When it comes to producing high-quality software, subscribing to a Software Development Life Cycle (SDLC) methodology is a must. But, with so many approaches to choose from, figuring out which is right for your business can be a challenge.

To help you see which SDLC model best aligns with your goals, here is an overview of the most common and effective approaches.


The Agile methodology is incredibly popular among software developers. It provides a level of flexibility that wasn’t available in the approaches of the past and focuses on making incremental changes to each iteration.

A benefit of Agile is that small portions of the software become functional throughout the process, so you can begin using them at earlier stages. This allows priority features to be addressed more quickly and makes it easier to acquire feedback to make improvements to the overall design.


Inspired by manufacturing processes, the Lean approach focuses on seven primary principles of avoiding waste, increasing learning, later decision-making, fast delivery, team empowerment, built-in integrity, and visualizing the whole.

Teams focus solely on what must be addressed at that specific moment, eliminating multitasking from the process. Developers also work to reduce waste at every stage, accelerating project development as much as possible.


A purely iterative approach to SDLC involves starting with a smaller set of known requirements, creating a solution based on those needs, then identifying new requirements to keep the project moving forward. Each iteration is fully functional, allowing it to be used as needed, and the process of completing a stage and identifying requirements continues until the entire project is complete.

While having a usable solution at each step is beneficial, the approach can require a significant amount of resources to be dedicated to the project.


The Spiral model uses a similar approach to the Iterative methodology, focusing on four primary phases (planning, risk analysis, developing, and evaluation) that are repeated until the project is complete. It is best suited for larger projects that involve a substantial amount of customization.

A benefit is the high amount of feedback that can be gathered throughout the project, making it easier to make adjustments early in the process. Plus, it focuses on risk management, which not all other models examine as closely.


In the grander sense, DevOps is relatively new when compared to other SDLC approaches. It incorporates segments from Agile and Lean but also encourages more cross-departmental collaboration.

Developers work closely with Operations teams to facilitate innovation and ensure that functional requirements are properly addressed. It also embraces continuous feedback to develop improvements as well as automation to support overall development.

Which SDLC methodology is right for you is predominately based on your goals and preferences, so none of the above are inherently better or worse than the other. But, your approach is only one part of a project’s success, you also need skilled staff members to ensure your vision is ultimately realized.
