Introduction chapter by the numbers
- 10% — typical proportion of total dissertation word count allocated to the introduction.
- 1,000 to 1,500 words — master’s dissertation introduction; 7,000 to 10,000 for PhD.
- 6 mandatory components — hook, problem, question, contribution, definitions, thesis map.
- 67% of examiners report that introductions are read more carefully than other chapters because they set expectations for the whole thesis (UKCGE Examiner Survey, 2024).
- 12 minutes — typical first-read time for an introduction chapter, longer than for any non-discussion chapter.
The 6-section structure
| Section | Purpose | Words (1,200 word intro) |
|---|---|---|
| 1. Hook + context | Real-world relevance; why this matters now | ~150 |
| 2. Research problem | The specific gap or unresolved question in the field | ~200 |
| 3. Research question + objectives | Your specific RQ and 3–5 objectives | ~200 |
| 4. Contribution statement | Theoretical, methodological or practical contribution | ~200 |
| 5. Key terms / definitions | Operational definitions of central concepts | ~250 |
| 6. Thesis structure | Chapter-by-chapter signposting | ~200 |

PhD-qualified writers in your subject. Strong hook, clear problem statement, defensible contribution claim.
The hook — your first 150 words
The hook establishes that your topic matters in the real world. Strong hooks share three features: they cite a concrete fact or statistic, they reference a current problem or shift, and they connect directly to your research question. Avoid these weak openings:
- “Since the dawn of time…” — overly broad; signals lack of focus.
- “In today’s modern world…” — cliché; markers skim past.
- “This dissertation aims to…” — premature; build context first.
- Dictionary definitions — “Marketing is defined as…” — establishes nothing your reader doesn’t know.
Strong hooks open with a statistic that frames your problem, a specific recent event that illustrates the issue, or a policy or industry shift that creates urgency.
Example 1 — Master’s marketing dissertation introduction (opening)
This persistent gap between sustainability awareness and purchase intention forms the empirical puzzle this dissertation addresses. Drawing on Source Credibility Theory (Hovland and Weiss, 1951; updated Pornpitakpan, 2004) and recent work on influencer authenticity (Liu et al., 2023; Brennan, 2024), I argue that perceived authenticity of the message source — not the message content alone — mediates the relationship between sustainability claims and Gen Z purchase intention.”
This opening does six things: anchors with concrete numbers (UK market growth, conversion rate), names a current real-world problem (the awareness-conversion gap), introduces the theoretical lens (Source Credibility), establishes the research focus (Gen Z), names the central mediating concept (authenticity), and previews the contribution.
Articulating the research question and objectives
The research question is the single sentence that drives the entire dissertation. It should be specific, novel, feasible, ethical and relevant (the FINER framework — see our research proposal guide). Objectives operationalise the question into 3–5 measurable steps.
Example structure:
Objectives:
1. To synthesise the literature on influencer authenticity, sustainability marketing and Gen Z consumer behaviour.
2. To test the mediation model using survey data from 320 UK consumers aged 18 to 26.
3. To explore the mechanisms underlying the quantitative findings through 12 in-depth interviews.
4. To compare findings against existing Source Credibility Theory and refine the model where evidence warrants.
5. To propose practical implications for sustainable fashion brand managers.”
The contribution statement
Examiners want to know early what your dissertation adds. Five contribution types — name yours explicitly:
- Confirmation in a new context — extends an existing theory to a new population, setting or time
- Theoretical refinement — adds boundary conditions, moderators or mediators to existing theory
- Theoretical integration — links two previously separate theories or fields
- Empirical challenge — disconfirms a previously dominant view with new evidence
- Methodological contribution — develops a new measurement instrument, design or analytical approach
A clear contribution statement in the introduction sets examiner expectations for the whole thesis. Vague claims (“this dissertation contributes to the literature on X”) signal weak conceptualisation; specific claims (“this dissertation extends Source Credibility Theory by specifying authenticity as the active mediator in Gen Z sustainability contexts”) signal precise thinking.
The thesis structure section — signposting
The final section of the introduction provides a chapter-by-chapter map. Format options vary: bullet list, numbered paragraphs, or short flowing paragraphs. Length: 200–300 words for a master’s dissertation. Each chapter gets 1–3 sentences describing its purpose and contribution to the overall argument.
Worked examples from other disciplines
Example 2 — Nursing (BSc dissertation, KCL) — opening
“The UK National Health Service has invested over £1.2 billion in nurse-led primary-care clinics since 2019 (NHS England, 2024), yet evidence on hypertension management outcomes remains fragmented across small single-site studies (Smith et al., 2022; Jones, 2023). No multi-site UK study has compared nurse-led with GP-led management at the practice level using routinely-collected data. This dissertation addresses that gap…”
Example 3 — Law (LLM dissertation, SOAS) — opening
“The 2023 ruling in Trail Smelter Revisited by the International Court of Justice reopened a doctrinal question that the original 1941 award had appeared to settle: whether state responsibility for transboundary environmental harm extends to non-state actors operating from a state’s territory. This dissertation argues that…”
Example 4 — Computer Science (PhD thesis, Imperial) — opening
“Transformer-based language models trained on US clinical text achieve state-of-the-art performance on medication-extraction tasks (Alsentzer et al., 2019; Yang et al., 2022). Their performance on UK National Health Service records, however, has not been systematically evaluated. NHS records differ from US clinical text in vocabulary, abbreviation density and structural conventions in ways that the existing literature has not characterised. This thesis evaluates…”
8 introduction-chapter mistakes that lose marks
- Weak hook. Generic openings (“In today’s world…”) signal lack of focus and disengage examiners immediately.
- Problem too broad. “Marketing is changing” is not a research problem; “the gap between sustainability awareness and purchase intention in UK Gen Z” is.
- Research question buried. The RQ should be findable in 30 seconds of reading; if examiners can’t locate it quickly, the chapter is failing.
- No contribution claim. Vague statements about “adding to the literature” without specifying what’s added.
- Definitions in the wrong place. Defining “marketing” or “consumer” wastes word count; define only terms with specific operational meaning in your study.
- Missing thesis map. Examiners need to know the journey before starting it; a clear structural overview anchors expectations.
- Inconsistent terminology. If you define your dependent variable as “purchase intention” in the introduction, don’t shift to “buying intent” later. Use one term, define it, stay with it.
- Promise more than the dissertation delivers. If your introduction sets up a contribution your data can’t support, examiners will catch it in the discussion. Calibrate claims to evidence.
