Why Waterfall Development is the Best Option



Waterfall development is a process-oriented software development process model. It consists of a series of steps in which development progresses in a linear fashion from one step to the next. As opposed to Agile development, in which the process is iterative, Waterfall development is a singular process that takes your project to completion with predefined success parameters.

Let’s discuss why Waterfall development is the best option:

Definition of Waterfall Development

Waterfall development is a type of software development that follows a sequential design process. It is rooted in the idea of linear-sequential life cycle model where progress is seen as flowing steadily downwards through the phases of requirements analysis, design, coding, testing and maintenance. This mode of software engineering emphasizes strict documentation and rigorous testing to ensure quality – both in the initial coding process and long-term maintainability.

This method has certain advantages over more iterative design processes such as Agile and Extreme Programming (XP). Before adopting any software development process, it’s important to first understand the concept of Waterfall Development and determine if it’s the right approach for your project. Below are some key components worth considering:

  • Clear stages with specific deliverables – By providing clear-cut steps during each phase with specific goals, Waterfall Development establishes direction for more uniform process flow overall. As tasks are completed within each phase, project teams are able to recognize progress on an incremental basis.
  • Documented requirements leverage long term maintainability – With Waterfall Development, emphasis is placed on thorough requirement analysis along with regulatory compliance documents like security policies. These up-front analyses create lasting relevancy by helping developers build better code from the outset, leading to fewer bugs down the road.
  • Easier stakeholder approval – When stakeholders have already been consulted early on in the process due to requirement documentation, iterations are minimized leaving less room for doubt about approval or decision making down the line. This also helps prevent costly problems as well as frustrations allocating resources or dealing with changes from stakeholders later in the process.

Advantages of Waterfall Development

Waterfall development is the process of developing software using a sequential, step-by-step approach in order to contain costs and reduce overall risks of a project. It involves planning out each step of the project and ensuring that each is finished before continuing to the next stage. This type of development has been used for many years and remains one of the most widely adopted processes by software development firms.

The advantages of waterfall development include:

  • It allows for detailed planning which helps foster strong communication between all parties involved in the project.
  • It ensures that tasks are completed sequentially, allowing for a clear understanding of expectations while controlling costs and timelines more effectively.
  • It is easier to allocate resources throughout the process due to defined milestones which help teams stay on schedule.
  • It helps promote consistency across projects, allowing organizations to uphold their standards and increase quality control overall.

Benefits of Waterfall Development

Waterfall development is a popular software development methodology that focuses on linear processes and tasks that must be completed in a certain order. This type of development has been proven to be effective for delivering projects with quality and speed.

In this article, we will explore the key benefits of waterfall development and why it is the go-to software development methodology for many developers.

Clear Documentation

One of the main benefits of using the Waterfall method is having a clear documentation of each step of the development process. This can help project teams keep an eye on every aspect and makes it easier for them to spot gaps and mistakes in their development endeavors.

Each step in the Waterfall model produces documentation that outlines how requirements should evolve with each phase, as well as serves as a feedback loop that ensures all members are on the same page. Clear documentation also streamlines management responsibilities so analysis, planning, and evaluation processes can be made more efficient. Plus, clear documentation allows teams to take a systematic approach towards problem-solving and product improvement initiatives.

Easy to Manage

Waterfall development is an easy system for project managers to master and track. The linear structure is simple to understand – when following waterfall spirit, teams complete one step in a project before moving on to the next. This means that project managers can measure performance and make changes quickly, as teams are mostly working on discrete projects. As one step is completed, the next must begin in order for the project to move forward. This gives team leaders the ability to see which sections of a project are behind without any guesswork.

Additionally, it’s not necessary for every step of a project to be completed before continuing on to the next – decision makers can isolate problems and assign individual teams that can troubleshoot while the rest of the group continues with different tasks in other areas. This makes it easier for leaders to utilize resources more effectively and save time in the long run. Waterfall development also allows easy scaling up or down depending on budget or context (such as time restraints). All these factors make waterfall an ideal model for many projects because it provides visibility into all stages of a project and allows controlled management over its progress.

Reduced Risk

When distinguishing between Waterfall development and other knowledge-based approaches such as agile development, one of the key distinctions is the approach to risk. By breaking the project into distinct phases, each with its own set of deliverables and deadlines, Waterfall methodology helps reduce risk throughout the entire process.

For example, by committing to high-level requirements well before design begins, high-level risks can be identified early on. This allows your team to make decisions about trade-offs and take corrective action before too much has been invested in a particular strategy. Likewise, by making sure that design meets requirements before a single line of code is written, technical risks are mitigated early on. In this way, Waterfall methodology can help focus resources on mitigating only those risks which are most important for success.

In addition to reducing the overall level of risk during a project’s lifecycle, another key benefit of Waterfall methodology is predictability: projects completed using this approach usually have a higher degree of control over time, cost and scope for delivery than when other methods are used. This results in reduced rework time and fewer surprises later down the line – meaning your team can keep their eye on what really matters: delivering a working solution while keeping costs low.

Disadvantages of Waterfall Development

Waterfall development is often seen as the best approach for product development but there are some key drawbacks to consider as well. It requires a lot of upfront planning and the entire structure of the project must be designed before any coding can begin. It can also be difficult to make changes quickly if new requirements are identified mid-way through the development process.

Despite these drawbacks, there are still ways to make waterfall development a successful option:


One of the main disadvantages of using waterfall development is its inflexibility. The process relies entirely on an orderly and linear method of development with each step having to be completed before the next can begin. This can restrict a project’s ability to make changes or adapt quickly in response to user feedback or changing market demands.

As each phase must be completed before the other can start, any addition of requirements during later stages will force developers to unravel some elements already completed in prior stages, potentially introducing errors and flaws in the development process. Furthermore, activity going down one branch may need to be redone if re-conceptualizing is required from a different perspective. This means resources have been wasted and additional time must be allocated for minor changes that would have been relatively easy for agile methodologies.

Thus, waterfall falls short when trying to bring customer value quickly with new features or bug fixes.

No Iterative Development

One of the most prominent disadvantages to the Waterfall model is that it does not accommodate iterative development. With the Waterfall model, each stage needs to be completed fully before moving on to the next. This makes it difficult to make any changes or updates once a stage has been finalized and approved. This can also make it difficult for developers to adjust quickly to customer requests or changes in product requirements. Since each stage must be completed in order, if adjustments are required after a certain point, the timeline for completion of the project will be disrupted, causing delays and missed deadlines.

In addition, there is an increased risk that critical bugs or issues could be missed until late in the development process since changes cannot be made during each iteration until all stages have been completed. This type of development discourages developers from taking risks with new ideas since fixing any mistakes could add time or cause additional coding problems that could threaten future design elements and ruin project implementation deadlines.

Poor Requirement Analysis

One of the primary disadvantages of waterfall development is that the requirements for the system are incomplete, or not well understood when development begins. A poorly defined system can cause long-term technical debt that needs to be addressed later in the lifecycle. Additionally, with such a detailed plan for implementation established at the beginning of development, it can be difficult to integrate feedback from stakeholders and team members who weren’t involved at the outset. This can lead to frustration among team members and stakeholders who feel like their input isn’t being taken into consideration.

Another issue with waterfall development is that changes are more costly than in other development methods because they require a lot of reconfiguration and reworking due to previously written code and approved designs. Additionally, not all projects are suited for waterfall as it focuses on large scale projects which involve a great deal of complexity while smaller projects can be handled more effectively using agile methodologies.


To summarize, Waterfall development is a reliable process for developing and deploying any given product. It uses a defined sequence of steps that are repeatable and trackable. When managed correctly, it requires less time, cost, and resources than other methods. Additionally, the primary benefit of this method lies in its predictability, as developers can accurately forecast the timeline of development due to clear deliverables and hard deadlines. This makes it ideal for projects where complete accuracy and consistent results are key aspects of the finished product.

Ultimately, with its emphasis on clear deliverables and customer requirements coupled with its predictable timetable for completion, Waterfall development is the best option to help teams achieve their desired objectives in an efficient way that provides long-term value to their customers.
