Dear Sanjukta,
The problem with the training profession is that there are no entry point barriers. Therefore, self-certification is sufficient to become a trainer and anyone can enter in the field. However, this self-certification does not make one mature.
After working for 10 long years as HR Generalist also, why a thought of measurement of training effectiveness did not occur to you is beyond my comprehension. Do you mean to say that you did not measure human productivity in your decade long career as HR generalist? How is it possible?
While starting any training programme, whether for team building or otherwise, one should start with measurement of its effectiveness after definite time span like three months, six months etc. Neither you did this nor your client told you to do so. This is the bane of HR profession is. Little do HR professionals understand that their bosses are interested in measurement of ROI of everything that includes training as well. CEOs consider HR's inability to measure ROI as their inability to add value and in turn they are valued less compared with their peers.
Anyway, take this training assignment is wake up call and at least now on be measurement oriented! It appears that you are yet to understand the fundamentals of the training function. I have been giving replies on the subject of employee training for the years together. You may go through the following link to refer my one such reply. The link is as below:
