Nine criteria given weights while every candidate was still unnamed, three approaches scored and a leader tested under 1,000 reweightings: the HI580 Unit 4 matrix for one labor unit. Searches like "hi 580 unit 4 assignment example", "hi580 unit 4 sample" and "hi580 unit 4 example" land here.
What a finished HI580 Unit 4 system selection matrix looks like
Six pages and a code appendix. A criteria table comes first, nine rows drawn from the requirement groups: surveillance and archive, bedside documentation, newborn linking, interface burden, downtime behavior, retrieval for risk management, training load, five-year cost band and vendor support. Beside each criterion sit the six raters' point allocations and the averaged weight; newborn linking and downtime behavior carry the most. The three candidates appear only after that table: the record vendor's obstetric module with built-in surveillance, a standalone surveillance system connected by interface, and an upgrade of the existing central station with new flowsheet mapping. Each receives a 0 to 5 score per criterion with its evidence source noted. The module leads by a narrow margin. A histogram shows it winning in [74] percent of the perturbed runs, the standalone system in the rest.
How a HI580 Unit 4 example is structured
The order is the argument. Criteria and weights are fixed and dated before candidates enter, so no reader can suspect the weights were tuned to a favorite, and the paper says the raters had not yet seen demonstrations. The point-allocation method is explained in a paragraph, including why forcing a total of 100 makes raters trade one criterion against another. Scores then follow with a stated scale and the source of evidence for each cell. The script does three jobs only: average the allocations, compute weighted totals, and shift every weight by up to 20 percent in each of 1,000 runs, counting winners. Two totals are recomputed by hand as a check on the code. Interpretation comes last and stays modest: a leader that loses a quarter of perturbed runs is a recommendation with a stated risk, and the paper names which criterion flips it.
Nine criteria from the requirements
Requirement groups turned into scoring criteria, each traceable to lines in the earlier list, so the matrix measures what stakeholders actually asked for.
One hundred points per rater
Six stakeholders allocating a fixed total across the criteria before any demonstration, with the averaged weights and the spread between raters both shown.
Three approaches, scored with sources
The record vendor's module, a standalone surveillance system and an upgraded central station, each scored 0 to 5 per criterion with its evidence noted.
A thousand reweightings
Every weight moved at random within 20 percent across 1,000 runs, and the share of runs each candidate wins, plotted as a simple histogram.
What flips the result
The single criterion whose weight, raised far enough, hands the lead to the standalone system, named so decision makers can see the real trade.
Where marks go in HI580 Unit 4
Weights assigned after candidates were known cost the most credibility, because the method can no longer be separated from the preference it produced; many sections check the order explicitly. A matrix built on features rather than requirements is the next frequent problem, scoring whatever the vendors happen to advertise. Scores with no scale definition or evidence source read as impressions. The script earns nothing unless its output is checked, and code that silently mishandles a missing score poisons every total. Narrow margins reported as decisive draw comments, which is why perturbation or another sensitivity test is valued. Leaving the upgrade option out narrows the comparison artificially. Raters drawn from a single discipline, all nurses or all IT staff, produce weights the rest of the unit will not accept, and graders notice who was absent.

HI580 Unit 4 questions, answered
Must the weights come from several stakeholders?
Not always, but a single author's weights invite the question of whose priorities they reflect. The example averages six raters and shows the spread between them, which reveals where roles disagree. If your scenario supplies no stakeholders, state the basis for each weight explicitly and consider testing how much the result depends on it.
What does perturbing the weights show?
Whether the winner depends on precise weights nobody could defend to a decimal point. The example nudges every weight at random within 20 percent across 1,000 runs and counts how often each candidate finishes first. A leader that wins nearly always is robust; one that wins three runs in four is a recommendation that carries a stated risk.
Should candidates be real products?
Many sections accept approaches described by type, as the example does with a vendor module, a standalone system and an upgrade. Where real products are required, cite published material with dates and avoid claims you cannot support. Either way, the scores should rest on evidence a reader can trace rather than on a vendor's reputation.
