How to Write a Dissertation Introduction: Structure, Example and Common Mistakes

I have my topic and a rough plan. What does my introduction actually need to say? Which parts come first? How long should it be? Should I write it now or after the rest of the dissertation? And how do I stop it turning into a second literature review?

Here is the short answer. To write a dissertation introduction, set out the context, narrow to your focus, show what is missing or unresolved, state your aim and research questions, define the scope, explain why the work matters, and close with a brief map of the chapters. Universities phrase this differently, but they ask for the same three things: what you are studying, why it matters, and how you will go about it.

What a dissertation introduction has to do

Your introduction is the first chapter your marker reads, and it sets the terms for everything after it. Edge Hill University’s guidance sums it up as a short overview of the what, the why and the how. What is the specific focus or question? Why does it take this shape, and why is it worth doing? How will you study it, and how is the dissertation organised?

Think of it as a promise. Whatever the introduction commits to, the rest of the dissertation has to deliver. That is why markers read it alongside your conclusion, and why the two should mirror each other.

The balance matters. Grad Coach advises writing on a need-to-know basis, because you are so close to your topic that small details start to feel essential. Save the depth for later chapters.

Dissertation introduction structure: what to include, in order

There is no single template, and your department’s handbook always wins. Still, the guidance from Scribbr, Grad Coach, Sunderland, Sheffield Hallam and Edge Hill converges on the sequence below. Humanities dissertations that build an argument by theme may reorder it, so check your own brief.

1. A short opening that names the field and the problem

Grad Coach suggests four foundation sentences: one introducing your overall field, one introducing your specific problem, one stating your aim, and one outlining the chapter. Together they fit in a paragraph or two. Avoid a dry “This dissertation will explore…” opening if you can. A concrete debate, development or practical problem draws the reader in faster.

2. Background and context

Give the reader enough to understand your topic, and no more. Explain any jargon, because your marker cannot ask you what a term means. Scribbr advises showing why the topic is timely or important, for example through a live debate or a practical problem. Cite the key sources, but leave the detailed critique for the chapter that follows.

3. The research problem or gap

This is where you show why the study is needed. Grad Coach breaks it into three moves: what is already well established, what is missing or contested, and why that gap is a problem. Sunderland’s overview table follows a similar line, running from the wider context to your specific area, then the gap, then your aim or questions.

Your gap does not need to be dramatic. It can be an unexplained difference, a disagreement in the literature, or a setting nobody has studied closely. Just make sure it comes from reading, not assumption.

4. Research aim, objectives and questions

Scribbr calls this perhaps the most important part of the introduction, because it sets expectations for every later chapter. Sheffield Hallam recommends one overarching aim, supported by usually three to five objectives. Objectives and questions say the same thing in different forms, so choose the format your department prefers. Action verbs such as investigate, assess or analyse make the project sound achievable.

Sunderland, drawing on Robson and McCartan, shows how wording signals purpose. An explanatory study asks whether something causes an effect, an exploratory one asks about experiences, and a descriptive one asks to what extent something occurs. If you are stuck on phrasing, a aims and objectives generator can give you a starting draft, and our guide to writing a research question that can actually be answered explains how to tighten it.

If your study tests hypotheses drawn from the literature, Scribbr notes that the introduction is a sensible place to state them. Edge Hill also allows for a principal argument or hypothesis here.

5. Scope and delimitations

State what you will cover and what you will not. Grad Coach suggests drawing boundaries by industry, country, time period or population. A tight scope keeps the project doable, and it is much easier to set once you have worked on narrowing a broad topic into something you can finish.

6. Significance

Say who benefits and how. Scribbr describes two routes: practical value, such as helping policy or management, and scholarly value, such as extending theory or adding evidence. Many projects offer both. Keep this section confident but proportionate, and avoid claiming more than a single dissertation can deliver.

7. Limitations

Not every department asks for limitations in the introduction, but Grad Coach includes them, and flagging them early shows you understand research design. It lists four common sources: scope, methodology, resources and how far findings generalise. Sheffield Hallam also mentions acknowledging limitations in the existing literature that shaped your topic. Keep the introduction version brief and develop it later.

8. A short chapter outline

Finish by guiding the reader through the document. Scribbr says one or two sentences per chapter is usually enough, with a short paragraph each if your structure is unconventional. Explain what each chapter contributes to your aim instead of just naming it. “Chapter 2 is the literature review” tells the reader little, while a sentence on what that review sets up tells them a lot.

Should I write my dissertation introduction first or last?

Both, in a sense. Scribbr suggests drafting a rough version early to guide your research, and the library guidance at Falmouth recommends a working introduction that you revisit once the full draft exists. SkillsYouNeed advises finalising it only after the rest is complete, since your argument often shifts as you write. Scribbr’s template idea is useful here: if you wrote a research proposal, reuse its structure as your first draft, then revise it so it matches what the dissertation really does.

Our guide to the dissertation proposal shows how much of that early draft you can carry over. Falmouth’s own drafting guide for dissertations sets out the working-introduction method step by step.

How long should a dissertation introduction be?

There is no universal figure, and your handbook overrides any rule of thumb. Several student guides quote roughly five to ten per cent of the total word count. A 10,000-word dissertation would then have an introduction of around 500 to 1,000 words. Treat that as a starting estimate, not a requirement. A 5,000-word piece, for example, may need more than 10 per cent simply to fit all the elements in.

Plan the budget early. A word count calculator splits your total across chapters, and a timeline planner helps you leave time to revise the introduction at the end.

Dissertation introduction example (illustrative)

The example below is invented to show the moves in action. The citations are placeholders, so replace them with real sources you have read.

Topic: hybrid working and line managers in UK local government.

Context. Many UK councils now operate hybrid models in which staff split their week between the office and home (Author, Year). Line managers sit at the centre of this change, because they are the ones who must coordinate teams that are rarely all present at once.

Problem. Research on hybrid working has focused mainly on employee wellbeing and productivity (Author, Year). Far less has examined how managers in public services adapt their supervision practices, so little is known about what helps or hinders them (Author, Year).

Aim. This study aims to explore how line managers in two English county councils adapt their supervision practices under hybrid working.

Objectives. (1) To identify the supervision practices managers have changed. (2) To examine the reasons managers give for those changes. (3) To assess which organisational supports managers find useful.

Scope and outline. The study covers two councils and managers of teams of five or more. Chapter 2 reviews the literature on supervision and flexible work, Chapter 3 justifies a qualitative interview design, and Chapters 4 and 5 present and discuss the findings before the conclusion returns to the aim.

Notice how each objective could be answered by a later chapter, and how the scope sentence already limits the claims the study can make.

Dissertation introduction vs literature review

Students often blur these two chapters. The introduction explains the topic and the case for studying it, citing only the sources needed to do so. The literature review then examines the evidence critically, comparing authors, methods and findings. One graduate writing coach puts it neatly: the introduction is about the topic, while the review is about people writing about the topic.

If you find yourself comparing studies in detail in Chapter 1, move that material to your literature review chapter. Likewise, keep method detail brief and leave it for the methodology chapter, as Scribbr advises.

Common dissertation introduction mistakes to avoid

• Too little background. Grad Coach and Vappingo both flag missing context as a frequent problem. Assume your marker is not a specialist in your niche.
• Vague aims and questions. If the reader cannot tell exactly what you will investigate, every later chapter suffers.
• An undefined scope. Without clear boundaries on where, when and who, the project risks becoming too big to finish.
• A review disguised as an introduction. Heavy citation and critique belong in the literature review.
• Promises the dissertation does not keep. Vappingo notes that an introduction commits to a question or argument, and trouble appears when later chapters drift away from it. Reread the introduction after drafting every chapter.
• Never revisiting it. An introduction written at the start and left untouched rarely matches the finished work.

Dissertation introduction checklist

• The opening names the field and the specific problem in plain language.
• Background explains key terms without becoming a literature review.
• The gap or problem is stated and linked to reading.
• One clear aim, with objectives or questions that each map to a later chapter.
• Scope states what is in and out, and limitations are acknowledged briefly.
• Significance names who benefits and how.
• The chapter outline says what each chapter does for the aim.
• It matches the finished findings and the dissertation conclusion.

Does the introduction change by subject or level?

The core components stay broadly similar from Bachelor’s to PhD, according to Grad Coach. What changes is depth, length and convention. Humanities dissertations often build a thematic argument, so the outline needs more explanation. Case study and extended literature review projects, which Sheffield Hallam covers separately, may skip a traditional methods-results split. Always read your marking criteria and any department template before settling on a structure.

Quick answers to common questions

Can I mention my findings in the introduction?

It depends on your department. City St George’s student guidance says you may outline expected answers, for example through a hypothesis or main argument. Some institutions want a brief preview of results. Check your handbook before deciding.

Do I need subheadings inside the introduction?

Practice varies. Oxbridge Essays advises sub-sections with headings, while other guides treat the introduction as continuous prose. Follow your department’s template if there is one.

How many objectives should I have?

Sheffield Hallam suggests usually three to five, each specific enough to answer. Fewer, sharper objectives beat a long list.
