Throughout the committee duration, proposed changes are documented and screened by the Chairperson. He / she determines which suggested changes might be necessary, and these are investigated to determine the impact of accepting or rejecting them. When the investigation is complete, the change is either approved and the committee plan is adjusted to reflect this decision, or the change is rejected giving justification.
Generally, anyone in the committee (or from outside) may submit a change request. The Chairperson has the ultimate authority to approve or reject change requests. However, if the change appears to impact the GDA strategic goals, the change request should be escalated to the GDA Technical Manager.
