What exactly are they doing up there you may well ask?
Well, to shed some light on the role that he and his team play, Rob Thirlby spoke to the matchday programme this week.
Rob has been involved with Gloucester Rugby in this role since the 2010-11 season.
This followed a distinguished playing career that saw him turn out for Saracens, Bath Rugby and Gloucester Rugby in the Premiership, as well as starring for England on the Sevens circuit.
He began by explaining what happens on a matchday.
"Basically, we're documenting all the events that take place during a game and putting some detail around that.
"That gives us some live performance information on ourselves that we can feedback to the coaches.
"We can also look at certain strengths and weaknesses of the opposition and pass that on as well to get messages on to the pitch. That can be about lineouts or strike plays for example.
"Thirdly, we'll collect some clips that we can highlight on the screens in the dressing room at half time."
The combination of technology and software, plus attention to detail on the part of the analysts during the game, means that key information can be relayed to the decision makers, on and off the pitch, as quickly as possible.
"It's pretty much instantaneous. We're inputting data as it happens which then gets converted into some pretty comprehensive spreadsheets. We can view any clip at any point and send that straight down to the bench."
In fact, one recent development has seen a MacBook Pro utilised down on the bench, by the likes of Alex Brown in order to analyse lineouts for example.
You'll spot it down there if you look carefully - if it's raining, it'll be safely covered up of course!
Key to the work that the work that Rob and the other analysts do, is the relationship with AT Computers in Tewkesbury.
Rob actually spent time working there before joining Gloucester Rugby full time and the relationship has gone from strength to strength.
"The laptops are kindly supplied by AT Computers and their expertise around the knowledge of the MacBooks and the software has been invaluable.
"They've helped us produce an efficient and reliable solution where we can produce instantaneous information at half time and full time on iPads.
"They're very much market leaders in this field. They sponsored the British Lions on their last tour of South Africa and do a lot of work with the Welsh Rugby Union.
"They supply all the hardware, infrastructure around the Macs and associated training while we get the software from a company called Sportstec in Australia. They're the industry standard really, there's not a professional team without SportsCode.
"So, we're in good hands, very lucky that they're based just up the road from us and fortunate to have a sponsorship deal with them."
It's not just about matchdays of course. Work carries on throughout the work as individual and team performances are broken down and opposition analysed.
"We obviously review the game as early on in the week as possible to try and get that out of the way. That can be attack, defence or individual analysis for the players.
"By Monday, myself and the other analysts will also already have previewed the opposition for the forthcoming game. We're always working a week in advance so we can supply everything the coaches need."
As with any line of work that involves technology, developments are rapid but Rob is confident that he's working with the right partners.
"Things do move on quickly and we're always trying to keep an ear to the ground to keep on top of what's going on. Sportstec work with lots of different sports and there's something to be learned from that for example.
"And, of course, on the technology front, there are always new developments. Who would have thought a few years ago, we'd be using iPads on the touchline?
"Fortunately, we've got AT keeping their finger on the pulse on that score on our behalf."
