What does pair programming mean?

The navigator looks around, double-checks the code, and maintains an eye on the larger picture. The approach to the development of software, in which the code is written by two programmers at one computer. You can use pair programming for many different tasks. Typically, we pair program naturally when we are stuck and ask for a colleague’s help.

The driver carries out the navigator’s instructions, but has the opportunity to make corrections or ask for clarification. The driver and navigator regularly switch roles every 15 minutes or so. Developers do their best work when they’re inspired and empowered, as we discussed recently in this post. Another method for boosting efficiency is pair programming, Let’s take a look at pair programming advantages, concept, and challenges of pair programming. A software development technique, part of extreme programming, in which two programmers work together at a single keyboard, one coding while the other observes and reviews. The process starts with the developers receiving a well-defined task.

The empirical studies tend to examine the level of productivity and the quality of the code, while meta-analyses may focus on biases introduced by the process of testing and publishing. In addition to preventing mistakes as they are made, other intangible benefits may exist. For example, the courtesy of rejecting phone calls or other distractions while working together, taking fewer breaks at agreed-upon intervals, or shared breaks to return phone calls .

Pair programming is an agile software development technique in which two programmers work together at one workstation. One, the driver, writes code while the other, the observer or navigator, reviews each line of code as it is typed in. While reviewing, the observer also considers the “strategic” direction of the work, coming up with ideas for improvements and likely future problems to address. This frees the driver to focus all of his or her attention on the “tactical” aspects of completing the current task, using the observer as a safety net and guide. Pair programming is a practice in agile software development where two programmers share a workstation.

What Is Pair Programming? Advantages and Challenges

If you have the opportunity to choose your pair programming partner, it’s best to seek someone who can fill a gap in your knowledge or provide you with a different perspective. It is more common than you might think, and it defeats the point of pair programming. To create a safe atmosphere for collaboration that encourages developers to share their knowledge. One person is the “driver,” and the other is the “navigator” in pair programming. The driver is the individual who is actively writing code at the keyboard.

The driver focuses on the specifics of coding, while the navigator checks the work, code quality and provides direction. “Two heads are better than one,” especially when paired with an experienced mentor who knows when to give you a nudge in the right direction and when to step back. Connect with a senior developer for an effective remote paired programming session now. This form of pair programming is performed in conjunction with Test-Driven Development. One person writes a test and the other person makes the test pass.

From help with JavaScript, Swift, React, and more, keep up to speed with good programming practices. They’ll sit next to the driver, but they won’t be writing any code. Having a real-time check on their work by another programmer can help coders identify bugs, typos, and other mistakes that they might have missed if they were working alone.

However, this is a misconception that needs to be clarified. Most of the time, code reviews happen when somebody else tries to add some functionality to your code, or fixes bugs. But by then, you, as the original programmer, might not even be around to appreciate the code review. Two experts can generally work within any pair programming style. Advanced programmers may prefer the ping-pong style, as it allows them to have even participation. Pair programming helps developers understand each part of a codebase, meaning the environment will not be dependent on a single person for repairs if something breaks.

Are we missing a good definition for pair programming? Don’t keep it to yourself…

Common logic might dictate that pair programming would reduce productivity by 50%, because two developers are working on the same project at one time. According to a blog post on Raygun, pairs work about 15% slower, which is an improvement but is still less than the productivity of two separate programmers. Don’t be the person who insists your pair programming partner uses your hyper-customized Vim or Emacs with a thousand plugins unless they are as comfortable with Vim or Emacs as you are. By insisting on an environment that is unfamiliar to your partner, you’re doubling the cognitive load they must work through. One best practice in pair programming is that the two coders maintain an ongoing conversation.

Pair programming is a technique wherein two individuals collaborate on a single program. The “driver” writes the code, while the “navigator” checks each line of code for errors. Shy people, introverts, and coders who prefer to work quietly might all find pair programming slows them down or undermines their work quality. Many businesses mistakenly assume the costs would double—two programmers’ salaries versus one for the same output. But because two programmers can collectively work more quickly and fewer mistakes than one programmer coding alone, the actual cost increase is less than double.

You don’t need to go overboard with expensive professional audio equipment. Instead, the navigator will pay close attention to the code the driver is producing and will offer advice and ideas as needed. As they code, this individual will strive to verbalize as much of their thought process as possible.

They will be in charge of considering the classes, variables, functions, and algorithms that must get coded for the program to achieve its goal. It can be counterproductive for certain types of coders. Navigator is observing each and every line of code written by driver, so mistakes or error can be detected easily. They stand in different relationships to the problem by virtue of their functional roles.

You can only swap one time if the session is less than 60 minutes long. Having only one person lead could be more efficient if the session is shorter, but you can still switch halfway through. The collaboration, plus the fact that each technician is validating the other, ensures that more thought goes into the writing of each routine. It also helps to make the code self documenting or, at least, better documented.

One programmer writes the code while the other watches, reviews, and provides guidance. This style works well for a novice paired with an expert programmer. The navigator role can range from a reserved approach to a tactical hands-on role. Pair programming is an software development technique in which two programmers work together at one workstation.

This is intended to free the driver to focus all of their attention on the “tactical” aspects of completing the current task, using the observer as a safety net and guide. Pair programming is a collaborative definition of pair programming effort that involves a lot of communication. The idea is to have the driver and navigator communicate, discuss approaches and solve issues that might be difficult for a single developer to detect.

It boosts team cohesion and job-satisfaction levels.

Indeed, with the changes in the way people work and the increase of remote work, more and more developers are doing pair programming sometimes hundreds of miles away. Code Fellows talks about how it could help programmers learn from their peers in this blog post. It would allow programmers to get instant face-to-face instruction, which is much better than online tutorials and faster than looking for resources on the Internet. Plus, you can learn things better from your partner, especially in areas that may be unfamiliar to you. Developers can also pick up best practices and better techniques from more advanced programmers.

Still, you may drift away occasionally if you are following. It’s good to turn on your video camera when pair programming, https://globalcloudteam.com/ even if it’s unnecessary. The frequency with which you must switch roles gets determined by your degree of experience.

Benefits of Pair Programming:

Sometimes, drivers are supposed to speak loud as they write code. Some people may not agree on idea of sitting, literally shoulder-to-shoulder, with a colleague for eight hours a day. Some experienced developers are more productive in solo rather than in pair programming. Pair programming allows team members to share quickly, making them less likely to have agendas hidden from each other. This helps pair programmers learn to communicate more easily. “This raises the communication bandwidth and frequency within the project, increasing overall information flow within the team.”

Reduces Error – When there are 2 people in a team, they are more likely to do the right thing, since one person will review other person’s work.

Productivity can also drop when novice–novice pairing is used without sufficient availability of a mentor to coach them. Although pair programmers may complete a task faster than a solo programmer, the total number of person-hours increases. A manager would have to balance faster completion of the work and reduced testing and debugging time against the higher cost of coding. The relative weight of these factors can vary by project and task. Learn how to make remote pair programming work, including best practices for remote pair programming, tools and styles. The most common skill combination is an expert programmer working with a less experienced person.

Nevertheless, an organization should keep in mind that this software development approach will require a higher budget. One reason for this is that it adds a social component to a traditionally solitary and isolated role. Also, professional pair programmers say that their confidence in their work goes up when they work side-by-side with another software developer. Also called “peer programming,” each person looks at the code the other member is writing or directly after it is written.
