How does Scrum fit into Agile Development?

While the Agile methodology can be applied to product development not only in the software industry but in other industries as well, Scrum is specific to software development.

Scrum is not a methodology. It simply provides structure, discipline and a framework for Agile development. The whole project is made up of a series of Sprints or Sprint Cycles (1 to n) where each Sprint is of the same duration. If ‘time’ is denoted by T, then T1 = T2 = T3 =… Tn. Sprints could be anywhere between 2 to 4 weeks. Sprints shorter than 2 weeks are not ideal and are used less frequently. At the end of each Sprint, a functional / working piece of software is produced that the users can actually test.

SCRUM     SCRUM is a type of Agile approach  It is a Framework not a Methodology    It does not provide detailed instructions to what needs to be done rather most of it is dependent on the team that is developing the software  Because the developing the project knows how the problem can be solved that is why much is left on them  Cross-functional and self-organizing teams are essential in case of scrum  There is no team leader in this case who will assign tasks to the team members rather the whole team addresses the issues or problems  It is cross-functional in a way that everyone is involved in the project right from the idea to the implementation of the project   The advantage of scrum is that a project   s direction to be adjusted based on completed work  not on speculation or predictions   Roles Involved   Product Owner  Scrum Master  Team Members  Agile Methodology    Build Software applications that are unpredictable in nature  Iterative and incremental work cadences called sprints are used in this methodology   Both Agile and SCRUM follows the system -- some of the features are developed as a part of the sprint and at the end of each sprint  the features are completed right from coding  testing and their integration into the product  A demonstration of the functionality is provided to the owner at the end of each sprint so that feedback can be taken which can be helpful for the next sprint   Manifesto for Agile Development      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 and Scrum are terms used in project management  The Agile methodology employs incremental and iterative work beats that are also called sprints  Scrum  on the other hand is the type of agile approach that is used in software development    Agile is the practice and Scrum is the process to following this practice same as eXtreme Programming  XP  and Kanban are the alternative process to following Agile development practice

At an outset what I can say is - Agile is an evolutionary methodology from Unified Process which focuses on Iterative  amp  Incremental Development  IID   IID emphasizes iterative development more on construction phases  actual coding  and incremental deliveries  It wouldn t emphasize more on Requirements Analysis  Inception  and Design  Elaboration  being handled in the iterations itself  So  Iteration here is not a  mini project by itself    In Agile  we take this IDD a bit further  adding more realities like Team Collaboration  Evolutionary Requirements and Design etc  And SCRUM is the tool to enable it by considering the human factors and building around  Wisdom of the Group  principle  So  Sprint here is a  mini project by itself  bettering a pure IID model   So  iterations implemented in Agile way are  yes  theoretically Sprints  highlighting the size of the iterations being small and deliveries being quick   I don t really differentiate between Agile and SCRUM and I see that SCRUM is a natural way of putting the Agile principles into use

As mentioned above by others   Scrum is an iterative and incremental agile software development method for managing software projects and product or application development  So Scrum is in fact a type of Agile approach which is used widely in software developments   So  Scrum is a specific flavor of Agile  specifically it is referred to as an agile project management framework   Also Scrum has mainly two roles inside it  which are  1  Main Core Role 2  Ancillary Role  Main Core role  It consists of mainly three roles  a   Scrum Master  b   Product Owner  c   Development Team   Ancillary Role  The ancillary roles in Scrum teams are those with no formal role and infrequent involvement in the Scrum procession but nonetheless  they must be taken into account  viz  Stakeholders  Managers   Scrum Master - There are 6 types of meetings in scrum    Daily Scrum   Standup Backlog grooming  storyline Scrum of Scrums Sprint Planning meeting Sprint review meeting Sprint retrospective   Let me know if any one need more inputs on this

Scrum is just one of the many iterative and incremental agile software development methods  You can find here a very detailed description of the process    In the SCRUM methodology  a Sprint is the basic unit of development   Each Sprint starts with a planning meeting  where the tasks for the sprint are identified and an estimated commitment for the sprint goal is made  A Sprint ends with a review or retrospective meeting where the progress is reviewed and lessons for the next sprint are identified  During each Sprint  the team creates finished portions of a Product    In the Agile methods  each iteration involves a team working through a full software development cycle  including planning  requirements analysis  design  coding  unit testing  and acceptance testing when a working product is demonstrated to stakeholders   So if in a SCRUM Sprint you perform all the software development phases  from requirement analysis to acceptance testing   and in my opinion you should  you can say SCRUM Sprints correspond to AGILE Iterations

Waterfall methodology is a sequential design process  This means that as each of the eight stages  conception  initiation  analysis  design  construction  testing  implementation  and maintenance  are completed  the developers move on to the next step   As this process is sequential  once a step has been completed  developers can   t go back to a previous step     not without scratching the whole project and starting from the beginning  There   s no room for change or error  so a project outcome and an extensive plan must be set in the beginning and then followed careful  ACP Agile Certification came about as a    solution    to the disadvantages of the waterfall methodology  Instead of a sequential design process  the Agile methodology follows an incremental approach  Developers start off with a simplistic project design  and then begin to work on small modules  The work on these modules is done in weekly or monthly sprints  and at the end of each sprint  project priorities are evaluated and tests are run  These sprints allow for bugs to be discovered  and customer feedback to be incorporated into the design before the next sprint is run   The process  with its lack of initial design and steps  is often criticized for its collaborative nature that focuses on principles rather than process
