  • Unit 2: Systems interfaces assessment summary sheet

    This unit must be completed separately for each interface included in the assessment.

    For each interface:

    Fill out these tables to answer the four questions and the risk rating that you will record with your scores. Also record additional comments and document evidence for each question.

    1. Complexity

    Question 1: How complex is the interfacing between your systems?

    Possible answers (tick the ones that apply)

    Score

    Risk rating

    Low complexity – minimal data manipulation or formatting, static data mapping, simple transaction summarisation, few data sources

    3

    Low

    Medium complexity – intermediate complexity of data manipulation, data mapping based on multiple criteria, several data sources

    6

    Medium

    High complexity – multiple data sources, complex data manipulation, dynamic data mapping

    9

    High

    2. Method

    Question 2: How are your systems interfaced?

    Possible answers (tick the ones that apply)

    Score

    Risk rating

    System event triggered or automated cyclic batch update

    2

    Low

    Manually activated batch update

    4

    Medium

    Data from source system manually transposed to destination system

    6

    High

    3. Exceptions

    Question 3: How do you know if the interfacing and flow of data does not work?

    Possible answers (tick the ones that apply)

    Score

    Risk rating

    Good exception processing – pre-processing data validation step, system generated exception processing and data reconciliation and automated error alert, all in or none in record processing

    3

    Low

    Medium exception processing – no pre-processing data validation step, system generated record processing reconciliation, no automated error alert, rejected records must be managed by end-users

    6

    Medium

    Low or no exception processing – manual reconciliation required, no automated error alert

    9

    High

    4. Documentation

    Question 4: Do you have any documentation on the interfacing method and flow of data between your systems?

    Possible answers (tick the ones that apply)

    Score

    Risk rating

    Comprehensive documentation – version controlled specifications and test scripts available

    1

    Low

    Average documentation – original specifications available but no test scripts

    2

    Medium

    Poor documentation – no specifications or test scripts available

    3

    High
