1. What are Agile Methodologies?

1.1. Definition

Agile methodologies are a group of project management frameworks that emphasise flexibility, iterative development, and customer collaboration. Due to its advantages, software developers often use these methods, and apply them to any project where the requirements are constantly changing or where the team needs to be able to adapt to new information quickly.

1.2. 4 Key Values

  • Individuals and interactions over processes and tools: Agile teams value the interactions between people over the use of processes and tools. They believe that people are more important than processes and the best way to get things done is to work together.
  • Working software over comprehensive documentation: Agile teams focus on delivering working software over creating comprehensive documentation. They believe that it is more important to get the software into the hands of users so that they can provide feedback and make improvements.
  • Customer collaboration over contract negotiation: Agile teams collaborate with customers throughout the development process. They believe that it is important to get customer feedback early and often so that they can tailor the software to meet their needs.
  • Responding to change over following a plan: Agile teams are able to respond to change quickly and easily. They believe that it is more important to be able to adapt to change than to stick to a rigid plan.

1.3. 12 Principles

  • Customer satisfaction: The highest priority is to satisfy the customer through both early and continuous delivery of valuable software.
  • Welcome changes: Even if it is late in development, Agile processes harness change for the customer\’s competitive advantage.
  • Deliver frequently: Increments of functionality should be delivered frequently, whether it is a few weeks or a few months, with a preference for shorter timescales.
  • Work together: Businesses and developers must work together daily throughout the project, this could finally reduce the risk of project development.
  • Motivated team: Give them the environment and support they need, and trust them to successfully finish the job.
  • Face-to-face interactions: The most effective method of conveying information to and within a development team is face-to-face conversation.
  • Working Software: Working software is often the best documentation. Project managers and businesses undoubtedly need to focus on minimising paperwork and maximising productivity.
  • Sustainable Development: Agile processes promote sustainable development. For this reason, the sponsors, developers, and users should be able to maintain a constant pace indefinitely.
  • Technical excellence & Good design: The software development team should take time to review their code and make them better with each iteration, which will save them more time than cleaning up code later.
  • Simplicity: Keep things simple and minimise the time between comprehension and completion. Moreover, remember to avoid doing things that don’t matter
  • Self-organising teams: Teams should be allowed to self-organise around their work. 
  • Inspect & Adapt: Identify and adjust the behaviour and process that most effectively enables them to deliver value to their customers in the long run.

2. How Agile Differ from Traditional Software Development Life Cycles (SDLCs)

In general, Agile and traditional software development life cycles (SDLCs) are two different approaches to software development. Agile methodologies are designed to be flexible and adaptable

Firstly, Agile methodologies emphasise iterative planning, where teams plan for the next sprint or iteration based on what they have learned in the previous sprint or iteration. 

Secondly, Agile methodologies emphasise communication and collaboration between team members and stakeholders throughout the development process. 

Thirdly, Agile methodologies typically produce less documentation than traditional SDLCs. Agile teams believe that working software is more important than documentation, and that documentation can be created as needed. 

Moreover, Agile methodologies emphasise continuous testing, with teams testing their code frequently throughout the development process. 

Lastly, Agile methodologies embrace change, and teams are expected to adapt to change quickly.

3. Top 10 Agile Software Development Methodologies

3.1. Agile-Waterfall

Agile-Waterfall is a hybrid methodology that basically combines elements of agile and waterfall development. 

In agile-waterfall, the project is broken down into two phases: the waterfall phase and the agile phase. People use this method to develop the known and stable requirements, while the agile phase is used to develop the unknown or likely-to-change requirements.

The waterfall phase is typically more traditional, with a more rigid plan and less communication between team members. Whereas, the agile phase is typically more flexible, with more communication between team members and more frequent delivery of working software.

Here are some of the advantages of agile-waterfall:

  • Flexible Requirements
  • Balance
  • Included Traditional Approach

Despite the benefits, here are some of the disadvantages of agile-waterfall:

  • Take a lot of effort
  • Less Collaboration
  • Difficult Tracking

3.2. Kanban

Kanban is a visual system for managing work. It is a popular agile methodology that is used in software development, but it can be applied to any project where there is a need to visualise work and limit work-in-progress. 

Teams use Kanban boards to track a variety of types of work, including tasks, features, bugs and progress, and they can pull work from the board as they are ready to work on it. Development team also use it to track work at different levels, from an individual task to an entire project. They typically have three columns: To Do, In Progress, Done.

Here are some of the benefits of using Kanban:

  • Visualisation.
  • Limiting work-in-progress
  • Improving efficiency
  • Collaboration

Meanwhile, the drawbacks of using Kanban could be:

  • Requires discipline.
  • Can be difficult to implement
  • Not suitable for all projects

Lean Software Development (LSD) is a framework that defines the steps involved in the creation of software. It is a systematic approach to planning, designing, developing, testing, and deploying software. For that reason, large IT project often use LSD method. The goal of SDLC is to produce high-quality software that meets the needs of the users and stakeholders, as well as manage the project in a smooth manner.

The SDLC helps developers deliver software with the highest quality at the lowest cost. SDLC can help developers develop software in a well-structured way and maintain its quality by testing and validating user demands before releasing the software. It’s important for a software developer to have an intense knowledge of this software development process.

Benefits of using LSD: 

  • Improved quality
  • Increased customer satisfaction
  • Increased productivity

Here are some of the drawbacks of using lean software development:

3.6. Extreme Programming (XP)

Extreme Programming (XP) is an agile software development methodology that is based on the 5 key values: Communication, Simplicity, Feedback, Courage, Respect.

XP is a set of practices that support these values. Some of the key practices of XP include:

  • Pair programming: Two programmers work together at one computer, one driving and one observing. This helps to improve the quality of the code, as well as to catch errors early.
  • Continuous integration: The team integrates their code frequently, typically several times a day. This helps to identify and fix errors early and in time.
  • Refactoring: The team refactors their code regularly to improve its structure and readability. Consequently, this makes the code easier to understand, maintain, and change.
  • Test-driven development: The team writes unit tests before they write any code. This helps to ensure that the code works as expected.
  • Acceptance testing: The customer writes acceptance tests that define what the software should do. In this situation, these tests are used to verify that the software meets the customer\’s needs.

Here are some of the benefits of using XP:

  • High-quality software
  • Fast delivery
  • Flexibility
  • Teamwork

Here are some of the drawbacks of using XP:

  • Requires experienced team member
  • Can be difficult to implement
  • Not suitable for all projects

Scrumban is a hybrid methodology that combines elements of Scrum and Kanban. It is a good choice for projects where there is a need to deliver working software quickly and efficiently, but where there is also a need to be flexible and adaptable to change. Because of its combination feature, this method is based on 4 principles: Incremental delivery, Transparency, Collaboration and Continuous improvement. 

Some of the key practices of it include:

  • Sprints: Teams use sprints to deliver working software. Sprints typically last two weeks, but they can be shorter or longer depending on the project.
  • Kanban boards: Teams use Kanban boards to visualise their work. This helps to ensure that everyone is on the same page and that work is not being duplicated.
  • Daily standups: Teams hold daily standups to synchronise their work, as well as to identify any blockers.
  • Retrospectives: Teams hold retrospectives at the end of each sprint to reflect on the past sprint and to identify ways to improve.

Here are some of the benefits of using this methodolgy

  • Delivering working software quickly
  • Flexibility
  • Collaboration
  • Continuous improvement

Meanwhile, some of this method’s drawbacks are:

  • Requires experienced team members
  • Can be difficult to implement
  • Not suitable for all projects

Adaptive Software Development (ASD) is an agile software development methodology that is based on the following principles: Continuous adaptation, Collaboration, Iterative and incremental development, Testing.

ASD is a set of practices that support these principles. Some of the key practices of ASD includes: 

  • Planning: ASD teams plan their projects in an iterative and incremental fashion. This means that they plan for the next increment of the project after the previous increment is completed.
  • Communication: ASD teams communicate regularly with both the customer and stakeholders to ensure that everyone is on the same page.
  • Design: ASD teams design the software in an iterative and incremental fashion like Planning practice. This also means that they design the software for the next increment of the project after the previous increment is designed.
  • Development: ASD teams develop the software in an iterative and incremental fashion, so they also develop the software for the next increment of the project after the previous increment is developed.
  • Testing: ASD teams test the software continuously to ensure that it works as expected. In detail, they test the software for the next increment of the project after the previous increment is tested.

Here are some of the benefits of using ASD:

  • High-quality software
  • Customer satisfaction
  • Flexibility
  • Testing

Meanwhile, here are some of the drawbacks of using ASD

  • Requires experienced team members
  • Can be difficult to implement
  • Not suitable for all projects
