Director of Projects:'How's the installation of the first of the luggage delivery systems going at Skipton Airport? I hope to hear good news. You know that we're still three weeks behind schedule. If we're going to meet the deadline we're going to have to knuckle down, to work harder and longer.'
Project Manager:'Well, we've run into a few problems I'm afraid. As you know we've already installed the first of the conveyor belts to carry the passengers' luggage and there have been some problems.'
Director of Projects:'In what way?'
Project Manager:'In two ways. During the first week of testing, the conveyor belt broke down three times. Each time we had to replace a number of parts in order to make it work again. But we have figured out what was causing the problem. There was a faulty cable and since we replaced it, it hasn't broken down since.'
Director of Projects:'So that's been sorted out and it's working fine now, good. And the second problem?'
Project Manager:'The second problem is with the delivery rate for the luggage delivery system. When we were designing it, we figured on each of the conveyor belts would move 50 bags per minute, but now the client is saying that he wants 100 bags to be moved by it per minute. Although it does seem easy to simply increase the speed of the system, the whole system is only designed to move a maximum of 90 bags per minute.'
Director of Projects:'How did you find out about them now wanting 100 bags per minute? The client agreed in the contract to a maximum of between 70-80 bags per minute.'
Project Manager:'The airport manager told us that they want 100 bags per minute when he came to look at the conveyor belt earlier this week.'
Director of Projects:'Can it be done?'
Project Manager:'Well, we've been looking into it over the last couple of days and we've come up with an idea which should mean that it can move 100 bags a minutes. We haven't tested it yet. Although we can rule out the possibility that this change will be a risk to any of the passengers or operators who use the system - we've installed luggage delivery systems at other places with a similar velocity without any problems, we can't exclude the possibility that if we implement this idea, it won't damage the machinery and cause the system to frequently break down. The machinery wasn't designed for that velocity.'
Director of Projects:'Before you go ahead with doing the testing, I have to speak with the client. So, can you hold off doing anything for the moment. It's best to wait before we do anything. I'm going to tell her what you've told me. I'll try to speak to her this afternoon and let you know what the outcome of it is.'
