Software development methodologies are the structured approaches a team uses to plan, build, test, and ship software. This guide compares nine of them: Waterfall, Agile, Scrum, Kanban, Extreme Programming (XP), Lean, DevOps, Rapid Application Development (RAD), and Spiral. Choosing between them depends on five factors: requirement stability, regulatory load, stakeholder availability, team size and seniority, and contract structure.<\/p>\n

What is a software development methodology?<\/h2>\n

A software development methodology is a systematic approach that defines how a team plans, builds, tests, and ships software. It fixes the order of work, how requirements are handled, how often the team releases, and who decides when something changes.<\/p>\n

A methodology is not the same as a model. Models such as Waterfall and Spiral set how a project moves through the SDLC phases, and our guide to software development models<\/a> covers them in depth.<\/p>\n

How do a methodology, a framework, and a model differ?<\/h3>\n

A methodology is a philosophy of work, such as Agile. A framework is a prescribed structure that applies it. A model sets how the project moves through the software development life cycle<\/a>, and the phases are the same whichever one you pick.<\/p>\n

Some approaches, such as Waterfall and Spiral, are models that people also call methodologies. They appear here in short form for that reason. We use “methodology” loosely below because that is how the industry talks.<\/p>\n

What are the main types of software methodologies?<\/h2>\n

The nine methodologies fall into three families. Plan-driven methodologies are Waterfall and Spiral, Agile methodologies are Agile, Scrum, Kanban, XP, and Lean, and delivery-focused methodologies are DevOps and RAD. The comparison below is TekRevol’s judgment.<\/p>\n

What are the plan-driven methodologies?<\/h2>\n

Plan-driven methodologies fix the plan early and manage change through gates. They suit projects where a late change costs far more than upfront planning.<\/p>\n

Waterfall<\/h3>\n

Waterfall is a sequential methodology in which each phase of SDLC<\/a> finishes before the next one begins. It fits fixed-scope, regulated builds where an auditor will ask for traceability from requirement to test case, but it breaks when requirements move, because feedback arrives last.<\/p>\n

Spiral<\/h3>\n

In TekRevol’s summary, Spiral combines iterative development with formal risk analysis, so each loop tackles the biggest remaining risk first. It is built for large, expensive projects where failure would be catastrophic. For a straightforward web platform, it is disproportionate.<\/p>\n

What are the Agile methodologies?<\/h2>\n

Agile methodologies ship small, gather real feedback, and treat changing needs as normal. Agile is the umbrella, and Scrum, Kanban, XP, and Lean are the ways teams apply it.<\/p>\n

Agile<\/h3>\n

Agile<\/a> is a set of values from the 2001 Agile Manifesto, including working software over comprehensive documentation and responding to change over following a plan. The Manifesto sets four values and twelve principles but never specifies sprint length or who runs standups. That is why Agile heads a family of methodologies and does not stand alone.<\/p>\n
