The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: identify components relevant to the project requirements document component connectivity and relationships document component interface requirements. |
Context of and specific resources for assessment | Assessment must ensure access to: technical specifications organisational and process goals standards for model development computer-aided software engineering (CASE) tools project deliverables test plan project budget outcomes of the business-analysis process appropriate software and hardware appropriate learning and assessment support when required. Where applicable, physical resources should include equipment modified for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: direct observation of candidate: preparing component action diagrams conducting walk-through of models against specifications using CASE tools verbal or written questioning to assess candidate’s knowledge of interoperability between components review of developed model. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Documentation standards may include: | International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) organisational and project policy related to: sign-off storage distribution revision. |
Project specifications may include: | current system functionality technical requirements user problem statement. |
Standards may include: | ISO, IEC and AS standards organisational standards project standards. |
Requirements may refer to: | business network people in the organisation system. |
