RPA in Manufacturing: Game-changing Benefits and Use Cases With the Fastest ROI

Industrial owners are losing a fortune and seeing their productivity plummet due to mundane repetitive manual tasks, inevitable human errors, and employees drowning in spreadsheets. RPA in the manufacturing industry helps to root these issues out.

With ever-present budgetary constraints and tight deadlines, RPA stands out as a relatively cost-effective, fast, and low-risk way to strengthen operations. It’s less complex than other enterprise automation technologies, like smart physical robots within production sites or digital twins that mimic factory floors. 

Organizations report a typical payback of 250% within two or three quarters after RPA adoption. Pretty impressive, isn’t it? Some high-performers have even achieved a 380% return on automation investments.

This is just a small part of why spending on robotic process automation software is forecast to grow at a CAGR of 36.6% from 2022 to 2032. 

Having mastered RPA inside and out, our experts are eager to share hard-won insights distilled from over 20 years on the front lines. Let’s delve into the mechanics of RPA, its transformative benefits, and real-world applications, illustrating how this technology is propelling the industry toward excellence.

What is Robotic Process Automation in manufacturing, and how does it work? 

Robotic process automation (RPA) is a technology manufacturing businesses use to automate high-volume, repeatable tasks.

Using scripts that emulate human actions, software robots are there for you to perform repetitive tasks. They log into enterprise applications, move files, open and send emails, fill in forms, and tackle all that white-collar worker’s daily routine.

The sweet spot for RPA lies in automating rule-based, straightforward, and mostly high-volume tasks. Completing them manually is time-consuming, error-prone, and far from creative yet vital to keeping the factory running. Meanwhile, bots do them all way faster and without lapses.

See it in action:

• Before automation: a manufacturing company receives hundreds of invoices from various suppliers each month. Employees manually input invoice data into the ERP system, verify details, and process payments. The process itself is a bottleneck, often leading to delays and inaccuracies.

• After automation: an RPA bot handles the end-to-end process in seconds, signaling only in case of exceptions where manual validation is required.

There is also a more advanced form of RPA called cognitive automation. It aims to overcome the limitations of traditional RPA by applying more intelligence to tasks, hence adding some recognition and analysis capabilities.

Four benefits of RPA in manufacturing you can’t ignore

RPA turns out to be a game-changer for the manufacturing industry in many ways. By streamlining complex operations, enhancing precision, and slashing costs, it empowers manufacturers to pivot from routine tasks to strategic innovation.

Lower operational costs

Wiping out costly errors and freeing up staff from mundane duties makes RPA an instrumental add-on to your cost-reduction strategy. 

Typical savings on current operational costs range from 25% to 80%, which can translate into tens of millions of dollars annually for some organizations.

Moreover, the speed and accuracy of automation help reduce administrative, prevention, appraisal, and internal/external failure costs — the list can go on and on. 

Enhanced regulatory compliance

Apart from RPA-driven cost reduction, organizations also reap benefits like improved compliance, recognizing the impact of the technology on enhancing efficiency. 

With RPA’s capability to cross-reference raw materials and testing results against regulatory requirements, update compliance documents in real time, and, overall, facilitate adherence to regulations, meeting even stringent standards, such as FDA’s Current Good Manufacturing Practice (CGMP) or equivalent EU legal guidelines, becomes a breeze.

Our client, a leading manufacturer with production plants across the APAC region, stated: “Taking care of compliance and internal checks from the outset of our RPA journey was a brilliant move. Deploying multiple bots has boosted overall process quality and ensured reliable execution.”

All aspects of the manufacturing process can be automatically tracked for compliance with established standards, safety guidelines, legal requirements, and environmental regulations.

Increased productivity

RPA transforms how dozens of routine but critical tasks are handled. The tireless digital workforce completes these tasks in seconds with near-zero error rates. 

Automation can be especially helpful when organizations experience a labor shortage. With RPA in place, all operations run efficiently even during high-volume activity and peak workloads. 

Up to an 85% improvement in time efficiency and saving over 1000 hours or 199+ FTE days can be achieved simply by replacing humans in data entry tasks. Imagine the productivity gains after automating other tiresome back-office routines.

Any way you slice it, the outcome is freeing up thousands of labor hours yearly and increased productivity as workers focus on higher-value, meaningful work.

Improved quality and accuracy

High quality is always a matter of a strong reputation and profitability. Cost of poor quality (COPQ) can amount to 15-20% of sales revenue, with some reaching up to 40% of total operations.

Let’s recall traditional Bill of Material (BOM) management, which often suffers from manual errors. Incorrect quantities or assembly instructions, inconsistent updates, and difficulty tracking changes lead to defective products, wasted resources, and costly rework. Automation software accurately updates BOM data and transfers it into ERP systems, making sure nothing is overlooked, even when changes occur. Zero — that is the number of errors in BOM management you can expect after adopting RPA.

In production lines, RPA maintains stringent quality specifications, reducing defects in final products. Bots consistently perform quality inspections, minimizing the risk of human oversight. After implementing RPA in their quality assurance processes, most of our clients reported up to a 60% reduction in product defects.

Use cases where RPA in manufacturing pays off 

Manufacturers turn to RPA for value-creation opportunities in time-consuming and repetitive processes such as procurement, inventory management, and payment processing. Below, we list examples of RPA manufacturing use cases with the top tasks primed for automation.

Back-office tasks

Purchase orders (PO), status reports, avoiding duplicates, updating invoice records… The manufacturing back office thrives on documentation. Thanks to RPA, a range of operational activities can be completed fast and flawlessly.

Invoice processing

Instead of manually sifting through files and matching numbers, employees can focus on more strategically significant tasks, leaving the meticulous checks to robots.

RPA bots can automate invoice processing by extracting data, validating information, and routing invoices for approval. Here’s a breakdown of what exactly they are capable of:

• Downloading and extracting data from supplier invoices using Optical Character Recognition (OCR) technology
• Verifying data accuracy by comparing it with purchase orders and product catalogsRouting invoices for approval based on predefined rules (for example, amount thresholds)
• Generating automated payment schedules and sending them to the accounts payable department

Leading manufacturing companies using RPA-enabled invoice processing report that over 80-90% of all invoices are handled without requiring manual inspection. 

An invoice automation project, delivered by the *instinctools team for a multinational manufacturer resulted in $0.9 million in annual cost savings.

Order fulfillment

An automated process of order fulfillment is more accurate, as it fends off errors from the outset. What are the common order-related tasks manufacturing companies can automate?

• Data entry of customer orders received through various channels (email, website, etc.)
• Order verification and stock level checks
• Automatic generation of picking lists and documents from shipping processes
• Sending order status updates to customers

Data entry

Repetitive data entry tasks across existing systems are the most obvious target for automation. Such RPA examples include:

• Updating inventory databases with new stock entries (e.g., raw materials)
• Entering production data from machine logs into relevant software
• Transferring customer information from web forms to CRM systems

When a fast-growing beverage distributor faced challenges in managing data flows within their newly implemented enterprise application, they turned to us for a solution. To address the client’s data entry and management hurdles, we deployed RPA software, streamlining data quality checks and automating the input of new product versions into their new ERP system. This strategic move replaced a labor-intensive process with a single, highly efficient bot, amping up operational efficiency and setting the stage for scalable growth without increasing the headcount.
