Close your education gap by completing the all-important doctoral dissertation. That's actually what makes you a 'doctor'. If you are called by the title of a doctor, whereas you did not conduct research, you may not have the confidence to operate smoothly in the midst of doctors who conducted research.
It is a critical item in your war chest. Your university might not have subjected you to it for reasons. For example, if you did not go through the dissertation rigor, you would not command the respect of other doctors. To protect what you spent throughout your doctoral program, it would be suicidal for you to not have a dissertation published on ProQuest.
In a way, your university did you a favor by saving your time and money, and getting you out the door to answer 'doctor' as quickly as possible. At Emmanuel University, for instance, a doctoral student must take a comprehensive examination before embarking on the dissertation. Your interviewers, hirers, and employers may not tell you that the absence of a dissertation published on ProQuest (usually implied) on your CV is a problem. Seize this opportunity to stay ahead of the curve.
