USING GAME AND STATISTICAL ANALYSIS TO CONFIRM GOLDRATT’S LOGICAL ANALYSIS OF POOR DELIVERY IN A MULTI-PROJECT ENVIRONMENT

ENGLISH ABSTRACT: The objective of this study is to confirm Goldratt’s logical analysis of poor delivery in a multi-project environment. Two hundred and ten experienced managers were invited to participate in a multi-project management game that simulates reality. A statistical analysis of the experimental data of this study indicates that the mode of project planning and execution (unrealistic project planning, a lack of clear working priorities, misuse of safety time, and bad multi-tasking), not uncertainty, is the root cause of poor delivery, and should therefore be improved first. The result confirmed Goldratt’s logical analysis of poor delivery in project management. AFRIKAANSE OPSOMMING: Die doel van die studie is om Goldratt se logiese analise van swak dienslewering in ‘n multiprojekomgewing te bevestig. Tweehonderd-en-tien ervare bestuurders is genooi om deel te neem aan ‘n multiprojekbestuurspel wat die werklikheid naboots. ‘n Statistiese analise van die eksperimentele data van die studie toon dat die metode van projekbeplanning en – uitvoering (onrealistiese beplanning, onduidelike prioriteite, misbruik van veiligheidstyd en swak multibetaking), en nie onsekerheid nie, die hoofoorsaak is van swak dienslewering, en moet daarom eerste aangespreek word. Die uitslag bevestig Goldratt se logiese analise van swak dienslewering by projekbestuur.
