08 Jul Agile vs Waterfall Pros, Cons, and Key Differences
Once the plan is in place, the team follows the same pattern as traditional Waterfall but does it for each story. They do the analysis for one story, then all the design for one story, then all the coding and testing for one story. The work is broken up into chunks that benefit the development team.
Report on key metrics and get real-time visibility into work as it happens with roll-up reports, dashboards, and automated workflows built to keep your team connected and informed. If you don’t expect to deal with change, Waterfall is a straightforward, efficient process. The issues with Waterfall come when you have to accommodate changes. Waterfall projects usually include defined requirements in advance, whereas requirements are expected to change and evolve in Agile projects.
Waterfall vs. Agile: How To Choose the Right Methodology for Your Project
For instance, siloed organizational departments and lack of collaboration tools restrict the ability to be truly collaborative and Agile in practice. Organizations follow Agile for planning, but swiftly transition to “fast waterfall” sprints in implementation. The agility isn’t truly designed and embedded during the execution. Both Waterfall and Agile require organizations to follow certain operating principles—but the practice often departs from the principles. It is therefore important to understand what Agile and Waterfall mean and how they differ as you make your choice for an SDLC framework that best suits your development goals.
As a result, it’s a much more fluid form of project management. A software development project can take years to complete, and technology can change significantly during that time. Agile was developed as a flexible method that welcomes incorporating changes of direction even late in the process, as well as accounting for stakeholders’ feedback throughout the process. Scrum is a subset of Agile and one of the most popular process frameworks for implementing Agile. It is an iterative software development model used that leverages incremental processes included in a larger framework that use cross-functional teams to meet goals and adapt to changes.

The goal is to deliver value to the customer or user as quickly and often as possible. Thus larger projects are broken down into smaller pieces so that progress can be made during each Sprint. Agile and waterfall often represent an irreversible fork in the road for any initiative.
This approach allows for the flexibility of Agile while still providing the structure and planning of Waterfall. If management still needs more defined predictability , you may need to try managing expectations. In a traditional model, you have a predictable date of delivery, but in reality, no one is going to deliver a product by that date if it’s not complete. Management is always going to wait for the product to be complete, regardless of the original date set. In the Kanban model, the expectations need to be adjusted to focus on delivering the product when it’s ready and complete.
A Kanban board has the same column-based layout as a Scrum board, but it requires no upfront planning. You can start working and moving through the flow of features of agile methodology the Kanban board without having a structured plan. The Kanban board can be shared by multiple people and is persistent; you don’t need to reset the board.
- The budget for projects using the Waterfall methodology is generally fixed.
- However, in recent years, more and more project management software tools have created online Kanban boards.
- Agile and waterfall methodologies are contrasting development approaches.
- Agile processes cannot function without a high level of trust amongst team members and therefore create trust.
- As a result, Waterfall is leveraged to preserve a sequential process and maintain stability throughout stages of a project.
It’s not hard to see why when we observe the benefits that it can offer companies today. While there are a number of project management tools that can help teams track progress, IBM can also provide systems to enable developers to code in a more agile way. The waterfall project management approach entails a clearly defined sequence of execution with project phases that do not advance until a phase receives final approval.
The Kanban system will make sure that all tasks are completed as soon as possible, so a deadline is no longer necessary. There are no timebox constraints or planning, however once a team has optimized the flow of work and can get a sense of how long certain tasks take, there will be some level of predictability. When looking at Kanban vs Agile, it’s important to remember that Kanban is one flavor of Agile. It’s one of many frameworks used to implement Agile software development. Kanban was inspired by the Toyota Production System and Lean Manufacturing. In the 1940s, Toyota improved its engineering process by modeling it after how supermarkets stock shelves.
Overwhelmed by the popularity of agile, you might want to adopt agile and transform your waterfall organization into agile. When teams have clarity into the work getting done, there’s no telling how much more they can accomplish in the same amount of time.Try Smartsheet for free, today. Scrumban can look more like Scrum on the technical level, but at the cultural level, it will more closely resemble Kanban. Instead of big changes all at once, Scrumban encourages incremental changes. If your team is looking to migrate from Scrum to Kanban, Scrumban can provide a gentle transition.
Here are a few examples of projects we’ve done in Agile, along with others we’ve done in Waterfall. We also provide links to corresponding in-depth case studies for those who want to learn more. In complex Agile-Waterfall Hybrid use cases, teams need adequate tooling to maintain transparency, traceability, and accurate project management. Tooling is a crucial question as relying on insufficient tools could break the success of an otherwise sound implementation of Agile-Waterfall Hybrid model. Waterfall methodologies are more rigid, but are often easier to coordinate between teams.
By collaborating with customers, Agile teams can prioritize features that focus on customer needs. When those needs change, teams can take an Agile approach and shift to a different project. Working with SDLC models often includes additional software to keep track of planning, tasks and more. So it’s possible to find tools designed to support the waterfall methodology’s specific workflow, for example.
Once you choose one path, it’s quite challenging to change course for that project, so it’s not a decision to take lightly. That’s not to say that Agile and waterfall can’t coexist in the same organization, but for a particular project, it’s usually a “one-or-the-other” inflection point. Learn more on how your team can build your next development project within an agile environment. Workflow is about bringing structure and scale to that process. Agile processes cannot function without a high level of trust amongst team members and therefore create trust.
Dynamic Systems Development Method (DSDM)
Scoff was designed to serve local restaurants, whose menus changed regularly. Net Solutions used Waterfall to develop Scoff’s MVP, and you can read about the full story here. Edplace is a home-learning app for children, and the company hired Net Solutions to design and build an app that helps parents monitor their children’s performance. This led to a long-term engagement, where Net Solutions used Agile to continually improve Edplace’s digital products. For example, if you wanted to build a custom house from scratch, you’d first meet with an architect who would listen to your input and draw up blueprints.
Which is better, Agile or Waterfall?
Your ultimate choice between these two methodologies depends much on several factors. It guarantees that the quality of the development is clearly maintained. This is the result of more frequent involvement of the customer.
To create a Scrum board, the Scrum team must first create sprints, assign points to user stories, and plan which stories go into which sprint. Then, the Scrum board visualizes the sprint, showing which stories are in plan mode or work mode. The Scrum board is reset between each sprint and is owned by one specific team. Make your Scrum board digitally or physically, whichever works best for your team. Another potential drawback of pure Waterfall development is the possibility that the customer will be dissatisfied with their delivered software product. As all deliverables are based upon documented requirements, a customer may not see what will be delivered until it’s almost finished.
If you’re working on a distributed team, spend time communicating in ways that involve face-to-face communication like Zoom calls. The article below covers the common scenarios when Hybrid can be used. I also talk about why this can be a good approach in certain situations, and how the Hybrid method should be used in those cases. Many organizations struggle to manage their vast collection of AWS accounts, but Control Tower can help.
When You Should Use Kanban and When to Use Agile
Agile methodology uses an iterative process where all the teams and collaborate and client provides feedback throughout the entire process of developing a new software product. And, if you want your project team to get started right away with a new method, Kanban is easier to understand. There is no training required and it can be used on top of any existing process.
