The world of work has always been subject to continuous and ever evolving
             transformations and changes. Change is essential in an organization.
             Technology has changed the way we work and live. In the pre-industrial
             era, workers lived in isolation; they crafted goods required at their homes
             and farmsâ€"people worked hard at being self-sufficient. The industrial
             revolution in the past century changed our way of life. People moved to
             cities and townsâ€"pre-determined by the locations of factories and
             industries. The new worker was often taught a single skill that was used
             repetitively in mass productionâ€"in an assembly-line setup. Whereas in the
             past, an individual sold goods and produce that he or she personally
             created or grew, the modern day worker sold his time. (Curry, 2003)
             The Human Resource Department's functions have changed and the department
             is taking on more duties and responsibilities than in the past. The HR
             department is becoming a strategic partner for the organization as it holds
             the most important asset a company possesses under its controlâ€"the human
             asset. The human asset cost is currently a major portion of the expenses
             that organizations face. Technology, the Internet and globalization of the
             market have drastically changed the way most organizations operate.
             Knowing and understanding the variables affecting the present day
             organizations and the models that the modern HR departments prefer will
             help organizations to use their human resource asset more effectively.
             More than physical and other resources, changing the mindset and the human
             factor will ultimately come to represent the new competitive edge for a
             Communicating the goals and mission of the company effectively to all
             employees...
