A solution design document allows you to visualize how the project is linked up & how it will work for the client, it usually comprises of a series of diagrams and flowcharts,that show each relationship clearly.
1. In order to do that you would need to create a rough outline of what the project would look like, so that the tasks gets clearly defined.
2. Make sure that your documentation is clear & concise and that they can minimize questions that cause delays, assumptions that cause confusion, and errors that cause rework.
3. A Good solution design must tell the developer everything he is supposed to program or build right down to the module title font, hyperlinks, and navigation of all buttons or other click able objects.
