Elements and Performance Criteria

1. Determine software fault to be corrected
   • Collect and review software fault details from sources
   • Obtain technical data to assist in identifying problem
   • Clarify nature of the problem with appropriate person where necessary
2. Identify and isolate fault
   • Review program documentation for specific modules in order to pinpoint problem areas
   • Review source code for logic errors
   • 2.3 Read manuals, help files and 'read me files' to determine if there is a known fix
   • Undertake additional testing to identify or duplicate fault
   • Escalate difficult faults that cannot be identified
3. Design fix for fault
   • Ensure requirements to fix the fault are understood by client
   • Consider alternative options and choose the most effective solution
   • Consider the possible impact of the fix on other parts of the system
   • Document changes according to organisational guidelines
4. Carry out fix to software
   • Identify and obtain access to appropriate software development tools, source code and libraries
   • Construct appropriate code to correct the fault according to organisational and programming standards
   • Compile or regenerate code for changed programs and associated modules
   • Correct and resubmit code until error free
   • Document changes according to organisational and programming standards
5. Test fix and associated system areas
   • Check logic to ensure that it works with test data, corrects original fault, and does not cause problems elsewhere
   • Request users to perform acceptance testing and record outcomes
6. Hand over to systems operations area
   • Update documentation to reflect all changes made
   • Confirm acceptance by systems operations and arrange for sign-off according to procedures

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 effectively maintain custom software apply a fix that works deploy a possible range of solutions to produce the same results
Context of and specific resources for assessment	Assessment must ensure access to fault logs and helpdesk reports software development tools documentation and environment source code and libraries 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 evaluation of completed code review of candidates updated program documentation verbal or written questioning to determine candidates understanding of impact of changes on applications and systems programming standards
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 nonEnglish 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.

Technical data may be obtained from:	error messages memory dumps software traces other information.
Appropriate person may include:	authorised business representative client supervisor.
Documentation may follow:	audit trails International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) standards maintaining equipment inventory, client training and satisfaction reports naming standards project-management templates and report writing version control.
