JBoss BRMS Best Practices - Tips for your BPM Process Implementation Layer
The Agile Zone is brought to you in partnership with JetBrains. Learn how Agile Boards in YouTrack are designed to help teams plan, visualize and manage their work in an efficient manner, with support for both Scrum and Kanban processes.
I have posted some articles in the past on migration strategies, taken closer looks at process layers and provided some best practices for jBPM, both touching on very specific parts of your BPM strategies. I wanted to revisit the topic of best practices but then on an Intelligent, Integrated Enterprise level where we talk about getting control over your business processes with JBoss BRMS.
To start with we need to take a closer look at the landscape and then peel back the layers like an onion for a closer look at how we can provide BPM projects that scale well. Figure 1 shows that there are several component layers where we will want to focus our attention:
- Process Initialization Layer
- Process Implementation Layer
- Process Repository
- Tooling for business users & developers
- Console, reporting & BAM dashboards
- Process Interaction Layer
|Figure 1: Enterprise BPM landscape.|
The process implementation layer which will be covered here is where the processes are being maintained, with help from the process repository, tooling, business users and developers that design them. Here you will also find the various implementation details, such as domain specific extensions to cover specific node types within our projects.
The console, reporting and BAM dashboard components are the extended tooling used in projects to provide business value or information that can be used to influence business decisions. Best practices in this area will be covered at a later time.
Finally, the process interaction layer is where you processes will connect to all manner of legacy systems, back office systems, service layers, rules systems even third party systems and services. Best practices in this area will be covered in a later article.
Process Implementation Layer
This article briefly walks through the high level BPM architecture and lays out the various layers of interaction. The implementation layer is examined to provide some insights into best practices within this layer. The main focus is the SKS where we suggest how to not only use, but manage process instance life-cycles within a single service. On top of this it is suggested that this is a good entry point to offload your BAM events. There is still more to take a look at in future articles, in the Process Interaction Layer, in the Process Repository, in the Tooling and in the reporting & BAM layers.
