Scrum is an agile method of managing a project, basically software development. Scrum agile software development often is considered as methodology but instead of regarding it as methodology; you might consider it as a framework to manage a project. It is a control and management process which cuts through the complications for focusing on developing products which fulfill business requirements. Teams and management have the ability of getting their hands around the technologies and needs and deliver the working products empirically and incrementally.
Scrum depends on a cross-functional, self-organizing team. The self-organizing scrum team has no team leader who determines which individual would do task or in what ways an issue would be settled. The team decides these issues as a whole. In cross-functional scrum team, everyone has to take one feature from idea to that of implementation. Well, two particular roles support the scrum team within the agile development. The first one is the ScrumMaster, who could be regarded as a coach for the team, assisting members of team to utilize the Scrum process for performing at the highest level. The other role is of the product owner, who represents the enterprise, users or customers as well as guides the team to build a perfect project.
The Scrum process was framed by Kern Schwaber and Jeff Sutherland in the early 90’s. It was codified in 1995 for presenting it at the OOPSLA conference in Austin and published the ‘SCRUM Software Development Process’ paper. The term ‘Scrum’ was inherited by Ken and Jeff from groundbreaking paper of 1986 ‘The New Year Product Development Game’ by two recognized management thinkers, Nonaka and Takeuchi. They, with the name ‘Scrum’ referred to the rugby game for stressing the significance of team and analogies between team sport such as rugby and to be successful in the new product game. The research explained in the paper showed that excellent performance in the formation of new, complicated products is gained while teams, being a self-organizing and small unit of people, are rendered objectives but not with works.
In the process of using and developing early Scrum versions, Ken said the popular process control research engineer Professor Babatunde A. Ogunnaike Tunde to take a look at the processes of software development. Investigating various commercial methods of commercial software-development, he concluded that the predictive and waterfall process is not a correct fit for the software development work. Tunde confirmed that empirical Scrum approach is the preferred process. Scrum first tried as well as refined at Individual, IDX, Inc., and Fidelity Investments. The Scrum Guide got its first publication in 2010 and incremental updates in the year 2011 and 2013. With it, Jeff and Ken formed the worldwide recognized body of Scrum knowledge. Various companies of software development have adopted Scrum and at present it is the most applied method for agile software development.
Early advocates of Scrum were encouraged by verifiable inspect and adapt feedback loops for coping up with risk and complications. Scrum prioritizes decision-making from results of real-world instead of speculation. Time is parted into short work cadences, called as sprints, typically 1to2weeks long. The product is placed in a powerful shippable state every time. At the end of every sprint, team members and stakeholders meet to see potentially demonstrated shippable product increment.
Scrum is simple set of responsibilities, meetings and roles which never change. It is opposite of huge collection of interwoven mandatory elements. It is not a methodology and applies the scientific process of empiricism. Scrum replaces an approach of programmed algorithmic with heuristic approach, with respect to self-organization and people for dealing with solving complicated and unpredictable issues.
The main artifact in Scrum development is itself the product. The Scrum model is of the expectation that team will bring the system or product to a strong shippable state at the end of every Scrum sprint. The other artifact is the product backlog. This is a complete functionality list which remains for adding to the product. The product owner emphasizes the backlog so that the team operates always on the most beneficial features.
During the planning meeting and first day of sprint in Scrum project management, team members develop the sprint backlog. It can be considered as to-do list of the team for the sprint while product backlog is list of features that needs to be built. The sprint backlog is a list of works that team requires doing for delivering the functionality that it promised to offer during sprint.
Agile is the capability of creating and responding to change for succeeding in turbulent and uncertain environment. It is an umbrella term for a set of practices and methods based on principles and values manifested in Agile Manifesto.
Various methods started to achieve enhanced public attention, each having a distinct combination of new and old ideas. These methods prioritized close alliance between the business stakeholders and development team; frequent business value delivery, rigid, self-organizing teams and smarter techniques to craft, confirm as well as deliver code. In early 2001, seventeen practitioners of software development gathered in Snowbird where these methodologies were applied the term ‘Agile’. The joint collection of principles and values was manifested in the Manifesto for Agile Software Development.
The ScrumMaster is the coach of team and aids practitioners of Scrum to attain the highest-level of performance. A reliable ScrumMaster protects the team for external distractions, letting the team members to offer attention during sprint on the selected goal. It helps the team to be the most efficient that it could be and the product owner functions for directing the team to the correct goal. The product owner is liable to prioritize the backlog at the time of Scrum development. The final role in project management of Scrum is the team itself. Individuals could join the team with several job titles as these are not important in Scrum. Scrum Methodology asserts that every person contributes in the way they could to finish the work of every sprint.
The Scrum team is itself the vehicle that is ready to speed across any direction. The product owner is the driver that ensures that the vehicle is always moving in the correct direction. The ScrumMaster is the main mechanic that assures to keep the vehicle well-tuned and make it perform the best.
