Question

How can user error be controlled? Is it unavoidable?

Answer 1

Answer)
The error can be of many types, whereas the primary areas to focus on will be human errors and computer errors. Human errors are the errors which result out of the unintentional decision or fault which occurs and thus this gives the room of the errors in the tasks which are given to the humans. The human errors can be handled, by the humans by practicing the skill set, automating the activities such that manual jobs are reduced, and checking and reviewing by peers which will introduce lesser errors.

Thus the human or user error can be deemed as unintentional, a mistake or negligence.
Thus for the control, we need to have:
Strategies which make the system detect and point out the mistake which the user is making.
Using the prevention strategies for supporting the correct execution of the tasks.
Using mitigation methods, for mitigation of the consequences fo the errors where we can detect the errors and correct the situations before they are aggravated.

Human and user error can be controlled and avoidable upto an extent but not completely. Thus these can be controlled up to an extent and thus are unavoidable.
