Another team's kiosk specification examined line by line: each ambiguity quoted, its two readings shown, the cost of each estimated, and a rewrite offered, alongside a usability pass using Nielsen's heuristics.

What a finished MBAX 6640 Week 9 design critique looks like
A findings table dominates four to six pages. Each row quotes a line from the other team's specification exactly, then gives reading A and reading B as a developer and a user might take them, the likely cost of building the wrong one, a severity rating, and suggested wording. One row quotes a requirement that the kiosk should confirm check-in quickly and shows that it could mean a sound, an on-screen message, or a printed slip. Another quotes an undefined term, active volunteer. A second section applies Jakob Nielsen's ten usability heuristics to the kiosk design, flagging visibility of system status after a tap and error prevention for similar names. A brief summary ranks the findings and acknowledges what the specification does well.
How a MBAX 6640 Week 9 example is structured
The critique opens by stating its method: every requirement and screen description was read twice, once as a developer and once as a front-desk volunteer, and each line where the two readings diverged became a finding. Findings then follow the critiqued specification's own sequence, so its authors can find each one. Each is handled identically: the quoted line, both readings, the cost of each misbuild, a severity, a proposed rewrite. Usability comes next as a separate pass, organized by Nielsen's heuristics and limited to those the design actually engages. Severity ranking follows, putting ambiguities that would produce a wrong build ahead of those that would only produce a slow one. The critique closes by noting what the specification already does well, which tells its authors what to keep while revising.
Two readings per line
Each requirement was read once as the developer would and once as the front-desk volunteer would. Wherever those readings split, the line became a finding with both versions written out.
Quoted, not paraphrased
Every finding reproduces the exact wording under critique. Paraphrasing would substitute the critic's reading for the text, which is the very error the critique is trying to catch.
What each misbuild costs
A kiosk that prints a slip nobody wanted wastes paper; one that records arrival without a visible confirmation sends volunteers back to the desk. Each finding estimates the cost of the wrong build in plain terms.
Heuristics where they apply
Visibility of system status, error prevention and recognition rather than recall are applied to the check-in flow. Heuristics the design never engages are left out rather than filled in for completeness.
Severity, then strengths
Findings are ranked by whether they would lead to a wrong build or a slow one. What the other team's specification already does well gets its own closing paragraph.
Where marks go in MBAX 6640 Week 9
Graders want real ambiguities, found in the text and priced. A critique listing general weaknesses, such as the specification needing more detail, has not read the document closely and lands low. Credit rises with each quoted line whose two readings are shown to be genuinely plausible, since manufactured ambiguity is easy to spot. The cost estimate carries a sizable share because it answers the question every reviewer eventually faces: so what. Rewrites are assessed for whether they actually allow only one reading. Nielsen's heuristics earn credit when applied to specific screens and interactions; reciting all ten with a sentence each is marked as summary. Tone matters too, and acknowledging strengths reads as professional review rather than fault-finding.

MBAX 6640 Week 9 questions, answered
What counts as a genuine ambiguity?
A line that two competent readers could build or test in different ways, each consistent with the text. Vague words, undefined terms, missing conditions and unclear scope are common sources. If you can write both readings in a sentence each and neither contradicts the specification, the ambiguity is genuine. If one reading requires ignoring part of the text, it is not.
Which of Nielsen's heuristics should the critique use?
Those the design actually engages. For a check-in kiosk, visibility of system status, error prevention, recognition rather than recall, and help users recover from errors are usually relevant. Apply each to a specific screen or interaction and describe the problem it reveals. Listing all ten heuristics with a sentence each reads as a summary rather than a critique.
Should the critique rewrite the whole specification?
No. Offer a rewrite for each finding, limited to the line in question, so the authors can accept or adapt it. A full rewrite shifts the assignment from critique to authorship and usually buries the findings. Your value to the other team lies in pinpointing ambiguities and showing a precise alternative for each.
