Agile development as a renowned and updated methodology in Project Management, consists of a group of development methodologies that help evolve requirements & solutions through the coordination of self-organizing cross-functional teams. It facilitates focused & streamlined project management, through a consistent review teamwork and a sense of responsibility. As a set of best practices, Agile allows optimum delivery in terms of time & quality and contributes towards accomplishment of organizational goals. Processes for development are basically picked up from the agile manifesto developed by some of the connoisseurs in the software industry.
Scrum, a subsection of Agile, is a process framework of agile development and is most prominent one also. It’s a collection of practices to be implemented and adhered to keep process in line with the framework. The terminology used for Scrum is lightweight, which actually means that the process has a small overhead so as to yield an optimum productive time available for accomplishing all valuable work. One of the crucial advantages of Scrum over other methodologies is that if a feature in an iteration fails, it doesn’t impact other features. So, planning and execution of other iteration continuous and the end iteration can still be released.
Agile is distinct from Scrum through certain concepts and practices which are segregated into 3 classes i.e. Roles, Artifacts and Time Boxes. It contributes towards achievement of organizational goals by enhancing quality of deliverables, adapting with changes, offering better estimates through a reduced time span and controls the project schedule in a much better way.
Scrum consist of a Sprint, which is a basic unit of development. Every Sprint commences with a planning meeting, wherein the relevant responsibilities are recognized and an assessment of obligations for that Sprint are outlined. It is followed by conduct of reviews for reflective meetings to consider growth and establish accountabilities for the following Sprint. Each Sprint ends with a portion of the final product.
On the other hand, the Agile method progresses with every iteration comprising a team serving towards a full software development cycle including planning, requirements analysis, design, coding, unit testing, and acceptance testing at the time of demonstration of a finished product. In a way, we can say that Scrum is an agile process framework in a very specific arrangement. Frameworks like Scrum and Kanban in software development are both distinct arrangements of Agile Methodology. To have a clearer comprehension, if Agile is fundamental principles than Scrum is a specific example of those principles.

There are various steps involved in the Scrum process. Let us have a look for better understanding:
It provides space and chance to team members for sharing their concerns and comprehends workflow to the core.
Each iteration is initiated with s Sprint Planning Meeting. Usually, the product owner arranges a meeting to have a conversation with the team and elects what stories hold higher degree of priority and which one will be tackle primarily. These stories get added into the Sprint Backlog and the team then segregates the stories into smaller tasks.
Another name for this is Daily Standup Meeting. Its serves the purpose of compressing communication and ascertaining that the whole team is progressing in coordination. Every team member ensures awareness about what was done till the last stand up, plans how to work on the next one and defines any obstacle if present.
Sprint Review Meeting:
At conclusion of every Sprint, all the teams exhibits their work to the client (product owner), who then goes through the Sprint Backlog to either accept or reject (including all the incomplete stories) the work.
Sprint Retrospective Meeting:
At the end of every Sprint, The Scrum Master coordinates with the team for a reactive kind of meeting to discuss the success and failures of the project including what they did well, what went wrong and what can be improved in future Sprints. The client (Product Owner) being present in the meeting, share views as well, so that the complete team gets a panoramic view of the performance and recognizes strategies for enhancing the process. These meetings are crucial as at these stages Scrum Master can find weaknesses in the process and look for the solution of the same.
