As the BA works through the process, s/he will encounter interactions with services that may or may not exist. In a significant portion of enterprises, there will not be a catalogue of every business service that has been implemented, let alone every one that could be desired. Rather than stopping at each case of need of interaction with a business service, the BA could 'simply' define the interface as the business process sees it and support it with a quick and dirty database (a bit like using MS Access to deliver you operational support systems because it takes too long to get the necessary work done with SAP). Using Intalio, MySQL and a bit of AXIS generation the BA could refine the business process with a working example (I suspect that this may fit within the Agile manifesto). At the point that the working solution satisfies the business for flow, it could be handed over for technical improvement. (integration into the normal pattern of user interface - say MS Outlook or Facebook; and integration into the back office systems of CMS and Finance). For the enterprise, there is a risk associated with this approach ... the initial delivery may become operational and valuable enterprise level information remain hidden from the organisation as a whole (very much as happened with the general use of Access databases).
Jacques-Alexandre Gerber covered this aspect in a post
I suggest that step 3 in most cases should not need a propeller-head 'IT Engineer' but a sandpit and toolset for the BA to work with ideas about what the service should look like at that point. Generally, a simple database will do the job for a business process emulation but more exotic plug-ins may evolve in this space (for example instant-messenger presence behavior).
To summarize, here is how simulation and emulation can be envisioned to be used in order to indeed provide valuable business information before deploying processes in a production environment:
- Business Analysts create new process models in Intalio|BPMS Designer
- Business Analysts use Intalio|BPMS Designer simulation capabilities to ensure their process models meet their objectives and requirements as far as they can tell.
- IT Engineers add emulation processes and deploy them in the emulation environment.
- Business Analysts analyze the business reports they get from the emulation environment.
- Based on the reports, Business Analysts may revisit their models and go back to step #2. Once they are happy with the business outcome they can truly expect to get, it’s time to actually implement those processes.
- IT Engineers now fully implement processes by integrating external systems and users. The next steps are the traditional steps to deploy an application in a production system (test, acceptance, production)
The world does not stand still so the effectiveness of the business process should be measured in production. This is where the BPMS really pays off, as the throughput and utilisation of every activity is automatically gathered and available for analysis. The cycle then resumes at step 2 with improvement in process.
Somewhere in the development cycle, some human-factor engineering needs to take place. If the enterprise has a particular style of working with information "the way we work here", then the BA tool-set could include some helpers here. For example, if the culture is to manage personal tasks through Outlook task lists then providing the task management user interface through an OBA.
If you are faced with inertia in database and enterprise services then building solutions with CRUD services delivered out of the business process delivery seems a good way of establishing what the business requirement is, and what the value will be without having to deal with the triage mechanisms that stand in your way.
