The Hartz concept, also known as Hartz reforms or the Hartz plan, is a set of recommendations submitted by a commission on reforms to the German labour market in 2002. Named after the head of the commission, Peter Hartz, these recommendations went on to become part of the German government's Agenda 2010 series of reforms, known as Hartz I – Hartz IV. The committee devised thirteen "innovation modules", which recommended changes to the German labour market system. These were then gradually put into practice: The measures of Hartz I – III were undertaken between January 1, 2003, and 2004, while Hartz IV was implemented on January 1, 2005.
The "Hartz Committee" was founded on February 22, 2002, by the federal government of Germany led then by Gerhard Schröder. Its official name was Kommission für moderne Dienstleistungen am Arbeitsmarkt (Committee for Modern Services in the Labour Market). The 15-member committee was chaired by Peter Hartz, then Volkswagen's personnel director.(Wikipedia)
