Welbourne and its figures are composite; the logic model structure, the assumptions and the research cited are real.
Chain One: What the Program Delivers
1. Inputs: 148,000 dollars over two years, 1.0 full-time equivalent coordinator, 0.4 of a public health nurse, fire department installation time, 2,400 guards at 38 dollars each, interpretation services, the trauma center's 18,000 dollar prevention budget.
2. Activities: recruit buildings through landlord associations and tenant referrals; obtain written landlord consent; install guards in units with children under six; explain at the door that an insect screen is not a barrier; record every window by unit.
3. Outputs: 2,400 guards installed in 800 units across the four tracts; 800 doorstep conversations; one unit-level window register; 12 landlord agreements covering an estimated 290 units.
4. Short-term outcomes, 0 to 12 months: guard prevalence above the first floor in the four tracts rises from 4 percent to 35 percent in participating buildings; the share of parents in participating units who say a screen will hold a child falls below 20 percent.
5. Medium-term outcomes, 12 to 24 months: guards remain in place and functional at 90 percent of installed windows at a one-year check; two landlord associations adopt guards as a standard turnover item.
6. Long-term outcome, beyond the grant: falls from windows among children under six in the four tracts decline.
Chain Two: What the Program Requests
1. Inputs: coordinator time, the steering group's standing, the fire marshal's testimony, the trauma center's data.
2. Activities: prepare a code amendment extending the guard requirement to buildings with two or more units; brief council members individually; present the injury data at one public hearing; supply model language from cities that have done it.
3. Outputs: a drafted amendment, nine individual briefings, one hearing presentation, one legal review completed by the city solicitor.
4. Outcome the program cannot deliver: council adoption of the amendment.
5. If adopted, the medium-term outcome: guards required at change of occupancy in roughly 11,400 units, which is fourteen times the program's own installation capacity.
The program can install 800 units in two years. The code would reach 11,400. The chain the program does not control is the one that matters most, and the model says so on its face.
Assumptions, Written Out
1. That landlords will consent when the guard is free and installation is done for them. The assessment found four tenants who had asked and one who received, so consent is the chain's weakest link rather than a formality.
2. That guards remain in place. Removal for window cleaning or air conditioner installation is the documented failure mode, which is why a one-year check is an output rather than an afterthought.
3. That guards do not impede fire egress. The model specifies guards that release from inside without a tool, and the fire marshal's sign-off is a prerequisite activity rather than an endorsement.
4. That the four tracts are where the risk is. This rests on nine cases, which is thin, and the model names it as an assumption rather than a finding.
5. That installing a guard changes the outcome. This is the only assumption with strong external evidence behind it, from the program that first demonstrated the effect at city scale (Spiegel & Lindaman, 1977).
External Factors the Model Does Not Control
Summer temperature, which drives window opening. The rental market, since a tight market makes tenants reluctant to ask landlords for anything. Turnover, which both creates the moment to install and removes the families who were taught. And any change in the city's budget, since the coordinator is grant-funded and the fire department's time is in-kind.
How the Model Will Be Used
1. The outputs column becomes the monitoring report, due quarterly.
2. The short- and medium-term outcomes become the evaluation design's measures, which is why each carries a number and a date.
3. The long-term outcome is stated and explicitly not promised within the grant, because nine events in four years cannot be shown to decline in two.
4. The assumptions become the risk register, reviewed at six months.
What a Reader Should Check in This Model
Three things, which are where logic models usually fail. Whether each output is countable: here every one is a number the program will hold. Whether the outcomes are the program's own or borrowed from the literature: the first two are measured locally, the long-term one is borrowed and labeled. And whether the arrows survive scrutiny, meaning whether the link between an output and an outcome is plausible without a further unstated activity. A model built this way can be read as a theory to be tested rather than a plan to be admired, which is what program planning frameworks ask of it (Bartholomew et al., 1998). The evaluation unit later checks the same links, and the RE-AIM dimensions, especially adoption by landlords and maintenance of installed guards, are already visible in the medium-term row (Glasgow et al., 1999).

Reading the PU 605 Unit 4 instructions
Unit 4 usually asks for a logic model for your own program. Draw separate chains where a program delivers some results and can only request others, because a single chain lists a council vote beside an installation as though you controlled both. Put numbers in the inputs and outputs so each is countable. Separate short, medium and long-term outcomes, and state which ones the grant period cannot deliver. Write the assumptions as sentences that could be false, then name external factors outside your control. Say how the model will be used, meaning which column becomes the monitoring report and which becomes the evaluation. Finish by telling a reader where to look for its weak points.
How the PU 605 Unit 4 example is put together
The model on this page gives chain one from inputs through activities, outputs and three tiers of outcome, each with a figure and a date. Chain two carries the code amendment and ends at an outcome the program does not control, with a highlighted line comparing 800 units against 11,400. A margin note explains why two chains rather than one. Five assumptions follow, each written to be falsifiable, including landlord consent and guard retention, and a second note marks that style. External factors, summer temperature and the rental market among them, come next. The closing section lists three things a reader should check, flagged by a third note.
Where the points sit in the PU605 Unit 4 rubric
Credit here follows honesty about control. Separating delivered from requested results earns substantial marks, since models that promise a policy outcome as an output are the commonest fault. Points go to countable outputs with figures, and to outcomes tiered by time with the long-term one explicitly not promised inside the grant. Assumptions written as falsifiable statements score well, especially where the weakest link is identified. Naming external factors is expected. Marks follow for saying which column becomes monitoring and which becomes evaluation, since that is what makes the model usable. A closing section inviting a reader to test the arrows is rewarded.
PU605 Unit 4 help from the desk
The usual error is one chain containing a council vote, a signature or a funder decision as if the program produced it. Split the chains. The second is outputs with no numbers, which cannot be monitored. Third, do not promise the long-term outcome inside a two-year grant when the event is rare, because the evaluation will then be judged against a claim nobody can meet. Avoid assumptions phrased as truths; write them so they can fail. And do not borrow outcomes from the literature without labeling them as borrowed rather than measured locally. We can build the model for your own program if you send the prompt. One further check before you submit: make sure every arrow survives a reader asking what else would have to happen, because a hidden activity between an output and an outcome is where most models quietly fail.

PU605 Unit 4 questions, answered
Where can I find a free PU605 Unit 4 sample paper?
Both chains, with assumptions and external factors, are published on this page.
Why draw two chains?
Because one of them ends in a decision somebody else makes. A single chain would list a council vote as an output of the program.
What makes an output countable?
A number the program itself will hold, such as 2,400 guards, 800 units, 12 landlord agreements and one window register.
Should the long-term outcome appear?
Yes, stated and not promised. Nine falls in four years cannot be shown to decline inside two years, and the model says so.
How should assumptions be written?
As sentences that could turn out false, with the weakest one identified. Here it is landlord consent rather than installation capacity.
