SKILL
|
DESCRIPTION
|
|
Numeracy
|
- Applies knowledge about space and shape, including angle properties, when analysing variables
- Applies knowledge about space and shape, including angle properties, when analysing variables
- Determines link budgets by selecting antennae size, power requirements, link availability and bit error rate (BER) by solving complex mathematical formulas
|
|
Reading
|
- Interprets complex technical information in a variety of forms and applies the knowledge gained to solve complex problems by making informed judgements and assumptions
|
|
Writing
|
- Uses clear, specific and industry related terminology to prepare detailed reports containing recommendations for relevant personnel
|
|
Planning and organising
|
- Analyses data and seeks feedback to improve plans and processes
- Makes high impact decisions in a complex and diverse environment, using input from a range of sources
- Identifies key factors that impact on decisions and their outcomes, drawing on experience, competing priorities and decision-making strategies where appropriate
- Operates from a broad conceptual plan, developing the operational detail in stages, regularly reviewing priorities and performance during implementation, and identifying and addressing issues as the work progresses
