Abstract
Purpose
The purpose of this paper is to describe a novel methodology for predicting reliability for consumer electronics or any other hardware systems that experience a complex lifecycle environmental profile.
Design/methodology/approach
This Physics-of-Failure–based three-step methodology can be used to predict the degradation rate of a population using a Monte Carlo approach. The three steps include: using an empirical equation describing the degradation of a performance metric, a degradation consistency condition and a technique to account for cumulative degradation across multiple life-cycle stress conditions (e.g. temperature, voltage, mechanical load, etc.).
Findings
Two case studies are provided to illustrate the methodology including one related to repeated touch-load induced artifacts for displays.
Originality/value
This novel methodology can be applied to a wide range of applications from mechanical systems to electrical circuits. The results can be fed into the several stages of engineering validation to speed up product qualification.

Abstract
Purpose
Reliability capability is a measure of the practices within an organization that contributes to the reliability of the final product and the effectiveness of these practices in meeting the reliability requirements of customers. The purpose of this paper is to propose a model for evaluating the reliability capability of electronics manufacturers.
Design/methodology/approach
A survey methodology and statistical methods based on multivariate correlational analysis were used to validate the model theoretically.
Findings
The result of the analysis is a list and ranking of tasks that are critical to the development of reliable electronics products.
Originality/value
The paper presents a generic model for evaluating both in‐house reliability practices and those of suppliers to identify areas for improvement and for evaluating improvements over time.

Abstract
Purpose
This paper seeks to introduce a set of key practices that can be used to assess whether an organization has the ability to design, develop and manufacture reliable electronic products.
Design/methodology/approach
The ability to design, develop and manufacture reliable electronic products is defined in the paper in terms of a reliability capability maturity model, which is a measure of the practices within an organization that contribute to the reliability of the final product, and the effectiveness of these practices in meeting the reliability requirements of customers.
Findings
The paper presents a procedure for evaluating and benchmarking reliability capability. Criteria for assigning different capability maturity levels are presented. The paper also presents a case study corresponding to reliability capability benchmarking of an electronics company.
Originality/value
The paper provides a set of practices for evaluating and benchmarking reliability capability.
