Validate an application design against specifications

This unit describes the performance outcomes, skills and knowledge required to check the software application design against specifications and apply validation techniques across the system life cycle.

Application

This unit applies to individuals employed in the area of software development responsible for verifying and validating software-design specifications.

They may be individuals who work as software project managers, testers, software engineers, system analysts and software developers.


Prerequisites

Not applicable.


Elements and Performance Criteria

1. Evaluate software-requirement specification

1.1 Review software requirement specifications document to ensure that requirements are completely specified and correct before software design begins

1.2 Validate the software requirement specifications document

2. Create a proof-of-concept prototype

2.1 Use rapid application development tools to create prototype system

2.2 Present prototype system for demonstration to appropriate person

2.3 Validate proof of concept

3. Evaluate software design

3.1 Determine if the design is complete, accurate, consistent and feasible

3.2 Validate software design document

3.3 Validate database structure and elements

3.4 Validate user interface (UI)

3.5 Review software risk analysis

4. Evaluate source code

4.1 Validate consistency between code and software design document

4.2 Validate logical structure and syntax using static analysis tools

5. Evaluate testing requirements

5.1 Review and validate test plans

5.2 Review and validate test cases

6. Document validation

6.1 Document results of validation exercise

6.2 Recommend current software design or itemise required alterations

6.3 Submit report to appropriate person for action

Evidence Required

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:

verify and validate software application design, including:

creating proof of concept (PoC) prototype

evaluating the technical specification and comparing against the PoC

interpreting and evaluating software design documentation requirements and confirming details with the client

analysing and validating user interface and database requirements

effectively using static analysis tools

walkthrough documents, test plans and test cases.

Context of and specific resources for assessment

Assessment must ensure access to:

tools to create prototype systems

static analysis tools

test plan and test cases

appropriate learning and assessment support when required

modified equipment 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:

review of candidate’s validation documents

evaluation of validation documents.

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.


Range Statement

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.
