Agile in software development

Agile is a very popular modern approach to software development. Agile was developed in direct response to the high failure rate of software development projects. A group of developers wanted to create an approach that would allow others to succeed in their projects and be happier while doing so.

The approach is guided by the Agile Manifesto which includes certain principles and rules for best practice. There is a very specific premise to the agile approach that underpins all work being done on any agile project. For this reason, many people working within software development will undergo specific Agile training courses and qualifications to be able to work effectively within the methodology. 

The Agile methodology has a lot of unique benefits to offer the world of software development. It is a successful, effective, and enjoyable approach that allows the best experience possible for both those carrying out the software development work and those on the receiving end of the product being developed. 

In this blog, we are going to discuss the Agile approach in more detail and how exactly it can be useful. 

Starting with…

The Agile Manifesto 

The Manifesto for Agile software development was developed in the 1970s and is still used to guide and structure Agile projects. It sets out the values, goals, and expectations for agile projects and how they should be carried out so that they may be as successful as possible.  

The Manifesto states…

“We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:

  • Individuals and interactions over processes and tools
  • Working software over comprehensive documentation
  • Customer collaboration over contract negotiation
  • Responding to change over following a plan

That is, while there is value in the items on the right, we value the items on the left more.” 

The Manifesto aims to rid the field of software development of the things that are holding it back, i.e. rigidity, micromanagement, and excessive documentation, and replace these with more responsive and appealing options. The main focus of the Agile Manifesto lies in valuing both the client and the development team, prioritising collaboration, and working effectively. 

The team behind the Manifesto believed that following these principles would allow developers to rise above the negative patterns that were forming in the field and forge their own path to efficiency and positive outcomes in development projects. 

The Agile software development life cycle

As in all software development methodologies, there is a way of working commonly followed by Agile projects. This is known as the Agile software development life cycle. 

There are six stages of the agile software development life cycle, which are…



During the first stage of the Agile SDLC, requirements, documentation, and plans are developed. As we have noted, the Agile approach is very collaborative so there will be a big focus on the client at this stage. One of the ultimate aims of Agile is to provide software clients with valuable software that meets their needs and requirements. Therefore, it is crucial to be clear on what these are before any work begins on the project. 

Time, cost, and deadlines may also be considered and decided upon at this stage, with the client being consulted and informed at every step of the way.



Agile projects have specific roles, including scrum master. At the inception stage of the SDLC, these roles will be made clear to the members of the development team and whose responsibility is what will be decided upon and communicated. Agile projects rely heavily on teamwork and so making these roles clear is a key aspect of the process. 



The iteration stage of an Agile software development life cycle is arguably the most important. Agile projects are structured as a series of iterations in which work is designed, developed, tested, and given to stakeholders and clients for feedback and approval. This feedback is used to create the next iteration, which fixes any issues. This continues for the entirety of the project and ensures that the client is thoroughly involved with all work developed. It is a collaborative development progress that requires input and effort from both sides. 



The release phase of the agile SDLC includes quality assurance and testing to prepare the product for its final release to end users. After this testing, one final iteration of work is carried out to make sure that any last fixes are sorted before the product is deployed. As you can see, there are many steps of approval that allow the highest quality product to be created before anything is seen by end-users. This process is what sets Agile aside from other methodologies. 



A live version of the product is being used by its target audience at this point in the project’s life cycle. However, the work is not finished yet. The development team will provide ongoing maintenance and support during this phase. They will verify that the system runs smoothly and check for bugs. On a more long-term basis, they may also work with updates, upgrades, and new features when necessary. Everything is put in place to make sure that the product developed continues to be of high value to its target user base both now and into the future. 



This final stage of the Agile life cycle may occur later in the future when a product needs to be replaced or it has become obsolete to its users. Depending on the situation, the software development company may be able to provide support in terms of closing down the system, removing customer support, and assisting with any data migration. Even when closing down a project, the Agile methodology offers collaboration and support. 

The benefits 

There are many benefits involved for both software development companies and clients when it comes to using Agile approaches in software development. These include (but certainly are not limited to)…


  • Regularly presented results and feedback opportunities increase client satisfaction and transparency 


  • The iteration structure provides regular opportunities to improve the product and fix bugs or errors


  • Problems can be fixed and changed early on which allows bigger problems to be avoided and quicker testing cycles 


  • Changes made at any time throughout a project and change is embraced as a positive aspect of projects


  • Solid communications lines between client and company allow for good relationships to be built throughout the project 


  • Fast building and delivery of the product, leading to decreased time to market period and overall shorter project times 


  • Lower costs due to reduced documentation and increased efficiency in production


  • Clients can see their deadlines and schedules for delivery in advance thanks to sprints


  • Increased overall quality of products created
