Comparison of SDLC Methodologies
Definition and Purpose of each methodology
Scrum is a management framework that teams use to self-organize and work towards a common goal. It describes a set of meetings, tools, and roles for efficient project delivery. Much like a sports team practicing for a big match, Scrum practices allow teams to self-manage, learn from experience, and adapt to change. Software teams use Scrum to solve complex problems cost-effectively and sustainably.
The Agile methodology is a way to manage a project by breaking it up into several phases. It involves constant collaboration with stakeholders and continuous improvement at every stage. Once the work begins, teams cycle through a process of planning, executing, and evaluating. Continuous collaboration is vital, both with team members and project stakeholders.
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes. This speed enables organizations to better serve their customers and compete more effectively in the market.
Scope of each methodology
With the Agile or Scrum approach what is to be done in a given project is not held constant and changes can be added. The scope becomes variable but time and cost are considered constants. The overall project length is broken down into equal-length time periods called sprints. In the framework of Scrum, each sprint becomes a project in itself, and hopefully, at the end of the sprint (which is commonly thirty days long), there will be increments that are completed or “done” that can be turned over to the user for implementation.
On the other hand, the scope of DevOps spans system integration and deployment and allows the automation of multiple processes throughout the entire software development lifecycle.
