RESEARCH DESIGN:

RESEARCH DESIGN In assessing OD Interventions, practitioners have turned to quasi-experimental Research design with the following features: Longitudinal measurement: This involves measuring results repeatedly over relatively long time periods. Ideally, the data collection should start before the change program is implemented and continue for a period considered reasonable for producing expected results. Comparison unit: It is always desirable to compare results in the intervention situation with those in another situation where no such change has taken place. Although it is never possible to get a matching group identical to tile intervention group, most organizations include a number of similar work units that can be used for comparison purposes. Statistical analysis Whenever possible, statistical methods should be used to rule out the possibility that the results are caused by random error or chance. Various statistical techniques are applicable to quasi experimental designs, and OD practitioners should apply these methods or seek help from those who can apply them.

Assessing OD Changes:

Assessing OD Change s The use of multiple measures also is important in assessing perceptual changes resulting from intervention. Considerable research has identified three types of change Alpha, Beta, and Gamma change.

OD CHANGES:

OD CHANGES Alpha Change: It concerns a difference that occurs along some relatively stable dimension of reality. . For example, comparative measures of perceived employee discretion might show an increase after a job enrichment program. If this increase represents alpha change, it can be assumed that the job enrichment program actually increased employee perceptions of discretion. Beta Change: It refers to recalibration of units of measure in a stable dimension. Gamma change: It involves fundamental redefinition of dimension.
