Abstract

Purpose

Companies face the critical reliability problem of products due to the development of outsourcing. This study intends to provide some feasible solutions for a company to improve the reliability level of products.

Design/methodology/approach

The paper considers the reward and reliability decisions regarding a product made with two complementary components from two different suppliers: high-capable and low-capable. Two kinds of reliability improvement incentives (normal incentive and cost-sharing incentive) through which a manufacturer provides a reward and shares the reliability improvement cost with a supplier are discussed. As the Stackelberg leader, the manufacturer determines the strategy, while the suppliers are responsible for determining its reliability. Using a game-theoretic framework, four different contract scenarios are addressed. We develop analytical methods to better understand how the manufacturer decides the incentive mechanism to be used for the suppliers.

Findings

The results show that cost-sharing contracts do not always lead to a higher reliability level and more enormous profits. Setting a target reliability level is better for the manufacturer. The cost-sharing contract is beneficial for a high-capable supplier even though it does not directly participate in that kind of mechanism. A low-capable supplier gains more profit when the manufacturer provides incentive mechanisms that do not specify a target reliability level.

Originality/value

This paper investigates the reliability improvement mechanism used for complementary products and focuses on identifying the optimal decisions when demand is influenced by the gap between the product's failure rate and the standard failure rate.

Abstract

States that the time taken to deliver a product to the market determines a company’s success, and that research has shown that a delay of six months leads to 33 per cent of its potential profit being lost. Explores the existing method of assessing new product reliability, namely reliability demonstrating testing, and presents its numerous shortcomings and deficiencies. Analyses the results of performing reliability demonstration testing on eight products which support the viewpoint that it is no longer appropriate. Proposes a SURGE (stress unveiled reliability growth enhancement) process, leading to significant saving in development time and thereby time‐to‐market while providing a more reliable product and process. Places emphasis on the control of all of the development processes, design, manufacturing, and materials procurement and producing prototype units via the intended volume process. Performs monitoring by appropriate stress testing designed to precipitate all potential defects and involves testing beyond design specification. By correcting defects on the product, and ultimately on the processes which produced them, develops more reliable products. Concludes that the results of the SURGE process have led to a reduction in development times of 14 per cent while also reducing the time taken to ramp up to full volume production by 50 per cent.

Abstract

Reliability of a product is highly dependent on the process capability index of the manufacturing process. Discusses a mathematical modelling technique for deriving the relationship between the product reliability strength and the process capability requirement to meet the product reliability strength for different types of external stress/load distributions which the product undergoes in the actual working environment. Considers four cases of external stress distributions: normal, log‐normal, expotential and Weibull. These techniques can be applied effectively in industrial production plants while selecting machines with required process capability to meet the product reliability strength demand.

Abstract

Argues that in the coming years the present methods of demonstrating reliability will no longer be feasible and alternative methods must be found. Deals with building‐in reliability (BIR) and the necessity to change from the standard end‐of‐line‐measurement technique of life test to a more proactive in‐line approach, where reliability can be measured by process parameters and reaction time is immediate, resulting in a continuous flow of reliable product to the end user. This approach will not eliminate the use of end‐of‐line monitoring, but will reduce the amount which needs to be carried out. Suggests that it will only be done to demonstrate that processes are operating to certain maximum failure rates, where the online controls will in fact guarantee that the reliability is much greater than that being demonstrated. Examines the customers’ attitude towards reliability, and points out that sharing of data will be essential if the BIR approach is to be successful. Outllines two examples which demonstrate the effectiveness of a BIR program and explains how, if implemented, it can be used to prevent the manufacture of potentially unreliable product.

Abstract

Purpose

The purpose of this paper is to contribute a model that would facilitate the infusing of quality and reliability in new products by blending Six Sigma concept and new product development (NPD) process.

Design/methodology/approach

A model called QUARNEWSS (stands for QUA – quality, R – reliability, NEW – new product and SS – Six Sigma) was designed. QUARNEWSS blends four stages of NPD process with Six Sigma's DMAIC improvement methodology and belt-based training infrastructure. After designing, QUARNEWSS was adopted to infuse quality and reliability in a new product being developed at a compressed air treatment products manufacturing company.

Findings

The implementation experience indicated that QUARNEWSS could act as a vehicle for systematically infusing quality and reliability in new products.

Originality/value

The contribution of QUARNEWSS model through this paper is valuable on considering the fact that modern customers demand new products with high degree of quality and reliability.

Abstract

Purpose

The purpose of this paper is to provide a structured methodology for performing build‐in reliability (BIR) investigation during a new product development cycle.

Design/methodology/approach

The methodology in this paper represents an extension of the Quality Functional Deployment/House of Quality (QFD/HoQ) concepts to reliability studies. It is able to translate the reliability requisites of customers into functional requirements for the product in a structured manner based on a Failure Mode And Effect Analysis (FMEA). Besides, it then allows it to build a completely new operative tool, named House of Reliability (HoR), that enhances standard analyses, introducing the most significant correlations among failure modes. Using the results from HoR, a cost‐worth analysis can be easily performed, making it possible to analyse and to evaluate the economical consequences of a failure.

Findings

The paper finds that the application of the proposed approach allows users to identify and control the design requisites affecting reliability. The methodology enhances the reliability analysis introducing and managing the correlations among failure modes, splitting the severity into a detailed series of basic severity aspects, performing also cost/worth assessments.

Practical implications

It is shown that the methodology enables users to finely analyse failure modes by splitting severity according to the product typology and the importance of each Severity criterion according to laws or international standards. Moreover the methodology is able to consider the “domino effects” and so to estimate the impact of the correlation between the causes of failure. Finally a cost/worth analysis evaluates the economical consequences of a failure with respect to the incurred costs to improve the final reliability level of the product.

Originality/value

The paper proposes a completely new approach, robust, structured and useful in practice, for reliability analysis. The methodology, within an integrated approach, overcomes some of the largely known limits of standard FMECA: it takes into account multiple criteria, differently weighted, it analyses the product considering not only the direct consequence of a failure, but also the reaction chain originated by a starting failure.

Abstract

The quality performance of a firm is often assessed by the reliability of the firm’s equipment or machinery. Yet, reliability has not received the same attention as quality. Several organizations today function effectively because the machinery which provides the “system of operation” is highly dependable and reliable. In this paper, we develop a framework that establishes the link between quality, reliability, and maintainability. The aim of this framework is to get corporate attention to focus on reliability issues and also, to establish the link between reliability, company’s bottom line, and corporate survival. A greater focus on “total reliability management (TRM)” will help firms to improve their productivity and efficiency while reducing cost and increasing their competitiveness.

Abstract

Purpose

To provide a case study of a medium size New Zealand electronic equipment maker striving to compete globally with implementation of an integrated new product development process.

Design/methodology/approach

This is based on my work performed in this New Zealand company. Due to confidentiality, detailed information and the name of the company were to be omitted in this article.

Findings

In the course of this work, it was found that New Zealand has great potential in electronics sector. However, as New Zealand is a latecomer as an electronic equipment maker, it needs to produce products for a certain niche market instead of competing with low cost electronic producing countries. Therefore, the ability to produce unique product quickly with required quality and reliability is essential for New Zealand electronic companies.

Originality/value

This paper discussed how New Zealand being a country remote from the rest of the world is able to participate in producing electronic equipment. This paper discusses the innovativeness of the company in developing their own version of new product development process.
