Choosing the right software development methodology can make all the differences in the success of a project. There exist many methodologies and each has its own unique benefits and drawbacks. Understanding the needs of the project and the strength of each methodology is crucial in making the right choice. Choosing the wrong methodology can result in wasted time, money, and resources. Therefore, it is important to carefully consider all options before deciding on a software development methodology. In this blog post, we will examine one of the most common software development approaches – Agile, which is widely utilized by both large enterprises and SMEs.
What Is Agile Software Development?
Agile software development is a modern approach to software development that emphasizes flexibility and adaptability. Instead of following a rigid plan, agile members work iteratively, collaborating closely with both developers and clients to continuously refine and improve the software as it is developed.
The goal of agile development is to create software that is responsive to changing needs and priorities, delivering value to customers more quickly and effectively than traditional development methods. Teams using agile methodologies typically work in short, focused sprints, testing and refining their code throughout the development process. By welcoming change and promoting collaboration, agile development helps teams achieve better outcomes and deliver better software more efficiently.
The 4 Main Values & 12 Principles Of Agile Development
In 2001, 17 software development professionals came together to discuss a new approach to their field, an approach that would prioritize agility over rigidity and adaptability over strict adherence to a plan. These professionals were looking to create a methodology that would allow for faster and more efficient software development, while still producing high-quality results. The result of their collaboration was the Manifesto for Agile Software Development, a set of guiding principles for software development that are still widely in use today.
We can understand the core foundation of Agile methodology through its four values:
Generally, Agile development prioritizes efficient software creation, close customer collaboration, and easy adaptability to changes. This approach proves highly advantageous for complex projects or those with uncertain requirements.
Regarding Principles behind the Agile Manifesto, there are 12 core things in the software development process:
1/ Meet customers’ satisfaction through early and continuous beneficial of work.
2/ Accept changes.
3/ Deliver the work frequently, with a short timescale.
4/ Business members and project developers have to collaborate together throughout the process.
5/ Motivate every member with the environment and assistance they require.
6/ Emphasize direct/face-to-face communication.
7/ Measurement of the progress is the working software.
8/ Sustainable development is highly acknowledged.
9/ Continuously look for excellence.
10/ Simplicity is the key.
11/ Best work emerges from self-organizing teams.
12/ Teams have to reflect on how to become better.
Agile Software Development Life Cycle (SDLC) Flow
The agile software development life cycle can be broken down into these following stages:
In the concept stage, it is important to identify potential business opportunities that might arise from the project. This means taking a strategic approach, analyzing the market and assessing the potential demand for your product or service. It’s also crucial to estimate the necessary time and effort needed to complete the project. This ensures that you have a realistic timeline and resources in place to execute the project to the best of your ability.
The second stage, known as inception, is crucial for setting the foundation of any project. During this phase, team members are identified to ensure that everyone is aware of their roles and responsibilities. Funding is also put in place at this point, and the project requirements are discussed with the client. To ensure that the project stays on track, a timeline can also be generated to outline and define specific tasks which are expected to be completed.
Regarding iteration phase, the team will begin to work on actual tasks and develop the product. Time is spent on coding and creating designs of the product to ensure that it meets customer expectations. This phase involves continuous feedback and course corrections if needed.
The fourth stage is release in which the final product of a project is delivered to customers or stakeholders. During this phase, any remaining quality assurance tests should be conducted, and any remaining bugs should be fixed.
Lastly, the fifth stage of the life cycle is production. This involves making sure that the project is efficiently running and monitored to prevent any potential issues from occurring. Any necessary maintenance tasks or upgrades will also take place at this stage.
Types Of Agile Framework
Agile has gained significant popularity in the software development world over the years. It is a dynamic approach to project management that emphasizes iterative and incremental delivery, fostering flexibility and a collaborative work environment. With about 41 comprehensive Agile methodologies, it can be challenging to select the one that fits the team’s unique needs. However, most software development teams and projects tend to stick with the several most established Agile frameworks. These include Scrum, Kanban, and Lean, among others. Each framework has its unique emphasis, benefits, and challenges, but they all share the same core values that Agile is built upon.
Scrum – Scrum is one of the most popular Agile frameworks. It focuses on delivering small chunks of value repeatedly throughout the development process. Teams break down their project into smaller tasks, known as sprints, and then work together to complete them within a specific time frame. This process encourages collaboration and ensures that customer feedback can be incorporated quickly in the product before it is released.
Kanban – Kanban is another popular Agile framework. It works similarly to Scrum but does not involve the same time-based sprints. Instead, it relies on a visual board with tasks that move through various stages of completion until they reach the end goal. This allows teams to track progress more easily and ensure that no steps are missed or delayed during the development process.
Lean – Lean is a framework that focuses on eliminating waste and building customer value. It employs Agile principles of continuous improvement to ensure that teams are continuously optimizing their processes in order to maximize efficiency and minimize wastage. By implementing lean practices, teams can identify which steps are unnecessary and streamline the development process accordingly.
Extreme Programming – Extreme Programming (XP) is a methodical approach to software development that emphasizes the delivery of top-notch software in a quick and continuous manner. With the ever-changing needs of customers, XP strives to improve the quality and responsiveness of the software. Through active participation of the customer, frequent feedback loops, continuous testing, meticulous planning, and relentless teamwork, XP aims to deliver working software at frequent intervals, usually every 1-3 weeks.
Feature Driven Development (FDD) – FDD is an iterative and incremental software development process that emphasizes the delivery of features in a structured manner. It involves breaking down large projects into smaller functional units, known as features, and then creating individual plans for each feature. This ensures that all aspects of the project are addressed in an orderly fashion.
Crystal – The Crystal methodology stands out for its adaptability and focus on people and interactions. Unlike other methodologies that take a one-size-fits-all approach, Crystal recognizes that every project is unique and requires a tailored set of policies, practices, and processes. What sets Crystal apart is its emphasis on the criticality and priority of the system being developed. With Crystal, the team understands that the people involved in the project and the interactions between them are just as important as the end result. By prioritizing both, Crystal offers a powerful framework for delivering successful projects with a human touch.
