How to Plan a Dissertation
Almost every dissertation that runs into trouble does so for the same reason: the plan allocated time to the parts the student could picture, and almost none to the parts they could not. Writing is easy to imagine and therefore easy to schedule. Waiting six weeks for an ethics committee is not.
This guide gives a working timeline built backwards from a submission date, with the stages that actually consume time costed honestly. It assumes a taught dissertation of 10,000 to 18,000 words. Scale the durations rather than the sequence if yours is longer.
| Plan direction | Backwards from the deadline, never forwards |
|---|---|
| Ethics approval | Four to six weeks, plus revisions |
| Recruitment yield | Assume half your target |
| Write the introduction | Second to last, not first |
| Supervisor availability | Drops sharply over the summer |
| Biggest single risk | A question that is still too broad at week four |
Why you plan backwards
A forwards plan starts with what you will do next week and runs out of time somewhere near the end. A backwards plan starts with the deadline and works out what must be finished by when for that deadline to hold. The second one surfaces the impossible commitments early, while you can still change them.
Start with your submission date. Subtract two weeks for proofreading and final formatting. Subtract another two for supervisor feedback and revision, assuming you get one round. What remains is your actual writing and research window, and it is almost always shorter than students expect.
A working timeline, backwards from submission
This assumes a September submission for a taught master’s dissertation. Shift the months for an undergraduate spring deadline; the sequence and the durations hold.
| Weeks before deadline | Stage | Why this long |
|---|---|---|
| 26 to 24 | Narrow the question, confirm supervisor | Everything downstream depends on the question being answerable |
| 24 to 20 | Proposal drafted and approved | Approval is a gate, not a formality |
| 20 to 14 | Ethics submitted and approved | Four to six weeks is normal, revisions are common |
| 20 to 12 | Literature review drafted | Runs in parallel with waiting for ethics |
| 14 to 8 | Data collection | Start the day approval lands; over-recruit early |
| 8 to 6 | Analysis and results chapter | While the detail is fresh |
| 6 to 4 | Discussion chapter | Carries the critical-thinking marks; do not compress it |
| 4 to 3 | Conclusion, then introduction, then abstract | In that order, because they summarise finished work |
| 3 to 1 | Supervisor feedback and revision | Book the slot in advance |
| 1 to 0 | Proofreading and formatting | Book externally ahead of the deadline, not on it |
The three stages that break timelines
Ethics approval is the first and the least controllable. Committees meet on a schedule, revisions are routine rather than exceptional, and nothing involving participants can begin until it clears. Submit earlier than feels necessary, and while you wait, draft the literature review.
Recruitment is the second. Response rates to student surveys are consistently around half what students assume when planning, and interview no-shows are common. The fix is to over-recruit at the start rather than extend the window at the end, because extending eats the analysis time you cannot compress.
Supervisor availability is the third. Taught dissertations are submitted in the period when academic staff have least availability, and chasing in August rarely works. Agree specific feedback dates in writing during term time, and treat them as fixed appointments rather than intentions.
The order to write in
Dissertations are read from introduction to conclusion and are almost never written that way. Trying to write in reading order is a reliable way to stall at chapter one, because you cannot preview a document that does not exist.
- 1Methodology first. It has to be approved before you collect anything, and drafting it exposes whether your design actually answers your question.
- 2Literature review second, in parallel with data collection. It evolves as you read, so drafting early and revising late is more efficient than one perfect pass.
- 3Results third, as soon as analysis is done.
- 4Discussion fourth. Most of the critical-thinking marks sit here, so give it real time.
- 5Conclusion fifth, once you know what you actually found.
- 6Introduction sixth. Now you can preview the dissertation accurately.
- 7Abstract last. It summarises a finished document.
Running the plan week to week
A timeline you never look at is a document, not a plan. Three habits make the difference between a schedule that holds and one that quietly slips.
- Set a weekly word target rather than a daily one. Daily targets break on the first bad day and then get abandoned entirely.
- Track what is finished, not what is started. A half-drafted chapter is zero for planning purposes because you cannot estimate the remainder reliably.
- Review the plan every fortnight and move things explicitly when they slip. Silent slippage is what turns a two-week overrun into a crisis in month five.
- Keep a running list of decisions and why you made them. Your methodology chapter and your viva both need it, and reconstructing it later is much harder.
Tools worth setting up before week one
None of these are essential and all of them save more time than they cost. The common factor is that they remove decisions you would otherwise make repeatedly under pressure.
- A reference manager, Zotero or Mendeley, configured to your university Harvard variant rather than the generic default. Retrofitting 80 references at the end is a full day you will not have.
- A single working document with heading styles applied from the start, so the contents page generates itself and page numbering does not break in week fifteen.
- A decisions log: one line each time you change scope, method or sample, with the date and the reason. Your methodology chapter and your viva both need this, and reconstructing it from memory is unreliable.
- A backup that is not your laptop. Cloud sync plus one other copy. Data loss in month four is recoverable only if you planned for it in month one.
- A reading note template with three fields: what the source claims, what evidence supports it, and what it means for your gap. Notes without the third field produce a literature review organised by source.
Working with your supervisor
Supervision is a finite resource and most students under-use it early then over-request it late, which is exactly the wrong way round. Your supervisor is most useful when the decisions are still reversible.
Come to meetings with specific questions rather than general progress. "Is my sampling strategy defensible given I cannot access the population I originally proposed?" produces a useful answer. "How am I doing?" produces reassurance you cannot act on. Send material at least three working days ahead, and send the specific chapter rather than the whole draft.
Write up every meeting in three lines: what was decided, what you agreed to do, and by when. Email it to your supervisor. This takes two minutes, prevents the most common source of disagreement later, and gives you a record if a dispute about supervision ever arises.
Frequently asked questions
How long does a dissertation take?
Plan for three to six months alongside other work for a taught dissertation. The writing itself is rarely the constraint. Ethics approval, recruitment and data collection consume more time than students expect, and they are the stages with the least flexibility.
When should I start writing?
Immediately, starting with the methodology. Waiting until research is finished before writing anything is the most common planning error, because it front-loads all the writing into the period with the least slack.
How long does ethics approval take?
Four to six weeks at most UK institutions, and longer if revisions are requested, which is routine rather than exceptional. Committees meet on a fixed schedule, so missing a meeting date can add a month.
What if I fall behind schedule?
Re-plan explicitly rather than working harder against a timeline that no longer holds. Identify what can be cut: sample size, scope of the literature review, or the ambition of the analysis. Cutting scope early is far better than running out of time in the discussion chapter.
Should I plan word counts by chapter?
Yes, as percentages rather than fixed numbers. Roughly 10% introduction, 30% literature review, 15% methodology, 20% results, 20% discussion and 5% conclusion. Adjust for your discipline, but knowing the target stops one chapter consuming the whole budget.
