In the fast-paced world of software development, agility and adaptability are paramount. Agile development methodologies have revolutionized the way software is developed, tested, and released, ensuring that the end product is both high-quality and aligned with user needs. Nowadays, Agile software development outsourcing has become increasingly popular due to its package of benefits, enabling businesses to accomplish their projects faster without compromising on quality. In this article, we will explore the various types of agile software development methodologies that are commonly used today.

What Is the Agile Software Development Methodology?
The Agile software development method stands as a dynamic and collaborative strategy for crafting software, spotlighting efficiency, and creating superior products. It segments projects into digestible phases, fostering ongoing cooperation, adaptability, and enhancement at every stage of the development journey.
Agile places a premium on direct interaction over exhaustive documentation, functional software over elaborate planning, and engaging with customers over negotiating contracts. This approach is adept at navigating changes in requirements and priorities, ensuring it remains attuned to user expectations and shifts in the market landscape.
Central to Agile are practices like pair programming, test-driven development, daily stand-up meetings, sprint planning, and the execution of sprints – intense, brief cycles dedicated to accomplishing specific project objectives. These methodologies underpin the essence of Agile: Iterative development, where solutions are refined through the synergy of autonomous, multidisciplinary teams.
Agile is committed to the regular delivery of functional software, ranging from a few weeks to a couple of months, always with a bias towards shorter intervals. It motivates teams to sustain a steady workflow, aspire for design brilliance, and streamline processes to enhance productivity. A relentless focus on technical prowess and thoughtful design propels agility forward, as self-directed teams are inspired to introspect on their efficacy, making adjustments to continuously evolve and improve.
A List of All the Common Agile Methods
Under the broad Agile canopy, there are different methodologies that interpret Agile principles to meet diverse project specifications and team dynamics.
Scrum
Scrum is a framework that facilitates team collaboration on complex products. It structures development in cycles of work called sprints, which are iterations no longer than one month. Each sprint starts after a planning meeting where the whole team selects a set of tasks from the product backlog to deliver during the sprint. Daily stand-up meetings help keep momentum, and a sprint review and retrospective at the end aim to refine processes and products for the next sprint. This structure supports a disciplined project management style that insists on upfront, transparent communication among team members and stakeholders, making it easier to adapt to changes swiftly.
Kanban
Kanban is a visual system for managing tasks as it moves through a process. It visualizes both the process (the workflow) as well as the actual work being passed through that process. The goal of the Kanban method is to detect potential bottlenecks in your process and resolve them so work can flow through it cost-effectively at an optimal speed or throughput. Unlike Scrum, Kanban does not work with fixed iterations; the workflow is continuous. This makes Kanban very adaptable and perfect for teams that require flexibility and continuous delivery.
Extreme Programming (XP)
XP optimizes a software project in five essential ways: Communication, simplicity, feedback, respect, and courage. It advocates frequent “releases” in short cycles, which improves productivity and introduces checkpoints where new customer requirements can be adopted. Key practices include pair programming, test-driven development (TDD), continuous integration, and collective code ownership. These practices are intended to improve software quality and responsiveness to changing customer requirements.
Lean Software Development
By borrowing from the principles of lean manufacturing, this methodology focuses on creating more value for customers with fewer resources. The primary principles of a lean method cover amplifying learning, eliminating waste, deciding as late as possible, delivering as quickly as possible, empowering the development team, building integrity, and seeing the whole. By focusing on the efficiency of the development process and team morale, Lean encourages a more sustainable pace of development.
Crystal
Crystal methods recognize that each project might need a tailored set of policies, practices, and procedures to meet the project’s unique characteristics. It is less structured and prescriptive than other agile frameworks. The focus is on the people, their roles, skills, and working relationships within a development team. The crystal methodology promotes early, frequent delivery of working software, high user involvement, adaptability, and the removal of bureaucracy or distractions.
Feature-Driven Development (FDD)
This model-driven, short-iteration process emphasizes feature delivery. FDD blends multiple industry-recognized best practices into a cohesive combination. These practices are derived from a client-valued functionality perspective. Its ultimate purpose is to deliver tangible, working software repeatedly in a timely manner according to the Principles behind the Agile Manifesto.
Dynamic System Development Method (DSDM)
DSDM, or dynamic system development method, is an agile project delivery framework that uses a fixed cost, quality, and time approach, with the main goal of delivering business solutions on time and within budget. It incorporates elements such as active user involvement, empowered teams, and frequent delivery of products. The framework is built on eight principles that direct the team’s approach and attitude towards product development.
Adaptive Software Development (ASD)
ASD replaces the traditional cycle of planning, designing, building, and testing with a more fluid and iterative approach. It acknowledges that software development is a continuous discovery process involving concurrent component engineering and the inevitable evolution of requirements. The cycle of speculate-collaborate-learn encourages constant adaptation to the work and process based on learning and discoveries made during development.
Scrumban
Scrumban is defined as a management framework that emerges when teams employ Scrum as their chosen way of working and use Kanban as a way to view and improve their work. Scrumban provides the structure of Scrum with the flexibility and visualization of Kanban, making it suitable for teams that need the ability to prioritize and adapt on a regular basis.
Behavior-Driven Development (BDD)
BDD enhances the methodologies of TDD by applying the shared tools and processes across roles for a collaborative approach. It encourages teams to leverage conversation and definitive examples to standardize a shared understanding of how the software solution should behave. It focuses on obtaining a clear understanding of desired software behavior through discussion with stakeholders.
Extreme Project Management (XPM)
XPM addresses the needs of extremely fast-moving project environments. It is characterized by high speed, high change, and high uncertainty. XPM practices include flexible planning, modularizing tasks, rapid prototyping, and concurrent design and development. It is suited for projects where the scope and requirements are expected to change frequently.
Adaptive Project Framework (APF)
APF offers a highly flexible and adaptive project management approach, recognizing that the scope of a project is variable rather than fixed. It promotes a cycle of version scope, cycle plan, cycle build, client checkpoint, and post-version review to manage and adapt to the changing aspects of projects. This approach allows projects to respond effectively to evolving requirements, stakeholder needs, and market trends.
Each of these methodologies brings unique strengths to the table, and the choice among them would rely on the specific needs of the project, the team’s dynamics, and the stakeholders’ priorities.
