For a composite distributor study, GB730's Unit 4 design justification argues for explanatory sequential mixed methods by ruling out three considered alternatives on stated grounds. Searches like "gb 730 unit 4 assignment example", "gb730 unit 4 sample" and "gb730 unit 4 example" land here.
What a finished GB730 Unit 4 design justification looks like
Page one of six restates problem, purpose and questions in a boxed summary so the reader can hold the design against them. Pages two and three examine the alternatives in turn. The quasi-experiment fails on a fact of the setting: the software went live at all [14] branches in the same week, leaving no comparison group. The qualitative case study would explain decisions but could never tell sales leaders whether overrides relate to conversion. A survey would ask reps to report behavior the quote records already hold, and less accurately. Pages four and five present the chosen design with a procedural diagram: phase one quantitative, a connecting step that selects interviewees, phase two qualitative, then integration. Page six lists the design's own weaknesses without apology.
How a GB730 Unit 4 example is structured
Each alternative is judged against the same three tests, and the tests come from the problem rather than from a methods text: does the design answer both unknowns, what happens and why; can Merritt support it; does it use the strongest evidence available? The chosen design passes all three, but the justification goes further than a pass. It cites Creswell and Plano Clark for the explanatory sequential form and then argues the connecting step specifically, with interviewees chosen from phase one results, reps whose override behavior departs furthest from the pattern, so the qualitative strand explains what the numbers found rather than circling the topic. Weaknesses are stated plainly: time, since phase two waits on phase one, and the risk that phase one finds nothing worth explaining, which a planned alternative sampling rule answers.
Three tests drawn from the problem
Two unknowns, organizational feasibility and strength of evidence. Deriving the tests from the problem keeps the comparison from quietly favoring whichever design was preferred at the start.
A quasi-experiment with no comparison group
Simultaneous rollout removes the control group a branch comparison needs. The justification checks whether anything else could serve, such as a product line excluded from the software, and finds it far too small.
Why interviews alone would not do
A case study would illuminate reasoning but leave the executive's question unanswered. The problem statement named conversion and margin, and only transaction records can speak to those.
The connecting step
Phase one estimates each rep's override pattern, and phase two samples reps at the extremes. That choice is what makes the second phase explanatory rather than exploratory, and the justification defends it at length.
Weaknesses the design keeps
A longer timeline, dependence on phase one findings and the candidate's place inside Merritt's pricing team. Each is named, along with the mitigation later units will develop.
Where marks go in GB730 Unit 4
Justifications in GB730 lose force when the alternatives are straw men. A rival design dismissed in one sentence, quantitative research cannot capture meaning, signals that the choice came first and the defense afterward, the defect the course most wants to catch. Each alternative deserves its strongest case and a rejection grounded in the specific study. Citing the design's source correctly matters, and explanatory sequential is often confused with exploratory sequential. The connecting step between phases deserves its own argument, since that is where many mixed designs quietly become two separate studies. Feasibility claims need facts from the setting, not assumptions about it. A section admitting the chosen design's weaknesses reads as confidence rather than doubt, and graders tend to credit it.

GB730 Unit 4 questions, answered
Is a mixed methods design harder to defend in GB730?
It requires more argument, because a reader will ask what the combination achieves that either strand alone could not. The answer must be specific: in an explanatory sequential design, the qualitative phase explains patterns the quantitative phase found. If the justification cannot say what integration adds, a single-method design is often the stronger choice.
How many alternatives should the justification consider?
Two or three serious ones is common. Include at least one from a different paradigm, so the choice between qualitative, quantitative and mixed is argued rather than assumed. An alternative that could plausibly have been chosen makes a stronger comparison than a design nobody would ever propose for the problem. Each should be rejected for a reason tied to your own setting.
Can feasibility decide the design?
It can decide between designs that would each answer the question, but it should not be the only reason. Saying a design was chosen because it was easy reads poorly. Saying the stronger design was impossible because the setting lacks a comparison group, and showing that fact, is legitimate reasoning a committee will accept.
