? Scope of analysis. 。 ? Realism of the oute data。 ? Methodology of the study。 ? Motives of the researchers。 ? Can nontraining effects be isolated? ? What are the constraints in terms of using the data collection technique and isolation strategy. Credibility of Data is Influenced By: ? Reputation of the source of the data。 ? Expertise to conduct study。 ? The process can be very credible if the method used to isolate the impact of other factors is credible. Which Strategy? ? Control group feasibility。 ? In terms of this approach, the intervention claims credit for improvement that cannot be attributed to other factors。 ? This approach has some disadvantages. Data from subordinates is subjective and may be questionable because of the possibility for biased input。 ? They can also provide input in terms of what other factors might have contributed to the improvement。 ? Often top management place more confidence in outside experts than in their own staff. Obtaining Input From a Target Group ? An example is the subordinates of the supervisors trained in people handling skills。 ? Organization culture will determine whether the oute will be accepted。 ? If capacity does not exist in the anization。 ? The confidence level, expressed as a percent, is multiplied by the improvement value to reduce the amount of the improvement by the potential error。 ? Extreme data and unrealistic claims are omitted from the analysis。 ? Although an estimate, this value will usually have considerable credibility with management because participants are at the center of the change or improvement。 ? Based on the assumption that participants are capable of determining or estimating how much of a performance improvement/impact is related to the intervention。 ?
