Measurements perception surveys

Even for the large organization with significant annual hours worked, in addition to historical data, hazard-specific and qualitative performance measures (safety audits, perception surveys, the incident... 

For example, I then wrote that since 1980, no articles had been published in the magazine Professional Safety that had performance measures or performance measurement in their titles or abstracts. A further search was made using effective and effectiveness as the key phrases. Two articles were found The June 1981 issue of the magazine contained How Do You Know Your Hazard Control Program Is Effective, written by Fred A. Manuele the February 1989 issue included Using Perception Surveys to Assess Safety System Effectiveness by Charles W. Bailey and Dan Petersen. 

Literature on the program instmcts senior management that the overall culture of the organization should be measured. This is Petersen s view of perception surveys. 

A perception survey provides management with a performance measure of itself. Major proposals deriving from such a survey — leading indicators if you like—should affect the pattern of expected behavior of senior executives, and thereby the culture. 

More recently, safety people have applied leading, upstream, predictive, activity, preventive or process indicators or metrics to measure safety performance. This family of measures often includes safety audits, behavior-based safety measures, safety perception surveys, safety training, corrective actions completed, reductions in risk and risk factors, identifying safety and ergonomic opportunities, and other measures. Many use leading indicators to do the following ...

Likert invented a way to measure climate with a forced choice questionnaire that he administered to employees to find out their perception of how good the company is in the ten areas. He later took the perception survey results and ran correlation studies with things like profitability, return on investment, growth, and other bottom-line figures, invariably coming up with extremely high positive correlation. Apparently, climate determines results [3,4]. We will discuss employee safety perception and how it will affect the operation in more detail in Chapter 17. 

One of the more recent and one of the best measurement tools is the perception survey. 

Perception surveys have also been used to provide measurements of the quality of safety management systems in place. Through an interview system or the completion of surveys, they provide management with a picture of what employees at various levels of responsibility think about the management of safety in the organization. Perception surveys are outcome surveys in that the perceptions people have of how safety is managed derive from their observations of what got done or didn t get done with respect to the safety system elements covered in the interview or questionnaire process. 

Perception surveys are commonly used to measure attitudes. They tell us what people s impressions are, and provide information needed to address fundamental program problems. They are a true indicator of how well the site s programs are reaching employees. 

The impact of an intervention can be measured by comparing perception surveys given before and after implementation. At one plant, our baseline Safety Culture Survey indicated that secretaries had below-average levels of perceived empowerment, as assessed by the measures of self-efficacy, personal control, and learned optimism described earlier in Chapter 15. A special recognition intervention was devised and later the survey was administered again to measure changes in the five actively caring person states as well as safety perceptions and attitudes. 

For example, a correlation of 0.30 between the results of a safety perception survey and other measures of safety, such as employees frequency of coaching sessions completed or percentages of at-risk behavior per observation period, sounds good until you realize that only 9 percent of the variance in one measurement device could be accounted for by the other (0.30 = 0.09 or 9 percent). In this case, 91 percent of the variance in people s safety perception scores could not be explained by the other estimate of a person s safety. 

Throughout this Handbook, I have presented various questionnaires that assess particular person states to gauge reactions to interventions. Such evaluation tools are not as objective and directly applicable to process improvement as feedback charts from behavioral observations. Results of surveys to measure perceptions, attitudes, or person states... 

Despite differences in methodology, the NHSDA data and the MTF survey have shown similar long-term trends in the prevalence of substance abuse among youths. In addition to measuring prevalence, these surveys discuss teen perceptions of the harmfulness of drugs, their approval/disapproval of the use of drugs, and the availability of drugs. 

For each customer segment, identify performance (objective and measurable) and perception (subjective) expectations. You can gather this information using customer surveys, focus groups, or interviews. The specific approach will depend, in part, on the level of innovation in your solution—it would be difficult for people to complete a survey, for instance, on a completely new offering they have never seen, although a survey would be in order if you re simply adding new features to a well-known product. 

The first thing to note is the relatively immature tradition of public opinion surveys in Italy, compared to the USA in particular. The work presented here is therefore less an attempt to precisely measure the full economic value of groundwater protection and more a case of exploring peoples priorities, understanding and perceptions of water quality. 

One of the classic problems encountered in this type of research is that the tools used don t measure the variables in the question asked. Instead, tools are often used that measure convenient variables even though these variables don t address the question. For instance, if you want to know if a particular teaching innovation results in student learning, using a survey that asks students if they like the innovation does not necessarily answer the question of whether the innovation increased student learning. It is true that a positive student perception...
