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 inherent data requirements of both old and upgraded or new systems. Assessment must confirm the ability to remodel data to achieve successful conversion. To demonstrate competency in this unit the person will require access to: Analysis of the source data Software development environment Technical requirements Data mappings Logic to convert the data Plan of the conversion routines Business quality assurance rules associated with data The person will need access to the data conversion plan to demonstrate competency in this unit. |
Context of and specific resources for assessment | The data conversion process should include/cover: Replacing missing data values Ensuring correct field values to match field definitions Removing unwanted duplicates Establishing storage and data presentation standards Standardising abbreviations Removing unwanted or unnecessary characters and data types Checking the consistency of data across files and testing data integrity rules Data conversion is the translation of data from one format to another. Often when data is moved from one system to another, some form of data conversion is required to convert the data to a format the receiving system can interpret. In some cases, it is even necessary to have an intermediate format before converting to final form. 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: ICAB5063B Monitor and support data conversion ICAI5096B Complete data transition 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 |
