Abstract

The “PQ” problem was published in 1990 by Goldratt. An adapted version of this problem is provided to master’s level students a few weeks before starting an operations management course. The performance statistics collected from three South African (since 2016) and one European business school (from 2018 onwards) do not make for good reading. To date, only 2.3 per cent of the students (42 students from the sample of 1 866 students) were able to answer both questions correctly; and some of them were not able to justify their correct decisions. This paper will explore the differences between traditional, cost-based methods of decision-making for day-to-day operational and improvement decisions as practised by many companies today — and hence the bad performance by the students — and taking a systems approach to decision-making. The paper will argue for taking the systems approach as a real alternative, without which alternative realities will remain but a dream.

Die “PQ” probleem is in 1990 deur Goldratt gepubliseer. ’n Aangepaste weergawe van hierdie probleem word aan meestervlak studente gegee ʼn paar weke voor die aanvang van ʼn kursus in operasionele bestuur. Die prestasie-statistiek ingesamel by drie Suid-Afrikaanse (sedert 2016) en een Europese besigheidskool (sedert 2018) is onrusbarend swak. Tot op hede, was slegs 2.3 persent van die studente (42 studente uit die steekproef van 1866 studente) in staat om beide vrae korrek te beantwoord, en van hulle was nie in staat om hulle korrekte antwoorde te verduidelik nie. Hierdie artikel ondersoek die verskille tussen tradisionele, koste-gebaseerde metodes van besluitneming vir dag-tot-dag operasionele- en verbeteringsbesluite soos deur verskeie ondernemings vandag gebruik word — en daarom die swak studenteprestasie — en ’n stelselbenadering tot besluitneming. Hierdie artikel voer aan dat ʼn stelselbenadering ʼn werklike alternatief is tot besluitneming, waarsonder alternatiewe werklikhede bloot ʼn droom sal bly.
