Traditional Software Development Life-Cycle Models Used by QA Outsourcing Companies
QA outsourcing companies are designed to deliver high value to their customers. These can perform any technical task no matter how complex it is. Besides, the organizations provide comprehensive QA consulting services to ensure the quality of software applications, improve processes and capabilities, and also market the products as quickly as possible.
Now the discussion will concentrate on the development lifecycle models which can be different.
Waterfall Model is rather of historical interest nowadays because it is not used in today’s software development projects. It is the pioneer of SDLC processes since it is a very old approach. It is a linear sequential methodology, very flexible and easy to understand. Each next stage of development can begin only after successful completion of the previous step. It is mainly used for small projects with precise and explicit requirements. In this model testing starts at the end of the development process.
Vee-Model is the same as Waterfall approach but it can be considered as its extension. In simple words, this methodology offers structured testing framework where the processes are executed in a sequential manner resembling V-shaped. It is an advanced development model, demonstrating the relationship between each stage of the development lifecycle and its associated testing stage.
In this model testing starts before the implementation phase. Each phase is thoroughly tested to make sure that it can be moved to the next stage. Testing activities begin early in the development lifecycle.
Load testing companies provide their services to improve stability & reliability of software and optimize the user experience by emulating large volume of realistic simultaneous contactors. It can help to determine the operating capacity of the program and detect defects that cause memory leaks, buffer overflow, etc. As soon as the development project approaches its completion it is time to load test it.
Iterative Model is probably one of the most popular software development approaches. The meaning of word “iterative” is repetition. Therefore, the goal of this method is to develop a system by repeating cycles and in smaller chunks at a time. With each iteration, new features can be implemented and tested till full functional software is ready to be distributed to the customers.
It is common for independent software testing companies to use various development models since all it depends on a particular project. If you want your manufactured project to be verified and validated properly, you are recommended to outsource your product development.
