Literature Review


This appendix provides some more background to quality management methodologies used across industries and introduces some of the UK industry initiatives to help reduce error and rework in construction industry. A.1.1 – Methodological approaches to quality management Plan – Do – Check – Act (or adjust).

At its most fundamental, the quality enhancement process can be described as an iterative four stage process, sometimes known as the Deming cycle. The four stages: Plan; Do; Check; Adjust (or Act) – PDCA – are necessary for continuous improvement in many of the following methodologies.

Each methodology represents an implementation of the PDCA approach but will focus on either the whole or part of the process. Further, the levels of sophistication of implementation may vary, some approaches use statistical approaches to understand deviations, others may require more subjective.
