Top Custom software development methodologies

Custom Software development methodologies play a crucial role in creating software built according to clients' requirements. It is very much essential that the aim, interpretation, and purpose of the project are clearly defined at the beginning of the project. In order to determine the development methodology to create custom software is an important decision. This choice must be made after all of the tasks have been concentrated complicatedly. When the intricacies, customer interest, and assets are adequately investigated, custom software application development organizations can at least start the beginnings of the project. Before doing that it is important to understand different methodologies and how they may be suitable for your project and its theories.

Custom development methodologies:

1. Big Bang Model

When the client is not sure about their project needs and how the deployment of the application will take place for simple and small projects then this methodology will be used. It has no rigid formal protocols and also it is not complicated. This model can be quite risky when the complication of the project is high. The flow of the Big-Bang methodology is stated as under:

  • The prototype needs to be created
  • When done the client will check it at its own level
  • After review completion, the necessary changes are requested by him
  • The changes requested by the client are to be implemented in the development phase
  • After the development phase, the maintenance stage comes. It is done according to the nature of the project.


  • Easy to manage
  • Provides elasticity to developers
  • Minimum resources needed
  • Appropriate for beginners


  • High risks and uncertainty
  • Weak model for long and occurring projects
  • Approved for small projects

2. Waterfall model

Waterfall Model represents the Linear-sequential life cycle model. It is extremely easy to comprehend and utilize. In a waterfall model, each stage should be finished before the next stage can start and there is no overlapping in the stages.  It is an inflexible model that follows a specific process. No one can replace any stage. The sequent flow of the waterfall model empowers the software development company to follow the thorough strategies and that no functionality can cover the other. The waterfall stage consists of those stages which the developers need to follow and also they cannot jump to other stages before the previous stages are completed.

These stages are stated as under:

  • Asking the clients about their needs
  • Sampling of module
  • Implementation of the plan
  • Testing of software
  • Deployment
  • Maintenance


  • Simple and easy to use
  • Clear defined stages
  • Easily arranged tasks
  • Appropriate for both small and big projects


  • Deployment is possible only when the last stage is completed
  • Highly risky and uncertain
  • Hard to calculate development within stages
  • The documentation process takes a lot of time

3. Agile Software Development Model

The change done in this methodology is permanent, mainly in technology circuits. This methodology is mostly preferred by the developers and is one of the most popular software development methods. This software model is elastic and decreases the risk chances as the custom software is divided into small bits called iterations. The agile model states that each and every project needs to be operated differently. In Agile methodology, the tasks are divided into small time boxes in order to transfer features for a release. 


  • Lessor no planning is required
  • Provides flexibility to developers
  • Encourage teamwork and cross-training
  • Appropriate for specified or changing requirements


  • Lots of risk for sustainability, maintainability, and extensibility
  • Not good for handling complex difficulties
  • Due to lack of documentation, the transfer of technology to new members is challenging
  • High individual dependency as less documentation is generated

4. Rapid Application Development Model (RAD)

This is one of those methodologies which has the objective of completing the development project with high-speed which consists of a combination of speedier integration and design which increases the speed of project development. It prompts speedier feedback, quicker amendment of errors, and arriving at your objectives as quickly as could really be expected.


  • Advancement can be measured
  • Stimulates customer feedback
  • Decrease in development time
  • Speedy review occurs


  • Highly skilled developers and designers are required
  • Tough to maintain its documentation
  • Management difficulty is quite high
  • Small and low-scale projects are not suitable for this methodology

5. Scrum Development Methodology

Just like Agile development methodology, scrum development also has high ranks in its popularity. In order to attain the results, the model splits the working process into tiny bits and every bit is treated with a different strategy. It has the ability to bring slow-moving projects on its tracks. The sequence model of this methodology is:

  • Planning
  • Meeting
  • Conclusion


  • The developing team has all the decision making authority and responsibility
  • Developers can provide high-quality products on time
  • Task improvement can be followed, and incessant updates on the advancement are gotten
  • Tiny bits and feedback makes the process changes easier


  • High accurate time and cost estimation is required
  • Large-size and long-term projects are not suitable for this model of methodology
  • The budget may suffer because of not specifying the time and budget of the project
