Hi Ahmed. How about using intentions to remain in the organisation? This would gauge attitudinal and behavioural aspects of organisational commitment.

You may also want to look at actual improvements in organisational performance because positive or negative behavioural changes from change efforts are likely to also be reflected at an organisational level, however this is defined.

Hi Thomas,

Thanks for your comment. The organizations I am dealing with are public sector organizations. In my country, employees remain in their organizations until they retire, regardless of the changes happening in the organization.

Hi Renzo and Bangani,

Thanks for your comments

Are you aware of any measurement scales which can be adapted?

Outcomes are  related to processes.Behavior is changeable concept.For understanding outcomes (Negative-Positive) need to make a check list or questionnaire based on your selected areas.As it is not enough, to prepare interview schedule,observe and check the answer with comparing check list or questionnaire's answer.Observation and discussion are the best way.But it  is controlled by context, time and sample size.Group interview might be possible.
