Several opportunities have developed in the last few years for developers and the future that software development methodologies have is quite exciting that it was even a few years ago. The developer now has to be on their feet because of the changes they have to adapt to provide software development services to their customers.
The changes in the software in 2018 were influenced by artificial intelligence (AI) technologies and big data. According to pundits of the industry AI, technologies and algorithms along with big data will continue to contribute heavily into software development and any company that aims to provide custom software as a service has to adopt the new methodologies. Here are the 10 best software development methodologies for 2019.
1. Agile Software Development:
For starting a software engineering project Agile software development can be viewed as a conceptual framework. This methodology allows the developers to develop any software in short iterations so that the risk can be minimized as a result many mobile application development companies are using this methodology.
Agile software methodology is a term that is used for describing several methods that used and designed specifically to meet the requirements of the ever-changing fast-paced environment so that developers can produce the final product as soon as possible.
2. Black Box Testing:
Black box testing is also known as the Behavioural Testing and is quite important in software development services because in this the software is tested where the tester does not know about the internal implementation of the item that is being tested.
This is a crucial part of software development because the testing allows the tester to identify any incorrect, missing functions, data structure errors, errors in performance, errors in initialization and termination and issues like these. Black Box Testing as a software development methodology focuses on developing the functionality of the software system as a whole.
3. Prototyping Model:
One of the most popular Software Development Life Cycle (SDLC) models is the prototyping model in, in which a prototype is built so that it can be tested and reworked on if necessary.
This methodology suits well for any custom software development company if they know in detail the requirements of a project ahead of time. A developer can use two kinds of the model in this method, they are
- Rapid-throw-away prototyping: it allows exploring of the ideas and also works with customers’ feedbacks.
- Evolutionary prototyping: software is developed and then it is refined based on the customers’ feedback and the refining continues until the product is accepted.
4. Rapid Application Development Model:
For rapid prototyping purpose, this methodology is used as it requires minimal planning, as a result, many companies that provide custom software as a service used this methodology in software development. It is an incremental model that allows the developer to develop several components parallel. The Rapid application development model has several phases that can be utilized by a developer.
The phases are:
- Data modeling
- Business modeling
- Process modeling
- Application generator
5. Spiral Model:
The spiral model is a combination of two models; they are iterative development along with the waterfall model. However, the iterative development is used with the waterfall model that is controlled and systematic, which enables a refinement via each iteration around the spiral.
In the spiral there are a number of loops and each loop can vary as per the project. The loops are a representation of each phase in the development method of the software. The Spiral model is especially helpful for developers because it allows early identification of any issues thereby reducing the project risks.
6. White Box Testing:
Unlike the Black Box Testing, the tester is required to have adequate knowledge of programming so that he/she can choose the inputs to work with on the paths for the coding and determine the outputs.
The White Box Testing is especially critical in software development as it enables the developer to identify any internal security issues, any paths that are poorly structured, expected outputs, conditional loops in functionality and so on. As a result, this methodology is often used by custom software development company that aims to be the best in the market and provide the best service to their customers.
7. Extreme Programming Methodology:
In the Agile models of software development is quite beneficial in a software development framework since it improves the software’s quality. It is also known as XP methodology and the feedback and involvement of the customer in this software development methodology are quite high.
8. Joint Application Development Methodology:
End users in this methodology have immense involvement in the design and development application. The end users are done through JAD sessions, which are conducted in succession of collaborative sessions. This methodology allows the expansion approach based on requirement-classification and user-interface that accentuate and confirm the software system. As a result, this methodology for software development is quite beneficial for mobile application development companies.
9. Scrum Development Methodology:
For the purpose of managing and developing the products, this incremental and iterative software development framework is used. This is part of the agile software development framework that has a flexible development strategy in, which a team of developers works as a unit to accomplish a particular target. In this method, an empirical approach is followed, which is evidence-based and centers on maximizing the ability of the team to offer quick delivery of the product.
10. Dynamic System Development Model Methodology:
Dynamic System Development Model is based on the methodology of RAD (Rapid Application Development) and is part of the agile software development methodology, which is incremental and iterative. This method focuses on four phases of a software development framework, which are:
- Design and build iteration
- Iteration of prototyping
- Study of the feasibility and business
While each of these software development methodologies has its own pros and cons, it is up to the developers to decide on which methodology they should use for the development of their software. But one fact remains the same, i.e. the software development methodologies are meant for better functionality of the applications that are fully tested and integrated as a whole system.
