Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Use of SQL

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.

System configuration may include:

Operating system: Novell NetWare 5 or above or operating system that has multi-user ability; Linux, Mac OS, Windows 2000 or above

Database software: Oracle, Sybase, Microsoft SQL Server, Ingres, DB2, Informix, mSQL, MySQL, SQL server

Configuration: small memory model, large memory model, requests per second

Securityplan may contain strategies for:

handling theft

viruses

standards (including archival, back-up, network)

privacy

audits

alerts

usually relates directly to the security objectives of the organisation

System may include but is not limited to:

databases

applications

servers

operating systems

gateways

application service provider

ISP

Users may include:

a person within a department

a department within the organisation

a third party

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
