Nevertheless, an organization should keep in mind that this software development approach will require a higher budget. Code should be easy to read and concise so it behaves as expected and others can collaborate with you without adding more bugs. To make that possible, developers need to be able to communicate clearly the requirements and their intentions.

This can be a challenge for more introverted programmers, who may until that point have felt that they do their best work “in the zone”, independently. Fighting against this mindset, especially if the https://www.globalcloudteam.com/ developer is more senior or highly specialized, can be challenging. Studies have shown that pair programming can result in 15% fewer defects in code, depending on the thoroughness of the coders.

What is Pair Programming

This can be achieved using a variety of tactics and one special methodology is pair programming. Sharing best practices between partners leads to better overall code. In particular, having to be accountable to your partner discourages both members from taking any shortcuts or hacks.

Traditionally, the pair roles are divided between the driver and the navigator. The former is responsible for achieving the small objectives or steps, one by one. The latter reflects on the big picture and gives the next directions. As the navigator, you can see way beyond what the driver is currently coding.

Pair programming in interviews

Since the pair must work as a team, there is little benefit for one developer to work with a distracted partner. The distracted programmer is likely not looking to catch errors or check the consistency of the code, leading to more problems down the line. With pair programming, junior developers can receive faster training, while experienced developers can level up their expertise.

Like a database developer and a middle tier developer working together can improve the delivery of code. For some organizations, pair programming simply isn’t the right fit for their situation. However, a growing number of companies are finding that pair programming has a variety of benefits, including saved development time, higher-quality code, and better training and onboarding. As a result, everyone on the team is working together to build the most successful, best version of the product possible. With pairing, it is like having somebody review your code instantly and regularly. Two people have to be there and understand the program being written.

Improved team morale

Eventually, pair programming lets you ensure the just hired software engineer is really a good fit to the team by defining short term goals and measuring success on the go. When you are solo programming, you make micro decisions on how to effectively address problems. You take into account what you know of the code base or think about particular conflicts that may arise now or in the future. The matching experience is made even worse by a lack of patience. When dealing with persons of varying skill levels, this might happen. Especially if a more experienced developer doesn’t give their partner enough time to comprehend their code.

  • Some businesses may adopt the practice, while others may opt not to use it.
  • Apart from the retention rate, fewer mistakes are introduced in pair programming if the programmer is not in the state of being fired.
  • This means that when two people work on one problem collectively, the problem is solved faster than that of one person working on one program.
  • Working directly alongside the knowledgeable programmer, the other coder will gain expertise more quickly than by working on tasks alone.
  • In a truly cross functional team you can have a developer and business analyst pairing together.

If two developers are not compatible pair programmers, consider pairing them with others on the team to see if a better match can be made. While coding, the driver should have a constant stream of verbal communication with their partner. This is also referred to as “programming out loud.” If the driver is not doing this with their navigator, pair programming isn’t as efficient.

How does pair programming work?

The programmers may also swap roles every few minutes to keep things fresh and lively in pair programming. Pair programming is a software methodology in agile in which two programmers work together on a single workstation. One useful technique that can keep pairs from falling into this antipattern is to use a Pomodoro timer. These timers will keep a running countdown of the seconds as you work in 25-minute increments, and then tell you to take a break for five minutes. By switching roles between the driver and the navigator during these breaks, a pair can avoid lapsing into extended sessions with just one driver. When you have two or more people trying to work together, the first thing they need to do is agree on a work schedule.

Tuple ensures a low-latency connection, so typing on another screen remotely is not met with issues. This remote pairing tool claims to be lag-free and includes basic integrations with Share.js, which allows simultaneous editing. Think about the developers you work with and their preferred work style.

Why is Programming in Pairs Better than Code Reviews?

Lets say the story has UI to be implemented, service layer changes to be done, data access to be modified and database schema changes. All these changes can be performed by a primary developer and swapped at each point with a different partner. I hope you can realize the benefits of taking such an approach. To me pair programming is very fundamental to Agile and one of the most required tool for building a truly cross functional team.

pair programming definition

Pair programming, as the name suggests, is a software development practice in which two programmers collaborate on a single workstation at the same time. This collaboration can be done either in person or remotely, in which case pair programming definition you’ll need software for screen sharing and real-time editing. People who haven’t tried pair programming have a vision that pair programming might double the cost and time of the project because it takes two programmers.

The Benefits of Pair Programming

Typically, one of them is a driver (or a pilot) and the second one is a navigator. The driver writes the code and the navigator reviews the code and plans the action. The goal is to increase software quality without impacting time to deliver.
