scrum is an agile framework which gives highest business value to customers in short period of time.

Core Values
  • Transparency
  • Inspection
  • Adaption
Kay Roles

Product Owner
  • Creates and maintains a prioritized wish list called a product backlog. 
  • Responsible for maximizing the value of the product and the work of the Development Team
Scrum Master
  • Responsible for ensuring Scrum theory, practices and rules. 
  • Servant-leader for the Scrum Team

Development Team

  • Teams are self-organizing cross-functional
  • Individual Development Team members may have specialized skills and areas of focus, but accountability belongs to the Development Team as a whole.
Key Terms
  • Scrum Team - Product Owner, Scrum master and Development team
  • Sprint- Iteration. This is time boxed(Generally 2-4 weeks) . 
  • Sprint backlog- Backlog Items selected for the sprint.

Agile software development

Today we hear this word “Agile” every where. So it is better to get some knowledge on agile.
  • What is it?
  • Who invent this?
  • What are the core values and principles?
  • What are the advantages of it?
  • What are the frameworks facilitated for this?

What is Agile software development?
Agile software development is an iterative and incremental development process which gives the maximum business value in short period of time. It focuses on keeping code simple, testing often, maintaining working software end of each increment and delivering functional bits of the application as soon as they're ready. Also it anticipates the need for flexibility and promotes the continuous improvement. 

Who invent this?
Set of experts who use various iterative and incremental software development methods (Eg: SCRUM, XP…)  which evolve requirements and solutions evolve by collaboration get together and introduced the Agile Manifesto in 2001.They come up with set of principles all the which suite for all those software development processes. So Agile is an all the iterative and incremental software development methods.

What are the core values?
  • Individuals and interactions over processes and tools
  • Working software over comprehensive documentation
  • Customer collaboration over contract negotiation
  • Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.

Agile principles

  1. Highest priority is to satisfy the customer through early and continuous delivery of valuable software.
  2. Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
  3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
  4.  Business people and developers must work together daily throughout the project.
  5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
  6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
  7. Working software is the primary measure of progress.
  8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
  9. Continuous attention to technical excellence and good design enhances agility.
  10. Simplicity--the art of maximizing the amount of work not done--is essential.
  11. The best architectures, requirements, and designs emerge from self-organizing teams.
  12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.  
What are the advantages of it?
  1. Giving the maximum value to the customer in short period of time. 
  2. Development done according to the highest customer value.Start from low risk and high value functionalists and then go for complicated features.
  3. Ability to support changing needs of the customer.
  4. As Customer can see the working software demonstration, he can have a good understand on their product rather than reading lengthy documentations. Also and he can provide his inputs. 
  5. Promote the continuous improvement of the product, development process, development teem.
  6. Minimise the failing risk of the project.
