Prepare for your future in IT by advancing your knowledge base and leadership skills with our online Doctor of Information Technology degree program.
Walden students have up to 8 years to complete their doctoral program unless they petition for an extension.
In general, students are continuously registered in the dissertation/doctoral study course until they complete their capstone project and it is approved. This usually takes longer than the minimum required terms in the dissertation/doctoral study course shell.
To complete a doctoral dissertation/doctoral study, students must obtain the academic approval of several independent evaluators including their committee, the University Research Reviewer, and the Institutional Review Board; pass the Form and Style Review; gain approval at the oral defense stage; and gain final approval by the Chief Academic Officer. Students must also publish their dissertation on ProQuest before their degree is conferred. Learn more about the dissertation/doctoral study process in the Dissertation Guidebook.

In this course, students develop skills in descriptive statistics, statistical inference, and quantitative techniques, including correlation, t-tests, ANOVA, regression, and various non-parametric methods. Students use quantitative data reduction and analysis and data management techniques, and they learn to utilize software for data analysis. This course is not intended for students to become fully grounded in statistical methods; rather, students learn appropriate questions to ask about data analysis, as well as how to defend their use of specific techniques in professional practice.
Students taking this course have the opportunity to extend their research and general analysis skills as they further explore research methods and project types—specifically, qualitative and case study research methods—that they may incorporate into their own doctoral study. Students explore ways of improving the quality and strategic analysis of organizational information technology (IT). They also focus on how to think in an action-oriented manner, as if they were consultants, so that their own doctoral study work could be applied in action. Finally, students begin to plan their doctoral study by engaging in an iterative process to develop their premise and a draft prospectus that incorporates feedback from peers and the course instructor. Ultimately, students offer the prospectus as a document for review and consideration by potential mentors for their doctoral study.
