Understanding the Software Development Life Cycle (SDLC)

The software development life cycle (SDLC) is a framework that defines each stage of development. It ensures consistency, efficiency, and high-quality results.

Phases of the Software Development Life Cycle

Requirement Analysis – Collect business and customer needs.
System Design – Define architecture and user interfaces.
Coding – Write and apply logic using clean code.
Testing – Verify functionality.
Deployment – Publish the software to users.
Maintenance – Implement updates, bug fixes, and enhancements.

What is Adaptive Software Development?

Adaptive Software Development (ASD) emphasises flexibility, high-frequency iteration, and teamwork. It’s particularly good for rapidly changing sectors like fintech, healthtech, and e-commerce.

Key Principles of ASD

Speculation: Planning, keeping uncertainty in mind.
Collaboration: Testers, developers, and clients are a single team.
Learning: Feedback and iteration-based improvements.

Agile Software Development Methodology

The Agile software development process has revolutionised the way teams deliver projects. In contrast to the Waterfall model, which is strict, Agile encourages continuous delivery, adaptability, and feedback from customers.

Agile Process for Software Development

Sprint-based development
Communication through daily stand-ups
Incremental releases
Concurrent client engagement

As stated by Atlassian Agile Guide, Agile allows for quicker output and less risk.
✅ At Nextr, our team uses Agile methodology in software development to implement prototypes rapidly with a flexibility to adjust to client requirements.

Custom Software Development for Businesses

Each business has different requirements. Off-the-shelf products may not be sufficient in all cases, which is where custom software development comes into play.

Advantages of Custom Software

Tailored to your specific needs
Safer than generic applications
Scales with your business growth
Comes with a competitive advantage

Example: An e-commerce business might need features such as AI-powered product suggestions, which can’t be offered by generic platforms.
