Sigma 10 20
What is the difference between a sigma lambda and particle neutral?
Both have the same composition of quarks, isospin projection same, same load, etc. The only difference is its mass. The neutral sigma decays very rapidly (10 ^ -20 s) in the lambda by EM interaction, but the defendant sigma no. My question is, basically, "why is there even a lambda particle at all"? It seems like an island, without real cause of its existence.
The sigma is a state of excitement, in which quarks are not in their ground state orbitals.

Six Sigma SERVQUAL
Introduction-History of Six Sigma and questions
Six Sigma is the application practical equivalent of a theoretical statistical measure of 3.4 defects per million opportunities, a position virtually zero defects in any process or of a service. Its success is a measure of high quality and is based on the ideology that almost all errors are preventable (Behar et al, 1994). Originally from Motorola Inc. in 1985 as a response to pressures to improve dramatically the quality of the threat of Japanese competition (Harry & Schroeder, 2000), has quickly gained many followers, including GE, Allied Signal, Ford Motor Company home etc and more recently have moved to the middle service.
Former CEO Bob Galvin of Motorola said that the lack of initial investment in sectors Non-manufacturing business for four years was a mistake that cost the company more than $ 5 million (Basu and write, 2003, p43). But organizations have implemented Six Sigma initiatives in the context of successfully compromises testimony of six wins in the Sigma range of services to American Express and PriceWaterhouseCoopers local service to the NHS.
The Nature of Six Sigma and quality objectives
As indicated and in Lagrán Lagrán (2003) six basic principles are the basis for quality management, as are common subjects for many quality awards recognized (Eg, Malcolm Baldridge Quality Award and the Swedish etc.) and form the basis of ideas presented by prominent authors in this field (eg, Dale, 1999, World Bank, 2000, etc..) The six core values –
1. Customer Orientation
2. Leadership Commitment
3. The participation of each
4. Continuous Improvement
5. Management by facts
6. Process Guidance
Six Sigma covers all these areas, and thus in a sense is not revolutionary, but focus on resource management and efforts to achieve the targets stated in a regulatory approach, it is clear and robust to implement in organizations. context search Objective indicates a strong positive relationship between setting challenging, measurable, specific goals and performance (White & Locke, 1981). Linderman et al (2001) argues that a key to the success of Six Sigma. The Six Sigma can succeed in a way I could TQM-TQM has not often been criticized for his weakness – "It is very difficult to motivate and justify what appears to be a circular route on several occasions where you really have is a spiral process that advances with each revolution, "said Tennant (2001, p. 35) regarding the clear objectives of the ACT.
The common goal in Six Sigma organizations is to reduce costs by eliminating defects (Greatbanks, Conferencia-18/11/03).
The costs of defects
What is claimed that Six Sigma must be implemented through the process that affect customer satisfaction and efficiency of the organization to reduce costs (Eckes, 2003, p3). The costs associated in following services:
• Lack Check default cost of service is detected by the customer and brought to the attention of server to be corrected, for example, a hair in the soup in a restaurant, the soup should be replaced.
• The difficult toll Nonverifyable to measure hidden costs have not been reported, for example, people rarely complain and request a refund if they attend a play badly.
Issues include the image in decline and goodwill, by the negative word of mouth and the costs associated with the recovery of a lost customer (3-5 times more expensive to attract a new one) without a loyal customer to a service organization would be economically very unstable.
· The costs of internal failure, the cost of correcting defects discovered by the producer before reaching the customer, overbooking rare example for a trip: the need for service to book two minibuses instead of one.
"Often, internal failures result of higher turnover and lower staff morale which in turn leads to recruitment and training costs above the cost of repairing the problem open.
(Al and Heskett 1990, p76)
Costs poor quality (COPQ) corresponds to sigma levels, for example, Six Sigma has been reached, the COPQ is less than 1% of the cost of sales when operates at three sigma levels, which many companies do COPQ equivalent to a level of about 25-30% of cost of sales (Basu and Wright, 2002, p39). This shows what a powerful tool for Six Sigma can reduce costs.
Six Sigma is very important for services that are found that the cost of quality in service organizations are larger in relation to the manufacture (Asher, 1987)
The Conservation Services
Services are notorious for waste, inefficiency and variability (George, 2003, p3), and as based service delivery man, then we can assume that a set clear objectives and change could motivate changes in the labor force. But other issues rooted in the nature of services in this context how Six Sigma can be implemented in this context.
Six Sigma was originally developed as part of the manufacturer. Above all, the services are of a different kind of physical products in the following concerns:
Lovebirds – Client participates in the actual process of production, the service is delivered and consumed simultaneously.
Forfeiture – Being intangible, the service can not be stored.
Heterogeneity – the difficulties in standardization services both for each client.
(Al and Ghobadi, 1994)
Quality Service
Quality is an important issue in services because of the characteristics of indivisibility, the intangibility and perishability. It can not be stored and intangible can not be checked for defects before the "delivery" to customers. In addition, each person involved in the process of change brings different levels of expectations and satisfaction levels, in addition to the unpredictable nature of human beings. It is the dominant role of human interaction in services that customer expectations shape and create difficulties in understanding and implementation of quality initiatives (Behar and Gundersen (2001)).
The most commonly used definition of quality is the extent to which the goods or services meet or exceed customer expectations (Zeithaml, 1981). Customer satisfaction should lead to repeated use of the service, if "zero defect objectives of production" are then "zero abandonment "should be a sign of quality comes to services (Reichheld and Sasser, 1990). Thus, for the definition phase of the methodology Six Sigma-related fields to optimize customer satisfaction should be focused on. However, it should be noted that feat in itself can be a source of confusing and complicated.
Six Sigma is the total satisfaction of customer services (Erwin, 2000).
As shown in Behar et al (1994, p12) Customer Satisfaction is a multistep process where satisfaction levels are multiplied as different facets of service are exposed to clients. These aspects include a wide range of ethical practices of the company to respond quickly to staff, etc. So, effectively, for example, whatever the cost, tasty hamburger at McDonald's is for a client who has moral problems with the low wages of their employees, compliance is not achieved. The key concept is that customers have different expectations, different models of the components involved and thus may have zero customer defection? Not everyone likes the same things and thinks the same way and therefore the service should focus on the elements that will please most of them only.
As services are intangible, there are greater problems for measuring quality, as we shall see, what constitutes quality may be different for different people based on their perceptions and experiences of past and what defines whether the defects in services? Often, this will be an obvious question of simply delivering what was promised, but in most cases, the dependence on customer feedback, complaints and measurement (as shown in the case study) will be used to illuminate the issues. Called Six Sigma by measuring such variables as the only way to better understand service gaps.
Service Implications
The use of quality programs in the relatively high in the service environment, for example, Robinson (2003) found that 90% of leisure and sports facilities managed by local authorities to implement a system of quality, however, indicates that the type of plan quality services is much less "technical" basis (for example, statistical process control, design of experiments, quality circles and patterns failure and effect analysis, FMEA) found in manufacturing and more in tune with "softer" cultural issues and the creation of an efficient and competent employees through the process (and Lagrán Lagrán, 2003). But Tennant (2001, P36) puts so eloquently, it is not the goal of Six Sigma Six Sigma tools and has the power to cut the ice where the hot air has contributed little in the past. "
The Six Sigma methodology is based primarily on statistical analysis services traditionally have a minimum of data and review their techniques, so it can balance a primary impediment. Beyond many people are afraid of metrics and use to connect to services. Breyfogle (cited in Smith, www.qualitydigest.com ) explains: "They (services) do not appreciate the importance of creating significant measures that give an idea of how their business processes over time. This variability may cause a fire hazard as in the special case common. "Argues that only by using statistical control charts to allow services to focus on prevention rather respond to problems. monitoring process is the only way to move from hypothesizing subjective grounds of errors of fact and one principles of Six Sigma.
Is this fear justified measure? Many researchers have tackled the problem of application techniques statistical non-industrial environments, such as Deming (1987, CH7) gives a long list of measures in the services sector like or PAC can be applied. It is observed Oakland (1989, P226) that "data is data … if the numbers represent faults or billing errors, the information is relevant to the computer configuration, process variables, prices, quantities, discounts, customers, or supply points is not relevant techniques can still be used. The conclusion is that statistics can be transferred to services is rare, however, that problems and issues are documented in the literature (success stories only) this does not mean, by implication, but these problems do not exist (Wood, 1994). It often requires creativity and talent to apply statistical techniques to service in a way that makes true understanding of what reality through the digital representation.
Health Study Caso
(Kooy et al, 2002)
The following example is simplified and divided into DMAIC methodology common to illustrate how Six Sigma is achieved in services.
Background
VirtuaHealth In June 2001, an organization of four hospitals in New Jersey, United States, has assembled a team of internal employees, including frontline staff and a leader in Six Sigma (belt Black formed by GE Medical Systems) with the objective of ensuring safe and effective sense of anticoagulation.
Project will focus on drug heparin (anticoagulant) used for the treatment and prevention of thromboembolic disease (blockages in the veins). Patients heparin within 24 hours of troubleshooting is a significant reduction of problems in the future, but there were also side effects involved to heparin therapy, including severe bleeding (thromboctopenia) and life or limb threatening thrombosis. Consequently, a weight based protocol was used to administer the right dose of medication.
DEFINE
The team identifies the customer (ie patients), the requirements and benefits of the process and prevent or treat anemia and thromboctopenia during treatment.
Both attributes are defined as follows-
Anemia, hemoglobin decrease in the rate at 1g/dL least a day (and the final value of less than 12 g / dl)
decrease in thrombocytopenia-50% of the number of platelet (blood clot allows) or a head under 100,000.
– The emergence of these attributes are considered outside the "therapeutic" Range.
acceptable practice was defined as the recognition of the reduction in monitoring and measures taken by the physician stopped treatment with heparin or other appropriate measures such.
MEASUREMENT
computerized pharmacy database manual used laboratory data to measure actual performance. Among the 815 patients who received therapeutic doses in the last 6 months, 18% were subtherapeutic and 35% were supra-therapeutic.
The team constructed a map of high-level process to to better understand the sequence of activities involved in the management and control of heparin (which is the component of service).
The median time between the administration of medication to control the outcome was 8.5hrs, which was considered later, but acceptable, however, was the amount of variation in the average time has been a source of problems. The samples during early preparation could lead medication adjustments based on the results of the unstable state, while those done too late could result in an unacceptable diffusion of the drug was administered.
ANALYZE
This phase is to identify factors that determine the outcome of the process. Obstacles to the success of each phase of the process was identified and a detailed process map has been developed (including laboratories and cycles in pharmacy), a total of 92 measures were identified to achieve the end of the adjustment dose first.
Many problems have been identified. stage has been completed down to remind staff to act, often hours after the activation of the event. We conclude that the complexity of the system is an obstacle to the implementation and had some elements of the system in place to help prevent problems. In particular, the first step with the protocol based on the weight was followed closely rare due to time constraints, only 48% of patients were weighed in all measures (precision critical medicines) and other patients for whom an estimated weight, 20% of estimates were given more than 10%. Finally, the progress of each step was broken and there was often uncertainty about who was responsible for the different stages.
In summary, Negative results are not due to minor variation process, but are related to major failures in domestic supply. The team concluded that, by simplifying the acute anticoagulation method of trial and error at each stage of this Act as the best prospect for extra security.
IMPROVE
At this stage, implementation and measurement of changes in the process towards the desired performance is considered. The weight problem has been overcome by investing in beds scales have been constructed, the hospital uses in other districts with great success for the weighing routine. This problem had been "flying under the radar" during the past several years and has been explained by the intervention of Six Sigma. In addition a record for weight management depending on the protocol of heparin notes that the responsibility (given by the doctor taking the case in exchange for a nurse), the measure again on time of 6:00. In addition, the new machine perfusion restrict the range of infusion based the weight calculation is performed to reduce the risk of overdose due to expiration of the nurses attention.
CONTROL
Visible metric "scorecards" (control charts, implementation diagrams, reports, etc.) are used by the project owner to ensure performance is maintained at an optimum level. The show will also feature on a monthly basis followed by a quality analyst Local in the department of quality control of hospitals. Discrepancies must be reported and discussed in detail by the quality and Pharmacy and Therapeutics.
Comment
An example of the public sector is used to show how Six Sigma methodologies can be extended to cover not primarily target the reduction of costs. defect reduction and reducing the costs are not mutually short term. Customer has been replaced by the patient and reduced cost for treatment success. Although not not explicit, the case study suggested that long-term costs would be reduced by a small amount of management time and fault-finding or compensation. Thus, all Six Sigma projects are reducing costs over the long term, but not always (and above) the reasons for the request (as in dealing with terminal illness).
The case study demonstrates the importance of measuring all the important inputs performance in order to analyze how a process can be improved. Six Sigma focuses on the opposition to the theoretical conjecture, but it is "management by facts, not emotion" (Randall, R. cited in Erwin, 2001, p38)
Conclusion
Influence of application "Six Sigma Services
Six Sigma is certainly more difficult to apply in a situation of services in the industry. Even when a process and the goal there is some might argue that setting the specification limits can be somewhat subjective subject, and sometimes organizations spend time and money by adding value to a specification where it is not appropriate (Breyfogle et al, 2001, P196). This can be remedied by applying an analysis of measurement systems (MSA), however, it should be noted that because these problems, the tasks of primary care services may take longer than expected because of the determination of appropriate measurement systems. (Breyfogle et al, 2001, P196).
However, this does not mean that Six Sigma not useful or too difficult to implement, the degree of use and the difficulty depends on the objectives of the company. The methodology can be used for rapid transport cost savings from the outset by the fact that fruit pieces rotating the Breyfogle "obvious problems hanging in an organization. At the opposite may also serve as a model for organizational culture "That every person at every level has a passion for continuous improvement in the ultimate goal of achieving virtual perfection "(Quoted in Basu and Wright, 2003, p3)
Decreased quality?
Some authors also support different types of service industry are not adapted to the rigid methodology avoid multiple facets that create satisfaction s own. There is often a compromise between customer satisfaction and effective management of a company. For example, a hair salon might lose customers if it simply tried to adapt haircuts as possible (assuming no decline in the quality of the haircut), the client in such circumstances than to be pampered at the hairdresser who take their time and a relaxed atmosphere to be accepted. Powell (1995) found that success depends more for intangibles, such as an open culture organization, training employees and managers in the commitment to measure the improvement process continuous improvement and benchmarking
This link also has the concept of reducing variability reduces defects and increase efficiency. Although primarily based on the quality of manufacturing, some services that route, for example, Machine "Have a nice day" script in the fast food chains, etc. It is important to note this will not lead to the satisfaction of customers these sectors.
Process or objective?
Behar et al (1995) argue that firms early US-1990 (Summary of all industries) ran around three or four sigma quality levels. The question is whether companies need to achieve Six Sigma level and it is in their interest to do so? At first you may think zero defects and total customer satisfaction is the end goal that all companies should strive to (even if it is for motivation), as transmitted by the principles of Crosby. However, understanding vision of traditional compromise between cost and prevention of failures in the service adds a different perspective. The concept is based on the premise that the costs of preventing error increases with the quality, in fact, the relationship is an exponential increase in the cost of prevention simply to improve the quality further. Thus, the goal of quality managers should strive to be less 100%, and the variables for the different departments of nature. (Heskett et al, 1990).
Six Sigma should not necessarily be achieved (Hammer & Goding, 2001) is limited to the methodology and understanding the optimal level of overall cost reduction must be understood and defined as the objective.
Fashion?
Among the literature, some authors have argued that Six Sigma is the latest fad, and it is a repackaging "of what has preceded (Dusharme www.qualitydigest.com .)
The challenge is to overcome the fatigue Six Sigma Innovation "(quoted in Basu and Wright, 2003), which may lead loss of interest in an initiative. It has been demonstrated by Turner (1993) that any quality initiative has to be reinvented at intervals regularly to maintain motivation levels of employees and the maintenance and implementation of a quality assurance program is about 2.5 years.
improvement initiatives often give up their initial success and gather the necessary momentum a permanent change in the actual organization of various hidden reasons. "Six Sigma is a quality approach that adopts a systematic approach to improve quality and customer service to improve the final result "(Basu and Wright, 2003, p 2) The main concept at this stage is the line" basic or restitution of assets, the key measure of success. This is a historic step that can account for the results after it is too late to influence it. In many cases it may be too late and formal periodic evaluations should be taken to allow flexibility necessary to meet the different stresses. The variable "control" in the DMAIC methodology must ensure the longevity and flexibility, and DMADV (Define, Measure, analyze, design, verify) methodology used to update and maintain the process as well. Thus, the question of whether Six Sigma is a fad or here to stay will be answered over time.
Alternatives and improvements
It is also worth mentioning how Six Sigma has expanded and developed to illustrate its evolution is the business and services in particular. Lean Six Sigma focuses on maximizing the speed of the process and provides tools to analyze the delay time and the process flow for activities (George, 2003). Its objective is to reduce waste in processes and procedures. Sigma Fit (Basu and Wright, 2003) adds an element of sustainability and does not focus on the perfect target of 3.4 defects per million, but whatever the "size" is for the organization.
Finally the man Sigma not so much on eliminating errors, and not on reducing the variance of key employees and customers of the results, assuming that the variance of large quantities of ineffective management. (Coffman, 2003). It seems that many modifications and variations of quality initiatives are being introduced by the fact that organizations, especially the services are different in structure, ethics, etc. goals, there seems to be a better fit " model and what is the situation of the company to choose one that best suits the best.
As discussed in this test, there are many issues that should be considered when evaluating the possibility of applying Six Sigma in services. They will how to define quality, indicating the cost of poor quality, implements technical statistics to monitor the situation, decide on the level sigma to be optimal for the operation including the service industry in these considerations, etc. While it is believed that Six Sigma is a useful tool in the service, Perhaps one reason that has been criticized is that people have become too literal interpretation
It offers businesses with a common metric that can be used throughout the organization and production to customer satisfaction. It also presents a with the possibility to compare results year after year with reference to rival firms and targets for enterprise development. Overall, more sigma represents fewer errors and customer satisfaction (Behar, 1994).
The facts are that in business is that they have results and in this sense Six Sigma has been a great success (Hammer & Goding, 2001)
