With the increasing demand of customisation and high-quality products, it is necessary for
the industries to digitize the processes. Introduction of computers and Internet of things
(IoT) devices, the processes are getting evolved and real time monitoring is got easier.
With better monitoring of the processes, accurate results are being produced and accurate
losses are being identified which in turn helps increasing the productivity. This introduction
of computers and interaction as machines and computers is the latest industrial revolution
known as Industry 4.0, where the organisation has the total control over the entire value chain
of the life cycle of products. But it still remains a mere idea but an achievable one where IoT,
big data, smart manufacturing and cloud-based manufacturing plays an important role. The
difference between 3rd industrial revolution and 4th industrial revolution is that, Industry
4.0 also integrates human in the manufacturing process. The paper discusses about the
different ways to implement the concept and the tools to be used to do the same.
Low cost manufacturing of quality products remains an essential part of present economy
and technological advances made it possible. Advances and amalgamation of information
technology bring the production systems at newer level. Industry 4.0, factory for future,
smart factory, digital manufacturing, and industrial automation are the new buzz words of
industry stalwarts and academicians. These new technological revolutions bound to change
not only the complete manufacturing scenarios but many other sectors of the society. In this
paper an attempt has been made to capture the essence of Industry 4.0 by redefining it in
simple words, further its complex, disruptive nature and inevitability along with technologies
backing it has been discussed. Its enabling role in manufacturing philosophies like Lean
Manufacturing, and Flexible Manufacturing are also
