Hi Geeks,

Today i’ll show you a little bit of scrum methology that we can use to define the analyzing and requirement process of our SDLC. 

The pioneer of scrum Jeff Sutherland and Ken Schwarber , they formulated the scrum which is

 “…a lightweight agile project  management method that is enjoying widespread adoption and effective use…”

A view characteristic or the elements of Scrum methodology are :

1. Small, cross-functionality teams work closely together in an open environment to produce incremental releases of a product in 30-day increments, or sprint.·    Teams are self –directed and empowered to meet the objectives of the sprints.
2. Team work is facilitated by a scum master role who does not direct technically activity but eliminates impediments and reinforces the core discipline of scrum.
3. Work is organized via a product backlog,which is reprioritized for each sprint.               Based on the characteristic above then we could move to the next implementation if we choose        the scrum  method   as follow :
4. Cross-Funtionality and collated teams of 8 or fewer team members develop software in sprints.
5. Sprints are iterations of a fixed 30 day duration.Each sprints delivers incremental ,tested functionality of value to the user.
6. Work within a sprint is fixed. Once the scope of a sprint is committed, no additional functionality can be added except by the development team.
7. The Scrum master role  mentor and manage the self organizing and self managing teams that responsible for delivery of successful outcomes at each sprint.
8. All work to be done is carried as Product Backlog, which includes requirements to be delivered, defect workload, as well as infrastructure and design activities.
9. The product Backlog is developed, managed ,and prioritized by the product owner, who is an integral member of the team and who has the primary responsibility of interfacing with external customers.
10. A daily 15 minutes stand up meeting or “Daily scrum” is a primary communicated method.
11. Scrum focuses heavily on time boxing. Sprints, stand-up meetings, release review meetings, and like are all completed in prescribed times.

Scrum allow requirements, architecture and design to emerge over the course of the project   So, let’s take a look more deep  and dive,by using the figure that we could describe in empirical model like this :

Product Backlog –> provides input to the define/build/test process

The Evaluation Activities –> provides an objective measure whether the code delivers the intended result (Passes all tests meets objectives criteria) –> So the decision maker in evaluation will define the next item on the backlog  which will always be addressed. If not, the software is reworked immediately until it meets the objective of the requirement.The practically framework of scrum iteration could  be generated like this :
  from the principle of scrum and the activities figure above , we have a little bit clear of scrum methodology . So , have a nice development and see you again.

cheers,
