The flowchart begins with Start call, followed by Introduction and explain necessity for the call. The flow then branches to six responses: Person is stressed and overloaded on work; Person wants to schedule a call back; Person was not able to follow the commands due to lacking skills; Person wants a business email as form of proof; Person was sceptical of attackers identity and motive; and Person wants to be informed via mail before complying. Multiple arrows connect these responses to six strategies: Reassure that it is very fast and no hassle; Convey that it is stressful for the attacker to do the calls and there are several more to call; Establish authority and explain that the task has to be done; Give specific advice tailored to earlier problems encountered; Explain why the task has to be fulfilled and the consequences if not; and Convince that further formal information will be sent later on. These strategies connect through multiple arrows to six follow-up actions: Explain that there is a time constrain; Try to get exchanged to a co-worker; Adhere to the persons guilt of creating more work for the attacker; Give general I T advice without gathered information; Remind that the call is tasked from a managing authority and only the task is being done; and Explain that there is no known alternative and the call is the planed way.Most common interaction obstacles and persuasion techniques
