The literature review is the scholarly foundation of the DBA capstone project — the demonstration that the student has mastered the existing knowledge base relevant to their problem of practice, can critically evaluate the evidence that the literature provides, and can identify the specific gap or opportunity for applied contribution that justifies the capstone investigation. DB8650 develops the literature review as a capstone project component — not a broad survey of the field, but a purposeful, synthetic document that directly supports the specific capstone research questions, theoretical framework, and methodology selected in DB8640.
Constructing a synthetic literature review
Moving from annotation to synthesis in doctoral writing
- Synthesis vs. summary: DB8650 begins with the foundational skill distinction that separates doctoral literature reviews from the annotated bibliographies and research reports that students may have produced in earlier academic work. A summary literature review describes what each source says, one source at a time — a list of what individual authors have claimed or found. A synthetic literature review examines what the body of scholarship collectively demonstrates — identifying patterns of agreement and disagreement across sources, characterizing the strength and consistency of the evidence across multiple studies, noting how the field's understanding has evolved over time, and identifying the tensions, inconsistencies, and gaps that the current literature has not resolved. Synthesis requires engaging with sources in relation to each other, not just in sequence — asking "what do these sources collectively tell us about X?" rather than "what does this source say about X, and then what does that source say about X?"
- Thematic organization: The course develops thematic literature review organization — organizing the review around the key concepts, debates, and themes relevant to the capstone research question rather than around individual sources (source-by-source review) or chronological development of the field (historical review). A thematic organization for a leadership capstone might be organized around: the theoretical foundations of the relevant leadership approach; the empirical evidence on the relationship between that leadership approach and relevant outcomes; the organizational and contextual factors that moderate this relationship; the interventions and development approaches that produce change in the relevant leadership behaviors; and the specific gap in this literature that the capstone addresses. This thematic structure makes the literature review's contribution to the capstone argument clear rather than leaving readers to extract relevance from a comprehensive but unstructured survey
- Critical evaluation of evidence quality: DB8650 develops the capacity to evaluate the quality and relevance of individual studies and synthesize this evaluation across the review — not treating all peer-reviewed sources as equally credible, but distinguishing between meta-analyses and systematic reviews (the most reliable evidence on patterns across multiple studies), experimental and quasi-experimental studies (stronger causal evidence), cross-sectional surveys (weaker causal evidence, but useful for prevalence and correlation data), qualitative studies (limited to the studied context but rich in process understanding), and conceptual/theoretical papers (useful for frameworks but not empirical evidence). Capstone literature reviews that treat all sources as equally credible demonstrate insufficient scholarly sophistication
Literature review components for the DBA capstone
DB8650 develops three specific literature review components that the capstone requires. First, the topic literature review: a synthetic review of the empirical and theoretical scholarship on the specific leadership problem or phenomenon the capstone addresses. For a capstone investigating leadership development effectiveness in a healthcare organization, this would include: the evidence base on what types of leadership development experiences produce durable behavioral change; the specific leadership behaviors most important for healthcare organizational performance; the factors (organizational, cultural, demographic, individual) that moderate leadership development effectiveness; and the documented performance outcomes associated with effective leadership in healthcare contexts. Second, the methodology literature review: a review of the research designs, data collection methods, and analysis approaches that researchers have used to study similar problems — justifying the capstone's methodological choices by demonstrating alignment with established practice in the field and explaining any departures from convention. Third, the theoretical framework justification: a focused review of the selected theoretical framework's development, empirical support, and application to similar contexts — establishing that the framework is appropriate and well-supported before applying it to the capstone problem.
Connecting the literature review to the capstone argument
DB8650 develops the most sophisticated literature review skill: ensuring that the review actively supports the capstone argument rather than existing as a separate document that could have been written before the capstone project was conceived. A purposeful DBA literature review leads directly to the capstone's research questions, methodology, and expected contribution — and every theme in the review should connect explicitly to one of these elements. Literature review sections that do not connect to the capstone's specific questions, methodology, or contribution are typically unfocused — they demonstrate the student's general knowledge of the field but do not contribute to the capstone's argument. The course develops the revision skills to identify and eliminate unfocused sections, strengthen the connections between literature review themes and capstone research components, and ensure that the literature review builds toward a clear statement of the gap that the capstone will address and the contribution it will make.

Frequently asked questions
DB8650 addresses the literature review scope and length question with nuance — recognizing that "how long" is less important than "how complete" and "how purposeful." Capella's DBA capstone literature review expectations typically range from 40 to 80 pages (double-spaced, APA format), with the appropriate length determined by the complexity of the topic and the depth of literature that the research question requires. Literature reviews that exceed this range are often unfocused — including scholarship that is not directly relevant to the capstone's specific questions, framework, and methodology. Literature reviews that fall well below this range typically fail to demonstrate adequate engagement with the existing scholarship. More important than page count is coverage: the literature review should demonstrate systematic engagement with the most important scholarship on the capstone topic (not just convenient or easily accessible sources); critical evaluation of the evidence quality across sources; synthesis of what the literature collectively demonstrates rather than summary of what individual sources claim; and explicit connection of literature themes to the capstone's specific research questions, theoretical framework, and methodology. The approval-required gate at the end of DB8650 evaluates these quality dimensions rather than page count — reviewers are assessing whether the literature review provides an adequate scholarly foundation for the capstone investigation, whether the student has demonstrated doctoral-level capacity to synthesize and critically evaluate research, and whether the review leads logically and specifically to the capstone's research design.
