    In the present era of liberalization, privatization and globalization, industrial growth is probably the most critical factor while analyzing a country’s economy. Sustenance of industry primarily depends on its productivity levels in the highly competitive environment.

    Productivity enhancement can be achieved by using the principles of industrial engineering such as Work Study and Ergonomics.

    These principles have been addressed in this book in order to develop better understanding of the subject in the minds of readers pertaining to topics such as productivity, work and method study with measurements and ergonomics.
