...development for many companies. The implementation of programs such as Total Quality Management (TQM) and Six Sigma help companies increase production and quality control, evaluate employee performance, and receive customer feedback. The Internet is also a magnificent tool that allows businesses and customers to communicate and help improve the performance of the company. The goal of most companies is to provide products and services that meet the quality expectations of their customers. Programs such as Six Sigma and TQM are essential for companies to compete with one another. Meeting the standards of customers is critical for businesses to succeed, and companies must continually improve on their products and services to meet the increasing demand of consumers. “Quality is the most important aspect of products and services, and the basis for the purchase of consumers. It has been reported that the quality movement has one core idea, and that is, goods and services must achieve the highest attainable quality, or nothing else will do. Thus, the past decade or so has seen the rise of a philosophy aimed at maximizing organizational quality and understanding it” (Connor, 1997). While there are other considerations, such as price, delivery, and flexibility, quality is still of utmost importance. This paper will discuss the advantages and disadvantages of implementing such practices as Six Sigma and Total Quality Management. Is one more beneficial than the other is, or is it best to...

Quality Methodology

...For the past twenty years many quality improvement methodologies have been used, including international standardization 9000, Zero Effect, Six Sigma, Lean, Total Quality Management, Work-Out, Balanced Scorecard, Baldridge, Business Process Re-engineering, and Plan-Do-Check-Act. Team Orange initially discussed using Total Quality Management, also called TQM, as a methodology for success as it involves customers and stakeholders as well as requesting input from all employees as a means to constantly improve quality. However, given the fast pace of this project, TQM ultimately was rejected because it lacks structure and a means to measure outcomes (Antony, 2009). Six Sigma was discussed nest, and eventually selected this methodology for its project, based on the consensus that Six Sigma will support assurance to stakeholders concerning the quality of implementing a Cloud based infrastructure including the associated software as a service and content delivery network into the NewwDeal information technology portfolio. Six Sigma tools and practices will also support the timely delivery of the project, create value for its stakeholders, and promote continuous improvement (Antony, 2009). The rationale for the decision is further described in the paragraphs below. According to Fehlmann (2004): Applying Six Sigma to software development makes software projects transparent to both management and customers. Transparency requires an important cultural change.

...relationship with that good. When a good's price increases, the demand for its substitute will increase because consumers will go looking for a cheaper alternative. Conversely, when a good's price decreases, the demand for its substitute will decrease. For example, margarine is a substitute for butter because a consumer can meet similar needs by using margarine. So, when the price of butter rises, the demand for margarine will likely increase.

The following is an overview of how they work together. What is Six Sigma? Six Sigma is a statistically-based process that strengthens organizational capacity for ongoing process improvement. “Six Sigma” or “six standards of deviation” aims to reduce defects to a rate of 3.4 defects per million defect opportunities by identifying and eliminating causes of variation in business processes. In defining defects or errors, Six Sigma focuses on developing a clear understanding of customer requirements and is therefore very customer focused. The DMAIC Methodology. The Six Sigma process is based on a concept called DMAIC: • Define – clearly identify the problem, the requirements of the project and objectives of the project • Measure – to fully understand the current performance • Analyze – the measurements collected to determine and validate the root cause(s) • Improve – developing ideas to remove the root causes of variation and implement the solutions • Control – to establish standard measures to maintain performance and to correct problems as needed Motorola invented this...

Design/methodology/approach – A specific research question is: does learning mechanisms and continuous improvement practices support each other and how, and what type of learning can be identified in the improvement of business processes. The question is linked to one of the fundamental issues currently discussed in the field of organizational learning; how do organizations get “from here to there”, in other words, what is the dynamics of the processes of learning and how progressive learning is achieved. A case study of a few Finnish companies is made and a procedural implementation model is applied. Findings – The findings suggest that the learning process is characterized by measurement, detection and correction of errors, and cost reduction. In six sigma implementation, learning is a single-loop type of learning. It is an incremental change process which reminds a technical...
