Hi Masaiculin,

While the seasonal posters up on this forum will encourage you to research more about *your* requirements before deciding on whether you want to have an inhouse system, an external development effort or just simply an commercial-off-the-shelf product (like you mentioned before). 

In a direct answer to your question, there are many vendors who are offering BPM solution set like that under different names (Business Process Management, Business Process Engineering Language, Enterprise Service Bus Process Suite ...etc - you can go crazy with names !). But basically, it will have to depend on your requirements and the nature of your industry. The nature of the requirements (workflow with content management centric, business intelligent centric, workflow centric, erp centric ...etc) and the industry (education, retail, transactional ...etc) could greatly affect your technology of choice. 

Apparently from the requirement above (it's a hasty conclusion i know), you seem to interest in electronic content management workflow management process. You can check out Oracle Fusion Middleware Suite, IBM Websphere Suite, Tibco, ASG Software, i know SAS has some similar offering with a more analytical touch. 

Basically, start first with IBM and Oracle, see how that goes. 

Look at Blackline or AWD or Hyperian
