Writing research proposals is an integral, although perhaps the least favorite, part of doing science. In an academic environment, the financial resources for carrying out the research come, to a large extent, from external sources. Similarly, in an industrial environment, research proposals are often the means by which a researcher must convey to management the value of supporting a project. Proposals thus are essential for securing research funding, but they are important for other reasons as well. Having research proposals funded shows that your research stands up to peer review, that it has the qualities judged worthy of receiving financial support, and that you are able to communicate research plans in a compelling way. It thus constitutes a sign of professional expertise in job applications and often is considered of critical importance in decisions regarding tenure and promotion. Research grants can sometimes be transferred along with the individual when switching to a new university. Bringing in already-existing research funds can positively influence the decision to make a job offer to the holder of those grants. Research grants thus not only provide the financial means to carry out research, they increase the market value of scientists applying for a job or seeking tenure or promotion.
