The British public healthcare system has also been a major investor in MIS as it 1ries to control healthcare costs and simultaneously improve delivery standards .
Individual schools can also（）use ofMIS. Hobmoor Junior and Infant School， a public school in Birmingham， UK， introduced a computerised attendance system to produce MIS reports that monitor pupil attendance.
