to take the ball and run a play.

However, the opposing scrum can steal the ball if the hooker can hook it to his scrum or they can drive over and steal the ball. Hope this helps. It will make more sense if you look up some video.

Answer 2

Scrum framework was originally envisioned and developed to be flexible in nature and possess the capability to adapt itself to the changing development requirements. If during the course of the development, if the stakeholders change their minds regarding the project, or desire to change their project related requirements, the situation can be handled in a more beneficial and cost effective way using scrum methodology. Scrum is synonymous with Agile. Scrum, or Agile framework offers an opportunity to make amendments in the project definition while the project is underway. This is a unique feature, since most development methodologies such as the waterfall, which supports a linear structure for development, have no answer or solutions which can effectively cater to changing project requirements. Moreover, a project can be modified to include additional or new functionality when it is underway. If the client decides that a project should offer some features which have not been thought of before, or thought about during the project planning stage, scrum can incorporate these requirements within the development plan. On the other hand, if the project owner feels that some of the features offered by the product may fail to score in the market when the product is launched, those specific features can be easily removed and replace by new ones. Scrum focuses upon development at a micro level. The development activity is implemented and controlled at a very low level, where it is possible to interact with the basic components which constitute to form the project as a whole. It is always much easier to deal with smaller things and change them when they are small in size, rather than wait for them to attain a big size when managing them becomes very complex, and impossible.

Answer 3

Baltimore has it pretty much right. I would only add another twist to be aware of -- if the defence can wheel the scrum 90%, so that the tunnel becomes perpendicular to the try line, then the ref blows the scrum down,and resets it, but with the put-in being transfered to the team that had been defending -- effectively a turn-over.
