Development Depth: Your Committee Wants to Know HOW, Not Just WHAT

Flagged in 5-8% of paragraphs we analyze. Stating a finding without explaining the mechanism behind it is like citing a destination without giving directions.

FIX

Expand this claim to explain HOW or WHY the mechanism works.

What This Issue Is

Development depth is the difference between reporting and analyzing. When you write "Transformational leadership improves employee retention," you've stated a finding. Your committee's immediate question is: How? Through what mechanism? Under what conditions? Your job isn't just to tell them what researchers found—it's to explain why it matters and how it works.

This is the hallmark of doctoral-level writing that separates it from a master's thesis. At the master's level, you can get away with: "Studies show X leads to Y." At the doctoral level, your committee expects: "X leads to Y through the mechanism of Z (Smith, 2020), particularly when A and B conditions are present (Jones, 2021)." You're expected to unpack the black box, not just point at it.

Underdeveloped claims often cluster in the literature review's middle sections, where fatigue sets in and writers start summarizing rather than analyzing. If you find yourself writing a series of "X is important" or "Y is effective" statements without explaining the underlying logic, you've fallen into surface-level reporting. Your committee will write "expand" or "develop further" in the margins.

Why Your Committee Flags It

Claims that lack mechanism or justification read as unsupported assertions. Committees expect you to demonstrate understanding, not just awareness.

Why Students Get This Wrong

Students mention a concept and move on, assuming the reader understands its significance. They've internalized the importance through months of reading but forget to make it explicit.

Think of it this way

For every key claim, ask: "Have I explained HOW this works and WHY it matters?" If you've only stated WHAT, you've only done one-third of the work.

Before & After Examples

Before

Technology improves student outcomes.

After

Technology improves student outcomes by enabling personalized learning paths that adapt to individual progress (Garcia, 2022).

Surface-level claim expanded with the HOW mechanism and a connecting insight.

Before

Professional learning communities improve teacher effectiveness.

After

Professional learning communities improve teacher effectiveness by creating structured opportunities for collaborative lesson planning, peer observation, and evidence-based reflection on practice (DuFour & Eaker, 2020), which breaks the isolation that typically characterizes classroom teaching.

Vague causal claim developed with specific pathways and bi-directional explanation.

Before

Self-efficacy influences academic achievement.

After

Self-efficacy influences academic achievement through two pathways: students with higher self-efficacy set more challenging goals and persist longer when encountering difficulty (Bandura, 1997), while low self-efficacy leads to task avoidance and learned helplessness (Pajares, 2006).

"Is important" replaced with the specific mechanisms that explain WHY it matters.

Before

Cultural responsiveness is important in education.

After

Cultural responsiveness improves learning outcomes because it reduces the cognitive load of code-switching (Gay, 2018) and increases student engagement by validating identity and prior knowledge as assets rather than deficits (Ladson-Billings, 2014).

Frequently Asked Questions

Adding words doesn't equal adding depth. You can write a 300-word paragraph that just repeats the same claim with different citations. Development depth means explaining the mechanism (HOW something works), the conditions (WHEN it applies), and the reasoning (WHY it happens). A well-developed paragraph unpacks the logic, not just the evidence.
Apply the "so what" test. After every claim, ask: "So what? Why does this matter? How does this work?" If you can answer those questions from what you've written, your analysis is probably deep enough. If the answers are only in your head and not on the page, you need to develop further.
Descriptive writing tells the reader WHAT exists or WHAT researchers found. Analytical writing explains WHY it exists, HOW it works, and WHAT IT MEANS in the context of your study. If your literature review reads like a series of research summaries, you're being descriptive. To be analytical, connect every finding to a mechanism, a pattern, or an implication for your research.
Focus your deepest analysis on claims that are central to your theoretical framework, research gap, and research questions. Supporting claims can be developed more briefly. Think of it like a pyramid: your core arguments get full development with mechanisms and conditions, while peripheral points get a sentence or two of context. Your committee expects depth where it matters most.
