 Have you ever encountered a complex decision-making process which was hindered by the lack of data and you did not know what exactly can be done? Have you ever wanted to use expert opinion in a more rigorous manner but did not actually know how? Have you ever wanted to use structured expert judgment but were not sure exactly how to apply it? Well, now is the time to get a complete hands-on experience for applying structured expert judgment. My name is Tina Nane and I am truly excited to embark with you on this initiating journey. During this course you will be able to focus on your own expert judgment study or choose from exciting and relevant topics. You will then design and carry out your own expert elicitation. You will find your experts and run the elicitation. Finally, you will analyze the expert data using one of the most rigorous methods of evaluating and aggregating expert opinion. That is the classical model. The classical model is also known as the Cooke's method or the Delft method. That is because it has been developed here at TU Delft by Roger Cooke. You might know that Dutch are famous for cycling. The bikes are everywhere so their number and shape are impressive. Since cycling is a symbol of Dutch culture, the classical model is nicely represented using this adapted tandem bike. I invite you for a ride of this cool bike. During the course you will receive extensive guidance and feedback from the instructors to follow the appropriate steps for riding this bike. That is for conducting the expert elicitation. You will receive materials which you can use in any future elicitation. You will learn about the do's and don'ts of a structured expert judgment elicitation and benefit from the experience of the course team. Enjoy the ride!
