Six sigma is a popular approach to drive out variability from processes using powerful statistical tools and techniques. Although originally introduced by Motorola in 1986 as a quality performance measurement, six sigma has evolved into a statistically oriented approach to process and product quality improvement. Many organisations have reported significant benefits as a result of six sigma project implementation, though not all are yet success stories. This paper reviews the literature related to the critical success factors for the effective implementation of six sigma projects in organisations.

Critical success factors for the successful implementation of six sigma projects in organisations

Very few construction companies and consulting firms in Australia measure their costs of quality. Consequently, it is difficult for them to prove that systems for preventing quality failures are cost-effective. Although the direct costs of a quality system can be quantified with some accuracy (salaries, costs of documentation, audits, etc.), the corresponding benefits are far more difficult to assess. Indeed quality failures have become an endemic feature of the procurement process in construction and invariably lead to time and cost overruns in projects. Thus, in order to improve the performance of projects it is necessary to identify the causes and costs rework. The research presented in this paper quantifies the causes, magnitude and costs of rework experienced in two construction projects that were procured using different contractual arrangements. The causes and costs of rework projects are analysed and discussed. The findings reveal that the cost of rework for the case study projects was 3.15% and 2...

Quantifying the causes and costs of rework in construction

Science, specific knowledge, and total quality management

Purpose – According to the literature, quality management consists of a set of components: critical factors, tools, techniques and practices. The purpose of this paper is: to identify the components of total quality management (TQM), in order to make them known to managers and thus facilitate successful quality management implementation, and to show the situation of 106 ISO 9000 certified firms concerning these components.Design/methodology/approach – In order to achieve this objective, a literature review and a survey based on 106 ISO 9000 certified firms in Spain were developed.Findings – The results reflect that certified firms must develop their people orientation 1and use techniques and tools to a higher extent in order to progress towards total quality.Originality/value – The value of the paper is point out which TQM components are important to successfully implement TQM and identify the situation of these components in ISO 9000 certified firms in a particular area.

Components of successful total quality management

Educational institutions like other organizations are realizing the significance of customer‐centered philosophies and are turning to approaches such as total quality management to help manage their businesses. This paper starts with the background theory and then outlines the results of a study conducted on students within selected educational institutions in India to obtain a student perspective of the quality of those institutions. The SERVQUAL methodology was applied to identify the gap between customer expectations and perceptions of the actual service received. The quality function deployment technique was then used to identify the set of minimum design characteristics/quality components that meet the requirements of student as customers of the educational system.
