Many instructional designers design for the same target population over and over again. For example, you develop courses only for first line managers, or only for accountants. In these cases, consider a more detailed audience analysis that identifies a wider range of characteristics and preferences than you would normally complete.
If your whole department develops for the same audience over and over again, consider a detailed audience analysis study as a departmental project for all developers to use and periodically update. This will save time in the long run.
Don't forget, however, to check out the target audience's current knowledge and skills related to your specific topics on each new project.
