The Pros and Cons of Waterfall Project Management

Waterfall project management is a popular and widely adopted method of managing projects. It involves establishing an order in which tasks must be completed before the next task can begin, with each phase having predetermined inputs and outputs. This type of methodology has been used on large-scale projects for decades, but it may not be right for every situation.

In this article, we will discuss some of the pros and cons of waterfall project management to help you decide if it is suitable for your project needs.

We will take a look at how waterfall methodology works, its advantages and disadvantages, as well as alternative methods that might be better suited to certain types of projects.

By understanding all these aspects, you can make an informed decision about whether or not waterfall project management is appropriate for your particular case.

A Brief History of Waterfall Project Management

The concept of waterfall project management has been around for centuries, with its roots in the industrial revolution. It emerged as a response to the need for efficient and effective ways to manage complex projects.

The name itself was coined by Dr. Winston W. Royce in 1970, who wrote a paper detailing the approach he felt should be used when managing large-scale projects. In this paper, Dr. Royce outlined five steps or phases which must be completed before any project can move onto the next phase of development - these are initiation/planning, design/development, testing and integration/deployment, and finally closure/maintenance.

This method is based on linear progressions and each step depends entirely upon the completion of the preceding one; thus making it an ideal way to manage highly structured projects that require careful planning from start to finish.

The Pros of Waterfall Project Management

Detailed Planning and Documentation

One of the great advantages of Waterfall is that it requires detailed planning and documentation in order to succeed. This means that any changes or improvements must be thoroughly thought out beforehand, meaning there’s less risk of costly mistakes being made during the project.

Also, because everything is documented throughout the process, it makes future projects much easier to plan and execute as you can refer back to past successes and failures for guidance.

The Cons of Waterfall Project Management: Less flexibility with change requests. Since a lot of time needs to be put into planning and documenting before executing a project using the Waterfall methodology, there’s less room for flexibility when it comes to making changes during the course of a project.

It also takes longer than other methodologies such as Agile which allows teams to respond quickly when needed.

Clear Project Objectives and Milestones

The waterfall methodology is based on a sequential approach. This means that each phase of the project has clearly defined objectives and milestones.

It allows the team to easily track progress, identify any problems or risks early, and adjust course as needed. Highly structured process - Waterfall is highly structured and organized. Its sequential approach makes it an ideal choice for large projects with multiple stakeholders and complex requirements.

This structure also helps ensure that all tasks are completed in order, reducing delays due to misinterpretation or miscommunication between team members.

Fixed Timelines and Budgets

Knowing exactly how much time and money is needed for each stage of the project makes it easier to plan out a project's timeline and budget accordingly, resulting in more accurate estimates for clients and stakeholders.

Additionally, since all deliverables are clearly stated upfront before any work begins, there’s less chance of scope creep occurring throughout the project.

This makes sure that everyone involved knows what they need to do, when they need to do it, and how much they’re expected to contribute.

The Cons of Waterfall Project Management

Limited Flexibility

Waterfall project management is a linear approach, which means there is limited flexibility to make changes once the project has begun. This inflexibility can lead to problems if the requirements of the project change during its development process.

Additionally, it can be difficult and costly to go back and fix mistakes that were made in earlier stages of the waterfall process. Not suitable for all projects.

Because it is such an orderly system, waterfall methods are best suited for projects with well-defined goals and objectives that don’t require much iteration or experimentation throughout their development cycle.

Minimal Stakeholder Involvement

The lack of stakeholder involvement is one of the major drawbacks to this type of project management style because it does not allow for changes in direction or feedback from stakeholders during each stage.

This lack of flexibility makes it difficult to adapt quickly to changing circumstances and customer requirements. Additionally, stakeholders may become disengaged during long periods with no communication or interaction on their part.

This limits the amount and quality of feedback that could be used to make more informed decisions about project progress.

Late-stage Changes are Difficult to Accommodate

Waterfall project management is a linear process and any changes that need to be made must be done one step at a time, from the beginning. This can lead to significant disruption in the workflow and difficulty in accommodating late-stage changes or requests.

Another disadvantage of waterfall project management is its lack of flexibility. Because it's so structured, it's difficult for teams to accommodate shifting priorities or sudden changes in requirements without throwing off the entire timeline.

It also requires precise planning up front, which can be difficult if there are too many unknowns about what needs to be accomplished or how long each task will take.

How to Choose the Right Project Management Methodology?

Factors to Consider when Choosing a Project Management Methodology

If your project is small in scope and has limited resources available, then a less complex methodology such as Agile or Scrum may be best suited for your needs.

For larger projects that require more structure and organization, a waterfall approach may be more suitable. You should also consider whether you will have access to remote tools such as video conferencing software or cloud-based collaboration platforms that can support distributed team members who don’t all work in one location.

The desired outcomes of the project should also be considered when selecting a methodology; some methods are better suited to certain types of projects than others depending on their goals and objectives.

Finally, it is important to factor in how much time you want to spend managing the project versus completing its tasks – different methodologies offer varying levels of control over progress tracking which might affect productivity if not balanced correctly.


The Waterfall Project Management method has been used for decades as an effective way to deliver projects on time and within budget. It’s a linear approach that works well in situations where the requirements are clear and changes can be minimized.

However, it does have its drawbacks; the lack of flexibility means changes may not be able to be implemented easily during the project lifecycle, which could result in costly rework or delays.

Additionally, since there is little opportunity for feedback or iteration throughout each stage of the process, issues may arise that weren't anticipated earlier on.

Overall though, Waterfall still serves as an effective project management framework when applied correctly with suitable risk management processes in place.
