What a finished DBA-955 Topic 8 proposal method defense brief looks like
The finished brief opens with the study on one page: a mixed design combining the airline's operational delay records for two stations with a survey of ramp supervisors and a small set of interviews. The rest is organized by question. Why these two airports, and what makes them comparable. How the candidate will obtain delay records through a research approval rather than through the system he uses every shift. Whether a survey of supervisors, some of whom report to him, can yield candid answers, and what the design does about it. Whether measuring predictors and outcomes on the same survey invites the common method bias Podsakoff and colleagues cataloged, and why delay outcomes come from records instead. Each answer is short and ends by pointing to the section of the proposal that carries it.
How a DBA-955 Topic 8 example is structured
The brief is built for rehearsal rather than for submission and runs in five parts. It begins with a one-page summary of the design, written so that every later answer can point back to it. The second part lists the method questions the candidate expects, ordered by how much damage each could do if answered badly rather than by chapter. A third part gives each question an answer of a few sentences, followed by the design feature that supports it and the proposal section where that feature appears. The fourth part collects the questions that expose genuine weaknesses, such as a comparison of only two stations, and prepares concessions that bound each weakness without abandoning the design. The last part lists questions about significance and contribution briefly, since a committee typically settles those only after the method holds.
The design on a single page
A one-page summary of stations, records, survey and interviews gives every later answer a fixed reference point, so replies under pressure stay consistent.
Questions ordered by potential damage
The brief ranks expected questions by how badly a weak answer would hurt the proposal, which puts comparability and access ahead of anything about significance.
Records obtained as a researcher
Delay data will come through a research approval from the operations data office, not through the dispatch system the candidate uses on shift.
Common method bias addressed by source
Taking delay outcomes from operational records rather than from the supervisor survey follows the remedy Podsakoff and colleagues describe for same-source measurement.
Concessions that bound a weakness
Two stations cannot represent a network, and the brief prepares an answer that admits this plainly and limits the claims to the comparison actually made.
Where marks go in DBA-955 Topic 8
Rehearsing the study's importance while leaving method questions to improvisation is the costliest mistake a defense brief makes, since it reverses where a committee actually spends its time. A second weakness is answering the insider question with reassurance, promising objectivity, rather than pointing to a design feature such as excluding direct reports or drawing outcomes from records. Briefs that anticipate only friendly questions leave the candidate unprepared for the one about comparability, usually the first to arrive when two sites are studied. Answers written as paragraphs of justification collapse under follow-up; answers tied to a named section of the proposal survive it. Some briefs treat every weakness as defensible and end up defending the indefensible, when a clean concession would have cost less. Citing methodologists without connecting their point to this design adds names and no protection.

DBA-955 Topic 8 questions, answered
What does a committee ask at a proposal defense?
Mostly questions about method: whether the design can answer the question, whether the sites or participants are comparable, how access will be obtained and how the researcher's position is handled. Questions about significance tend to come later and weigh less once the method holds. The example orders expected questions by how much a weak answer would cost, which usually puts comparability and access first.
What is common method bias?
Distortion that arises when predictors and outcomes are measured with the same method or from the same source, such as one survey completed by the same respondents. Podsakoff and colleagues reviewed its sources and remedies, one of which is taking measures from different sources. The example follows that remedy by drawing delay outcomes from operational records rather than from the supervisor survey.
Should I admit weaknesses at my defense?
Where they are real, yes, and bounded carefully. A committee will usually find a genuine weakness, and a prepared concession that limits the claim costs far less than a defense that collapses under follow-up. The example concedes that two stations cannot represent the network and restricts its conclusions accordingly. Your own defense, and every answer you give in it, remains your work.
