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.
