One of the things that was missing at that time was software. To run a hospital, you need computer software. Yes, if you do not have one software, it is very hard to run a hospital properly, and to do it manually, that is impossible. But we managed it in four, five months. How? Because the software industry is very well developed. There are off-the-shelf software programmes which you can pick and buy, and then you just have to design your operational processes to suit the software, to be in accordance with the software. So, that is one quick and easy option, and that was the option I did in the case of NUH; successfully opened. But if you want bells and whistles, then of course, you have to spend time developing, modifying, changing the software codes; so it cannot be an off-the-shelf solution. In the case of NUH, we started with off-the-shelf solution, settled in, got the priorities right. And then over time, we added in all the bells and whistles, and then we had a very sophisticated software when I left the hospital.
