Development of Agile Methodology
The roots of Agile delve into the dynamic and collaborative practices of the late 20th century. The 1970s and 1980s witnessed the emergence of iterative development practices, laying the groundwork for methodologies like Scrum, Extreme Programming (XP), and Feature-Driven Development (FDD). These methodologies were precursors, each contributing distinctive approaches to project execution. However, it was the pivotal moment in 2001, marked by the formulation of the Agile Manifesto, that unified these principles under a common umbrella. This manifesto underscored the values of flexibility, collaboration, and customer satisfaction as the guiding lights for Agile methodologies. In includes the following four principles, or key values:
- Individuals and interactions over processes and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
Variations of Agile Methodologies
There are now many different variations of Agile, each with their own focus points or advantages, evolved out of different needs. This allows us to find a method that is especially well suited for most tasks at hand, especially in a technological environment.
Scrum:

Lean Development:
Originating from lean manufacturing principles, Lean Development emphasizes simplicity and minimalism to achieve extreme efficiency. Complex tasks undergo deconstruction into simple components, efficiently handled by specialized team members. Success in Lean Development hinges on a robust developmental system to ensure effective execution.
Adaptive Software Development (ASD):
ASD stands out for its commitment to adaptation and change throughout the development process. Acknowledging the inevitability of emerging issues, ASD cultivates a culture of continuous learning and change, promoting collaboration and efficient problem-solving among team members.
Dynamic Systems Development Method (DSDM):
DSDM uniquely focuses on the business aspects of software development, emphasizing rapid product delivery through structured sprints. In line with agile principles, DSDM plans for continual software refinement, aiming to enhance both customer satisfaction and development efficiency by prioritizing business principles over traditional software development approaches.
Relationship with Other Methodologies
Agile and Waterfall:
The dichotomy between Agile and Waterfall lies in their respective project flows. Waterfall adheres to a sequential approach, while Agile embraces an iterative, adaptable stance throughout development. Recognizing the strengths of both, organizations often opt for a hybrid model known as Wagile. This hybrid approach enables structured planning while accommodating essential flexibility, finding a delicate balance between predictability and adaptability.
Agile and Lean:
The common ground between Agile and Lean methodologies lies in their shared principles of minimizing waste, optimizing efficiency, and prioritizing customer value. Organizations, recognizing the synergies between the two, often integrate Lean and Agile practices. This integration provides a comprehensive approach to project management and process improvement, aligning with the overarching goal of delivering maximum value to the customer.
Usefulness for SMEs
