Arranged from order to closed loop, [22] needs for referral tracking appear in the HS420 Unit 4 list, every one traced to a problem the clinic has already counted. Searches like "hs 420 unit 4 assignment example", "hs420 unit 4 sample" and "hs420 unit 4 example" land here.
What a finished HS420 Unit 4 requirements list looks like
Six headings follow a referral from birth to closure: ordered, sent, scheduled, seen, reported and closed. Under each sit numbered statements written as what the system shall do, followed by a because clause pointing at evidence. One example: the system shall flag any referral with no specialist report [30] days after its appointment date, because [57] referrals in one month stalled at exactly that point. Each statement names the user it serves and a priority of essential or desirable, and essential items are kept to those the clinic cannot work without. A shorter list of non-functional needs, response time, access by role and availability during clinic hours, follows the six headings. A final box lists things deliberately left out, such as booking specialist appointments from inside the clinic.
How a HS420 Unit 4 example is structured
A short introduction states the department, the problem from earlier analysis and who wrote the list, since requirements carry more weight when the users drafted them. Method follows in a paragraph: two working sessions with staff, each requirement checked against the referral map, and duplicates merged. The list itself is the body. After it, a traceability table maps every statement back to a step or a counted problem, which shows at a glance that nothing on the list is a wish from a brochure. Priorities are defended in a paragraph, explaining why only [9] of the [22] are essential and what the clinic would do by hand if a desirable item were missing. The deliberate exclusions close the document, with a sentence on why each stays out of scope.
Who wrote the list
The coordinator, two medical assistants and one provider named by role, with the working sessions that produced the statements described.
Ordered to closed
Six life-stage headings with numbered shall statements, each carrying a because clause that points at counted evidence.
Needs that are not features
Response time, access by role and availability in clinic hours, listed apart because no single screen satisfies them.
Traced back to the map
A table matching every statement to a process step or counted problem, so no requirement arrives without a reason.
Nine essential, thirteen desirable
The priority split defended, including what staff would do by hand if a desirable requirement went unmet.
Left out on purpose
In-clinic booking of specialist appointments and other attractive extras, each excluded with one sentence of reasoning.
Where marks go in HS420 Unit 4
Requirements written as product features are the frequent problem here: a list reading like a vendor's brochure shows that the products were examined before the needs. HS420 rubrics generally look for needs stated independently of any product and tied to the department's actual work. Vague statements lose ground as well; user-friendly and efficient cannot be checked against anything. A list where every item is essential suggests no prioritizing happened. Graders also notice missing users. A referral tool touches the coordinator, medical assistants, providers, specialist offices and patients, and a list written only for the coordinator has missed most of them. Non-functional needs are often forgotten entirely. Stronger lists include a short exclusions section, which shows scope was decided rather than drifted into.

HS420 Unit 4 questions, answered
How many requirements should the list contain?
Enough to cover the process without padding it. The example stops at twenty-two because the referral life cycle produced that many distinct needs once duplicates were merged. Some prompts set a minimum; where none is given, somewhere between fifteen and thirty often covers a single process. Every item should be traceable, so an extra requirement with no reason behind it weakens the list.
What does a because clause add?
It shows where the requirement came from. A statement that the system shall flag missing reports is reasonable; the same statement tied to [57] referrals that stalled at that point is persuasive and easy to prioritize. When vendors later claim to meet a requirement, the clause also reminds the evaluator what problem the feature has to solve.
Should the list include cost limits?
Budget is usually kept separate from requirements, since a need does not change because money is short. The example notes the clinic's budget ceiling in the introduction and leaves price for the selection unit. If a prompt asks for cost as a requirement, it can appear under non-functional needs, stated as a limit rather than a preference.
