Agile vs Waterfall: Which Methodology Works Best for Custom Software Development?

Are you a business owner looking for the best method of software development for your company? With so many approaches to software engineering available, it may be difficult to decide which one is right for your project. Two of the most popular are Agile and Waterfall, but how do you know which is best?

Software development involves complex processes that can take months or even years if managed incorrectly. For this reason, businesses have been utilizing various models and methodologies to ensure they are receiving the best results and optimal value from their investment in custom software development.

Agile and Waterfall are two of the most popular methods used by the top custom software development company experts. Both approaches have different benefits and drawbacks depending on the type of project and its complexities. However, there are better ways to determine which methodology will work best based on specific criteria such as budget, timeline, resources, etc. Read on to compare Agile vs Waterfall in terms of suitability for custom software development projects.

Comparing Agile & Waterfall approaches

  1. Overview

Agile and Waterfall are two popular methods of software development. Both approaches take a different approach to the same end goal – providing an efficient and effective means to develop a software product. While Agile is a more modern, adaptive approach to developing software, Waterfall is a traditional linear approach which involves more planning at the outset of the project. The two approaches differ in their management style, process, people orientation, and relationship between developers and customers.

  1. Management Style

Waterfall follows a strict and rigid structure with each phase of development requiring completion before moving onto the next step. This management style is beneficial for larger organizations as it requires better organization and discipline when efficiently carrying out tasks within deadlines. On the other hand, Agile encourages continuous progress with feedback from customer requirements that shape project results as time progresses which makes it beneficial for smaller organizations or businesses with limited resources or need immediate results due to tight deadlines or customer requirements.

  1. Process

The Waterfall process involves repeating sequential steps such as requirements gathering, design specifications, coding or programming tests before progressing on to delivery or maintenance stages such as deployment and customer service support. In contrast, Agile takes small steps that allow customer feedback to shape the product overnight while allowing room for improvement before completing any specific feature set within an iteration (sprint). This translates into fewer errors due to improved testing done along each deliverable during integration testing stages versus waiting until all large functionalities are combined into one whole project prior to production releases when using Waterfall processes.

  1. Design & Development Approach

The primary difference between Agile and Waterfall is in their design and development approach. Agile is an iterative, step-by-step process that allows for fast iterations of development and testing cycles. On the other hand, Waterfall methodology is a strictly linear approach in which each phase of the project must be completed before moving on to the next phase.

  1. Overall timeline

Agile focuses on shorter release cycles with frequent iterative changes in order to get an end product out faster than traditional Waterfall models. Because it is so incremental, Agile actually encourages longer project timelines as well—as a project grows and builds momentum over time, enhanced engagement can occur within the team as well as with stakeholders. In contrast, Waterfall projects focus on creating a plan up front with rigid deadlines; if things don’t finish “on time” they are deemed a failure.

  1. Cost efficiency

In terms of cost efficiency, Agile offers more value since it can avoid long periods of inactivity during phases that would occur in typical Waterfall projects like requirements gathering or coding. Agile also allows teams to rapidly develop product features at a much lower cost compared to Waterfall by eliminating useless features quickly while sparing costs associated with their development and launch efforts. With Waterfall projects however, these costs can add up quickly as commitments have been made up front without any guarantee that direction has been headed in a successful direction until after product delivery has occurred months later.

Pros And Cons Of Each Method

If you are still confused, below specified pros and cons can help you understand when to hire custom software developer. Take a look:

Pros of Agile:

– Faster development timeframes

– Improved customer engagement

– More flexibility to adapt quickly to changes

Cons of Agile:

– Lack of attention to detail

– Higher cost due to the frequent software updates

Pros of Waterfall:

– Significant focus on accuracy and details

– Lower cost due to less rework

Cons of Waterfall:

– Longer development cycle times

– Inflexibility when responding quickly to change

Things To Consider While Making Decision between Agile VS Waterfall development

1. Speed and Duration

Agile methodologies are designed to be “fast”, with focus on early feedback and allow the development team to quickly course-correct if needed. Waterfall is a linear approach that generally requires more planning time and longer project duration.

2. Visibility

Agile allows for visibility throughout the entire project lifecycle, including on-going communication between key stakeholders and developers as well as continuous updates on progress towards goals. Waterfall provides a high-level overview of progress during the design and implementation phases, but offers limited visibility of day-to-day activity.

3. Quality Assurance

Due to its focus on early feedback, Agile methodologies provide opportunity for quick validation of results while promoting quality assurance activities such as user acceptance testing (UAT). With a Waterfall approach, risks are greater in regards to quality assurance since there is less time for UAT or other QA activities until the end stages of a project lifecycle when all project components need to ensure meet expectations of users/client requirements.

4. Cost & Budget

The cost associated with an Agile methodology may be higher than traditional waterfall due to its iterative nature which requires additional resources in terms of time and money; however, it can also save money down the road since defects are identified earlier which reduces rework costs later on. On the other hand, Waterfall tends to involve fewer resources upfront, but may be more costly if features or changes require revisiting during later phases after projects have reached their regular flow of operations.

5. Risk Management

With its iterative nature, Agile approaches mitigate risk by allowing development teams to quickly review changes in real time with key stakeholders; furthermore, flexibility allows teams to accommodate any changes requested at anytime during different sprints without requiring any extra process overhead or delays due to lack up updating requirements documentations prior each development phase completion before moving forward into the next one (as required with Waterfall development).

6. Scalability & extensibility

Both approaches offer scalability when creating large applications; however, agile provides more flexibility through iteration cycles that allows resolutions faster derived from continuous feedback from key stakeholders whereas with Waterfall it may be harder to make tweaks and extended functionality in time as requested by end users as relevant information would not have been provided/collected since the beginning stages given waterfall’s linearity.


In conclusion, Agile and Waterfall are both effective methodologies for custom software development that have proven beneficial to many companies and organizations. While Agile focuses on quickly delivering high-quality working software with continual feedback from users, Waterfall’s step-by-step approach gives teams better visibility into progress and resource allocation. Ultimately, the methodology chosen should depend on a company’s individual needs and issues such as timeline, budget, scope of the project, and team size. Taking all of these factors into consideration can help determine which methodology is best suited for a particular project’s success.
