In today’s fast-paced software development world, agility is not just beneficial; it’s essential.
Agility is defined as the skill of moving with speed and ease.
The Agile Software Development Life Cycle (SDLC) model is a response to the traditional, rigid development methodologies that often resulted in products outdated before their release. By applying lean principles, the Agile SDLC model ensures that development is flexible, iterative, and continuously improving.
It focuses on customer collaboration, response to change, and delivering functional software in short, sustainable bursts of work called “Sprints.”

The graphic illustrates a typical Agile SDLC timeline, spanning 10 weeks and divided into five sprints. Each sprint encapsulates the essential phases of software development: Analysis, Design, Coding, and Testing. Here’s how it unfolds:
- Sprint 1: The team kicks off with an analysis of Feature-1, designs it, codes it, and performs tests, resulting in a deliverable piece of software at the end of the first two weeks.
- Sprint 2: Building on the momentum, the team moves on to Feature-2, iterating through the same phases while the previous feature is being reviewed and refined based on stakeholder feedback.
- Subsequent Sprints: This cycle continues, with each sprint bringing a new feature from conception to completion. With every iteration, the software becomes more robust, more closely aligned with user needs, and incrementally enriched with features.

What sets the Agile SDLC model apart is its commitment to continuous improvement. After each sprint, the team reviews the process and the product, making adjustments as needed. This iterative refinement is the essence of applying lean principles—cutting out inefficiencies and honing in on what truly adds value to the customer.
Also, a significant benefit of the Agile SDLC model is the frequent delivery of software. Unlike traditional models that aim for a single, monumental launch, Agile allows for regular releases of workable software, each potentially shippable and adding tangible value to the user.
Conclusion
The Agile SDLC model’s application of lean principles revolutionizes software development. It places the focus squarely on delivering customer value, reducing waste, and adapting to change. By doing so, it aligns perfectly with the modern business landscape, where the ability to pivot and evolve quickly is a competitive advantage.
