What does it mean? It means - -4 -00:00:08,390 --> 00:00:11,790 -that all production code is written with two people looking at one - -5 -00:00:11,790 --> 00:00:15,170 -machine. And not that they're, they're working with one keyboard and - -6 -00:00:15,170 --> 00:00:18,450 -one mouse or they're not just interfering and writing on each other's - -7 -00:00:18,450 --> 00:00:20,920 -code. And the way in which that happens is by playing - -8 -00:00:20,920 --> 00:00:25,180 -different roles at different times. So the two developers alternate between the - -9 -00:00:25,180 --> 00:00:29,080 -role of programming and strategizing, where strategizing means, for example, - -10 -00:00:29,080 --> 00:00:31,660 -looking at the code that has been written and thinking whether - -11 -00:00:31,660 --> 00:00:34,420 -that would work. Or what other tests that are not there - -12 -00:00:34,420 --> 00:00:37,050 -might not work, given the way the code is being written. - -13 -00:00:37,050 --> 00:00:39,300 -Or maybe looking at the code from a, you know, slightly - -14 -00:00:39,300 --> 00:00:42,380 -detached perspective and trying to figure out whether the code can - -15 -00:00:42,380 --> 00:00:46,900 -be made simpler, more maintainable, more efficient. And interestingly, there are - -16 -00:00:46,900 --> 00:00:48,440 -measurements, there are studies that - -17 -00:00:48,440 --> 00:00:50,340 -suggest that development productivity with pair - -18 -00:00:50,340 --> 00:00:52,550 -programming is similar to that of two people - -19 -00:00:52,550 --> 00:00:55,080 -working independently. And that answers one of the - -20 -00:00:55,080 --> 00:00:57,740 -main objections against pair programming, which is why - -21 -00:00:57,740 --> 00:00:59,840 -should I put two developers together, which is - -22 -00:00:59,840 --> 00:01:01,860 -going to cut their productivity in half.
