Using the same word in different meanings in the design brief obscures the delivery. Separate the tasks of the concept, mockup, source file, and print file.
Separate application with concept
The concept is the basic visual or narrative idea of the work. The application may be the form of the idea adapted to a poster, screen, or packaging. It is not the same job to ask for three measures of a concept by asking for three concepts. Write clearly at what stage in the proposal to evaluate; word choice directly affects the workload.
Mockup is not a production file
Mockup is the presentation that shows how the design can look on an actual surface. It tells the idea because it contains perspective, light and texture; it does not replace the file to be sent to the printing press. The ready-to-print file is prepared according to the manufacturer's technical conditions. Note that technical rehearsal and text control are also required when approving the presentation visual.
Do not confuse high resolution with vector
Vector drawing consists of mathematical shapes, raster visual pixels. A large photo file is not a vector; the file extension does not guarantee that all elements within it are vectors. Talk to the manufacturer about what content is needed to grow the logo or use it in the cutting application. Saving an inappropriate file with a different extension does not solve the problem itself.
Explain the revised and new scope by example
Correcting the date on the selected poster may be revised; re-establishing the campaign based on the different target audience may require new coverage. Add two examples from your own project to the end of the Brief. So you not only define the concept, but show how to make the decision. Understandable terms provide less questions, more traceable approval, and more accurate delivery expectation.
