Elements and Performance Criteria

  1. Identify areas of poor performance
  2. Investigate methods to improve system performance
  3. Develop an implementation plan for system optimisation
  4. Modify system to optimise performance
  5. Monitor ongoing system performance

Required Skills

Required skills

Measuring system performance against predefined benchmarks

Risk analysis skills in relation to reviewing change procedures

Comprehension of technical manuals

Adequate use of diagnostic tools

Report writing and recording skills

Required knowledge

Current industrystandard hardware and software monitoring tools and the how to interpret information produced from monitoring

Broad knowledge of the role of stakeholders and the degree of stakeholder involvement

Detailed knowledge of the systems current functionality

Broad knowledge of quality assurance practices

One or more change management tools

General knowledge of system performance change control procedures and theoretical concepts

Detailed knowledge of the system under modification

Business scheduling requirements

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 following is essential

Assessment must confirm sufficient knowledge of the indicators of inadequate performance

Assessment must confirm the ability to keep the system balanced and performing well

Assessment must confirm the ability to analyse system performance

To demonstrate competency in this unit the learner will require access to

System components and software for performance tuning

Technical manuals and resources

Fault logs

Diagnostic tools

Context of and specific resources for assessment

As systems grow they can become fragmented and congested with incompatible software and unused programs which can lead to wasted CPU cycles and unnecessary overuse of RAM

The role of optimising system performance can avoid spending money on unnecessary hardware and software when all that is required is careful management of current resources

The breadth depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and nonroutine Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a nonroutine or contingency nature

Assessment must ensure

Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic

Applications may involve responsibility for and limited organisation of others

Method of assessment

The purpose of this unit is to define the standard of performance to be achieved in the workplace In undertaking training and assessment activities related to this unit consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs Additional guidance on these and related matters is provided in ICA Section

The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.

Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts This unit can be assessed either in the workplace or in a simulated environment However simulated activities must closely reflect the workplace to enable full demonstration of competency

Assessment will usually include observation of real or simulated work processes and procedures andor performance in a project context as well as questioning on underpinning knowledge and skills The questioning of team members supervisors subordinates peers and clients where appropriate may provide valuable input to the assessment process The interdependence of units for assessment purposes may vary with the particular project or scenario

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector workplace and job role is recommended for example

ICAIB Install software to networked computers

ICAI4030B Install software to networked computers

ICAIC Install and configure a network

ICAI4097C Install and configure a network

ICASB Rectify system faults on a live system

ICAS4107B Rectify system faults on a live system

ICASC Identify and resolve common database performance problems

ICAS4113C Identify and resolve common database performance problems

ICASB Undertake capacity planning

ICAS4116B Undertake capacity planning

ICASB Support system software

An individual demonstrating this competency would be able to

Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts

Apply solutions to a defined range of unpredictable problems

Identify and apply skill and knowledge areas to a wide variety of contexts with depth in some areas

Identify analyse and evaluate information from a variety of sources

Take responsibility for own outputs in relation to specified quality standards

Take limited responsibility for the quantity and quality of the output of others

Maintain knowledge of industry products and services
