Where GB890 reaches Unit 8, the purpose statement exercise tests three drafts against the Wexford problem and keeps the one whose every element the problem demands. Searches like "gb 890 unit 8 assignment example", "gb890 unit 8 sample" and "gb890 unit 8 example" land here.
What a finished GB890 Unit 8 purpose statement exercise looks like
Three parts across four pages. Part one reprints the problem statement as it stood after Unit 7, with key phrases numbered. Part two sets out three purpose drafts, each followed by a short diagnosis. Draft one, to reduce recordable injuries across Wexford's plants, fails because injuries are too rare to detect in a single season and the problem never claimed the project would lower them. Draft two, to improve safety culture, names a construct the framework never defined. Draft three reads: the purpose of this quasi-experimental project is to examine whether weekly feedback to shift supervisors on their safety conversations changes group safety climate and near-miss reporting in crews at two Wexford plants, compared with crews at two matched plants, over twelve weeks. Part three is an alignment grid.
How a GB890 Unit 8 example is structured
The exercise demonstrates a test rather than asserting a result. Numbering the problem's phrases first gives the reader a fixed reference, so each purpose element can be traced to a number or flagged as orphaned. Failed drafts appear because the unit is about alignment, and a successful sentence alone would hide the reasoning that produced it. Each diagnosis names the specific break: a promised outcome the problem did not justify, or a term missing from the framework. Draft three is then checked in the grid element by element, design, intervention, population, outcomes, setting, comparison and duration, each tied to a problem phrase or a framework construct. Two cells note tensions left for the design course: whether twelve weeks is long enough for climate to shift, and whether two matched plants can stand in for random assignment.
Phrases numbered first
The problem statement reappears with its key phrases numbered one through seven. Every later judgment about alignment refers to those numbers rather than to a general impression of fit.
Reduce injuries, rejected
Recordable cases occur about once a month per plant, too rarely for a twelve-week comparison. The problem also never claimed the project would lower them, so the draft promised an outcome nothing above it required.
Safety culture, rejected
Culture appears nowhere in the Unit 7 framework, which defines climate at crew level. A purpose naming an undefined construct cannot be measured or aligned, and the diagnosis says so in one sentence.
The draft that holds
Quasi-experimental design, weekly supervisor feedback, crews at two plants against two matched plants, climate and near-miss reporting as outcomes, twelve weeks. Each element traces back to a numbered phrase or a named construct.
Tensions left open
Two grid cells carry questions rather than ticks: whether climate moves in twelve weeks, and whether matched plants substitute adequately for random assignment. The exercise leaves both for the design course.
Where marks go in GB890 Unit 8
A purpose that could have been written without reading the problem is the defect GB890 instructors look for first here, and they find it by checking each element of the purpose against the problem above. Outcomes the problem never mentioned, or constructs the framework never defined, show the chain has broken. Purposes naming several designs, or none, get sent back, as do statements hedged so broadly that no result could fail them. Exercises showing rejected drafts with specific diagnoses earn credit, since the reasoning is what the unit examines. An alignment grid turns fit into something checkable. Honesty about remaining tensions, such as study length or the quality of a comparison, usually counts for more than a purpose presented as flawless, because those tensions will surface at proposal regardless.

GB890 Unit 8 questions, answered
What elements does a DBA purpose statement contain?
Commonly the design, the intervention or phenomenon, the population, the variables or outcomes, the setting and the time frame, in one or two sentences. Many programs publish a preferred wording pattern, and the one your section uses fixes the exact order. More important than any pattern is that each element traces back to something the problem statement established.
Why include failed drafts in the exercise?
Because the unit examines alignment, and a finished sentence alone hides the reasoning. Showing a draft that promised an unjustified outcome, with the specific reason it failed, demonstrates the test being applied. Instructors in this course often weigh the diagnoses as heavily as the final purpose, so they deserve real space on the page.
Should the purpose promise to solve the problem?
Usually not. A doctoral purpose examines, tests or describes; it rarely promises that a practice will fix the organization, since that presupposes the result. The Wexford draft examines whether feedback changes climate and reporting, leaving room for the answer to be no. A purpose that could only succeed tends to draw committee questions.
