By using examples from different areas, we highlight the various elements that are part of the planning, execution and use of the risk analysis method. What are the main challenges we face? What type of methods should we choose? How can we avoid scientific mistakes? The examples used are taken from, among others, the transport sector, the petroleum industry and ICT (Information and Communication Technology). For each example we define a decision-making problem, and show how the analyses can be used to provide adequate decision support.
