13 Software Development Methodologies: Definition, Pros, Cons

The process of development entails diverse methodologies, some of these methods do not manifest any technical features instead deal with specific aspects like structure, syntax and timely implementation and delivery of the project.

Let us move forward and look at some advantages and shortcomings of these methodologies:

  1. 1. Waterfall Model

infograph-1

Waterfall model is as a fundamental concept in the development methodology. It follows a linear structure that demands the completion of a prior stage to start the upcoming one. Each level will be beginning only after the end of the previous level, which points to the fact that at any phase, going back to the last stages are impossible.

Pros

  • Easy to understand
  • Time-saving methodology
  • The testing phase is considered easier

Cons

  • Not suitable for the maintenance
  • Applicable only for the well-specified projects
  • It cannot predict the output
  • Cannot include the feedback of the clients at any stages
  1. 2. Prototype Methodology

This methodology gives freedom to the developers to create a prototype on the solution to present to the clients. We will receive the necessary alterations from the client side before starting the application. It can address many issues that cannot deal with the traditional waterfall model.

Pros

  • Prototype methodology reduces the risk of failure with the early detection in consideration with the requirement.
  • It clarifies the way of implementation to the clients.
  • Easier communication between the client and developer

Cons

  • Excessive and frequent changes from the client side reduce the performance
  • Hindrance on the workflow occurs due to the abrupt add-on.
  • Development cost may increase with each advancement.
  1. 3. Agile Software Development Methodology

 

Open-ended projects will be flexible that changes with the requirements and here is the importance of Agile methodology occurs. It includes various methods and practices useful for the successful deployment which gets explained in the Agile manifesto.

Pros

  • Robust feature improves the adaptive functionality
  • The developers can make necessary changes during the coding
  • The high-quality output will be different sessions which can test separately
  • Communication will be clear and transparent between the team and the client

 

Cons

  • The lack of paperwork and more concentration on the functional software
  • Lack of solid structure and non-restrictive method
  1. 4. Scrum Development Methodology

 

Scrum methodology is suitable for changing requirement projects that iterate regularly. It is initiated with transitory planning, continuous conferences and concludes with the review, and in the advanced stages, the feedback will also consider.

For the passive, yet far-reaching projects scrum can be used to get into the track.

Pros

  • Decision making is up to the team
  • Improves productivity with a daily meeting
  • No lengthy business document is required

Cons

  • Not suitable for large projects
  • Expertise developer should be there as the scrum master
  • In case if the client doesn’t get the idea, there won’t be a document to share with him
  1. 5. Spiral Model Methodology

The spiral model is flexible in the sense that the developer can make the modifications in the project even in the later stages. As the name indicates, we have a circular loop through which the developer will look for the perfect design and will continue the same until he gets the product which reduces the risk factor. At every point, he could find the vulnerable positions which can be solved or eliminate.

Pros

  • Reduces the risk factor and suitable for large projects
  • Extra features can add at any iteration.
  • It can work out with massive projects.

Cons

  • Suitable only for costly projects
  • May continue with the indefinite circulation
  • Fault in the risk analysis affects the whole project
  1. 6. Dynamic Systems Development Model

 

Being a part of the Agile methodology, each module in the project will have different principles and characteristics were the users can involve like a RAD model. The completion of the entire project using the dynamic systems model will offer the best budget under the specified time limit.

Pros

  • Timeliness of the project keep, and the end users can easily get engaged in the requirement phase.
  • More natural functions will deliver on time where the multiple modules can make in the later stages.

Cons

  • Not suitable for low budget projects
  • As it is a new approach, highly acknowledged people are needed to implement
  1. 7. Extreme Programming Methodology

 

In an unstable project environment, this extreme method will be the best choice which includes four essential subtopics like coding, testing, designing and listening. The completion of the project will be faster here, and the feedback from the clients are also be collected at every phase, and the requirement can be incorporated without much pressure.

Pros

  • Lowers the cost of the overall project
  • Makes the developers capable of satisfying all the standards
  • Less time consuming
  • Makes testing phase easier

Cons

  • Changing the requirement in the later stages will be expensive
  • Not suitable for maintenance and short projects
  • The developer will find it difficult to come up with the model
  1. 8. Rational Unified process methodology

 

The entire project divide into five distinct phases namely

  • Business modelling
  • Design and Analysis
  • Deployment
  • Implementation
  • Testing

Proper guidelines for the developers in forms of templates are the added advantage where step by step processes and examples regarding each stage are described. The quality testing is also considered with each phase by the object-oriented program.

Pros

  • Capable of fixing the errors that occurred due to the changes from the client side
  • Integration is associated with every stage, so no separate time frame is needed
  • Reuse of peripherals reduces the overall time

Cons

  • Complex stages are evolved.
  • Confusion in integration occurs because of the multiple development project team.
  • In the case of latest technology usage projects, peripheral reuse is impossible.

 

  1. 9. Rapid Application Development (RAD)

infograph-3

RAD offers a more sophisticated and natural approach on the software development with accelerated speed on each phase with the interference of the user, in such a way that the time for testing and debugging get minimised.

Pros

  • Reduces the chances to get errors since each module is developed separately and gets integrated at the end
  • The user-friendly approach reduces confusion and dilemma
  • Regular reviews from the client side make the appropriate changes in the project

Cons

  • Not suitable for low-cost projects
  • A team of expert professionals is required to record the sudden changes
  • Strict module based projects that packed for the requirements can only apply to this model
  1. 10. Feature Driven Development Methodology

 

Iteration method in collaboration with the object-oriented concept is the core of the feature-driven way. It tracks all the milestones declared at the initial stage. Before framing the domain models, the scope of the system will make at the earliest.

Pros

  • Can easily handle complex projects
  • Time consumption is comparatively less
  • 5 point process improves the performance
  • It includes up-to-date techniques.

Cons

  • Not suitable for small projects
  • The Team Leader will hold the entire abstract so that the success or failure depends on his capability
  1. 11. Lean Development Methodology

 

A lean development methodology is an advanced form of Agile in which the additional documentation and meetings are eliminated to improve the performance; in other words; it is a more focused form. After the deployment, it will cost only one-third of the whole budget with a limited workflow. The optimisation in the overall features will show a great new leap in the development phase.

Pros

  • Delivers the best service in a limited period
  • Reduces the time of development phase so that the developers can work on more projects.

Cons

  • Decision making should be at the earliest
  • Excessive flexibility in the process causes a dilemma between the developers
  • Developers can add more functionalities which may lead to change from the mainstream focus.
  1. 12. Joint Application Development(JAD) Methodologies

 

JAD sessions are the highlights in this methodology that creates an interaction space between the customer and the development team which makes the customer gets involved in the development phase too. At every stage, the customer can make the suggestions. JAD was applicable only for the system applications, but now it is used in every possible process even in the web-based applications.

Pros

  • Each session will make the customer and developer evolved in the project
  • JAD creates high-quality output with a limited period
  • The development process will be faster with few errors

Cons

  • It takes time to implement the session since proper planning requires between the team members
  • Well experienced professionals are needed
  1. 13. V Model

 

The V-shaped sequential process evolves in this method is commonly called a validation or verification process. Each phase is concluded with the test process and is suitable for low to medium sized projects. In parallel with the planning and deployment, testing phase is occupied. It includes four important types namely unit, integration, acceptance and system testing.

Pros

  • Early detection of the errors
  • Easy to implement
  • Suitable for small projects

Cons

  • It is the Least flexible or rigid model.
  • Changes in the middle of the development phase will create significant issues
  • Creating error reports at the earlier stages is time-consuming
