RPA and process automation

Robotic process automation, or RPA, uses software robots that click, type and copy between applications the way a person would. It grew up in finance, insurance and back-office operations, where many systems have no API and the only way in is through the screen.

The large RPA vendors have added AI on top of that base. Robots can now read documents, classify emails and hand parts of a process to an AI agent while the rest runs as fixed steps. UiPath and Automation Anywhere cover this full range, and both include tools for finding which processes are worth automating. SS&C Blue Prism is common in banks and other regulated companies. Appian, Pega and Nintex come at the same problem from process management, with workflow, forms and case handling around the automation.

RPA suits stable, repetitive processes. Screen-based robots break when an application changes its layout, so ask how each tool detects that, how it alerts you and how quickly a robot can be repaired. Where an application has an API, an integration is usually sturdier than a robot reading the screen.

These platforms need some structure around them. Robots log in with credentials, so plan where those are stored and who can change them. Decide who owns each robot, how changes are tested and what the team does by hand when a robot is down. Several vendors offer a free community edition, which is a good way to try a real process before you talk to sales.

Measure the process before you automate it. Count how often it runs, how long it takes by hand and how many exceptions it has. A process with many exceptions often needs to be simplified first, or the project turns into a long list of special cases that nobody wants to maintain.

RPA projects also need a plan for change. Applications get updated, screens move and business rules shift during the year. Keep a short test for each robot that runs after any update to the systems it uses, and agree with IT on how you will hear about upcoming changes. A robot that fails quietly for a week can cost more than the time it saved.

Licensing for RPA is usually counted per robot, per user or per process, and attended robots that help a person at their desk are priced differently from unattended robots that run on a server. Ask which model fits your plans before you build.

Questions about rpa and process automation

When is RPA the right choice?

When a process is stable and repetitive and the systems involved have no usable API. If the apps offer an API or a connector, an integration platform is usually easier to maintain over time.

Can I try these tools for free?

UiPath, Automation Anywhere and Appian offer free community editions for learning and small trials. Check the license terms, because community editions usually can’t be used for production work in larger companies.

What breaks RPA robots most often?

Changes to the screens they work through: a moved button, a new login step, a pop-up that wasn’t there before. Ask each vendor how robots detect these changes and how alerts reach the right person.

How should robot credentials be handled?

Store them in a credential vault, give each robot its own account where possible and limit what that account can do. Review the access regularly, the same way you would for a member of staff.
