Exercise 3.10 Model the following business process for handling downpayments. The process for handling downpayments starts when a request for payment has been ap- proved. It involves entering the downpayment request into the system, the automatic sub- sequent payment, emission of the direct invoice and the clearance of the vendor line items. The clearing of the vendor line items can result in a debit or credit balance. In case of debit balance, the arrears are processed, otherwise the remaining balance is paid. Exercise 3.11 Model the following business process for assessing credit risks. When a new credit request is received, the risk is assessed. If the risk is above a threshold, an advanced risk assessment needs to be carried out, otherwise a simple risk assessment will suffice. Once the assessment has been completed, the customer is notified with the result of the assessment and meantime the disbursement is organized. For simplicity, assume that the result of an assessment is always positive.

Business process models are important at various stages of the business process life cycle and before starting to model a process, it is crucial to understand why we are modeling it. First, it may be simply to understand the process and share our understanding of the process with the people who are involved with the process on a daily basis. Second, process modeling helps to better understand and to prevent issues. This step of process modeling is a prerequisite to conduct process analysis, redesign or automation. With this understanding the concepts of process modeling we will be able to produce a business process that captures simple temporal and logical relationships between activities, data objects and resources. 3.7 Further Exercises Model two (2) Business Processes 1.
