When it comes to software development, you’ll often hear people argue about whether agile or waterfall methodologies are more effective. Agile relies on quick adaptation to gather data and pushing out product features little by little, whereas waterfall delivers a very specific output after a long, uninterrupted period of careful planning. While these might seem like two opposing methods, the truth is that very few development processes work exclusively with one or the other.
For instance, a client might want to check-in on your progress throughout a waterfall project or stakeholders could ask what the completed results of an agile project will be. Eitherway, in most cases, you need a mix of both methods to work practically in a real business setup. To accommodate for this, you can implement WAgile — a hybrid method that combines the principles of agile and waterfall.
Keep reading to learn more about the WAgile method, including its strengths and weaknesses, when to apply it, and best practices for its implementation.
What is WAgile?
WAgile is a hybrid project management methodology that integrates the structured, sequential phases of waterfall with the iterative, flexible practices of agile. The term “WAgile” is derived from blending waterfall and agile together.
WAgile leverages the strengths of both methodologies to create a more adaptable and efficient project management process.
What is the waterfall methodology?
To understand WAgile, you first need to have a sense of how the two parts work on their own. The basis of waterfall includes:
Summary
- Sequential phases — Projects are divided into distinct phases such as requirements gathering, design, implementation, testing, and deployment
- Predictability — Each phase must be completed before moving on to the next, providing a clear roadmap and timeline. The outcome of each phase is defined well in advance and any deviation will be seen as a bug or poor craftsmanship
- Documentation — Extensive documentation is created at each stage, ensuring thorough planning and clarity. This will also allow the client to understand the end product better and, in the future, modify it with potentially a different development team
Strengths
- Clear structure — The defined phases provide a clear roadmap and timeline, making it easy to manage and understand what will be delivered by the team
- Predictability — Detailed planning and documentation ensures that all requirements are known upfront, reducing uncertainty
- Ease of reporting — The defined stages and deliverables make it easier to manage large, complex projects and know exactly whether the development is going well
- Compliance — The waterfall framework is well suited for projects, clients, and industries with strict regulatory requirements due to its structured approach
Weaknesses
- Inflexibility — Once a phase is completed, it’s difficult to go back and make changes. It basically means restarting or creating a parallel thread of the waterfall process
- Delayed feedback — Feedback is typically received only at the end of each phase, which can lead to issues being discovered late in the project. A lot of initial assumptions might simply be false
- Risk of obsolescence — Long development cycles can result in the final product being outdated by the time it’s delivered.
- Limited customer involvement — Less frequent interaction with stakeholders can lead to a product that doesn’t fully meet customer needs
What is the agile methodology?
Unlike waterfall, agile delivers incremental product releases that you adapt to customer feedback. The method includes:
Summary
- Iterative development — With agile, you divide work into small, manageable increments called sprints. This allows for regular reassessment and adaptation
- Flexibility — Agile embraces changes even late in the project. It relies on continuous improvement and responsiveness to feedback
- Collaboration — In this approach, you constantly communicate with cross-functional teams and stakeholders through regular meetings and updates. This helps ensure the optimal value of the product and, by design, should provide a better product in the end
Strengths
- Flexibility and adaptability — Agile allows for changes even late in the project, making it highly adaptable to new information and requirements. You can pivot the product at any time for good reason and it is easy by design
- Customer focus — Continuous feedback from stakeholders ensures that the product meets customer needs. This could be direct information from a client, the user base, or both
- Rapid delivery — Iterative development allows for quicker delivery of functional components. It also allows you to test ideas and easily remove failed experiments
Weaknesses
- Less predictability — The iterative nature can make it difficult to predict timelines and costs accurately. Generally, you shouldn’t aim for a date, but for a product goal
- Scope uncertainty — Flexibility can lead to scope creep if not managed properly
The WAgile methodology
When you combine waterfall and agile, you get the best of both worlds. This enables:
Summary
- Hybrid approach — WAgile combines the predictability and structure of waterfall with the flexibility and iterative nature of agile
- Phased iterations — Projects may start with a waterfall approach for initial planning and requirements gathering, then transition to agile for development and testing. This allows for a solid starting foundation with some flexibility later on
- Risk management — By incorporating agile practices, WAgile allows for early detection and mitigation of risks through continuous feedback and iteration. It makes it easier to achieve a result that the users and clients will appreciate
- Improved communication — Regular agile meetings (e.g., daily stand-ups, sprint reviews) enhance communication and collaboration among team members as well as progress transparency with the clients/users
- Flexible planning — Initial project planning and requirements gathering may follow waterfall, but subsequent development and testing phases adopt agile’s iterative approach
- Feedback loops — Agile’s emphasis on continuous feedback and iteration integrates into the waterfall framework, allowing for adjustments and improvements throughout the development process
In comparison to its “parents,” WAgile exhibits the following:
Strengths
- Realistic application — WAgile combines the structured planning of waterfall with the iterative development of agile, which is basically how most companies run their processes anyway
- Best of both worlds — The method leverages the strengths of both methodologies, making it suitable for projects that require both detailed planning and flexibility
- Risk management — It allows for early detection and mitigation of risks through continuous feedback and iteration
Weaknesses
- Complexity — Integrating two methodologies can be complex and may require significant effort to manage effectively
- Potential conflicts — Differences in the philosophies between agile and waterfall can lead to conflicts and confusion, if not outright opposition, within the team
- Resource intensive — You may need more resources to manage the hybrid approach effectively on top of the waterfall’s planning and documentation steps
When to apply WAgile
Some projects operate better in a pure agile environment (new startup), and some perform better using waterfall (developing drivers for a new piece of hardware). Given that, where would Wagile be a good fit? These tend to be the best use cases:
Complex projects with varying requirements
A large-scale software development project with multiple phases and diverse requirements can benefit from this approach. Initial planning and design can follow waterfall, while development and testing phases adopt agile practices to handle changing requirements and feedback. As a result, you allow the high-level outcomes to be defined and documented early on, and then the details to emerge on the way via agile.
Transitioning to a new methodology
An organization transitioning from waterfall to agile can use WAgile to gradually introduce agile practices. This allows teams to adapt to the new methodology without a hard cutover, reducing resistance and ensuring a smoother transition. By doing so, you avoid a band-aid approach.
Regulatory or contractual requirements
If you have a project with strict regulatory or contractual requirements, use WAgile to ensure compliance while maintaining flexibility. Waterfall helps with the documentation and compliance phases, while agile can handle development and day-to-day operations. It can also facilitate shorter phases (use sprints for that) to ensure the client that the project is going according to plan.
How to implement WAgile
Now that you have a sense of WAgile, you can implement it into your projects with the following steps:
- Evaluate your company/product requirements — As you saw earlier in the article, WAgile is a blend of agile and waterfall. Determine which aspects of each method you need to customize your WAgile approach to your specific use case
- Define objectives — Clearly outline the goals and objectives of implementing WAgile, including your expected benefits and key performance indicators to ensure the framework works as intended
- Determine processes and roles — In this step, clearly define roles and responsibilities within the team, ensuring that everyone understands their part in the WAgile
- Get support — With all ready on paper, engage stakeholders to ensure their buy-in and support. This includes project sponsors, directors, and anyone who needs to sign off on the change
- Announce the implementation — Communicate the benefits and challenges of Wagile to all stakeholders, setting realistic expectations
- Organize training — Present your plan and set-up development sessions to ensure everyone knows how to use WAgile
Best practices for ensuring successful adoption
When it comes to WAgile, try to use these best practices to ensure a successful adoption:
- Start small — Begin with small, low-risk projects to test the WAgile approach and refine processes before scaling up
- Gather strong leadership support — When making any announcements, make sure the messaging comes from your management team. Your team will be more apt to buy-in when they see it has executive weight
- Introduce WAgile ambassadors — Name a few ambassadors for the new process, so they can promote it inside the company and answer any questions during the project runs
- Be open for feedback — Make it easy to report any issues and concerns with your WAgile implementation and react to them swiftly. You may have missed a few spots in the preparation phase and with the help of others, you can fix them quickly
Conclusion
While the name WAgile may sound outlandish, you probably have already used the method without even knowing. In a mature company, an agile project always needs a plan, expectation setting, and a deadline. On the other hand, no waterfall project works without any user feedback.
WAgile represents a whole spectrum of project management approaches that bridge the gap between waterfall and agile. This enables you to customize the method to your own use case so that you don’t find yourself limited by out of the box solutions. Try it out for yourself today!
