IIT scientific activity is based on a 3-year strategic plan. The strategic plan is proposed by the Scientific Director and a panel of IIT senior scientists and is approved by the Scientific Technical Committee (STC), the Executive Committee and the Board of the Foundation. The Strategic Plan is periodically updated under the supervision of the STC. The current strategic plan (2015-2017) consists of 11 research Programs. Each program is developed by a number of fully independent Principal Investigators (PIs). PIs and their teams, distributed in 11 centers in Italy and 2 outstations in the US, develop their Research Line and contribute to one or more Programs, according to a Research Matrix of the Institute. An example of the research organization matrix is displayed below.
