The Cost

Reducing the cost of quality in mass-housing projects can reduce the overall cost and can also result in increasing profitability or the possibility of getting more projects due to the lower price offered in the tenders. The first step to reduce the cost of quality is to identify different elements, determine their impact on the final product quality and then prioritize them. In this study, questionnaires and structured interviews with experienced construction professionals were employed to identify and prioritize the fundamental elements using the P-A-F (prevention, evaluation, and failure) method, one of the most well-known methods for categorizing quality costs. The results indicate a high impact of preventive activities and the low impact of external failure activities on final product quality. According to the results, the use of experienced specialists and skilled workers is more effective than in-service training of inexperienced forces. Corrective actions of non-conformities and design improvements have a significant impact on final product quality. The new approach to COQ elements ranking, used in this research, can help decision-makers to prioritize the most effective activities in construction projects to increase final quality with an optimum quality cost.

This study aims to examine the types of quality costs and their relationship with product productivity and quality in the companies. This research is a conceptual literature. Quality defines as customer satisfaction while productivity is the ratio between the outputs produced. This study shows the quality costs are directly related and have an impact on productivity, and product quality. Types of quality costs that are closely related to productivity and product quality are costs that arise with control activities including prevention and valuation costs. Cost of quality can produce high quality products ranging from increased productivity to the product will be produced and customer satisfaction is created. The cost of failure is inversely proportional to the cost of prevention and evaluation of quality and productivity. Companies can do this by reducing quality costs and improving quality for their customers with the most commonly applied methods with a classic prevention-assessment-failure (P-A-F) model or with other concepts and utilizing information technology.

Abstract The paper compares the cost of quality models in a different business unit of selected apple juice producers. Data and information were carried out through observation and interviews with key informants and related parties. Further data were analysed using the Activity Based Costing (ABC) approach to get a quality cost model for each business unit. The primary cost analysis shows a similar proportionality between the cost of prevention, appraisal, and cost of failure among three business units. Results illustrated that the higher the production capacity, the higher quality costs that occur or are budgeted for. From the calculation of quality costs, it is known that most of the quality costs come from appraisal costs. The cased business units indicated the high appraisal cost, which does have an impact on the low number of defective or failed products.

PurposeConstruction contractors in Palestine, as in many other developing countries, suffer from many problems. One of their main problems is their inability to meet contractual requirements, such as completing projects within time, at the agreed cost and to the desired quality. Therefore, this paper aims to investigate the causes of the non-fulfillment of contractual requirements in three different types of projects: building, road and electro-mechanical projects.Design/methodology/approachTwo methods were adopted to collect the data – qualitative and quantitative. In total, 65 causes were identified from the literature and qualitative semi-structured interviews with professional experts. These causes were classified into five categories: managerial, financial, contractor capabilities, regulations and laws and political. In the quantitative approach, a questionnaire was developed and then distributed to 50 professional experts: 20 building experts, 15 road experts and 15 experts in electro-mechanical projects. A five-point Likert scale was used to assess the importance, from the perspective of the subject matter experts, of the causes that had been identified. About 35 responses, which represent a combined response rate of 70%, were received. The quantitative data were analyzed using descriptive statistics, with the mean, standard deviation and degree of importance for each of the identified causes being determined, and the SPSS software platform used to rank them.FindingsThe results reveal that the most important reasons why contractors did not fulfill their contractual requirements in building projects were that contracts were awarded to the contractor offering the lowest price, and the profit margin was low because of intense competition among contractors. In road projects, the most important causes were the poor estimation of the equipment required and a lack of standardized conditions in the construction sector, while in electro-mechanical projects, the most important causes were the inability of the contractor to estimate the cost of the project accurately because of unclear bid documents and a lack of contractor capital.Originality/valueThe results of this study will be useful to stakeholders and Palestinian contractor unions. They can be disseminated to give guidance so that contractors can avoid these problems in future construction projects and enhance their compliance with contractual requirements. Moreover, knowing about these causes may lead to the reduction of conflicts and disputes between contractual parties (owners and contractors), which in turn will be reflected in the work quality and reputation of contractors.

Purpose The purpose of the study is to elicit risk factors that are peculiar to public-private partnership (PPP)-procured mass housing in Nigeria from the expert perspectives in ensuring the success of the scheme thereby reducing housing deficit in the country. Design/methodology/approach The risk inherent in construction projects had been established through literature in general. The risk in PPP projects is emerging because of the recent acceptance of the procurement option by governments all over the globe. The Nigerian Government has also adopted the procurement option in bridging the housing deficit in the country. This study, therefore, conducts a Delphi survey on the probability of risk occurrence peculiar to PPP mass housing projects (MHPs) in Nigeria. Pragmatic research approach through the mixed method of both quantitative and qualitative methods was adopted for this study. The quantitative method adopts the administration of questionnaires through the Delphi survey, whereas the qualitative method used interviews with the respondents. A two-stage Delphi questionnaire was administered to construction practitioners that cut across academics, the public and the private sectors by adopting convenient sampling techniques and following the Delphi principles and procedures. A total of 63 risk factors were submitted to the expert to rank on a Likert scale of 7 and any risk factors that the mean item score (MIS) falls below the grading scale of the five-point benchmark is deemed not necessary a risk factor associated with PPP MHPs and thereby expunged from the second round of the Delphi Survey. The interview was subsequently applied to the respondents to substantiate the risk factors that are peculiar to PPP-procured mass housing in the study area. Findings The findings show that risk factors such as maintenance frequent than expected, life of facility shorter than anticipated and maintenance cost higher than expected fall below 5.0 benchmark with MIS of 4.64 and 4.55 indicating that the risk factors are not peculiar to PPP mass housing in Nigeria. Research limitations/implications The implication for practise of this research is that these risk factors provide the PPP stakeholders with the comprehensive checklists that can aid in developing PPP risk assessment guidelines in the sector though both partners should be aware of the dynamic nature of risk because new ones might be emerging. Originality/value The authors hereby declare that the research findings are a product of a thorough research conducted in the study area and have not to be submitted or published by another person or publisher and due acknowledgement was made where necessary.

The PAF model, which is one of techniques about the cost of quality (CoQ), has been introduced to the head stack assembly process in the hard disk drive industry. Purpose to measure the total CoQ in the current process and use it as a tool to identify problems related to quality costs in order to find improvement plans. The total CoQ has been calculated in the percentage of the cost of quality per the cost of finished goods. Cost elements that impacted to the total CoQ have been prioritized and analyzed by using the Fish Bone diagram and the FMEA tool to find the potential causes of problems. The improvement plans have been implemented in order to reduce the chance of occurrences and improve detection ability. The result on two head stack models showed that the total CoQ could be reduced from 1.45% to 1.36% or 6.21% of improvement on the model A and reduced from 1.11% to 1.08% or 2.70% of improvement on the model B. The optimum points between the total CoQ and the quality level are 1.32% and 99.32% on the model A and 1.07% and 98.95% on the model B.

AbstractVery important in SMEs is to monitor cost of quality and economic indicators for valuation of cost effectiveness. The main goal of this article is to create classification on cost quality categories in SMEs and to analyze economic quality indicators and their trend during long period. In this article authors use economical and statistical indicators for costs of quality. We use common model PAF, that include prevention costs, evaluation costs, internal failure costs, external failure costs. Total costs, individual simple cost index, cost ratio and cost structure were used. We analyzed data from 50 small enterprises with 10-40 employees with their yearly turnover max 3 mil €. The research sample of enterprises was focused on industrial areas of business such as engineering, metallurgy, automotive industry. We analyzed the quality costs in SMEs by the average value of quality cost in all surveyed enterprises. Results of this research brought labeling of cost of quality in SMEs by model the PAF for 10 categories for various enterprises, what is very important for comparing of results of QMS in SMEs. Based on the reference indicators of the total costs of quality in SMEs we can conclude their drop. Reducing the costs of quality was reflected in particular in reducing the costs of internal and external errors. In assessing the economic efficiency in SMEs plays an important role the overall cost that were increasing in reporting period. Very important result is that the cost of quality did not influenced overall cost. This fact is positive for competitiveness in SMEs because it shows a quality of production and product. Reducing of cost of quality brought improving of product quality; reduced customer’s complaints brought financial savings. The economic efficiency indicator shows a value above e > 1. It means that, despite rising cost enterprises generate revenues that are significantly higher than the input factors of production. Cost effectiveness helps to improve TQM performance.

Changing the expectations and needs of customers over time has strengthened the quality prospects for the client. The goal of the company's assets is to satisfy the customer, keep the client and protect customer loyalty. At present, it is considered that the qualification in the health sector, in particular, has a strategic priority in the success of the business and that quality management is a sustainable competitive advantage. Medical services are at the forefront of the services that people receive the most. For healthcare companies that perform these services, quality is expressed as a strategic tool used to create activities that will meet the client's needs, both current and future, and reduce costs with an effective cost control process. In this context, healthcare companies need to pay sufficient attention to the quality of their services to customers. Quality service offered to people has a significant cost that businesses have to endure. Healthcare enterprises want to know the cost of the services they want to achieve as a result of their activities. This cost is the result of activities carried out at the enterprise. This study explains the concept of quality and the importance of quality and includes the cost of quality. Then the costs for quality, included in the total cost in the hospital, are processed separately in Baku (Azerbaijan).

Quality care for clients should be the focus of a family planning and reproductive health program, but can programs afford it? There is no simple answer. The multiple dimensions of quality of care make it more difficult to identify and measure affordable improvements in service delivery. Calculating program costs is challenging, and different methods can lead to widely varying estimates. Determining how much quality costs is a challenge, but it is both possible and important for programs’ sustainability. This brief focuses on various aspects of costs and examines information about the cost of improving quality (as opposed to the cost of quality of care in general), then outlines ways to improve quality while containing costs. Ideally, decisions about quality should be the result of a dialogue among policymakers, providers, and clients. Each program has to decide what standard of quality is appropriate to apply considering its situation, its resources, and the needs of the population it is meant to serve. This policy brief uses the framework developed by the U.S. Agency for International Development’s Maximizing Access and Quality initiative.
