Application
This unit describes the skills and knowledge required to analyse requirements and produce a set of high-level object-oriented class specifications.
It applies to individuals who are required to develop object designs as part of the systems design process.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Analyse the behaviour of objects | 1.1 Analyse behaviour scenarios and the prepare documentation, according to standards 1.2 Identify classes, objects and abstract data types, according to requirements 1.3 Prepare class, object, module and process diagrams, according to specifications |
2. Prepare a state model | 2.1 Analyse data requirements and iterate data flows 2.2 Prepare state-transition diagrams, according to standards 2.3 Improve the abstract data types and specifications |
3. Describe the roles and responsibilities of classes | 3.1 Review the functional requirements, assign responsibilities and update class structures 3.2 Specify the interface and class communication requirements 3.3 Prepare the interaction diagrams, according to standards |
4. Iterate and review the object model | 4.1 Review the current object model, class functionality and data transformation 4.2 Identify and develop class relationships, priorities, and the inheritance hierarchy 4.3 Review the class-service requirements and initial test criteria 4.4 Identify object processes and reuse classes 4.5 Document the model and forward it to the appropriate person |
Evidence of Performance
Evidence of the ability to:
specify and model abstract data types
specify the interface between classes and objects
document the results.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
outline configuration management
outline current industry-accepted object-oriented methodologies
outline current program development methodologies
describe data modelling techniques
describe object-oriented analysis tools
describe quality assurance practices.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the programming and software development industry, and include access to:
the business, system and user requirement
a unified modelling language (UML) modelling tool
the appropriate learning and assessment support, when required.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Reading | 1.3, 4.1, 4.2 | Interprets, and analyses, complex technical documentation |
Writing | 1.1, 1.3, 2.2, 3.3, 4.5 | Accurately records and completes documentation according to organisational formats and protocols Writes and edits documents to ensure accuracy and consistency of information, and clarity of meaning |
Interact with others | 4.5 | Shares knowledge, information and experience openly, liaising with colleagues to achieve the best possible outcome |
Get the work done | 1.3, 3.1, 3.2, 4.1, 4.2, 4.3, 4.4 | Uses a range of digitally-based technologies to access, extract and share relevant information, in order to achieve the required outcomes Identifies technical or conceptual issues, and applies analytical processes, to resolve these issues Uses analytical and lateral thinking to review current practices, and to develop new or improved software or systems |
