Answer:
Failure to communicate effectively with others affected by the decision.
Step-by-step explanation:
The new computer software that Erin chose might have been good or bad for the organization. A notable flaw in her decision making was informing the employees of the new software and possible educating them on it.
Since the decision involved others, Erin should have properly communicated the outcome of her research to others involved so that they can anticipate it and even offer their suggestions. Failure to do all of these caused the several complains by the employees.
