More enterprises have adopted RPA functions to automate rote, repetitive tasks, but sometimes they need more capabilities. Enter machine learning functions and the result is “intelligent automation” which, unlike RPA, can learn and adapt.
The choice between the two should depend on the use case, but in today’s AI-crazed world, there’s a misconception that intelligent automation must be better when, in fact, robotic process automation (RPA) may be a more elegant solution.
“We view AI/ML as knowing what to do, RPA is knowing how to do it,” said Muthu Alagappan, chief medical officer at intelligent automation platform provider Notable Health. “For example, OCR can be used to extract information from insurance cards, photo IDs and clinical documents. From there, RPA [enters] the extracted data into existing systems of record.”
How RPA and machine learning work together
RPA simply executes its programming, so if requirements change, it needs to be reprogrammed. Machine learning is more dynamic.
“Machine learning relies on large data sets to inform computer systems how to make decisions,” said Tommy McEvoy, senior lead technologist in the AI practice at management and IT consulting firm Booz Allen Hamilton. “An exciting advancement in the automation space is the integration of these capabilities, where RPA becomes the engine that accelerates ML, NLP and AI capabilities with the ability to produce an output at scale.”
By having RPA rapidly clean and feed data into a machine learning algorithm, an organization can achieve a fully automated solution. For example, Booz Allen developed fully automated service solutions that can capture a customer’s refund requests over the phone, transcribe that information, classify the customer’s intent and then translate all of that into an appropriate trigger for the automation.
“A true automation platform includes RPA and machine learning, as well as decision management frameworks and event architectures to trigger actions,” said Bill Lobig, VP of product management at IBM. “RPA has driven a significant rise in document extraction technologies, systems integration and process mining. I think all of these things together are what you need for intelligent automation, but certainly RPA and machine learning are a big part of it.”
Computer vision and RPA
Genpact, a global IT technology services company, uses computer vision to make RPA more effective and more applicable to a wider range of use cases. The company also pairs machine learning with computer vision to discover and mine existing business processes, as well as their deviations and variations. The company also uses machine learning to look at RPA engine log files to determine the root cause of issues that need to be resolved in RPA.
“We use the computer vision capability a lot because there’s a lot of unstructured data sitting in PDFs and other things,” said Sanjay Srivastava, chief digital officer at Genpact. “We use ML for three things: designing the [process automation] configuration rules, execution and eliminating systemic upstream issues that drive downstream problems.”
Srivastava also underscored the need to build a data foundation, which some organizations overlook.
“I find people jumping into RPA without having thought through that. Data science professionals know they can’t get a thought out of the garage unless they have a database structure set up, so …….
