A scriptorium was a necessary adjunct to a library; wherever there was a library it can ordinarily be assumed that there was a scriptorium.he Benedictine Plan of St. Gall is a sketch of an idealised monastery dating from 819-826, which shows the scriptorium and library attached the northeast corner of the main body of the church; this is not reflected by the evidence of surviving monasteries.
One of the most influential ideas about this was the notion of zero defects.. This phrase was coined by Philip Crosby in his 1979 book titled, Quality is Free.. His position was that where there are zero defects, there are no costs associated with issues of poor quality; and hence, quality becomes free.
But a zero defects policy does not provide this motivation to suppliers. When the goal of zero defects is applied to multiple interim points along the supply chain, the undesired effects of increased costs and lower yields are encouraged. The increased costs come from increased tests, inspections and cycle time.
