Queensland Government roles align with the Leadership competencies for Queensland.
Leadership competencies for Queensland describes what highly effective, everyday leadership looks like in the sector. In simple, action-oriented language, it provides a common understanding of the foundations for success across all roles. The profile describes three performance dimensions (vision, results and accountability) and 11 leadership competencies required against five leadership streams.
Leadership streams are not connected to a level or classification, but rather reflect the balance between leadership and technical skills required of an individual. Individuals can consider the ‘value proposition’ of roles rather than the traditional lens of hierarchical structures or classification levels. The five leadership streams are:
- Individual contributor (Leads self and does not supervise others)
- Team leader (leads a team and typically reports to a program leader)
- Program leader (leads team leaders and/or multiple areas of work)
- Executive (leads program leaders or other executives)
- Chief executive (leads the organisation).
When developing a role description, identify the role type and then focus on the most important attributes and create a balance between SFIA skills and leadership skills.
Most staff who work as a database administrator possess a degree in areas such as information technology or corporate systems management.
Industry experience or a diploma level qualification are also held in high regard and may be of some assistance in gaining entry to a career as a database administrator. Diploma level qualifications can generally be obtained through participation in a TAFE course.
