'Pair Development' is not so much a specific technique to pair, but Goal is to be able to easily switch roles after some time, and ease Knowledge transfer, but shouldn't be overused. Useful onboarding tool to favor active 'learning by doing' over While this technique borders on micro-management, it can be a Where one person is a total novice, this can make the pairing much Should be discussed after the implementation session.

Each 'Pong' can also be followed by refactoring the code together,īefore you move on to the next failing test.

Developer B then starts the next 'Ping', i.e.

'Pong': Developer B writes the implementation to make it pass.

This technique embraces Test-Driven Development (TDD)Īnd is perfect when you have a clearly defined task that can be Notes and discuss them after the tiny goal is done, so as not to Park next steps, potential obstacles and ideas on sticky

As navigator, avoid the 'tactical' mode of thinking, leave theĭetails of the coding to the driver - your job is to take a step backĪnd complement your pair's more tactical mode with medium-term.

What the goals of pair programming are, and how to deal with the challenges It's for readers who are looking to get started with pairing, Pair', gives an overview of different practical approaches to pair They clarify ideas on the way, discuss approaches and come Work on a task together, they do not only write code, they also plan and discuss It is a very collaborative way of working and involves a lot of communication. Pair programming essentially means that two people write code together on one machine. The book introduced agile software development practices to a wider Kent Beck described the term in his book 'Extreme Programming' in the lateġ990s. More years for pair programming to become a widespread term, when They took on the task of programming when the word 'program' was not even used yet,Īnd there were no role models or books to tell them how to do this - and theyĭecided that it would be a good idea to work in a pair. Jean Bartik was one of the ENIAC women, who are considered by many to be the very first programmers.

The best programs and designs are done by pairs, because you can criticiseĮach other, and find each others errors, and use the best ideas. Programming is vital for collaborative teamwork and high qualityīetty Snyder and I, from the beginning, were a pair. Simple as 'two people working at a single computer', so many dismiss it Obvious, it pays off more in the medium- and long-term. One reason for its varying acceptance is that its benefits are not immediately Many people who work in software development today have heard of the practice of pair programming, yet it still only has patchy adoption in the industry.
