Instead of robotics and IoT, think first about ensuring your foundation is solid. You wouldn’t renovate your home on a crumbling foundation, would you? So then, why do it in your business? Your first step toward improvement should be through foundational changes such as an ERP system. An ERP system will act as your central point of intelligence and support your process of ongoing improvement.
I’m reminded of the book The Goal - A Process of Ongoing Improvement by Dr. Eliyahu Goldratt and Jeff Cox. There's a conversation that takes place between the leading character, a production manager, and an old instructor of his.
The instructor asks how is business in the factory, to which he is told how things are going great following a recent investment in factory robots. Now all work centers on the shop floor are running at full capacity and efficiencies are way up.
The professor responds by saying, ok, but has the increase in production with the robots resulted in an increase in profit? The answer is no, because they haven’t first looked at the organization to identify flow constraints and and submitt all other processes to the constraint’s capacity.
Essentially, what they’ve done is add extra production capacity everywhere, therefore likely overloading the constraint, increasing WIP inventories, and decreasing throughput. The goal of any organization should be to make a profit which is achieved through an increase in throughput.
So the message to a manufacturer is, before you concern yourself too far with the promises of Industry 4.0, give careful calculated consideration to your current modus operandi and ensure you are clear where your constraints exist, and manage them appropriately. Once you’ve completed that exercise, then you can start looking at what enhancements Industry 4.0 technology can add to your operations.
