Hi Larry,
Here are a few more thoughts for you:
I tend to agree with Guy that "Maintain Customer Data" is probably not a process. Why? You'll have to do some more detailed study on your own as to what is the definition of a business process, but in general a business process must have a clear business objective. It's not clear to make what the business objective is for "Maintain Customer Data". My gut feeling tells me that "Maintain Customer Data" is a task (or sub-process) but of a larger business process. You should identify the high-level (aka key) business processes first. In addition, for each high-level business process you should be able to describe/define the process using a short paragraph (from the business perspective.
For example: "Originate Loan" is a business process in the mortgage industry. The business derives value from this process because for every loan which is funded the business makes money. The high-level definition might be like this: "Originate Loan" is the process (set of activities) by which a mortgage company interacts with prospective borrowers in order to provide them with a mortgage product which meets their specific need.
Since you are new and do not have a preference towards a given tool/methodology, I would suggest that you take a look at BPMN (Business Process Modeling Notation) as a way to model your business processes.
BPMN.org has the details on the specification and a number of useful articles and guides for using BPMN.
Also, take a look at Active Modeler as they provide a version of their tool for FREE. Active Modeler supports BPMN. Also, there is a stencil available for Microsoft Visio if you already use that tool within your organization.
