Weight - the performance killer
Roland Whitehead, Quru CEO
Increasing costs are a real drag. Cash flow management can be thrown off kilter through unexpected technology costs, a prime example being ‘forced’ upgrades and license fees on proprietary software. Today, organisations are constantly looking to trim costs and increase their agility and speed of respond to changing market conditions. The same is true when designing a yacht and the search to reduce weight in order to increase acceleration. Hence, there is an intriguing relationship between how the fees you pay are financing Oracle Team USA and its search to reduce drag and yet are an increasing weight on your organisation. Maybe it’s time to do something about this!
Performance and weight
(and why Oracle is such a drag on your business)
If you could watch any of them during the development cycle you would very quickly notice that whilst they all want more power, better control, more reliability, they are simply fanatical about weight*.
The obvious place to start is looking at acceleration. Hopefully you picked up enough physics at school to know that:
|Force =||Weight x Acceleration|
Thus if you have a fixed force, doubling your weight will half your acceleration - it will take you twice as long to get up to the same speed.
Exactly the same thing happens when slowing down - the heavier you are, the longer it takes to slow down and so you have to start slowing down earlier in order to stop where you want. Now when you add up all the accelerations and decelerations around a race course, be it the world, Weymouth Bay or Silverstone, you can end up a long way behind the leaders if you are heavier than them.
Weight is the killer
Weight itself doesn't impact aerodynamic drag but it certainly affects road drag. The heavier the car, the more the tyre flattens and this consumes energy which slows you down. In addition, the heavier the car the more friction there is in the bearings which have to pass the weight of the car into the wheels and don't like running with extra weight.
Boats suffer three major forms of drag: aerodynamic drag; hydrodynamic skin friction drag; and wave drag. Again, weight doesn't really effect aerodynamic drag but the heavier the craft the more hull you have to have in the water. The more hull you have, the more surface area you have and hydrodynamic skin friction drag is almost directly proportional to the surface area. Wave drag is a function of speed, hull shape and weight but generally, the heavier the boat for a given length, the worse the wave drag is going to be; light boats don't make such big waves do they?
The America’s Cup
You've probably noticed that the America's Cup has finally woken up to performance sailing and realised that multihulls with wings produce much faster, more exciting sailing - and thus greater spectacle. It still staggers me that they took so long to catch on after Peter de Savary and Denis Conner showed them the way in 1988!
So, apart from being very brave, how have Oracle Team USA managed to do this? Quite simply they have thrown a staggering amount of money at it - money for the latest materials; money for the huge amounts of man hours employed so far.
Success comes at a cost
It’s at this point that I have to ask how, ultimately, has this incredible performance been achieved, i.e. where has all the money come from? The sad truth is that it has come from every company, every user who has licensed the Oracle database. The more money that Oracle Corporation makes, the more money finds its way into Larry's America's Cup fund and the more that is spent on saving weight.
"So," I hear you ask, "what's it got to do with me and what can I do about it?"
Well, we are all measured by performance and just as with a car or a boat, the issue of weight counts. Only with software, the weight is generally found in the cost. Your performance won't be that great if your costs are too high. Less cost produces a more nimble, faster accelerating business with less drag on the P&L. You don't have to improve Oracle Team USA’s performance at the expense of your own so take a look at something with excitingly similar abilities and a much lighter cost.
Roland Whitehead, Founder of Quru, spent many years designing race yachts, designing one Little America's Cup challenger and being involved with two America's Cup campaigns. He has been involved with software for motorsport teams, from stockcar racing to Formula One. Roland worked in more normal product design where one of his regrets is putting too much material in a plastic cat-flap thus giving a generation of cats a headache because they didn't open it fast enough. He has since been obsessed with removing weight where it isn't necessary.
* Yes, I know (as they all do) that it's not weight that counts but mass but since gravity is still constant at the speeds that all these designers and I were working at, I'll stick to calling it "weight" because you don't worry about your mass now do you?
