Elements and Performance Criteria

Identify areas of poor performance
- Collect system performance data, during various usage conditions and times, using available technical tools
- Evaluate the collected system performance data related to organisational benchmarks and client feedback to identify areas of poor performance
Investigate methods to improve system performance
Develop an implementation plan for system optimisation
Modify system to optimise performance
Monitor ongoing system performance
- Implement and maintain a performance register
- Review and assess benchmarks and performance regularly with the work team to enable timely optimisation and updates

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

identify inadequacies in system performance

analyse system performance

tune the system to keep the system balanced and performing well

Context of and specific resources for assessment

Assessment must ensure access to

system components and software for performance tuning

technical manuals and resources

diagnostic tools

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

direct observation of candidate performing system tests

verbal or written questioning to assess candidates knowledge

review of documentation recording system optimisation process

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.

Tools may include:	electronic test equipment: data analyser oscilloscope voltmeter software.
System performance may be related to:	allocation of files across disk space disk speed I/O channel availability imbalances in disk use and available space memory availability and use number of concurrent users physical limitations of system poor design in a programs processor use queue depth seek time work load.
Client may include:	employee external organisation individual internal department.
Improving performance may include:	load balancing between servers or other network devices using switches or routers reducing total load by tuning the operating system tuning applications to reduce the load they impose tuning the disk sub-system using various system tools to adjust system parameters, including hardware or software upgrade.
Appropriate person may include:	authorised business representative client project manager supervisor.
Components may include:	CD and DVD drives central processing unit (CPU) complementary metal oxide semiconductor (CMOS) battery fax or modem cards interface cards motherboards random access memory (RAM).
Organisational guidelines may include:	communication methods content of emails dispute resolution document procedures and templates downloading information and accessing particular websites financial control mechanisms opening mail with attachments personal use of emails and internet access virus risk.
Documentation may follow:	audit trails International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) naming standards project management templates report writing principles version control.
