Abstract

Purpose

This paper seeks to document an approach to reduce scrap losses using the root cause analysis technique in a lean manufacturing environment.

Design/methodology/approach

The study uses lean manufacturing root cause problem solving (RCPS) technique. The study starts with the collection phase, followed by the analysis phase and ends with the solution phase. Supporting data are presented using a Pareto chart to prioritise wastage in order to be more focused for improvement. The Toyota Production System's 5‐whys analysis is performed to analyse the cause of wastages, to formulate and implement corrective actions.

Findings

The application of the 5‐whys analysis in a manufacturing industry (XYZ Corporation) provides a fact‐based and structured approach to problem identification and correction that not only reduces, but also totally eliminates defects. Corrective action has permanently eliminated the top defect, which is the “last piece material scratch” and this results in zero scrap thereafter. In this study it was also proven that with sound understanding of manufacturing coupled with possible solutions using the 5‐whys analysis the authors were not only able to eliminate waste, but also to do it with zero‐cost.

Originality/value

The approach documented in the paper can be extended to other areas in the manufacturing industry to help improve overall equipment efficiency, breakdown, time loss, customer complaints, etc.

Abstract

Purpose

The purpose of this paper is to examine the affordability of private tertiary education for households in Malaysia.

Design/methodology/approach

The relevant literature is reviewed to provide an overview of the affordability of private tertiary education. Data are obtained randomly from a private university in Malaysia and the results are analyzed using the one‐sample t‐test and one‐way ANOVA.

Findings

The proxy of affordability, which is the average household income, reveals the per capita average is more than three times the national average, which points out the non‐affordability of students from low and average earning households to afford private tertiary education in Malaysia. Financial assistance of students at the tertiary level is insufficient and may warrant further policy and administrative improvements to reach deserving students. There is also difference in income and hence affordability between urban‐rural households, a perspective that demands changes in the current income distribution policies. In order to address the issues highlighted in this study, salient suggestions have been proposed.

Originality/value

This paper reinforces the need to address the issue of affordability of tertiary education and its significant importance, especially to developing countries.
