Crosby pointed out that the Six Sigma standard does not go far enough—customers deserve defect-free products every time. For example, under the Six Sigma standard, semiconductors, which require the flawless etching of millions of tiny circuits onto a single chip, are all defective. Role of consultants The […]

Courtesy: six sigma black belt Six Sigma mostly finds application in large organizations. According to industry consultants like Thomas Pyzdek and John Kullmann, companies with fewer than 500 employees are less suited to Six Sigma or need to adapt the standard approach to making it work for them. Six Sigma, however, contains a large number of tools and […]

DMAIC DMAIC’s five steps The DMAIC project methodology has five phases: Some organizations add a Recognize step at the beginning, which is to recognize the right problem to work on, thus yielding an RDMAIC methodology.

Courtesy: Six sigma Black belt 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. Six Sigma strategies seek to improve manufacturing quality by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. This is done by using empirical and statistical quality management methods […]
courtesy : eco-tour INFORMATION Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people.[1] Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures […]
Courtesy: Risk Assessment service Software evolution Studies have shown that early parts of the system development cycle such as requirements and design specifications are especially prone to error. This effect is particularly notorious in projects involving multiple stakeholders with different points of view. Evolutionary software processes offer an iterative approach to requirement engineering to alleviate the problems of uncertainty, […]

Health risk assessment can be mostly qualitative or can include statistical estimates of probabilities for specific populations. In most countries, the […]

It is commonly prepared by decomposing plant, food waste, recycling organic materials and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes and fungi. Compost improves soil fertility […]
Courtesy: Risk Assessment service Small sub-populations When risks apply mainly to small sub-populations, it can be difficult to determine when intervention is necessary. For example, there may be a risk that is very low for everyone, other than 0.1% of the population. It is necessary to determine whether this 0.1% is represented by: If the […]
Courtesy: Risk Assessment service Dynamic risk assessment During an emergency response, the situation and hazards are often inherently less predictable than for planned activities (non-linear). In general, if the situation and hazards are predictable (linear), standard operating procedures should deal with them adequately. In some emergencies, this may also hold true, with the preparation and […]
