When you are venturing into the mobile app development industry, it is pretty hard to decide how much an app development will cost, which technology to use, which methodology to follow and many others.
You might witness countless articles on the internet debating and detailing about the app development cost, right tech stack to choose but getting the right information on app development methodology is still a task.
In this article, we will be helping you to figure out the difference between agile and waterfall in order to let you finalize the right methodology for your app development project.
Taking the same thought ahead, there are two methodologies currently available in the market- Agile and Waterfall. Though there have been numerous articles written on such topics, still there are some questions and doubts about the choice of a particular approach to the development. So, without further ado, let’s check out what is the difference between the methodologies of agile and waterfall along with gaining an understanding to choose the apt one.
Waterfall Methodology for Mobile Application Development
The classical waterfall model is the most obvious way to develop an application. It is a more simple and idealistic model that describes the application development project activities in a linear way.
In the classical waterfall model, one particular project is divided into different steps-
- Feasibility Study
- Requirement Analysis and Specification
- Coding and Unit testing
- Integration and System testing
In this model, we can’t proceed to the next step without completing the previous one. While dividing the project into different steps, the waterfall methodology does come up with its own set of advantages and disadvantages.
Let’s check out those advantages and disadvantages in order to make wise decisions in the end-
Pros of the Waterfall Model:
- The waterfall model is simple, manageable and easy to understand. Each step carries specific deliverables and a review process with clearly defined steps.
- Throughout the waterfall app development phase, one cannot move to the next stage without completing the previous one. Hence, it acts as an advantage to clients who wants to make changes in the app in the middle of the app development. Though it will cost a bit, it certainly gives the freedom to make changes as per the trend or need from scratch level.
- The classical waterfall method is suitable for the project with minimum requirements.
- Another noteworthy advantage of Waterfall is, with it, it is easy to arrange a task in the waterfall model due to its well-documented process and results.
- In the waterfall model, steps are concocted and completed one at a time without overlapping the steps.
Cons of the Waterfall Model:
- Once the application is in the testing stage, it becomes quite difficult to go back and change something that was not well-documented, planned or thought upon at the concept stage.
- The most significant drawback of the Waterfall development strategy is that you cannot return to the previous stage until the whole life cycle gets completed.
- The classical waterfall model is not suitable for the projects where requirements are at a reasonable to high risk of changing.
As this was all about Waterfall, let us now figure out what is in the store of Agile methodology.
Agile methodology Application Development Approach
Agile methodology is an iterative, rapid application development approach that ensures a proper channel of communication while helping both the clients and application developers to execute the desired mobile application process. The agile methodology is designed to adapt to change requests quickly.
Furthermore, the whole process is divided into different stages, making the whole app development process works smoothly and flawlessly. Those steps are-
- Requirement Analysis
- Unit Testing
Pros of Agile Methodology:
- The most important and foremost benefit of using Agile methodology for app development is pair programming. it reduces the number of errors in the development or coding phase.
- By using time-boxed, fixed schedule Sprints of 1-4 weeks, new features can be delivered quickly with a high level of predictability. The whole process also provides the opportunity to release or beta test the software.
- An Agile approach provides a unique opportunity for clients to be involved with the mobile application development company throughout the project, from prioritizing features to iteration planning and review sessions to frequent software build containing new features.
- Here in this method, more attention is given to interactions that are emphasized more rather than processes and tools. Customers, developers, and testers constantly interact with each other in order to bring the best result.
- In the agile method, the changes can be made and the marked features can be added or removed as per the consumer feedback.
Cons of Agile Methodology for Mobile Application Development:
- Less predictability.
- The process requires more time and commitment.
- In the absence of any formal documents, it becomes difficult to make important project decisions for application development like- design decisions that require external experts to review it.
Cost Difference Between Agile and Waterfall :
These days businesses are now shifting towards agile methodology who were earlier dependent on traditional waterfall methodology. And the reason for that shift not only depends on the Agile’s flexible approach but also because of its cost-effectiveness.
The ROI of agile methodology is relatively higher than of waterfall methodology due to less documentation, thus, more time can be given to the actual development process than in gathering information.
So, if a business is playing to opt for agile methodology, it is sure that the end product will match the expected result that too, without spending much.
