Develop high-level object-oriented class specifications

Assessment tool

Version 1.0
Issue Date: May 2024


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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 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.

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.

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.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

(add new lines for each of the assessment tasks)

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Assessors must satisfy NVR/AQTF assessor requirements.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
