14, No. 4, December 1967 ) by referring to " a recent seminar " by Professor Horst Rittel, and discussing the moral responsibility of Operations Research " to inform the manager in what respect our ' solutions ' have failed to tame his wicked problems ".

Horst Rittel and Melvin M. Webber formally described the concept of wicked problems in a 1973 treatise, contrasting " wicked " problems with relatively " tame ," soluble problems in mathematics, chess, or puzzle solving.

The first nucleus of the band was formed under the name Snakebite in Düsseldorf, West Germany in 1980, and comprised Doro Pesch on vocals, Michael Bastian on guitar, Frank Rittel on bass and Thomas Franke on drums, the latter coming from the band Stallion.

Frank Rittel joined Warlock on bass before they started recording their debut album Burning the Witches in 1984, with producer Axel Thubeauville, a talent scout of German heavy metal groups.

Later that year, in the middle of the tour for Hellbound, guitarist Rudy Graf, who had developed a drinking problem, left the band and was replaced by Niko Arvanitis, a former band mate of Rittel in Stormwind.

At the same time, Szigeti and Rittel decided to leave the band, apparently unwilling to face the commitment that a transfer to the United States would involve.

Frank Rittel, Peter Szigeti and former Snakebite drummer Thomas Franke played in 1987 on Animal House, the first solo album by the former Accept singer Udo Dirkschneider.

Rittel and Szigeti formed in the 1990s the melodic metal bands Energy and Coracko, without much success.

Frank Rittel quit playing bass and retired definitely from the music business in 2004.

Rittel and Webber coined the term in the context of problems of social policy, an arena in which a purely scientific-rational approach cannot be applied because of the lack of a clear problem definition and differing perspectives of stakeholders.

Although Rittel and Webber framed the concept in terms of social policy and planning, wicked problems occur in any domain involving stakeholders with differing perspectives.

Recognising this, Rittel and Kunz developed a technique called Issue-Based Information System ( IBIS ), which facilitates documentation of the rationale behind a group decision in an objective manner.
