In this day & age, the advent of new and advancing techniques and methodologies is revolutionizing the realm of software development. Software engineers all around the world are adopting new methods for development, programming as well as testing, which simplify the process and make it even more effective. Pair programming is among these newly adopted techniques, which involves two developers/programmers with proficient knowledge of their specified field. Therefore, to elaborate more on the same, following is a discussion on pair programming.
As suggested by the name, pair programming involves two programmers who share a single workstation, and collaborate their efforts to write and test code. A type of agile software development technique, pair programming originates from extreme programming (XP), which is a software development methodology that is used to improve the quality and responsiveness of the software as per the changing requirements of the client. As stated before, pair programming involves two programmers who are an integral part of the whole process.
In this technique, one software programmer plays the role of the ‘driver’ and is responsible for controlling the keyboard & mouse for writing the code. Moreover, the driver plans the process of and takes necessary actions to fulfil them, while communicating it to the other member. On the other hand, the other programmer serves the role of the ‘navigator’ and takes up the task of reviewing the code written by the former programmer. The navigator provides tactical and analytical feedbacks based on the observations made by him/her during process. These roles are regularly traded by the programmers, which further helps them to validate the quality of the whole process.
Pair programming is an extremely advantageous programming technique, which offers developers an effective way of developing a software with unique and innovative features. The features of this technique are several, some of which are described below:
Pair programming can be termed as one of the most beneficial way of coding and programming, as it involves two experienced and talented individuals who collaborate their skills and expertise to ensure the quality of the software under development. With the help of this method, programmers can increase the speed of writing effective codes, which can then be tested and implemented by the other members of the team. Other advantages of this method are:
Though, pair programming offers various advantages there are yet some challenges of this technique that make it quite difficult to implement. From facing difficulty in finding programmers willing to work together, to encountering issues like experience mismatch, personality conflicts, etc., the hurdles in this process can be many. Hence, here are some of the challenges encountered by the team during pair programming:
The relevance of pair programming is being recognized worldwide by both software engineers and scholars. It has become an effective way of writing and testing codes, as it involves two experienced engineers who monitor the process regularly and make necessary modifications to improve its quality and effectiveness. Though there are some shortcomings of this process, yet it is one of the most efficient way of assuring the quality and functionality of the software, during the software development life cycle (SDLC).
