Various methodologies have been utilized throughout the history of computer software and process system development. These methodologies design, manage, and control the development process using diverse frameworks. The software development lifecycle (SDLC) involves planning, analysis, design, and implementation phases.
Scrum and Waterfall are both software development methodologies. A development methodology provides a basic conceptual structure for project completion. The main difference between the two methodologies is their focus. Scrum emphasizes value and shorter iterations. However, Waterfall focuses on schedules, estimated costs, and planning. This blog will explore Scrum vs. Waterfall methodologies so you can determine which suits your project best.
With Scrum, teams can adjust to changes during project development. This is because Scrum uses sprints (short work periods). A sprint can be two weeks long. It consists of planning, designing, building, and testing stages. The Waterfall method, instead, follows a strict order.
Scrum is a management framework utilized by teams to self-organize and collaborate. It includes specific meetings, tools, and roles to ease effective project delivery. Scrum practices enable teams to manage themselves autonomously. This is like a rugby team preparing for a significant match. The match preparation happens as they gain insights from past experiences and adapt to changes.
Scrum is not from a construction and manufacturing background. Instead, it considers the needs of the software world. You cannot thoroughly plan and document software products before the development phase. This way, you can avoid planning paralysis. Within a month of development, you can give the stakeholders a usable form of the software. As the needs of the stakeholders become clearer, the product can evolve.
Agile is an iterative and incremental development methodology. Scrum is a specific implementation of the Agile methodology that delivers timely gradual changes. Ken Schwaber and Jeff Sutherland, co-signers of the Agile Manifesto, developed Scrum. It embraces Agile ideals by avoiding long-term planning. As a result, it delivers usable features to clients every 2-4 weeks. Stakeholders give feedback throughout development. So, it provides daily opportunities for developers to adjust their short-term plans.
The Scrum guide states, “Successful use of Scrum depends on people becoming more proficient in living these five values.” The five core Scrum values are as follows:
Focus
Openness
Commitment
Courage
Respect
Waterfall models involve extensive upfront planning, documentation, and customer negotiations to establish precise specifications. The Waterfall method is well-suited for manufacturing and construction operations. These operations thrive on meticulous planning. Moreover, Waterfall projects require changes made in earlier development phases. It can be time-consuming as reviews happen at the end. Therefore, you have to restart from the beginning if issues arise. Documentation is primarily done during the initial requirement phase. You complete each phase and process sequentially, one at a time. This could have severe consequences for the current lifecycle phase. The Waterfall model consists of the following stages of development:
Requirements gathering
Analysis and design
The building or implementation phase
Testing and validation
Deployment and delivery
Ongoing maintenance
An example of a Waterfall project would be building a house. The floor plan for a mansion can only change sometimes. Imagine changing the house map after the foundation has been laid. For this kind of application, you can follow the isolated, unidirectional phases of the Waterfall model.
Here’s a side-by-side comparison of the Scrum vs. Waterfall SDLC:
Waterfall SDLC | Scrum SDLC |
Product requirements are clear | Product requirements are adaptive |
Defined schedule and cost estimates | Estimates are determined based on the value of features |
Stakeholders are only involved near the end of the project | Stakeholders involved in each phase |
Work is divided into phases, and the team works closely | Work is divided into teams that work in sprints |
Reports progress by activity and stage gateways | Reports progress by delivering valued features every two weeks |
Bound by a tight deadline | No tight deadline |
The Waterfall approach suits banking, government, and manufacturing sector projects. These projects should have the following qualities:
Well-defined feature requirements
Very few chances of changes
Repeatable processes
Emphasizes sign-offs for each stage
Teams with more than ten people
The Scrum method is more beneficial for feature-driven development. Ideally, projects that adopt Scrum should have the following attributes:
Smaller teams that can self-manage
Complex with changing requirements
Low-level details are not defined
Stakeholders who want to be involved in the development process
A product that needs to be delivered in short sprints rather than months of waiting
If working faster is a priority for you, you can try Scrum. The Waterfall approach is more suitable for a linear workflow.
How can an organization take advantage of the flexibility of Scrum while still using the Waterfall method? There is potential for creating a hybrid approach to do this. The Waterfall method can be utilized during the requirements gathering and design phase. During the implementation phase, Scrum can be used for the iterations.
Large organizations need help to transition from the traditional Waterfall model. This combination can help them switch to the Agile method. Each team has different preferences for project management. This can make sure everyone is comfortable with the transition. Clients and finance professionals would prefer Water-Scrum-Fall (wagile) because it allows for feasibility check-ins.
The shift to remote and hybrid work has changed how teams use both methodologies. Stand-ups, sprint reviews, and retrospectives in Scrum now often happen asynchronously across time zones, supported by collaboration tools like Slack, Jira, and Miro. Waterfall teams rely heavily on digital project-tracking platforms to manage documentation, milestones, and dependencies.
Key adaptations include:
Async Scrum rituals to accommodate distributed teams.
Global milestone planning for Waterfall projects across geographies.
Increased focus on documentation and visibility to ensure alignment without in-person meetings.
Modern project management tools have blurred the lines between methodologies, making them more adaptable and team-friendly in remote settings.
Choosing the right methodology isn’t about picking a “winner.” Instead, it’s about matching the approach to your team, project, and context. Here’s a quick guide:
Choose Scrum if requirements are unclear, user feedback is crucial, and the project demands continuous improvement.
Choose Waterfall if requirements are fixed, regulatory compliance is strict, or the project has a clearly defined end state.
Choose Hybrid if you need the predictability of Waterfall planning but the flexibility of Agile delivery.
Think of methodologies as tools, and successful teams know how to use more than one.
Project management is evolving again with the rise of AI-driven planning tools and predictive analytics. These technologies help teams forecast delivery risks, auto-generate sprint backlogs, and even recommend when a project should shift from Waterfall to Agile practices.
Modern platforms integrate machine learning with project telemetry, helping managers spot bottlenecks and adjust workflows dynamically. As these tools mature, the line between Scrum, Waterfall, and hybrid approaches will continue to blur, and adaptability will become the most valuable project management skill.
Delivering value to your stakeholders is of the utmost importance. Scrum and Waterfall have different applications and offer different benefits. Scrum works better for complex projects, while Waterfall is preferred for smaller ones. Make sure you choose the most feasible framework to suit the schedule and budget of the project. You must study each method thoroughly before making the final decision for your team.
