Section D: Practical Questions
[20 Marks]
Question 1: Model the following fragment of a business process for assessing loan
applications.
[10 Marks]
A loan application is approved if it passes two checks: (i} the applicant's loan risk assessment,
done automatically by a system, and (ii}the appraisal of the property for which the loan has
been asked, carried out by a property appraiser. The risk assessment requires a credit history
check on the applicant, which is performed by a financial officer. Once both the loan risk
assessment and the property appraisal have been performed, a loan officer can assess the
applicant's eligibility. If the applicant is not eligible, the application is rejected, otherwise, the
acceptance pack is prepared and sent to the applicant.
Question 2: Calculate the cycle time for the process below.
