Data Warehouse Architecture – Concept and Models

According to William Inmon, data warehouse is a subject-oriented, integrated, time-variant, and non-volatile collection of data in support of the management’s decision-making process. Data warehouse is a database containing data that usually represents the business history of an organization. This historical data is used for analysis that supports business decisions at many levels, from strategic planning to performance evaluation of a discrete organizational unit. It provides an effective integration of operational databases into an environment that enables strategic use of data. These technologies include relational and MDDB management systems, client/server architecture, meta-data modelling and repositories, graphical user interface and much more. The emergence of cross discipline domain such as knowledge management in finance, health and e-commerce have proved that vast amount of data need to be analyzed. The evolution of data in data warehouse can provide multiple dataset dimensions to solve various problems. Thus, critical decision making process of this dataset Continue reading

Objectives of Performance Appraisal

Performance appraisal may be defined as a structured formal interaction between a subordinate and supervisor, that usually takes the form of a periodic interview (annual or semi-annual), in which the work performance of the subordinate is examined and discussed, with a view to identifying weaknesses and strengths as well as opportunities for improvement and skills development. In many organizations – but not all – appraisal results are used, either directly or indirectly, to help determine reward outcomes. That is, the appraisal results are used to identify the better performing employees who should get the majority of available merit pay increases, bonuses, and promotions. By the same token, appraisal results are used to identify the poorer performers who may require some form of counseling, or in extreme cases, demotion, dismissal or decreases in pay. (Organizations need to be aware of laws in their country that might restrict their capacity to dismiss Continue reading

The Operational Approach to Management

Management is referred to as the science of using people and resources to achieve goals. Sometimes managers are involved in supervision and, therefore, management can further be interpreted as making sure people do their duties as assigned to them. This means that managers are mandated to ensure that productivity is realized in an organization. An operational approach is an approach that is borrowed from Bridgman’s work; this approach attempts to bring together the knowledge of management that is related to functions of management. The operational approach brings together management concepts, principles and techniques in the management practice. According to Koontz and Weihrich, management involves designing and maintaining a working environment where individuals or people working in groups achieve their objectives efficiently. This means that management cannot be successful without a strategic plan, proper coordination of activities and direction, as well as a reasonable control of decision-making processes; therefore, managers should be Continue reading

Team Cohesiveness in the Workplace

A team dedicated to working together through mutual understanding is a cohesive team. Individuals on a cohesive team usually do not feel that they are working for themselves but for the team as a whole, which is the result of working together. Cohesion can be developed through skills and competencies where managers and employees can be motivated to have a common goal. Cohesion can also be developed by having clear goals, organization and planning, individual contributions to team goals, and sharing behavioral norms and values. Another way cohesion can be built is by creating a sense of belonging and a shared vision to achieve these goals. Managers and employees can build team cohesiveness in the workplace by promoting an effective communication strategy that will be used to communicate the organizational goals and visions. People are not successful and effective in the workplace because they do not establish a cohesive team, and Continue reading

Difference Between Economies of Scale and Economies of Scope

Economies of Scale The term economies of scale refers to a situation where the cost of producing one unit of a good or service decreases as the volume of production increases. Economies of scale arise when the cost per unit falls as output increases. Economies of scale are the main advantage of increasing the scale of production. Alfred Marshall made a differentiating concepts of internal and external economies of scale. That is that when costs of input factors of production go down, it is a positive externality for all the firms in the market place, outside the control of any of the firms. Internal Economies of Scale Internal economies of scale relate to the lower unit costs a single firm can obtain by growing in size itself. This means that the internal economies are exclusively available to the expanding firm. Internal economies of scale may be classified under the following Continue reading
