Work Sampling
Work sampling is the statistical technique used for determining the proportion of time spent by workers in various defined categories of activity (e.g. setting up a machine, assembling two parts, idle…etc.). It is as important as all other statistical techniques because it permits quick analysis, recognition, and enhancement of job responsibilities, tasks, performance competencies, and organizational work flows. Other names used for it are 'activity sampling', 'occurrence sampling', and 'ratio delay study'. In a work sampling study, a large number of observations are made of the workers over an extended period of time. For statistical accuracy, the observations must be taken at random times during the period of study, and the period must be representative of the types of activities performed by the subjects. One important usage of the work sampling technique is the determination of the standard time for a manual manufacturing task. Similar techniques for calculating the standard ...

Observation
Observation is the active acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to any data collected during the scientific activity. Observations can be qualitative, that is, only the absence or presence of a property is noted, or quantitative if a numerical value is attached to the observed phenomenon by counting or measuring. Science The scientific method requires observations of natural phenomena to formulate and test hypotheses. It consists of the following steps: # Ask a question about a natural phenomenon # Make observations of the phenomenon # Formulate a hypothesis that tentatively answers the question # Predict logical, observable consequences of the hypothesis that have not yet been investigated # Test the hypothesis' predictions by an experiment, observational study, field study ...

Manufacturing
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed int ...

Time And Motion Study
A time and motion study (or time-motion study) is a business efficiency technique combining the Time Study work of Frederick Winslow Taylor with the Motion Study work of Frank and Lillian Gilbreth (the same couple as is best known through the biographical 1950 film and book ''Cheaper by the Dozen''). It is a major part of scientific management (Taylorism). After its first introduction, time study developed in the direction of establishing standard times, while motion study evolved into a technique for improving work methods. The two techniques became integrated and refined into a widely accepted method applicable to the improvement and upgrading of work systems. This integrated approach to work system improvement is known as methods engineering and it is applied today to industrial as well as service organizations, including banks, schools and hospitals. Time studies Time study is a direct and continuous observation of a task, using a timekeeping device (e.g., decimal minute sto ...

Predetermined Motion Time System
A predetermined motion time system (PMTS) is frequently used to perform Labor Minute Costing in order to set piece-rates, wage-rates and/or incentives in labor (labour) oriented industries by quantifying the amount of time required to perform specific tasks under defined conditions. Today the PMTS is mainly used in work measurement for shorter cycles in labour oriented industries such as apparel and footwear. This topic comes under wider industrial and production engineering. One of such a system is known as "Work Factor" and more popular Methods-time measurement, (MTM) released in 1948 exist today in several variations and used in some commercial applications. New legislation in developed markets following sustainability issues, Living Wage movement and the 2013 disaster in Rana Plaza, Bangladesh have brought labor costing and standards back to the focus of activists and global fashion retailers.

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organizational Psychology
Industrial and organizational psychology (I-O psychology), an applied discipline within psychology, is the science of human behavior in the workplace. Depending on the country or region of the world, I-O psychology is also known as occupational psychology in the United Kingdom, organisational psychology in Australia and New Zealand, and work and organizational (WO) psychology throughout Europe and Brazil. Industrial, work, and organizational (IWO) psychology is the broader, more global term for the science and profession.Spector P. E. (2021). Industrial and Organizational Psychology: Research and Practice 8th ed. Hoboken, NJ: John Wiley. I-O psychologists are trained in the scientist–practitioner model. As an applied field, the discipline involves both research and practice and I-O psychologists apply psychological theories and principles to organizations and the individuals within them. They contribute to an organization's success by improving the job performance, wellbeing, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Organizational Behaviour
Organizational behavior (OB) or organisational behaviour is the: "study of human behavior in organizational settings, the interface between human behavior and the organization, and the organization itself".Moorhead, G., & Griffin, R. W. (1995). ''Organizational behavior: Managing people and organizations'' (5th edition). Boston. Houghton Mifflin, (p.4) OB research can be categorized in at least three ways: * individuals in organizations (micro-level) * work groups (meso-level) * how organizations behave (macro-level) Chester Barnard recognized that individuals behave differently when acting in their organizational role than when acting separately from the organization. Organizational behavior researchers study the behavior of individuals primarily in their organizational roles. One of the main goals of organizational behavior research is "to revitalize organizational theory and develop a better conceptualization of organizational life".

Job Analysis
Job analysis (also known as work analysis) is a family of procedures to identify the content of a job in terms of the activities it involves in addition to the attributes or requirements necessary to perform those activities. Job ''analysis'' provides information to organizations that helps them determine which employees are best fit for specific jobs. The process of job analysis involves the analyst gathering information about the duties of the incumbent, the nature and conditions of the work, and some basic qualifications. After this, the job analyst has completed a form called a ''job psychograph'', which displays the mental requirements of the job. The measure of a sound job analysis is a valid task list. This list contains the functional or duty areas of a position, the related tasks, and the basic training recommendations. Subject matter experts (incumbents) and supervisors for the position being analyzed need to validate this final list in order to validate the job analys ...

Profiling (computer Programming)
In software engineering, profiling ("program profiling", "software profiling") is a form of dynamic program analysis that measures, for example, the space (memory) or time complexity of a program, the usage of particular instructions, or the frequency and duration of function calls. Most commonly, profiling information serves to aid program optimization, and more specifically, performance engineering. Profiling is achieved by instrumenting either the program source code or its binary executable form using a tool called a ''profiler'' (or ''code profiler''). Profilers may use a number of different techniques, such as event-based, statistical, instrumented, and simulation methods. Gathering program events Profilers use a wide variety of techniques to collect data, including hardware interrupts, code instrumentation, instruction set simulation, operating system hooks, and performance counters. Use of profilers The output of a profiler may be: * A statistical ''s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staffing Models
Staffing models are related sets of reports, charts and graphs that are used to precisely measure work activity, determine how many labor hours are needed, analyze how employee time is spent and calculate costs. Staffing models are used in the healthcare industry and use predictive analytics methods for forecasting. Overview Staffing models provide: * A structure for staff scheduling * Staff interactions * Both a broad and in-depth picture of work activity, and its time and cost * Information about current resource and process performance * Information and tools to manage and improve staffing resource performance.
