Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

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 ability to:

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

Context of and specific resources for assessment

Assessment must ensure access to:

data in a DBMS

data-warehousing tool

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:

written report outlining:

cost-benefit analysis of a data warehouse implementation for a defined organisation

user guide for usage of an implemented data warehouse

technical documentation for an implementation of a data warehouse

questioning to determine knowledge of relationship between databases and data warehouses

project to implement a data warehouse.

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 non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.

Required Skills and Knowledge

Required skills

analytical skills to:

analyse business requirements

gather and analyse user requirements

technical skills to:

convert and validate data

perform data modelling

work with databases, including programming languages.

Required knowledge

business operating systems related to data sources

database management system (DBMS) fundamentals to facilitate extraction of data

decision support systems related to knowledge management strategies

encryption and authentication as they apply to database security features

functions and features of dimension tables and fact tables

installation and use of proprietary software

logical database model knowledge to facilitate data extraction.
