Scored on evidence and ranked by a short script, twenty-two exposures in one composite orthopedic practice fall into three bands in HI575's Unit 4 matrix. Searches like "hi 575 unit 4 assignment example", "hi575 unit 4 sample" and "hi575 unit 4 example" land here.
What a finished HI575 Unit 4 risk analysis matrix looks like
The document runs five pages with an appendix. Two scale tables open the document: likelihood defined from 1, not expected within five years, to 5, expected more than once a year, and impact from 1, a handful of records with no care disruption, to 5, the whole patient base exposed or surgery canceled. The main table repeats each pair from the prior analysis with its likelihood, the evidence for that number, its impact, the evidence for that one, and the product. The imaging archive scores 4 for likelihood, citing the patch report and the open vendor connection, and 5 for impact, since the archive holds every image since 2014 and feeds the surgery center. A heat grid plots all twenty-two. The appendix prints the script, its input file and the three paper recalculations.
How a HI575 Unit 4 example is structured
Scales come before scores, and each level is defined in terms the practice can check, frequency over a period for likelihood, records affected and care disrupted for impact, so two readers would assign the same number. Every score then carries its basis in the next column; a number with no sentence behind it is treated as missing. The script handles only arithmetic and ordering: it reads the pairs from a small CSV file, multiplies, sorts descending and assigns bands at stated thresholds, 15 and above high, 8 to 14 moderate, below 8 low. The recalculated rows show the code does what the text claims. Interpretation follows the output rather than preceding it. Ties receive a paragraph, because two pairs sharing a score of 20 are separated by which one the practice can reduce sooner. A sensitivity note closes: which rows change band if one likelihood moves a level.
Scales defined in local terms
Likelihood by frequency over a stated period and impact by records exposed and care disrupted, each level written so two raters would pick the same number.
A basis beside every score
The patch report, last quarter's phishing reports and the archive's record volume cited cell by cell, so the ranking can be argued with rather than simply accepted.
Arithmetic left to code
A short Python script reads the pairs, multiplies, sorts and bands them at thresholds stated in the text, printed in full alongside its input file.
Three rows recomputed on paper
The archive, the departed therapist's account and the basement closet worked without the script and matched to its output, so the figures are verified rather than trusted.
Ties and near misses
Two pairs sharing a score of 20 separated by how soon each can be reduced, and the rows that cross a band if one likelihood rating moves a level.
Where marks go in HI575 Unit 4
Ratings with no stated basis undo the whole exercise, because high, medium and low become opinions the reader cannot test, and many sections award the basis column separate credit. Undefined scales come close behind; a 3 means nothing until the paper says what separates it from a 4. The script earns nothing on its own. Output never checked by hand, or thresholds chosen after the sort to make the ranking look tidy, reads as decoration. Multiplying ordinal scores is itself contestable, and stronger submissions say so in a sentence instead of presenting the product as a measurement. Impact written only as data exposed misses care disruption, which matters for a practice running a surgery center. Heat grids with no key cost small points. Ties decided silently, with no sensitivity check, suggest the ranking was never questioned.

The pairs your own analysis produced are what a custom matrix should score. Share them with the Unit 4 prompt and the rubric; the sample then defines the scales, cites a basis for each rating and ranks the results, by spreadsheet, hand or script as your section prefers. The first sample is free and ready within 24-48h.
HI575 Unit 4 questions, answered
Do I have to use a script to build the matrix?
No. Most sections accept a spreadsheet or a table worked by hand, and rubrics look at the reasoning rather than the tool. The example uses a short script because twenty-two rows invite arithmetic slips and the code makes the banding rule explicit. Whatever the method, state the thresholds and show at least a few rows recomputed independently.
Is multiplying likelihood by impact mathematically valid?
Not strictly, since both scales are ordinal rankings rather than measurements, and a 4 is not twice a 2. The practice is common in health care risk work because it produces a usable ordering. The example acknowledges the limitation in one sentence and uses the product only to sort and band, never to claim that one risk is a precise multiple of another.
How should impact be scored for a health care organization?
Beyond the number of records exposed, many sections expect care disruption and data integrity to count. The example's impact scale combines records affected with whether clinics or the surgery center would stop, so an archive outage scores high even if nothing leaves the building. A scale built on confidentiality alone tends to underrate ransomware and plain system failure.
