The move signals an attempt to fashion the portal as a hub for critical processes that span multiple applications and services across the enterprise.
IBM is developing an embedded component technology for its WebSphere Portal that is designed to deliver specific back-end services into a portal application or a process.
Scheduled for release next year, WebSphere Portal 5.0 will include the first set of browser-based components that allow portal users to call basic productivity services such as spreadsheet, word processing and presentation views into a portal-based process.
"If you have a process where a spreadsheet needs to be called, wherever you are in a particular process, you can have the portal make a call to those services," said Larry Bowden, vice-president of IBM portals. "The portal is a great mechanism to have a bunch of services just sitting in the back waiting to be called by particular applications."
Plumtree Software is also readying a business process engine for release. Its Fusion software is designed to allow portal users to create processes that span multiple systems, including portal, content management, identity management, search and business process automation.
The releases point towards the evolution of portals beyond mere platforms for application viewing and access and towards the facilitation of true cross-application integration, according to RedMonk analyst Stephen O'Grady.
"Giving someone a single interface that not only aggregates information and lets you interact with the application but also lets those applications talk to each other within that interface [is] really introducing a whole new value proposition," O'Grady said. "This is getting into offering business process management and advanced workflowlike capabilities through the portal framework."
Another key value of process-rich portals is the ability to hide back-end complexity from users, said Nate Root, analyst at Forrester Research.
"The portal helps solve the chaos of tools all over the [organisation] by putting them in a toolbox, but it is still confusing for users because there are thousands of tools in the box," Root said.
"The way process portals improve is to take the toolbox method and sift out certain tools that are common in certain tasks and organise them, wrap instructions around them and automate around them so it is easy for employees to digest."
Portal vendors BEA Systems, Corechange and Vignette, which recently acquired the Epicentric portal, are also staking ground in the fledgling process-portal market.
In the next version of its WebLogic Portal due next year, BEA plans to provide a more tightly integrated portal, business process management (BPM) and development environment to facilitate process development and delivery within the portal, said Pat O'Haren, senior director of product management at BEA.
"Process portals are not just a matter of having a number of technologies like portal and BPM available," O'Haren said. "It is [a matter of] how you bring them together so you can easily create those portals and deploy them."
Corechange recently rolled out software designed to let business users create and manage automated business processes through its Coreport portal framework. CoreProcess uses Web services standards such as UDDI, WSDL, and Soap to map a business process and integrate with back-end systems.
CoreProcess puts business users in control of processes by letting them model a business process in the portal that uses and reuses existing application infrastructure.
Vignette, meanwhile, is looking to combine its strength in content management (CM) with Epicentric's portal framework to exert control over content as it moves across multiple processes and applications.
With Vignette V7's integration, aggregation, and process management capabilities, Vignette sees a key advantage in the ability to track process content as it flows through the organisation, said Jeff Montgomery, senior product marketing manager at Vignette.
"The portal gives the ability to proceed though a business process, and having a CM and process management system behind the scenes lets you understand how the information is used, where it is in its life cycle and how it relates to the overall business process," he said.
BPM technology vendors are also eyeing synergistic links between portals and business process.
Enterprise software specialist HandySoft, which touts its BizFlow product's ability to incorporate human users into system-to-system process flows, views the portal as a natural interface to kick off processes.
"BPM could be the missing link in portals," said Daryn Walters, vice-president of worldwide marketing at HandySoft. "We think that there's a lot of synergy there."
HandySoft recently shifted its strategy to offer not only a core BPM platform but also pre-built solutions for particular industries such as banking and insurance. Among the components of the BizFlow Accelerator Suite is a portal-based UI.
Fujitsu, meanwhile, is in the process of wrapping up several disparate products, including i-Flow BPM software and its enterprise portal, into a unified suite.
The new InterStage platform also features an application server and content server, according to Charlie Chang, vice-president of sales and marketing at Fujitsu.
I-Flow's process modelling interface is browser-based, enabling it to be accessed from within a portal, an example of the kind of synergy Fujitsu is seeking by tying its infrastructure pieces together.
Chang also said the growing need to manage and execute the flow of Web services would necessitate linkages between BPM, portals and other integration pieces.
"We feel strongly that Web services orchestration layers are going to be integral to the next wave of integration," said Chang. "And by that, we are talking about a convergence of BPM and application integration and portals."
