This article evaluates the influence that quality concepts and tools in a manufacturing environment may have on parameters possibly affecting the future design and development of products in the same company. It attempts to establish how quality results can be utilised to determine the level of quality control tools used, such as Quality Function Deployment and Concurrent Engineering, in a company that designs for manufacture. By establishing links from quality results and customer requirements, the research determines what critical quality tools are necessary to determine the capability to manufacture an item without the use of excessive planning resources. OPSOMMINGHierdie artikel evalueer die invloed van kwaliteitskonsepte en kwaliteitsgereedskap in 'n vervaardigingsomgewing ten einde die effek daarvan op toekomstige ontwerp en ontwikkeiling te bepaal. Die doel is om kwaliteitsresultate te gebruik om die gebruiksvlak van kwaliteitsbeheergereedskap soos bv "Quality Function Deployment" en "Concurrent Engineering" te bepaal in 'n maatskappy wat 'n ontwerpsfunksie vervul vir vervaardigingsdoeleindes. Deur hierdie verwantskap tussen kwaliteitsresultate en kliëntvereistes te ondersoek, word bepaal welke kritiese gereedskap benodig word om die kapasiteit van vervaardiging van 'n komponent te bepaal sonder die gebruik van 'n uitgebreide beplanningshulpbron. *This
An Enterprise Resource Planning (ERP) project estimation process often relies on experts of various backgrounds to contribute judgments based on their professional experience. Such expert judgments however may not be biasfree. De-biasing techniques therefore have been proposed in the software estimation literature to counter various problems of expert bias. Yet, most studies on de-biasing focus on systematic bias types such as bias due to interdependence, improper comparisons, presence of irrelevant information, and awareness of clients' expectations. Little has been done to address bias due to experts' memory. This is surprising, knowing that memory bias retrieval and encoding errors are likely to affect the estimation process outcome. This qualitative exploratory study investigates the memory bias situations encountered by ERP professionals, and the possible coping strategies to problems pertaining to those situations. Using interviews with 11 practitioners in a global ERP vendor's organization, we explicate how experts retrieve and encode stored memory, what kind of errors they experience along the way, and what correction techniques they were using. We found that both errors due to memory retrieval and due to memory encoding seemed to lead to project effort underestimation. We also found that the most common memory correction strategy was the use of mnemonics.
