Productivity improvement is vital to sustaining in the market. This work outlines the significance of productivity improvement encompassing quick changeovers, fixture design modifications and improved material handling thereby meeting the demand requirements. There is the total of 10 component varieties such as D88 U1, D88 L1, D110 U2, D110 L2, D132 U3, D132 L3, D150 U4, D150 L4, D168 U5 and D168 L5. D88 contributes to 82\% of part production and hence termed as high-volume components whereas D110, D132, D150 and D168 components are termed as low volume components. In the current state, there were totally 7 machines but in the future state, there would be only 4 machines. Out of 4 machines, 2 machines will be delivering the same output of 220 D88 parts per day as of Mar-2021 and the other 2 machines will be satisfying fluctuating order arrivals at low volume production line. Apart from effective utilization of resources, deploying the latest technologies is equally important in this competitive environment. Industries needs to incorporate the growing technologies to sustain in the market. Internet of Things (IoT) connects the physical world with the digital word and makes life simple by automating a wide variety of processes across diverse environments available. This work highlights the usage of the Industrial Internet of Things (IIoT) for replenishment systems in a small-scale industry environment and outlines the effect of productivity improvement. This idea will be beneficial if done at a low cost, unlike the inventory management software which is priced quite higher and seems unaffordable to small-scale industries.
