Agile-is a software development process that has been adopted by many companies and organizations. In fact, It’s existence is originally an alternative to the more traditional waterfall approach, which consists of extensive up-front requirements gathering, planning, and documentation.
Agile software development life cycle in software Engineering is working in short cycles (called “sprints”) with regular feedback from users along the way to empathize on efficiency and delivery time and allow quick response to changing requirements, which is vital in this fast-paced industry.
Agile project management is based on iterative and incremental development while encouraging feedback from customers and the team, and it allows for quick changes to the product.
In this section, we will provide an introduction to agile principles and how to use it in different industries.

What is agile methodology?
There are 5 stages of its development also known as agile SDLC phases and they are a set of stages that are repeated till time runs out or the project is done.
The methodology consists of a set of stages and they are:
Define the problem:
Firstly, The first step in agile methodology is to define the problem. This helps to identify the issue and figure out what you need to do.
Understand the problem:
When you are working on a new project, it is important to understand the problem that you are solving.
Create solutions:
The software developers brain storm the best solutions and develop it further -The team tests their solution with users, receiving feedback on how to improve and work on it.
Implement solutions:
This is where the developers find the best solution to the problem as well as start implementing it into their project and test it again with users.
Repeat stages 1-5 until you achieve all your goals
We agreed that the agile process is a short and repeatable cycle, this is where you start all over from step 1 over and over again till you complete your project.
Those steps of this software development ensure:
– Improved collaboration among the team members.
– Reduced risk and increased flexibility.
– Increased productivity.
– Improved quality.
Agile manifesto
It is the document that contains the principles of agile. It has 12 principles written by 17 software developers from around the world in February 2001.
Here are the principles:
- Satisfying customers through early and continuous delivery of valuable work.
- Breaking big work down into smaller tasks that can be completed quickly.
- Recognizing that the best work emerges from self-organized teams.
- Providing motivated individuals with the environment and support they need and trusting them to get the job done.
- Creating processes that promote sustainable efforts.
- Maintaining a constant pace for completed work.
- Welcoming changing requirements, even late in a project.
- Assembling the project team and business owners on a daily basis throughout the project.
- Having the team reflect at regular intervals on how to become more effective, then tuning and adjusting behavior accordingly.
- Measuring progress by the amount of completed work.
- Continually seeking excellence.
- Harnessing change for a competitive advantage.
What are the types of agile model in software engineering?
Agile processes is a set of principles for a software development methodology that emphasizes collaboration while focusing on communication, self-organization, and working software as its core values.
The most popular types of its models in software engineering are:
1) Scrum:
what is scrum agile? It is one of the most popular models, you can use it for managing complex product development with many requirements.
2) Kanban:
This type of model focuses on limiting work in progress to reduce the amount of time before product release.
3) Lean start-up:
This type of model focuses on fast cycles where you create small iterations to test the assumptions.
What is Extreme programming (XP)?
Extreme Programming also known as XP is an agile software development approach that attempts to deliver better software while also improving the development team’s quality of life. In terms of proper engineering methods for software development, XP is the most detailed of the frameworks.
XP’s general qualities are:
- Software requirements that are always changing
- Projects with a set deadline that leverage new technologies pose risks.
- Extended development team with a small, co-located size.
- Unit and functional tests that can be automated with the technologies you’re utilising.
nimble, spry, supple, limber and lithe are synonyms for agile but developers prefer to call it agile to unite the use of that term as well as the principles that makes Agile software development one of the best processes out there.
