Informatica Business Process Manager is easy to use and learn. 

Our requirement is to orchestrate. We talk to different integration points in our client's systems and get the data from different APIs. Data gathered is enriched/cleansed and filtered with application of business rules . Output of application can be a communication sent out to clients customer via different channels or an update to their core data elements via API

There isn't any human touch involved. It's just an automated business process to build different applications and talking to various APIs using the client's ecosystems. Human workflow feature of this tool has not been explored.
