Whilst scientists are by default motivated by intellectual challenges linked to the area of their interest rather than have an interest in the financial component related to their work, the reality of today is that funding for their work does not come automatically More and more governments provide project-related funding rather than multipurpose funding that covers the total annual costs of a research performing entity (such as a university department). So, like it or not, researchers have to present their research ideas and convince funding bodies about the usefulness and importance of their intended research work. Writing the research proposal is not simply typing words and punctuation. It requires succinctly and clearly chronicling the facts, as well as crafting a convincing line of reasoning for funding the project. For the best result, both the logical, verbal left side of the brain and the intuitive, creative right side of the brain need to work as a team. This article covers the process of writing a proposal, from research idea to submission to the funding body. The key to good writing is linking the text into a logical project flow. Therefore, in the early stage of writing an RTD proposal, developing the chain of reasoning and creating a flow chart is recommended to get a clear overview of the entire project and to visualise how the many work packages are connected.
