User involvement is an important component in the
development of effective software engineering system. This
paper focuses on a study to draw the facts and to establish
the involvement of users in influencing the software
requirement practitioners and the system as a whole. It
also analyses the effects of different characteristics of the
users in the requirement process. Twenty-two software
practitioners working in different software multinational
companies across the world were involved in the survey.
In addition to this eight software practitioners working in
three companies were interviewed through internet
chatting. The analysis of the results of interviews and a
survey showed that requirement differs when the users are
from different educational backgrounds and geographical
locations. It also showed that documenting user’s
requirement improves the system considerably, but as the
number of user requirements increase substantially, the
customer-user differences also increases proportionately
