The dichotomy of traditional project management methodologies, namely Waterfall and Agile, has long dominated discourses in the tech industry. While some favor the structured predictability of Waterfall, others prefer the dynamic flexibility offered by Agile. 

However, this binary understanding from a management perspective overlooks a vital truth: the most effective methodologies are not rigid doctrines but adaptive strategies. At Propel, we recognize the inherent value in blending these approaches to craft tailored technology solutions.  

The recent HBR article “It’s Time to End the Battle Between Waterfall and Agile” by Antonio Nieto-Rodriguez, resonated with our blended project management strategy. We, too, recognize the inherent value in blending these approaches to craft innovative and tailored technology solutions that companies love to use. 

We realize that the key to a successful project outcome lies in understanding the core nature of the problem and opting for a balanced mix of the meticulous planning of Waterfall with the responsive agility of Agile.  

This article aims to explore how Propel's use of hybrid methodology overcomes traditional boundaries, demonstrating not only its feasibility but also its superiority in navigating the complexities of modern project management.  

Understanding Waterfall and Agile 

Waterfall 

The Waterfall model is championed for its predictability and comprehensive documentation. Signature projects such as Crossrail and the Burj Khalifa have demonstrated this method's capacity for clear and defined planning as key factors for success.  

While its structured progression provides clarity and predictability, it reveals its limitations when projects expand beyond their initial parameters or when objectives lack initial clarity, as evidenced by the delayed issue resolution in initiatives like the Myki ticketing system and the National Broadband Network. 

These limitations are also pronounced when inflexible planning leads to late-stage discoveries of issues, a characteristic of the Waterfall method's traditional end-stage testing. As a consequence, projects like the U.S. government’s HealthCare.gov, ended up costing over $2 billion, resulting in a flawed launch, leading to public and political outroar, and expensive time and resource-consuming rework. 

Agile 

Conversely, the more adaptive approach of the Agile methodology, calls for an iterative process and allows for robust client engagement, which has been instrumental in the ascent of tech giants like Google and Amazon. The concept of incremental development is central to Agile methodology where projects are deconstructed into manageable segments. 

This adaptability inherent in Agile methodology is invaluable, as Spotify’s evolution demonstrates. The music-streaming giant's Agile response to changing market demands and consumer behavior allowed it to expand beyond a simple music streaming platform to offering podcasts, videos, and personalized playlists. 

However, the very flexibility that defines Agile's strengths can also introduce challenges. Aside from sparse documentation, without a dedicated and engaged team, Agile's iterative nature can lead to confusion, misalignment, or even project derailment, if there's a failure to prioritize tasks effectively or maintain consistent communication. 

This is evident in large-scale endeavors, demanding steadfast predictability and clear timelines, like the One World Trade Center, where the Waterfall methodology’s emphasis on methodical planning and consistent timelines are not just beneficial but crucial. 

Hybrid Methodology  

As a testament to the industry's innovation, the evolution of project management has given rise to hybrid methodologies. 

The hybrid framework embodies the rigor of Waterfall's structured planning and the versatility of Agile's iterative nature. Companies like Philips have harnessed this dual approach in their digital transformation, blending Agile's adaptability with the systematic architecture of Waterfall. 

DBS Bank and telecommunications leader British Telecom (BT) also exemplify this trend, with DBS orchestrating phased infrastructure renovations alongside iterative customer-centric services. BT's deployment of its 5G network, too, leverages Agile for digital services, ensuring that customer feedback shapes the product's evolution, contributing to its significant annual revenues. 

The Hybrid approach can allow opportunities for flexibility and mitigating risks while navigating the complexities of delivering innovation. Consider the case of Tesla's approach to developing the Model 3. It merges Agile's responsiveness of using over-the-air software updates post-production for swift issue resolution and continuous enhancement of vehicle features, with Waterfall's rigorous planning and risk assessment methods for the construction of the Gigafactory, where the vehicle’s batteries are to be produced.  

The Propel Way: Hybrid Methodology in Action  

Propel aligns with HBR’s perspective, advocating a hybrid methodology that leverages the strengths of both Waterfall and Agile to circumvent their respective limitations.  

“Maslow's observation that 'If all you have is a hammer, everything looks like a nail,' rings particularly true in the world of problem-solving. But at Propel, we can't afford to have such a fixed mindset when we build custom solutions. We understand that methodology should be tailored based on the problem and business need, a perspective that comes with delivery maturity. Leveraging data from our project management practices helps us continuously improve our processes and embody the essence of a hybrid methodology.”

As a services company, our most valuable resource is time. Propel’s commitment to the hybrid methodology is born out of extensive experience, dealing with project work and building customized software solutions for various industries, predominantly for professional services, accounting and taxation, healthcare, government, logistics, telecommunications, automotive, insurance, retail, and media, sports, and entertainment, among others. 

The hybrid methodology, then, is not merely a compromise between Waterfall and Agile; it is a comprehensive approach that utilizes the best of both strategies, complementing each other’s weaknesses and augmenting their strengths.  

For example, the Waterfall approach is strengthened by its structured documentation, which ensures that every phase of the project is meticulously outlined and understood by all stakeholders. However, traditional Waterfall tends to lack in areas such as continuous planning, retrospection, and risk assessments — aspects where Agile excels. Conversely, in scenarios where project requirements are fluid and likely to evolve, necessitating frequent reassessment and ongoing client engagement, the Agile methodology proves to be effective. Yet, Agile often does not prioritize comprehensive documentation in the same way Waterfall does, typically favouring user stories and other forms of lightweight documentation. 

In the hybrid model, the initial deployment of Waterfall helps provide a framework of structured planning, clear deadlines, and documentation under time constraints, while the Agile methodology fosters an environment for iterative refinement, continuous feedback, and adaptability. 

At Propel, we see documentation not just as a record of what we do, but as a reflection of our strategic thinking. This meticulous approach to documentation ensures that our solutions are not only effective but also sustainable. It enables us to blend Waterfall's structured planning and clarity with Agile's flexibility and client-centric approach, providing solutions that are well-thought-out and adaptable to the evolving needs of our projects and clients. 

In this skilful integration of Waterfall and Agile methodologies at Propel, we find a unique strength: the ability to adapt to diverse project requirements and stakeholder preferences.  

The hybrid approach allows for incremental enhancements over time without sacrificing the initial groundwork laid out in the Waterfall phase, fostering a project environment that is both flexible and predictable, and equipping us to deliver outcomes that are both reliable and resilient. 

It enables collaboration and alignment between teams accustomed to different project management methodologies, fostering a cohesive working environment. 

For our digital transformation initiatives, we implement rigorous Waterfall planning for foundational elements while embracing Agile’s flexibility for customer-facing features. The hybrid approach takes into consideration a variety of factors and can be customized to fit the needs of the project, team, and end-users.  

In an era where change is the only constant, the Propel way is a commitment to excellence, ensuring that each solution we craft is a response to not just today's challenges, but a step towards tomorrow's innovations.
