PRISM '4D' is a four-dimensional profiling instrument and comes complete with a 13-page workbook and a basic profile narrative. Quick and easy to use, it provides a great introduction to understanding human behaviour, thus allowing individuals to understand themselves and others better. Designed, primarily, for educational purposes, it provides a non-threatening introduction to important issues such as self-awareness, communication skills, inter-personal relationships and conflict awareness. Although it is of particular use for young people from 12 years of age upwards and ideal for use in schools and colleges, it also has business benefits such as enhancing communication skills in call centres.
