"Thank you for this opportunity. Over the past [X years], I've investigated [research topic] because [motivation]. My research asked [RQ1], [RQ2], and [RQ3]. Using [methodology] with [sample size] participants, I found [headline finding]. This contributes to [field] by [novel contribution]. In the next 20 minutes, I'll walk you through my journey and findings."
"In conclusion, this research contributes [X] to our understanding of [topic]. The key finding that [headline result] challenges/extends previous work by [how]. For practitioners, this means [practical implication]. While limitations exist in [area], these open opportunities for future research in [direction]. I'm grateful to my committee for their guidance and welcome your questions."
"Can you explain what you mean by...?"
Strategy: These are softballs. Answer clearly and concisely.
Example responses:
"Why didn't you use [alternative method]?"
Strategy: Acknowledge the alternative, explain your rationale.
Patterns:
"How does this relate to [theory you didn't cite]?"
Strategy: If you know it, connect. If you don't, be honest.
Patterns:
"What's the practical significance?"
Strategy: Be specific about who benefits and how.
Patterns:
"This seems like a significant limitation..."
Strategy: Own it, contextualize it, show awareness.
Patterns:
"I fundamentally disagree with your premise..."
Strategy: Stay calm, acknowledge the perspective, defend with evidence.
Patterns:
DBA defenses emphasize practical contribution over pure theory:
| DBA Focus | PhD Focus |
|---|---|
| Business problem solved | Knowledge gap filled |
| Industry applicability | Theoretical advancement |
| Practitioner audience | Academic audience |
| "How can organizations use this?" | "How does this extend theory?" |
Problem-Practice Link
Methodological Justification
Impact Questions
Some academics may challenge practitioner research validity:
Challenge: "Your proximity to the subject introduces bias."
Response: "Practitioner research embraces insider perspective as a strength, not flaw. I've been transparent about my position and used [techniques: member checking, reflexive journaling, triangulation] to ensure rigor. My proximity enabled access and insights that an outside researcher couldn't achieve."
For dissertations involving scale or instrument development:
Construct Validity
Sample & Power
Statistical Choices
Theoretical Framework
| Statistic | What They Might Ask | Preparation |
|---|---|---|
| CFI/TLI | "Why is .95 acceptable?" | Know cutoff debates, cite Hu & Bentler |
| RMSEA | "Your CI is wide..." | Explain sample size impact, interpret honestly |
| Factor loadings | "This item loads at .42..." | Know threshold justification, discuss retention decision |
| R² | "Only X% variance explained?" | Compare to prior studies |
| Technique | How To |
|---|---|
| Box Breathing | 4 sec inhale, 4 sec hold, 4 sec exhale, 4 sec hold |
| Power Posing | 2 minutes in expansive posture (private) |
| Visualization | Mentally rehearse successful defense |
| Grounding | 5-4-3-2-1: 5 things you see, 4 hear, 3 touch, 2 smell, 1 taste |
Acceptable responses:
| Outcome | Meaning | Next Steps |
|---|---|---|
| Pass | Congratulations, Doctor! | Minor formatting, submit final |
| Pass with Minor Revisions | Most common | 2-4 weeks of edits, advisor approval |
| Pass with Major Revisions | Significant work needed | 1-6 months, committee re-review |
| Revise and Resubmit | Fundamental issues | Major rewrite, new defense |
| Fail | Extremely rare | Discuss options with advisor |
