The Capability Maturity Model (CMM) is a development model created in 1986 after a study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ad hoc practices, to formally defined steps, to ...
Six Sigma (6σ) is a set of techniques and tools for process improvement.It was introduced by American engineer Bill Smith while working at Motorola in 1986. [1] [2]Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes.
The CSI Construction Contract Administration Practice Guide (CCAPG) provides a detailed discussion of the process of successfully delivering a construction project, focused on the roles of the various participants in the process and their relationship to one as described by contractual requirements in standard construction contracts.
e. In software engineering and development, a software metric is a standard of measure of a degree to which a software system or process possesses some property. [1][2] Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonyms.
The Design Quality Indicator (DQI) is a toolkit to measure, evaluate and improve the design quality of buildings. Development of DQI was started in the United Kingdom by the Construction Industry Council (CIC) in 1999. [1] It was initiated in response to the success of Key Performance Indicators devised for assessing construction process issues ...
Statistical process control (SPC) or statistical quality control (SQC) is the application of statistical methods to monitor and control the quality of a production process. This helps to ensure that the process operates efficiently, producing more specification-conforming products with less waste scrap. SPC can be applied to any process where ...
The process capability index, or process capability ratio, is a statistical measure of process capability: the ability of an engineering process to produce an output within specification limits. [1] The concept of process capability only holds meaning for processes that are in a state of statistical control.
BREEAM New Construction is the BREEAM standard against which the sustainability of new, non-residential buildings in the UK is assessed. Developers and their project teams use the scheme at key stages in the design and procurement process to measure, evaluate, improve and reflect the performance of their buildings.
