T-shaped Skills definition
T-shaped skills describe specific attributes of desirable workers. The vertical bar of the T refers to expert knowledge and experience in a particular area, while the top of the T refers to an ability to collaborate with experts in other disciplines and a willingness to use the knowledge gained from this collaboration. A t-shaped person is someone with t-shaped skills.
The concept of T-shaped skills was described by David Guest in 1991, but was popularised by Tim Brown, CEO of design firm IDEO, when describing the type of people he wanted to work for his organisation.
