Learning outcomes
You will (1) structure a dissertation around a claim; (2) write limitations that inform decisions; (3) report privacy safeguards used in the research.
7.1 Structure around a claim
Hana organises the dissertation around one claim: the portal is associated with higher on-time completion within both simple and complex access requests, without loss of completeness or safety. Each chapter supports part of that claim. The literature review explains why on-time access matters, the method explains the design and rivals, the results report the stratified figures, and the discussion weighs the remaining rival. Dr. Pritchard asks her to remove a section on cookie banners that she found interesting but that does not support the claim, and she agrees after moving the notes to a future-work appendix.
7.2 Limitations that matter
Hana writes limitations as information for decision-makers rather than apologies. One company limits generalisation to similar retailers; the website redesign remains an unseparated rival; the completeness sample of forty answers per period can detect only large changes; and the legal analysis follows the GDPR and LGPD texts and EDPB guidance, not court decisions. For each limitation she states its likely direction: for instance, the redesign probably inflates the effect slightly. This tells Brookfield's managers how to adjust their expectations rather than leaving them to guess how serious each weakness is.
7.3 Reporting safeguards
A dissertation about privacy must show it respected privacy. Hana's methods chapter describes the metadata-only extract, the analysis inside Brookfield, the merging of small categories and the ban on linking tickets to customers. She also reports one incident: an early extract contained a free-text notes column, which she noticed and returned unopened. Reporting the incident shows the safeguards worked and gives other students an example of what to watch for. Brookfield's data protection officer reviews the chapter before submission and confirms that it reveals nothing about individual customers.
7.4 Writing for two audiences
Hana writes the dissertation for examiners and a two-page summary for Brookfield. The summary leads with the decision: retire the email route for access requests and keep monitoring completeness and misdirected disclosures. It states the result in plain numbers, names the remaining rival and recommends a follow-up after the redesign settles. She avoids terms such as bootstrap in the summary, replacing them with "a range that the true improvement very probably lies in". Dr. Pritchard notes that a good summary lets a manager act correctly even if they never read the dissertation itself.
Worked example
Hana builds the dissertation around one claim, writes limitations with their likely direction, reports a caught free-text incident and produces a two-page decision summary.
Synthetic case. The incident and summary are synthetic; GDPR, LGPD and EDPB Guidelines 01/2022 are real.
Errors and limits
A short summary can lose nuance; it should point to the full limitations.
Exercises
- EX039 — Cut section. Why did Hana remove the cookie-banner section? Rubric: 3 = it did not support the central claim;; 2 = mentions focus;; 1 = keeps it;; 0 = none.
- EX040 — Direction of bias. Why state the likely direction of each limitation? Rubric: 3 = so decision-makers know how to adjust expectations;; 2 = mentions usefulness;; 1 = lists limits only;; 0 = none.
- EX041 — Free-text incident. What should Hana do when an extract contains free-text notes? Rubric: 3 = return it unopened and report the incident;; 2 = returns it;; 1 = reads it;; 0 = none.
- EX042 — Legal scope limit. What is the limit of Hana's legal analysis? Rubric: 3 = it uses statutes and EDPB guidance, not case law;; 2 = mentions sources;; 1 = omits;; 0 = none.
- EX043 — Plain language. How does the summary describe the bootstrap interval? Rubric: 3 = as a range the true improvement very probably lies in;; 2 = similar phrase;; 1 = uses jargon;; 0 = none.
- EX044 — DPO review. Why does the data protection officer review the methods chapter? Rubric: 3 = to confirm it reveals nothing about individual customers;; 2 = mentions privacy;; 1 = omits;; 0 = none.
Synthesis
Chapter 7 writes a bounded dissertation and a decision summary. Chapter 8 faces independent review and the defense.
