What is Scrum?

SCRUM is a lightweight framework that helps people , teams and organizations generate value through adaptive solutions for complex problems. It consists of scrum team and accountabilities , scrum events, scrum values and scrum artifacts and it provides an agile way of thinking.

what is agile
agile is a method of project management used especially for software development that is characterized by the division of tasks into short phases of work and frequent reassessment and adaptation of plans based on feedback.

Contrasted with waterfall agile is a time boxed , iterative approach to software delivery that builds software incrementally from the start of the project , instead of trying to deliver it all at once near the end (waterfall).

It uses fixed-length iterations called sprints (usually 2 to 4 weeks each) to do work in bits. Based on the ancient "Divide and conquer".

The 3 Empirical Scrum Pillars

• SCRUM combines four formal events (Scrum planning, Daily Scrum , Scrum review and Scrum retrospective) for inspection and adaptation within a containing event, the sprint. These events work because they implement the empirical scrum pillars of TRANSPARENCY, INSPECTION AND ADAPTATION

SCRUM values - successful use of scrum depends on people becoming more proficient in living five values.

PRODUCT OWNER

• Responsible for maximizing the product value (ROI) of the
  
  development effort and is accountable for the product backlog
  
  value.




• Responsible for the vision of the product




• Manages the product backlog (list)
  
  
  (prioritize and re- prioritize)




• Final referee of the questions on requirement.




• Accept or reject each product increment : it focuses on the
  
  "WHAT" and not the "HOW".




• Decide what is released and when.




• Consider the interests of stakeholders.




• Has a leadership role.

DEVELOPERS(DEVELOPMENT TEAM)

• Cross functional




• Self-organized/self-managed, with no externally assigned roles or external influence.




• Negotiate commitments with the product owner, one sprint at a time to set sprint goals based on a sprint backlog.




• Has autonomy with respect to how to achieve its commitments.




• Build a deliverable increment on each sprint.




• Intensely collaborative.

SCRUM MASTER

• Facilitates the scrum process




• Causing the removal of impediments to the scrum team's progress;




• Create an environment to enable self-management capture
  
  empirical data to adjust forecasts and protects the scrum teams
  
  from external distraction

PRODUCT BACKLOG (ARTIFACT)

• This is the list of everything that is going to be done.




• If it is not in the backlog it is not done.




• Prioritized or ordered by the product owner (force-ranked).




• Usually written in the form of a "user story".

SPRINT BACKLOG (ARTIFACT)

What you commit to do RIGHT NOW , to meet the goals of the current sprint. It is chosen from the content in the product backlog.

DAILY SCRUM MEETING

RETROSPECTIVE MEETING

INFORMATION RADIOTOR

• Information radiators are highly visible charts and figures
  
  displaying.




• Project progress and status e.g. Kanban boards, burn-down
  
  charts ,these shows the real progress and performance of the
  
  project and team which enhances transparency and trust among
  
  team members and other stakeholders.

USER STORIES

The stories uses non-technical language to provide context to the development team and their efforts, after you read user story the team knows why you are compiling what you are compiling and what value it creates.
