Robotic process automation, often referred to as RPA, is an important component of business process automation and business process improvement. It helps organizations automate repetitive, rules-based work at the user interface level, allowing people to focus more of their time on work that requires knowledge, judgment, critical thinking, and experience.
This overview lays the groundwork for understanding RPA, sometimes also discussed in the broader context of intelligent process automation. The goal is to create a practical framework for thinking about where RPA fits, what it does well, how it differs from broader business process automation, and how it supports better business processes.
For business analysts, business systems analysts, technical teams, and subject matter experts, the larger purpose behind RPA starts with a familiar goal: better requirements. That means requirements that are complete, unambiguous, validated, and delivered faster.
Better requirements are valuable because they lead to better business systems. Better systems provide effective functionality, create customer value, reduce maintenance intensity, and deliver capability faster to the organization.
But business systems are still a stepping stone. The real value is created through business process. Business systems support business processes, and great business processes enable an organization to be highly effective, highly efficient, and agile enough to adapt over time. RPA fits into that value chain as one of the tools that helps improve how work gets done.
A useful way to think about RPA is to start with the two basic dimensions of an organization: the vertical dimension and the horizontal dimension.
The vertical dimension is the reporting and managerial structure of the organization. It includes the CEO, senior leaders, managers, associates, business units, departments, and work teams. Most organizations are organized vertically from a reporting and management standpoint.
The horizontal dimension is the business process dimension. It is the flow of work across activities. An order is entered, routed, fulfilled, packed, shipped, invoiced, or otherwise moved through a sequence of work activities.
That is all a business process is: a sequence of work activities. RPA becomes relevant when we look inside those work activities and ask which parts of the work can be automated.
One of the most useful ways to analyze RPA opportunities is what James Proctor describes as “splitting the atom of the work activity.”
Any work activity in a business process can be deconstructed into the procedure used to perform that activity. Within that procedure, some part of the work may be mechanical and rules-based. Another part may require knowledge, judgment, experience, and decision-making.
RPA is strongest when the work can be distilled down to a rules-based procedure. Those rules-based portions of a work activity are strong candidates for robotic process automation.
The knowledge and judgment-based portions of the work are not as easily automated through traditional RPA. That distinction is important. RPA is not about automating everything. It is about identifying the portions of work activities that are repetitive, rules-based, and suitable for automation.
Business process automation, or BPA, refers to the broader end-to-end automation and orchestration of a business process. It includes the tools, techniques, software, integrations, workflow engines, and technologies used to automate portions of a complete business process.
Business process automation can include enterprise software, ERP workflows, vendor workflow solutions, custom software development, APIs, web services, and system integrations. These approaches often require technical expertise because they interact with the software, database, code base, or underlying technical architecture.
RPA is a subset of business process automation. It typically works at the individual work activity level rather than across the full end-to-end process. RPA provides automation through bots that mimic human performance at the user interface level.
The important distinction is that RPA is technically non-invasive. It is largely independent of the underlying technical architecture of the applications it interacts with. Instead of changing the system, database, or code, RPA automates the work at the user interface level.
In practical terms, an RPA bot can perform actions similar to what a person does at the keyboard. It can enter data, copy information, paste information, trigger functionality, move between applications, and execute routine transactions when the procedure is rules-based.
That makes RPA a hybrid approach. It draws on the expertise of subject matter experts who understand the work, with technical talent involved as needed to establish the environment, guardrails, governance, and support structure.
At its core, robotic process automation uses software bots to mimic selected human tasks within a business or IT process. These bots can activate keystrokes, interact with one or more software applications, manipulate data, pass data between systems, trigger responses, and execute transactions.
The bot overlays one or more applications and performs the steps a human would otherwise perform manually. For example, if someone is entering an invoice, creating a customer account, copying data from an email into another system, or moving information between two applications, RPA may be able to automate part of that work if the steps are rules-based.
RPA is especially useful when the work is repetitive, predictable, high-volume, and rule-driven. It is not intended to replace every part of the process. It is intended to automate the portions of the work where bots can perform consistently and efficiently.
One of the most common use cases for RPA is solving what is often called the “swivel chair interface” problem.
A swivel chair interface exists when a person has to interact with multiple systems at the desktop level because those systems are not integrated. An employee may copy data from an email, paste it into another system, move to an accounts receivable application, update a customer account management system, and then return to another screen to complete the task.
People can do this work, but it is often tedious, monotonous, and error-prone. People are much better at complex thinking, problem solving, customer engagement, and judgment-based work than they are at repetitive data entry and manual system-to-system movement.
RPA can automate parts of that swivel chair work as an interim or tactical solution. It does not replace the value of deeper system integration, but it can create meaningful value while IT teams continue to prioritize larger integration and modernization efforts.
