Improving ethical behavior. There are a lot of challenges and opportunities today for managers to use Organizational behavior concepts. The critical issues for which Organization behavior offers solutions are: 1. The creation of a global village The world has truly become global village. As multinational companies develop operations world wide, as workers chase job opportunities across national borders, managers have to become capable of working with people from different cultures. 2.

So workforce diversity has important implications for management practice. 3.

Benchmarking Productivity in Nursing

...Benchmarking Productivity in Nursing is Useful Benchmarking is a quality improvement tool that determines who the best is, who sets the standard, and what the standard is. There are two main purposes for benchmarking. The first is to identify best practices to be applied in measuring and improving performance in an organization. The second purpose is to seek ways to improve the delivery of service through the efficient use of staff. For health care managers who are responsible for a variable expense cost center or department, maintaining appropriate levels of productivity is one of the greatest and ongoing challenges of the management process and requires constant research and advice regarding relevant productivity standards. Comparing one’s departmental operations with other successful operations of another organization is a useful source of benchmarking data and many health care managers depend on associates or outside consultants to provide data to assist in implementing new and effective strategies to improve staff productivity. There are three sources of productivity standards. The first source is internally developed historical standards where standards are based on past performances but do not provide information about relative efficiency. The second source is engineered standards where internal staff or outside consultants conduct a study of the work environment and define normal standards of productivity.

Deming's 4 Paradigms and 14 Points

...Affiliation Deming’s 14 points and Deming’s Paradigms The first point talks about one having a purpose towards improving their products and services ,aiming to stay in business and become competitive. In management, leaders should have missions to improve their services and be competitive. The second point says that leaders must have and adapt to the new philosophy. In managing effectively, leaders must learn their responsibilities to help in better management. In the third point, Deming asks the leaders to stop depending on inspection.

...maintain a staff that is skilled, experienced and satisfied in their jobs. Unfortunately, so much was required of each employee it didn’t seem worth it as salaries were low. As a result, people were leaving to other companies that could pay more for their hard labor. The budget cuts on the supply department made it difficult for standards and quality to be maintained, yet higher management was coming down on Ted’s because his department was not improving with production and its quality. •A narrative discussion pointing out the major problem Once the corporation began to cut funding from the supply department, quality went down which was to be expected as ted now had to purchase supplies of lower quality. Also, paying his staff less led to people resigning which forced others to have cover down on the labor for those empty positions. Ted budget was cut by 20 percent and he was still expected to maintain and keep improving numbers; In order for that to happen he needed to figure out ways to keep improving supply productivity. Additional issues involved miscommunication with the cost to purchase machinery for more efficient productivity in the maintenance department. For example, quotes were being made for new machinery cost estimate of 5.5 million dollars and the actual starting cost was 7.2 million dollars. Lastly, upper management was coming down on him for results and other departments were complaining about the supplies...

Preparing for an Interview

...Who is primarily responsible for productivity in an organization? List some factors that can affect productivity and some ways that productivity can be improved. Productivity is described as a measure of the effective use of resources, usually expressed as the ratio of output to input. This ratio can be computed for a single operation, a department, an organization, or even an entire country. In an organization, the operations manager is the one primary responsible to achieve productive use of an organization’s resources but I would argue that productivity is the responsibility of all within an organization since it only makes sense to have everyone pulling in the same direction for the organization to be as productive as possible. There are multiple factors that affect productivity. Among them are methods, capital and technology, quality, and management. Before starting the improvement process, an organization needs to develop productivity measures for all operations and look at the system as a whole to decide which operations are most critical. Developing methods for achieving productivity improvements can be done by soliciting ideas from workers, studying the competition and other firms to see how they have increased productivity and reexamining how work is done. Reasonable goals must be established for improvement. Considering the multiple factors that affect productivity, there are many steps that can be taken in order to improve it, both in the short term and...

Goods are tangible products which we can use, consume or otherwise have in our life. For example, cars, batteries, tables and everything which can be easily quantified by units of length, weight, volume. However, services are somewhat different products which are more intangible in nature. These products are usually ones which are rendered by human labor but also have some goods aspect to it.

What Is Strategy

...What is Strategy? – Michael E. Porter I. Operational effectiveness is not strategy So in the quest to beat competition managers focus on improving quality, speed and productivity all related to operational effectiveness. But in this way, they move further away from viable competitive positions which can only be achieved by an appropriate strategy. Positioning which was once the way to go about beating competition is now rejected, since its too static. Rivals can easily copy the market position and competitive advantage. However, that is not entirely true as hypercompetition is a self-inflicted wound. It is important to watch out for what your competitors are doing, but improving operational effectiveness alone is not enough, and that cannot be your only strategy. Operational effectiveness and strategy are both important for superior performance which is what a firm aims for. A company can beat rivals if it can stand out, establish a difference it can preserve. Basically a company can either provide greater value to customers or comparable value at low prices, or both. Delivering greater value means higher unit prices, greater efficiency means lower unit costs. Cost arises from performing activities and cost advantage comes from performing activities more efficiently than your competitors. This can be in the choice of the activity or how the activity is performed. So activities are what creates competitive advantage. Operational effectiveness means performing similar...
