Control by quality: proposition of a typology

Abstract

Abstract.The application of Quality tools and methods in the industrial management had always a fundamental impact on the control of production facilities. It influences on the behavior of concerned actors, while introducing the required notions and formalisations, in particular in production systems little automated or not, that constitute a large industria l activity part.Several Quality approaches followed each other in workshops, and thus find again in their control. In this paper, the authors present a typology of different approaches having had some successive and notorious influences on workshop's control, as the statistical process control, the quality assurance and the continuous improvement.At first, the authors propose a parallel between production control and quality organization. They note a hierarchical organization of these two systems of management, with, to each level, the notion of feedback loop. This notion is fundamental in all decision making. They also organize their subject around the operational, tactical and strategic levels, by describing for each level the main methods and tools for control by quality.This panorama of tools and usable methods for the control starts by the operational level, with the SPC, Taguchi techniques or the ' six sigma' approach. At the tactical level, we recover a quality system approach, with a documented description of introduced procedures in the enterprise. The management system can refer here to the assurance quality, to the TPM or to a management by the total quality. The formalization using procedures of decision rules governing the control of processes brings a better validity of these rules. It allows to improve the reliability of these rules and to consolidate them. Thus it opposes the human behavior intrinsically fluctuating of operators' control. Finally, the strategic control by quality is detailed, and then the two main approaches, by continuous improvement and by proactive improvement, are exposed.To finish, the authors observe that to each of these three levels, the continuous improvement of processes which is a component of the Total Quality, becomes an essential preoccupation for the control. So, the idea which was coming out is the recursive utilization of the Deming cycle for control by quality.

Fundamentals of Quality Concept: Literature Review

“…Quality is found in all tangible and concrete forms of processes. Quality has also been a reflection of human civilization's progress in technology and science, an ever-growing demand from human society for better quality goods and services, and a resulting effort to satisfy customer demands (Mukhrejee 2019). Quality is associated with the whole environment around us, judged in terms of performance, parameters, and characteristics of the concerned product.…”

“…Thus, the quality process can be used in the different structural levels of the company with the objective of carrying out specific quality activities. In this sense, this process can shared at different levels : strategic, tactical and operational (Marcotte 1995), (Gentil et al 2001), (Pujo and Pillet 2002).…”

Quality improvement in maternal and newborn healthcare: lessons from programmes supported by the German development organisation in Africa and Asia

“…The Standards-Based Management and Recognition (SBM-R) approach used in Nepal’s EmONC mentoring programme aimed at improving the performance of medical, nursing and midwifery staff. Based on the Deming cycle of Plan-Do-Check-Act,25 the concept has been initially developed by Jhpiego in USA-supported programmes 26. In GIZ programmes, it was implemented in repeated cycles of four steps: (1) set healthcare performance standards for high quality of care; (2) put these standards into practice through capacity-building techniques; (3) measure performance before, during and after the programme; and (4) recognise and reward achievements.…”
