• Every organization wants to lower its costs and keep up with change. Using technology effectively is an important part of doing both. Yet business needs can sometimes outpace an IT group’s ability to satisfy those needs.
• For example, automating a business process can make it faster, more reliable, and less expensive. But doing this typically requires integrating multiple applications, which can be time consuming and expensive.
• And once the integration is done, the process is often hard to modify. What’s needed is a way to automate a business process quickly while still letting that process adapt to change.
• One way to do this is through presentation integration. Once derisively known as “screen scraping”, this technology has matured into an effective approach to interacting with applications.
• Because it’s simpler than more traditional integration technologies, using presentation integration to automate a business process can be faster and less expensive. And because presentation integration can be used today on a wider scale than was possible with screen scraping, it can support enterprise processes.
• This makes it useful in a variety of situations, including cases where automating a process in the traditional way would be too expensive.
• Blue Prism provides process automation based on presentation integration.
• By providing tools for business analysts, the product can also help people who aren’t technology specialists create and modify automated processes.
• And by exposing application user interfaces through reusable services, it can help those applications fit into modern service-oriented environments. This paper describes Blue Prism, explaining how the technology works and how it attempts to reach these goals.

• Automating business processes requires connecting to the applications that support those processes.
• This can be done using either presentation integration or an alternative that’s often called business logic integration.
• As the left side of the figure shows, business logic integration uses adapters that connect directly to each application’s business logic.
• The automated process then interacts with these adapters to carry out the steps required.
• The right side of the figure shows the alternative, presentation integration. Here, adapters connect to the user interface of each application (how the application “presents” itself to users) rather than to its business logic.
• The automated process plays a role much like a human user, accessing each application as a person would. Both approaches have value. Today, though, it’s fair to say that business logic integration is more popular. Most mainstream integration products use this approach, as do typical business process management systems (BPMSs).
• In fact, the idea of service-oriented architecture (SOA) can be seen as a generalization of business logic integration.
• It can be fast and relatively easy to implement compared to business logic integration.
• No changes to the applications are required, and with the right tools, creating adapters for existing user interfaces can be straightforward.
• It can cost less than automating processes through business logic integration.
• To some degree, this is a corollary of the relative simplicity of presentation integration. It also means that presentation integration can be used with lower-value business processes.
• For example, perhaps an application’s transaction volumes don’t justify the effort and expense of business logic integration, or maybe the technical complexities of business logic integration exceed the business value of automating this part of the process. Because presentation integration is quicker and less expensive, it can make sense in situations like these.
• Because the implementation effort isn’t huge, automated processes that use presentation integration can be relatively easy to change. This is important, as many business processes are quite dynamic.
• Automated processes that are difficult to change can be worse than manual processes, since they make a firm’s operations more inflexible.
• With appropriate tools, it’s even possible for business analysts to make the necessary modifications, freeing IT staff from dealing with many small change requests.
• Presentation integration can be used to access all kinds of applications, from modern Web solutions to legacy mainframe software.
• An application doesn’t need to expose special integration interfaces.
• Think about a mainframe application, for example, that doesn’t provide any interfaces for business logic integration.
• Presentation integration can still be used to access it, since this approach requires just a terminal interface. Or perhaps an application is accessible only via a remote access technology such as Citrix XenApp or Microsoft Remote Desktop Services.
• With the right support, presentation integration can also be used to access this kind of software.
• Even processes that depend on client/server applications with extensive client logic can be automated using this approach.
• In many applications, including modern Web applications and older client/server solutions, important parts of the business logic are implemented in the user interface. On the Web, for example, data validation is frequently done in JavaScript running in the browser.
• Presentation integration takes advantage of this, something that’s harder to do with business logic integration.
