Dear Nipuna,
There is a post on this site related to Training Needs Analysis today itself. You click the following link to read that:

Secondly, for TNA you do not require a psychometric questionnaire. Please concentrate on the following:
a) Customer Dissatisfaction
b) Operational failures
c) Report from Performance Appraisal of the employees
d) Organisational issues like conflict etc
e) Vision of your organisation like acquiring certification for ISO, six sigma etc.
f) Career Planning and Succession Planning.
Do to do everything above will require a couple of years.
Psychometric Tests are training tools. Please do not confuse the tools with the need to use that tool.
Thanks,
Dinesh Divekar
