IBM has been a market leader in BPM space and supported largest single customer segments the
U.S. federal market (for example, the Department of Defense Architecture Framework, the
Treasury Enterprise Architecture Framework and the Federal Enterprise Architecture Framework)
in which System Architect(SA) has long been the dominant player.
Later, with the divestment of SA, IBM developed a new BPM platform “IBM BPM” which is a
comprehensive business process management platform. It provides a robust set of tools to author,
test, and deploy business processes, as well as full visibility and insight to managing those
business processes.
Although building user interface forms in IBM BPM Process Designer was simple enough for
business people to use in previous versions, the latest version of IBM Business Process Manager
now requires substantially more technical expertise. Which limits the agility for composing model-driven process-oriented applications, including a full function run-time environment with
specialized engines for application execution and monitoring.
IBM Business Process Manager does not include a repository tool for relational database
modeling, and if this is a requirement, a third-party tool must be purchased separately.
End users only see and perform the tasks assigned to them or to their assigned groups based on the
process model’s design. Although business users select, execute, re-assign, delegate and escalate
tasks similarly like in other BPM tools, but the user experience is limited as collaboration between
business users is not as robust compared to the workflow in other BPM platforms.
Integration Designer in IBM BPM is not tightly integrated with the rest of the IBM BPM
architecture. Unlike IBM’s Process Designer tool which adds every artifact immediately to
Process Center’s BPM Repository database when a project is saved, Integration Designer stores
artifacts on a developer’s local machine.
IBM Process Server’s deployment and execution of BPMN and BPEL processes is limited. As
IBM Business Process Manager work item instances travel through processes at runtime,
execution occurs in two dissimilar ways. Process Designer BPMN processes execute using
interpreted code read from the BPM Repository database. The services and BPEL processes
created in IBM’s Integration Designer, on the other hand, are deployed on Process Server and are
executed as compiled code on the application server. The overhead of BPMN process interpreted
execution and its frequent database access adversely affects IBM Business Process Manager’s
performance and limits its management and administration.
