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 communications technology, hardware, software and data modelling. Assessment must confirm the ability to translate business processes into technical processes

Assessment must confirm the ability to plan and develop a model for a physical system from the requirements

To demonstrate competency in this unit the learner will need access to:

Client requirements

The project deliverables

The acceptance criteria

Current IT blueprint

Information on a range of IT business solutions and vendor offerings

Future organisational business process requirements

Technical specifications

Context of and specific resources for assessment

The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic.

The demonstration of competency may also require self-directed application of knowledge and skills, with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others.

Assessment must ensure:

Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others. It may include participation in teams including teams concerned with planning and evaluation functions. Group or team coordination may also be involved.

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 ICA05 Section 1.

Competency in this unit should to 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 and/or 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. In the case of this unit, it could be assessed in a holistic manner with:

ICAA5054C Validate quality and completeness of system design specifications

ICAA5056B Prepare disaster recovery and contingency plans

ICAT5083B Develop and conduct client acceptance test

ICAI5100C Build an internet infrastructure

ICAA5045C Produce network architecture design

An individual demonstrating this competency would be able to:

Demonstrate understanding of a broad knowledge base incorporating theoretical concepts, with substantial depth in some areas

Analyse and plan approaches to technical problems or management requirements

Transfer and apply theoretical concepts and/or technical or creative skills to a range of situations

Evaluate information, using it to forecast for planning or research purposes

Take responsibility for own outputs in relation to broad quantity and quality parameters

Take some responsibility for the achievement of group outcomes

Maintain knowledge of industry products and services
