Limitations of RPA in Manufacturing
- Expensive - The use of RPA means extra investment in technology and, with it, required training costs. Depending on the processes, the relevant personnel has to be taught to deploy RPA to perform effectively in their absence. Hence for RPA to be successful, the manufacturer needs to consider substantial technology and training investment before reaping the benefits, which may not be suitable for every company.
- Limited suitability - RPA is designed to suit rule-based tasks and processes that have no variation. Suitable for repetitive tasks, RPA may not suit tasks that need to be changed or are complex and need human intervention.
- Inflexible - Most of the RPA solutions in manufacturing are custom-made depending on business requirements. Hence, any changes to the rule-based processes may not be accommodated, leading to unnecessary maintenance costs.
- Increased risk - RPA bots cannot replace human ingenuity. They cannot spot errors or problems as humans can. If there is anything wrong with the data, they might ignore or process it incorrectly, increasing risk and delays in the process.

Use Cases for RPA in Manufacturing
RPA may be applied to automate many processes in the manufacturing industry. A few of them are detailed below:
1. Purchase order creation
Purchase orders (PO) are crucial to manufacturing organizations, and a considerable amount of effort and time is spent on them. The complexity increases when there are multiple categories of products present, making it a formidable task. RPA solutions can simplify the entire PO by following a predefined rule-based workflow. This automated process includes extracting relevant data, getting approvals from respective heads via emails, and enabling the smooth processing of PO creation.
2. Inventory management
Inventory management is an important aspect of supply chain management. Adequate inventory levels are necessary to ensure that production can start to meet consumer demands. Along with inventory management, inventory reporting aids in optimizing supply chain processes for enhancing overall production and revenue.
Functions such as monitoring stock levels, initiating of alerts/ reminders on replenishing stocks, reordering of items, tracking deliveries, sending email responses, and generating reports are some of the things that RPA can take care of.
3. Invoice processing
Invoice processing is a highly rule-based process that makes it an excellent choice for using RPA. This crucial process also helps manufacturers maintain smooth and strong relationships with their vendors.
Extraction of invoice data, matching invoices with purchase orders, delivery receipts, etc., identification of duplicate invoices, and updating records can all be possibly automated with RPA.
4. Customer Service
Manufacturing industries also need to focus on customer service to keep them satisfied and happy. RPA solutions that have a chatbot feature can use that to act as a first-level response to customer queries, even during non-working hours.
They can also be automated to respond to emails to reduce waiting periods and to make up for the absence of staff. This enables manufacturers to ensure customers are taken care of at all times.
5. Bill of Materials (BOM)
The bill of materials is a crucial document for all manufacturers. It is a detailed list of the raw materials, components, and more items that are needed for manufacturing a particular product.
RPA can assist in making standard templates available for creating new BOMs, Identifying and alerting for missing documents, and picking alternative components from databases for use to ensure that production is carried out smoothly.
Apart from all the above, RPA can also be used for the automation of certain HR processes, transportation, sales & marketing, and more to add value and ease obstacles in manufacturing concerns.
