Narrowed from a nationwide transportation problem, a composite MT314 Unit 3 brief settles on hourly workers who lose jobs after car repair bills of [$300] to [$1,500]. Searches like "mt 314 unit 3 assignment example", "mt314 unit 3 sample" and "mt314 unit 3 example" land here.
What a finished MT314 Unit 3 problem definition brief looks like
Five pages moving from wide to narrow in four steps, with a funnel diagram on page one. The national step uses American Community Survey commuting data and the Federal Reserve's annual household survey, in which only about six in ten adults say they would cover an unexpected $400 expense with cash or its equivalent. The county step adds local facts: [58,000] residents, no fixed-route bus outside the county seat and a median commute of [24] miles. The employer step reports interviews with [six] human resources managers, [four] of whom named car trouble among the leading causes of attendance terminations. The final statement fits in one sentence. Exclusions get the last section, each with the reason it was made.
How a MT314 Unit 3 example is structured
Each narrowing step surrenders breadth deliberately. Transportation barriers include having no car, having no license and having a car that stops working, and the brief chooses the last because it is sudden, common among employed people and fixable at a known cost. Geography narrows next to one county, where one modest operation could know every major employer. The population narrows to hourly workers already in jobs, since keeping employment is more measurable than finding it. The cost band follows the interviews: below [$300] most workers manage, and above [$1,500] replacing the car becomes the question rather than repairing it. The final statement names who, where, what happens and at what threshold, with a measurable consequence, job loss within [30] days. Exclusions are stated plainly, license suspensions and childcare among them, making clear the problem was chosen, not stumbled into.
Wide to narrow in four steps
National barrier, one county, employed hourly workers, then a repair-cost band, each step drawn on a funnel with what it leaves behind.
Evidence at each width
Federal survey data at the top, county transit and commuting facts in the middle, and [six] employer interviews at the narrow end.
Why a breakdown, not no car
Sudden, common among people who already work and fixable at a known price, which makes it something a modest local operation could act on.
The one-sentence statement
Who, where, what happens and at what cost threshold, with job loss inside [30] days as the consequence any response would have to change.
Exclusions with reasons
Suspended licenses, childcare gaps and households with no vehicle at all, each set aside deliberately and flagged as a separate problem.
Where marks go in MT314 Unit 3
Problem statements the size of a country are the most frequent weakness in this unit, and graders read them as a sign the writer has not decided anything yet. Credit rises with each narrowing step justified by evidence, so the interviews and the cost band carry more weight here than the national statistics. A brief that leaps to a solution in its first paragraph is marked down, because the assignment wants the problem alone, and no repair shop appears anywhere in this example. Vague populations such as 'low-income families' cost marks for clarity because nobody could count them. Exclusions earn credit when their reasons are given, showing the narrowing was deliberate. A final statement with no measurable consequence leaves later units, outcomes and measurement, with nothing to build on.

Describe the broad problem your Unit 3 prompt starts from and the place in focus, and add the rubric. Inside 24-48h the brief is back, narrowed in stated steps, evidenced at each width, ending in a one-sentence problem statement with a measurable consequence. No payment is taken for an initial custom sample, which stays with the problem and leaves solutions for later units.
MT314 Unit 3 questions, answered
How narrow is too narrow?
When the problem affects too few people to sustain an organization or to show change. The example checks this by estimating how many workers fall inside its band each year, roughly [400] by the employers' own figures. If your narrowed problem shrinks below a workable number, the sample says so and widens one step instead of pretending the count is fine.
Should the brief mention my venture idea?
Generally not yet. Most MT314 problem briefs are graded on the problem alone, and a solution in paragraph one suggests the problem was chosen to fit it. The example never mentions a repair shop. If your prompt explicitly asks for a proposed direction, the sample adds it at the very end, clearly separated from the definition.
Where does local evidence come from without fieldwork?
Public data first: census commuting tables, transit maps, county economic reports and employer announcements. Interviews strengthen a brief when your course permits them, and the example shows how they would be reported. Without interviews, the sample relies on published local reporting and says what primary evidence would confirm the narrowed problem.
