What kinds of decision making situations may be analysed using PERT and CPM techniques?
CPM vs. PERTCPM or "Critical Path Method":tool to analyze project and determine duration, based on identification of "critical path" through an activity network. Knowledge of the critical path can permit management of the project to change duration. A single estimate for activity time was used that did not allow for variation in activity times Activity times are assumed to be known or predictable ("deterministic") Activities are represented as nodes or circles PERT or "Project Evaluation and Review Technique":Another derivative of the GANTT chartMultiple time estimates were used for each activity that allowed for variation in activity timesActivity times are assumed to be random, with assumed probability distribution ("probabilistic")Activities are represented by arrowed lines between the nodes or circles

Nature of management?
Computer Skills Technology changes so rapidly it is often difficult to keep up with the changes. It is necessary for managers to have computer skills in order to keep up with these rapid changes. Many of the processes that occur in offices, manufacturing plants, warehouses, and other work environments depend on computers and thus http://www.answers.com/topic/necessitate managers and workers who can skillfully use the technology. Although computers can cause headaches, at the same time they have simplified many of the tasks that are performed in the http://www.answers.com/topic/workplace. Time-Management Skills Because the typical manager is a very busy person, it is important that time be managed effectively. This requires an understanding of how to allocate time to different projects and activities. A manager's time is often interrupted by telephone calls, problems with workers, meetings, others who just want to visit, and other seemingly http://www.answers.com/topic/uncontrollable factors. It is up to the manager to learn how to manage time so that work can be completed most efficiently. Good time-management skills can be learned, but managers must be willing to http://www.answers.com/topic/prioritize activities, delegate, deal with interruptions, organize work, and perform other acts that will make them better managers. Technical Skills Different from computer skills, technical skills are more closely related to the tasks that are performed by workers. A manager must know what the workers who are being supervised are doing on their jobs or assistance cannot be provided to them. For example, a manager who is supervising accountants needs to know the accounting processes; a manager who is supervising a http://www.answers.com/topic/machinist must know how to operate the equipment; and a manager who supervises the construction of a home must know the sequence of operations and how to perform them. Management ThoughtThere are many views of management, or schools of management thought, that have evolved over the years. What follows is a brief discussion of some of the theories of management that have greatly affected how managers manage today. Classical Thought The classical school of management thought emerged throughout the late 1800s and early 1900s as a result of the Industrial Revolution. Since the beginning of time, managers have needed to know how to perform the functions discussed earlier. The Industrial Revolution emphasized the importance of better management as organizations grew larger and more complex. As industry developed, managers had to develop systems for controlling inventory, production, scheduling, and human resources. It was the managers who emerged during the Industrial Revolution, many who had backgrounds in engineering, who discovered that they needed organized methods in order to find solutions to problems in the workplace. Classical management theorists thought there was one way to solve management problems in the industrial organization. Generally, their theories assumed that people could make logical and rational decisions while trying to maximize personal gains from their work situations. The classical school of management is based on scientific management which has its roots in Henri Fayol's work in France and the ideas of German sociologist Max Weber. Scientific management is a type of management that bases standards upon facts. The facts are gathered by observation, experimentation, or sound reasoning. In the United States, scientific management was further developed by individuals such as Charles Babbage (1792-1871), Frederick W. Taylor (1856-1915), and Frank (1868-1924) and Lillian (1878-1972) Gilbreth. Behavioral Management Thought It was because the classical management theorists were so machine-oriented that the behavioralists began to develop their thinking. The behavioral managers began to view management from a social and psychological perspective. These managers were concerned about the well-being of the workers and wanted them to be treated as people, not a part of the machines. Some of the early behavioral theorists were Robert Owen (1771-1858), a British industrialist who was one of the first to promote management of human resources in an organization; Hugo Munsterberg(1863-1916), the father of industrial psychology; Walter Dill Scott (1869-1955), who believed that managers need to improve workers' attitudes and motivation in order to increase productivity; and Mary Parker Follett (1868-1933), who believed that a manager's influence should come naturally from his or her knowledge, skill, and leadership of others. In the behavioral management period, there was a human relations movement. Advocates of the human relations movement believed that if managers focused on employees rather than on http://www.answers.com/topic/mechanistic production, then workers would become more satisfied and thus more productive laborers. Human relations management supported the notion that managers should be paternalistic and nurturing in order to build work groups that could be productive and satisfied. The behavioral science movement was also an important part of the behavioral management school. Advocates of this movement stressed the need for scientific studies of the human element of organizations. This model for management emphasized the need for employees to grow and develop in order to maintain a high level of self-respect and remain productive workers. The earliest advocates of the behavioral science movement were Abraham Maslow (1908-1970), who developed Maslow's hierarchy of needs, and Douglas McGregor (1906-1964), who developed Theory X and Theory Y. These theories are discussed in depth in other articles. Contemporary Management Thought In more recent years, new management thoughts have emerged and influenced organizations. One of these is the sociotechnical system. A system is a set of http://www.answers.com/topic/complementary elements that function as a unit for a specific purpose. Systems theorists believe that all parts of the organization must be related and that managers from each part must work together for the benefit of the organization. Because of this relationship, what happens in one part of the organization influences and affects other parts of the organization.
What do you understand by bias in production and operation management?
Bias is a term used to describe a tendency or preference towards a particular perspective, ideology or result, when the tendency interferes with the ability to be impartial, unprejudiced, or objective.[1]. In other words, bias is generally seen as a 'one-sided' perspective. The term biased refers to a person or group who is judged to exhibit bias. It is used to describe an attitude, judgment, or behavior that is influenced by a prejudice. Bias can be unconscious or conscious in awareness. Having a bias is part of a normal development. Labeling someone as biased in some regard implies they need a greater or more flexible perspective in that area, or that they need to consider more deeply the context. In psychology, cognitive bias is bias based on factors related to the brain as an information processor. One type of cognitive bias is confirmation bias, the tendency to interpret new information in such a way that confirms one's prior beliefs, even to the extreme of denial, ignoring information that conflicts with one's prior beliefs. The fundamental attribution error, also known as "correspondence bias", is one example of such bias, in which people tend to explain others' behavior in terms of personality, whereas they tend to explain their own behavior in terms of the situation In statistics, there are several types of bias: Selection bias, where there is an error in choosing the individuals or groups to take part in a scientific study. It includes sampling bias, in which some members of the population are more likely to be included than others. Spectrum bias consists of evaluating the ability of a diagnostic test in a biased group of patients, which leads to an overestimate of the sensitivity and specificity of the test. The bias of an estimator is the difference between an estimator's expectation and the true value of the parameter being estimated. Omitted-variable bias is the bias that appears in estimates of parameters in a regression analysis when the assumed specification is incorrect, in that it omits an independent variable that should be in the model. In statistical hypothesis testing, a test is said to be unbiased when the probability of rejecting the null hypothesis exceeds the significance level when the alternative is true and is less than or equal to the significance level when the null hypothesis is true. Systematic bias or systemic bias are external influences that may affect the accuracy of statistical measurements.

The Binomial Test is a parametric statistical test?
Binomial is a non- parametric test. Since this binomial test of significance does not involve any parameter and therefore is non parametric in nature, the assumption that is made about the distribution in the parametric test is therefore not assumed in the binomial test of significance. In the binomial test of significance, it is assumed that the sample that has been drawn from some population is done by the process of random sampling. The sample on which the binomial test of significance is conducted by the researcher is therefore a random sample.
