Directory boards are a type of directional sign. They are often used outside or inside a building to help people identify the particular location of a business, person or room. If your company is located in a multi-use office building, the directory board may be your first impression with a visitor. Ideally, you want to be found easily and for the sign to be neat and pleasing to the eye. Additionally, an office tower that experiences a high turnover rate may prefer a directory board that can be easily updated in-house. Whereas a hospital, that has been built specifically with the spaces of each department in mind, can invest in a directory board with a more permanent design.
