The task decision matrix below is a tool for airport managers and decision-makers to utilize when evaluating the appropriate training or qualifications needed for work on certain airfield electrical projects. In the absence of staff experience as described, the matrix provides options for training which may be used to up-skill airport electrical workers. Task complexity begins in Tier 1 at the bottom of the matrix with relatively simple tasks. Task complexity and associated training and experience needed to conduct various procedures increases in conjunction with higher tiers.

If there is any uncertainty about a task and appropriate electrical experience needed to conduct a procedure, managers should always exercise caution and consult the component manufacturer or a suitably qualified professional.
