EVIDENCE GUIDE
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 the ability to successfully undertake all activities from proposal to implementation stage for a data warehouse model that reflects current and future business requirements and the business knowledge management strategy.

To demonstrate competency in this unit the person will require access to:
LAN with a relational database management system
Internet connectivity tools
Computers configurable as information servers
Proxy server software
Specialised internet security software
Business requirements
Enterprise knowledge management strategy
Context of and specific resources for assessment
Data and data mining are essential for a variety of operations related to government needs and business requirements. Extrapolating the right data for a scenario can allow for targeted resources to meet determined needs.

Creating a data warehouse requires depth and complexity involving analysis and planning across a broad range of technical and management functions.

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.

Assessment must ensure:
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.

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 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, for example:
ICAA5139B Design a database
ICAA5147B Determine suitability of database functionality and scalability
ICAA5151B Gather data to identify business requirements
ICAA5153B Model data objects
ICAA5154B Model data processes
ICAB4170B Build a database

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

Additionally, an individual demonstrating this competency would be able to:
Demonstrate an understanding of data warehousing concepts, with depth in some areas
Diagnose and design appropriate date warehousing solutions
Demonstrate accountability for outputs
