This chapter presents the consistent structure; people must have a well-developed bid solution and a project framework. Once the structure of the bid is defined, the final stage is the presentation and choice of writing style. These things will have a major influence on the persuasiveness of the proposal. The bigger and more complex the proposal, the greater the importance of choosing the right structure. Various aspects of the structure will often be dictated by the client and your starting point must always be the instructions given in the Invitation to tender (ITT). A top-down approach means starting with the highest level section headings and breaking these down into subsections via several passes through the document. The top level may be specified in the ITT or with organization's generic proposal structure. Sometimes, important parts of the solution are missed out in the top-down decomposition. To counter this, people can add to the structure bottom-up.
