Original educational scenarios. Every specimen, score and condition below is fictional. These are reproducible arithmetic examples, not test data or recommendations.
Case 1 / one preference changes
Would the same shortlist hold if the owner valued care-routine fit more strongly?
Both fictional candidates share the same exposure and installation preference scores. Candidate A has the appearance preference; candidate B has the care-routine preference. Change only care importance to see the tradeoff. Neither candidate has completed mandatory requirement review.
A change in preference order can be legitimate without any change in the product. Record whose priorities changed and why; do not describe the result as a new material-performance finding.

2. When a missing interface score matters
The first two candidates have overlapping preference possibilities when installation importance is high. Move that importance to zero and see the numeric uncertainty disappear. The missing requirement does not disappear: a preference weight cannot waive installation verification.
A narrower range can come from ignoring a preference, rather than obtaining evidence. Always inspect the requirement screen before interpreting a tidy result.
3. When the highest score must be excluded
Candidate A receives the highest fictional preference scores, but its exercise record says a mandatory condition is not met. Changing weights never removes that exclusion. Candidate B remains pending until its own requirement review is completed.
Preference scores help compare acceptable options; they cannot compensate for a documented mandatory conflict. Resolve or replace the candidate, then repeat the requirement review.
Surface study / fictional samples
Illustrative surface study. These are fictional samples, not identified products or measured performance evidence. Detail views crop the same master image.
One scene. Three surfaces.
Compare surface character under consistent illustrative light. Choose a sample to separate a visible observation from an evidence requirement.
What remains unknown
None of these appearances establishes product identity, mechanical suitability, service life or approval for your project.
The next useful question
Obtain actual labeled samples and exact product documents, then record the requirement and its source in your comparison.
How to identify products for a decking material comparison
Evidence lens 1
Record the precise product or wood description.
Select a focus to examine its role. These are review relationships, not a construction sequence or approval checklist.
Two candidates both say “composite.” One product record is incomplete until its exact line and installation document are supplied, so the worksheet keeps it unresolved.
Choosing decking materials around project priorities
Evidence lens 1
Screen intended use and installation conditions.
Select a focus to examine its role. These are review relationships, not a construction sequence or approval checklist.
A low-care preference initially dominates, but difficult access for future board replacement changes the discussion. Revise the brief rather than presenting the first score as objective truth.
Identify exact geometry and installation document.
Select a focus to examine its role. These are review relationships, not a construction sequence or approval checklist.
A diagonal design is proposed after the shortlist is made. Revisit each candidate’s installation limits before comparing material quantities or quotations.
Explore hypothetical decking shortlists where priorities change: comfort, appearance, maintenance and documented suitability. These are decision exercises, not product test results.
