- • This week you have built a stakeholder map, a patient-flow diagram, and a team contract.
- • Today you bring those tools together into an ER inefficiency brief -- the document that frames your design problem.
- • A brief is only as good as the evidence behind it, so every claim you make must trace back to something you observed or read.
- • This is also your first weekly summative: the quality of your brief sets the standard for the rest of Problem 1.
- • How to transform a bottleneck observation into a one-sentence design problem statement.
- • How to use your stakeholder map as evidence when describing who is harmed by the inefficiency.
- • What makes a design problem brief specific enough to guide solution development.

The deck carries the prior idea forward, lets you inspect an analogy, maps the rule to biology, and ends with the same evidence decision and exit ticket used on this page.
Generated from this lesson's canonical data with a red-team citation check.
A bottleneck caps the flow of the whole system, so locating it is the first step to a fix, because adding effort anywhere else leaves patients stacked in front of the same slow gate.
A design problem must be specific, observable, and tied to real harm so that it can guide a real solution, because a vague problem gives the designer nothing measurable to build or test against.
A smoke alarm detects signs of fire but can also react to burnt toast.
- What does the alarm detect?
- What creates a false alarm?
- What evidence is needed before declaring a fire?
A screening signal changes what to investigate next; it does not automatically prove the cause.
Biomedical tests have measured performance and biological sampling limits that a household alarm does not capture.
- • Alarm signal maps to a test result.
- • Burnt toast maps to a .
- • Inspection maps to confirmation or the next test.
Driving question: You found the bottleneck and mapped who it hurts. Now write the one sentence that names your ER inefficiency so precisely that a stranger reading it knows exactly what to fix and who is being harmed by not fixing it.
What you already know: A bottleneck caps the flow of the whole system, so locating it is the first step to a fix, because adding effort anywhere else leaves patients stacked in front of the same slow gate.
New idea: A design problem must be specific, observable, and tied to real harm so that it can guide a real solution, because a vague problem gives the designer nothing measurable to build or test against.
Visual or model: F1. F1. A lesson illustration or teaching diagram for ER inefficiency brief. Use it with E1-E3; it is a model or context image, not experimental or patient data. What to notice: Trace the labeled system, test, or design relationship and identify which evidence should trigger revision.
- Observe or measure the relevant feature in ER inefficiency brief.
- Organize the observation with a stable evidence ID.
- Apply this rule: A screening signal changes what to investigate next; it does not automatically prove the cause.
- Choose the option the evidence supports and state the limit of the conclusion.
Real biomedical example: You found the bottleneck and mapped who it hurts. Now write the one sentence that names your ER inefficiency so precisely that a stranger reading it knows exactly what to fix and who is being harmed by not fixing it.
What the evidence supports: E1-E3 and F1 support the daily take-home when the response meets the stated success criteria.
What it cannot prove: The package does not support claims beyond this lesson's or any real patient diagnosis.
- • : Sorting patients by urgency so the sickest are treated first, a core emergency-care skill and a HOSA event topic.
- • stakeholder: Any person or group affected by a project or decision, such as users, patients, families, or the team building a solution.
- • system: A set of parts that work together as a connected whole, where a change in one part can affect the others, such as an or a designed device.
- • constraint: A limit or requirement that a design must work within, such as a budget, available time, materials, or rules.
- • : The ordered sequence of steps and handoffs used to carry a task from start to finish in a consistent, repeatable way.
- • inefficiency: A situation where a process wastes time, energy, or resources, producing less useful output than the input should allow.
Use it now: Choose one decision option. Cite E1 and E3, then explain how the rule connects the evidence to your choice.

How to transform a bottleneck observation into a one-sentence design problem statement.
Limit: E1 supplies context or an observation; it does not by itself establish the explanation.
A design problem must be specific, observable, and tied to real harm so that it can guide a real solution, because a vague problem gives the designer nothing measurable to build or test against.
Limit: E2 is a teaching statement or comparison and must be checked against the task evidence.
Your brief names a specific, evidence-based inefficiency.
Limit: E3 supports only the result or product criterion named here; it cannot justify a broader clinical or causal claim.
PLTW-BFH-2027-02-09 · Simulated classroom evidence scenario
Your role: biomedical design team member
Decision: Your team must decide what the evidence from ER inefficiency brief supports before submitting the claim-evidence-reasoning response named on the lesson page.
- • Keep the current design.
- • Revise the feature that misses a criterion.
- • Run one more fair test before choosing.
Response: State one choice, cite at least two evidence IDs, explain the rule that connects them, and add one limitation. Submit it as the claim-evidence-reasoning response.
Claim ceiling: The supplied lesson evidence can support an observation, pattern, classroom mechanism, or next-step decision about ER inefficiency brief. It cannot by itself prove causation, establish a real clinical diagnosis, or justify action outside this classroom task.
Reason for review: Your team must decide what the evidence from ER inefficiency brief supports before submitting the claim-evidence-reasoning response named on the lesson page.
Context: A well-framed design problem is specific, observable, and tied to real stakeholder harm, because vague problems can only produce vague solutions.
- • T1: Choose one bottleneck from your as the target problem.
- • T2: Describe the inefficiency with specific, observable detail.
- • T3: Explain which stakeholders it harms, using your map.
- • T4: State the inefficiency as a one-sentence design problem.
- • T5: Submit the ER inefficiency brief as the weekly summative.
- • E1: How to transform a bottleneck observation into a one-sentence design problem statement.
- • E2: A design problem must be specific, observable, and tied to real harm so that it can guide a real solution, because a vague problem gives the designer nothing measurable to build or test against.
- • E3: Your brief names a specific, evidence-based inefficiency.
Measurements: Use only the measurements, units, graph, or counts supplied in today's task. No additional patient measurement is implied.
Figure finding: Teaching diagram for ER inefficiency brief. Trace the labeled system, test, or design relationship and identify which evidence should trigger revision. This is a teaching model, not patient or experimental data.
Uncertainty: This is a composite classroom scenario. Missing history, measurements, or confirmation tests remain unknown and limit the conclusion.
Mean = sum of values / number of values. Median = middle ordered value. Range = maximum - minimum.
For 2, 4, 4, and 10: mean = 20 / 4 = 5, median = 4, and range = 10 - 2 = 8.
Mean, median, and range keep the measurement unit. Order the values before finding the median.
Calculate the requested summary for today's supplied values, then write what it reveals and what it hides.
- • The solution must address the stated need in ER inefficiency brief.
- • The decision must be supported by E1-E3.
- • The final product must make the success criteria visible.
- • Complete the work inside the 80-minute block.
- • Use only supplied or teacher-approved materials and evidence.
- • Do not trade , accessibility, or privacy for speed.
- • and evidence quality: must pass before scoring other criteria.
- • User need and effectiveness: highest scored criterion.
- • Time, cost, and ease of use: compare only after and effectiveness pass.
Test evidence: For each option, record the E1-E3 result that supports or fails each criterion. Do not assign a score without a named observation.
- Version or option tested
- Criterion met or missed
- Evidence ID and result
- Revision made
- Reason for the revision
- Need and user
- Criteria and constraints
- Chosen option and evidence
- Test result
- Revision and reason
Students often think Students think a bigger, broader problem statement is a stronger one, so 'the ER is inefficient' sounds more important than a narrow claim.. The trap: The trap is that a broad statement gives a designer nothing to build toward, because you cannot solve 'inefficient' but you can solve 'one nurse creates a 45-minute wait for the sickest arrivals.' Specific and observable beats big, since a problem you can measure is a problem you can test a solution against.
Worked CER on a parallel case: school health office medication window\n\nUse this as a format model only. It solves a different problem than yours (a school health office, not an ER), so copy the structure and depth, not the content.\n\nObservation (specific and measurable): In our two-week log of the school health office, students who needed a scheduled midday medication waited an average of 12 minutes to be seen because a single nurse was also handling walk-in injuries and phone calls, and the medication cabinet could only be opened by that one nurse.\n\nStakeholders harmed (from my map): students on daily medication (missed class time and doses given late), teachers (students returning mid-lesson and disrupting instruction), and the nurse (interrupted constantly and unable to document care accurately).\n\nWhy this is the target: the single-key medication cabinet, not the number of students, is the limiting step, because every scheduled dose funnels through one person, so it is the highest-impact bottleneck.\n\nOne-sentence design problem: Design a midday medication workflow so that students with scheduled doses are seen within 4 minutes during a fixed dispensing window, reducing missed class time without hiring a second nurse.
This model shows the level of evidence and organization needed to complete: A parallel-case model that pins down one observed inefficiency in a school health office, links it to the stakeholders it harms, and reframes it as a one-sentence design problem, so students can copy the format without copying the answer.
