Task analysis benefits

If a safety professional really wants to know what hazards may create problems tomorrow, task analysis is a highly effective way to identify them. Of course, the process would culminate in proposals for the appropriate preventive actions. The ancillary benefits are considerable, since many people can be trained through the task analysis process to identify hazards and how to seek their elimination or control. 

Task analysis performed appropriately wiU identify areas of waste, in terms of time, resources, production, and dollars. It will also identify areas where efficiency can be improved, thereby increasing productivity. These benefits are achieved while at the same time improving safety and general morale. 

Benefit Example 1. At a large gold mine in the western United States, task analysis provided the impetus for management to change their procedures and management style. 

To achieve the benefits we saw in the previous section, we need to conduct an extremely detailed task analysis. To do this, we need to draw on all levels of knowledge and expertise. Task analysis begins with the workers and front-line supervisors. 

To fully realize the benefits of task analysis and the subsequent improvements (e.g., SOPs, training, and other modifications that have occurred), we must develop a formal procedure to observe the task. This will enstue that old habits and steps don t come back, and it may identify other areas to improve. 

A complement to traditional task analysis in that it retains the benefits of these methods but also adds the capability for designing for the unanticipated by describing the constraints on behaviour rather than behaviour per se. 

Another potential benefit of UHPLC is its capability of solving the most challenging separation tasks in pharmaceutical analysis. Figure 9.4 shows a UPLC method developed to analyze pharmaceutical formulations used to treat the common cold. Cold products often contain multiple active ingredients to treat different symptoms and can contain decongestants, antihistamines, pain relievers, cough suppressants, expectorants, and numerous excipients of various polarities. The analysis of a total of 20 components was achieved within 10 min. 

To ensure that the rights and welfare of human research participants are protected, the IRB takes on the task of performing a risk vs. benefit analysis. Before a clinical trial can be initiated, foreseeable risks and inconveniences should be weighed against the anticipated benefit for the trial participant and for society (Section 22.2). Risks associated with participation in research should be justified by the anticipated benefits only then, can the trial be initiated. Because this requirement is clearly stated in the federal regulations, it is, therefore, one of the major responsibilities of fhe IRB to assess fhe risks and benefits associated with proposed research. Definitions of fhe terms fhaf fhe IRB uses to assess risk include the following ... 

The principal operations involved in a chemical analysis are set out in Fig. 1.1. In considering the benefits of automating an analysis, each step in Fig. 1.1 must be taken into account. SampHng requirements will often not be amenable to automation and the task of reporting the result to the end-user may not be clearly defined. Analysts are often not involved in either the choice of sample nor in the reporting of the result—I beheve that it is important that they should be. For example, a sample which is not representative of the material it comes from will be of no real value, just as the reporting of a result without full justification of its precision is pointless. 

Cost benefit analysis is not always easy or straightforward. One of the tasks is to accurately determine the risk if the recommendation is rejected. Cost benefit analysis is also used for comparing different actions (options) for addressing the recommendation. These determinations require examining a... 

Ocular endotamponades based on FCL are and will be interoperative tools. They have to be removed after use. The risk-benefit analysis must be the base for defining the maximum treatment period. The mean task of these devices is space filling/maintaince. 

If the cost-benefit analysis or user preference points toward the use of throttling valves, the next task is to select the right valve type for the application. As shown in Table 2.61, the various valve designs have different pressure... 

The intent in this chapter is not to present in great detail the mathematics behind the statistical methods discussed. An excellent reference manual assembled by the Automotive Industry Action Group (AIAG), Fundamental Statistical Process Control, details process control systems, variation, action on special or common causes, process control and capability, process improvement, control charting, and benefits derived from using each of these tools.
