Agile in Software Development:
Agile is one of the world’s most widely used and recognized software development framework.
Most of the organizations have adopted it in some form or the other but there is still a long way to go in the maturity of their adoption programs. The sole aim of this series of tutorials is to onboard technology and non-technology professionals into the Agile World.
We will take you through the agile journey in a step by step manner until you understand the philosophy behind using Agile, its advantages and how to practice it. This series aims to equip and enable the readers to apply Agile and Scrum learning into their work.
This particular tutorial is dedicated for explaining to you why there was a need for Agile and how it got created. The fundamental here is to make you understand the concept of Agile Adoption in Software Development Industries.
History of Agile
Agile was born when on one fine day when 17 people with differing development methodologies background, got together to brainstorm if there was a possible alternative solution to software development which could lead to faster development time and was less documentation heavy.
At that time, software development used to happen so long that by the time projects were ready to be delivered, the business had moved ahead and the requirements had changed. Thus a project was not able to meet the business needs even if it was able to meet its defined objectives.
Thus these champions of different software engineering techniques got together and the end result of their meeting was what they called the “agile manifesto’ which we will be discussing in detail in the next tutorial of this series.
But the agile that was born that day is not what we see today in organizations. The methodology those experts agreed upon was described as ‘lightweight’ and fast. But the main win out of this meeting was the thought that faster delivery of a product and constant feedback were the keys to achieve success in software development.
The existing waterfall techniques were too cumbersome and had no provision for feedback until the final product was ready to be delivered. This meant that there was no scope for course correction and the customer had no view on the progress until the whole product was ready. And that was what these experts wanted to avoid.
They wanted a solution which would have a scope for constant feedback in order to avoid the cost of rework at a later stage.
The existing waterfall techniques at that time were too cumbersome and had no provision for feedback until the final product was ready to be delivered. It was called a waterfall model of development because the teams first finished one step completely and only after that they moved ahead to the next step.
This meant that there was no scope for course correction and the customer had no view on the progress until the whole product was ready. And that was what these experts wanted to avoid. They wanted a solution which would have a scope for constant feedback in order to avoid the cost of rework at a later stage.
And that is why agile is also about being the adaptive and continuous improvement, as much as it is about constant feedback and speed of delivery.
What are Agile Promises?
Agile is not only about applying the set practices in developing a software. It also brings in a change in the Team’s mindset which drives them towards building a better software, working together and eventually landing them a happy Customer.
Agile values and principles enable the team to shift their focus and change their thought process of building a better software.
What Exactly is Agile?
Agile is not a set of rules. Agile is not a set of guidelines. Agile is not even a methodology. Rather, Agile is a set of principles that encourage flexibility, adaptability, communication and a working software over plans and processes. It is very succinctly captured in what is called the agile manifesto.
Agile software development allows the team to work together more efficiently and effectively in developing complex projects. It consists of practices that exercise iterative and incremental techniques which are easily adopted and display great results.
In apply Agile into action, we have various Agile-based methods and methodologies. These methods and methodologies cater all the needs of a software development industry right from the software design and architecture, development & testing to project management and deliveries.
Not just that, Agile methods and methodologies also open a scope for process improvement as an integral part of each delivery.
Agile is a software development approach where a self-sufficient and cross-functional team works on making continuous deliveries through iterations and evolves throughout the process by gathering feedback from the end users.
How to Practice Agile?
There are various Agile Methodologies that are in practice in various diversified industries.
However, the most popular methodologies amongst all of them are:
- Extreme Programming
All these methodologies focus on lean software development and help in building better software effectively and efficiently.
That is all with Agile Introduction. The part is structured to help you to understand the core values and principles that shall be adopted for a team to be working in an Agile mode and mindset.
