Every enterprise wants to deliver high-quality software to the customer in less time. However, balancing quality and time is a tedious task.
In a race to deliver a quality product to the customer faster than competitor enterprises are adopting new-age methodologies like agile and DevOps.
Usually, it is seen that larger enterprises are change-resistant due to several reasons such as deep-rooted cultural issues, and policy- and process-based barriers.
Despite these reasons, some enterprises have been successful in reaping the benefits of agile methodologies.
Let us now try to understand this methodology in more detail.
What is agile methodology?
It is a software development and testing approach that follows certain values or principles stated in the agile manifesto for software development.
The main aim of this methodology is to deliver robust software to end-user to maximize customer satisfaction. The agile approach promotes continuous iteration of development and testing throughout the software development lifecycle.
In this model, both development and testing activities are concurrent, unlike the waterfall model.
What are the agile methods in software engineering?
Extreme Programming (XP): This methodology is very useful for projects that require constant changes and quick delivery of software to end-users. It ensures continuous development and customer satisfaction and uses scrum-like cycles or sprints.
It includes customer interaction, team member’s participation, quick feedback loops, test-driven growth, and one to three weeks shorter iterations. XP is applicable in the following situations:
Dynamically changing software requirements
Risks associated with fixed time projects using new technology
If the development team is small and co-located
The technology you are using allows for automated unit and functional tests
Kanban: Kanban follows the Lean and Just-In-Time approach of production that states- ‘what to produce when to produce it and how much to produce.’ It is a non-disruptive evolutionary change management system.
In this methodology, existing processes are improved in small steps by implementing small changes that reduce overall risk to the system. This framework is used to implement agile and DevOps software development.
It requires real-time communication and full transparency of work. Agile teams working with this methodology make use of a kanban board in which work items are represented visually that allows team members to stay updated with the state of work at any time.
Agile Scrum Methodology: Scrum is a lightweight agile project management framework that is used to manage iterative and incremental projects where each project consists of two to four-week sprints.
Unlike other methodologies, the focus is on building the entire product in a single iteration from start to finish. This methodology emphasizes delivering several iterations of a product.
Lean Software Development: It is an iterative type of agile methodology and it aims to deliver a high-quality product to customers.
The lean methodology is also known as the MVP technique i.e. Minimum Viable Product in which a team launches a minimum viable version of the product to the market and observes what the customer likes, dislikes, or wants in a product, based on which the teams iterate and take actions to improve the product.
Scaled Agile Methodology (SAFe): It is an extension of agile methodology that helps larger organizations overcome issues that negatively impact project success.
It offers large organizations a framework for becoming more agile so that their deliverables take less time-to-market.
It contains a set of principles, processes, and best practices that help enterprises to adopt agile methodologies, such as Lean, Kanban, and Scrum, to develop and deliver high-quality products and services faster. It is built on three pillars i.e. team, program, and portfolio.
Conclusion:Agile approaches in software engineering have gained much importance in recent times due to the benefits that it provides to IT teams.
With the help of these methodologies, a work culture driven by communication and collaboration is developed in an organization which helps in delivering a quality product to the customers faster.
Leverage agile testing from a next-gen QA and software testing services provider to achieve quality software that delivers a great CX.
