Some time people have a tendency to ignore procedure & find short cuts to get the out-puts of given problem.
Regarding adjusting system the analyst need to find out how they are feeling forms & how useful they are to the user, what type of changes required by the user & how it is easy to read.
The another type of fact finding method which is used by the system analyst is on-site observation. The purpose of on-site observation is to get a close study of the possible requirement for the system.
For this purpose the analyst follows the set of rule’s which he/she used whenever he/she do the observation at the site.
On-site is the most difficult fact finding technique. It request intrusion in to the user’s area & can cause adverse reaction by the user staff if it is no handled properly.

- what behavior can be observe that can’t be described in any other way?
- What data can be obtained more easily & also reliable by the observation ?
- What assurance can be given that the observation process is not seriously affecting the system, being observed ?

So the reliability& validity of the information collected depend on the design of the interview or questionnaires.
In an interview, since the analyst or interviewer & the person interviewed meet face to face, there is an opportunities for greater flexibility in collected information.
