This MBAX 6007 Week 6 discussion post example hands a home-health staffing model to the class and points at its weakest joint rather than defending it. Walden MBAX 6007 rewards openness to correction this week, so the post compresses last week's two-stock model into three sentences and then names the assumption the author trusts least: steady demand. Discharge planners who remember refused referrals keep calling competitors for months, so demand may respond to the agency's own record and deepen the next surplus. Sterman's warning about treating a responsive variable as external frames the doubt. One narrow question asks whether referral memory belongs inside the model's boundary. Replies to Owen and Leah suggest tips as a missing driver of restaurant quits and appointment waits as a driver of clinic no-shows, citing Meadows and Senge, in a post written by a student in the Master of Business Administration (MBA).

Week 6 Discussion: Testing Each Other's Models

The Joint I Trust Least in My Staffing Model: Should Discharge Planners' Memory of Refused Referrals Sit Inside the Boundary?

Last week I built a two-stock model of Hearthside Home Care, the made-up home-health agency I have used all term: people move from a hiring pipeline into an active roster, and leave through quits at 4 percent a month. The hiring rule replaces expected quits and closes the gap between need and last month's roster over two months, while ignoring anyone still in screening or training. With demand held at 120 aides, the run overshoots to about 137 and swings back below need, which matches the shape of the agency's yearly cycle.

What this page is doingThe model is compressed to three sentences so classmates reach the open question quickly.

The relationship I trust least is the one I left out. My model treats demand as steady, as if hospital discharge planners send the same number of referrals whatever Hearthside does. In my experience they do not. When we turn referrals away in a shortage, planners remember. For months afterward they call our competitors first, even when we have aides to spare. If that is right, demand responds to our own record: a shortage today lowers referrals later, which deepens the surplus that follows the hiring wave and makes the next swing larger. Sterman (2000) warns that treating a variable as outside the model when it actually responds to the model's own behavior is one of the most common modeling errors, and I may have made it.

What this page is doingThe post names its own weakest assumption, which is what this week rewards.

So my question for the class is narrow: does referral memory belong inside my model's boundary, or is it a separate problem I should leave outside? Classmates whose organizations depend on referrals from people free to send them elsewhere would be especially helpful here. Even a rough sense of how long a referral source holds a grudge would help. If the answer is yes, I will need some way to estimate how long planners remember a refusal, which I suspect is longer than the shortage that caused it.

What this page is doingThe post asks one question, which gives classmates a target rather than a general invitation.

Reply to Owen

Owen, your restaurant staffing model holds the server quit rate constant. I wonder whether tips belong in it. In slow weeks, servers earn less in tips, and in my experience that is when they start looking elsewhere, so quits may rise exactly when the restaurant has too many servers for the covers it is serving. That would be a balancing loop much like the short-hours loop in my agency. Could you estimate tips per server per week from your sales data and test whether quits follow them?

What this page is doingThe first reply suggests a missing driver for a classmate's constant, the same kind of gap the post admits.

Reply to Leah

Leah, your clinic appointment model treats no-show rates as fixed, but you mentioned that wait times for appointments have grown. Patients who wait three weeks for a visit may be more likely not to show up, which would turn the no-show rate into something your own scheduling produces. Meadows (2008) suggests asking of every constant in a model whether it is really constant or just slow to change. Senge (1990) observes that today's problems often come from yesterday's solutions, and a long booking queue built to keep doctors busy may be one of those.

What this page is doingThe second reply questions a boundary choice in a classmate's model rather than its arithmetic.

Reading the MBAX 6007 Week 6 instructions

In Week 6 you share your model with classmates and invite correction. Summarize the model in a few sentences so readers reach your question quickly. Then name the relationship or assumption you trust least, and explain why it might be wrong, ideally with an example from experience. Connect the doubt to a modeling principle from the readings. Ask one specific question rather than inviting general comments, since a narrow question gets useful answers. In replies, look for a constant in a classmate's model that might actually respond to the model's own behavior, and suggest how they could test it. A main post near 420 words and two replies of about 160 is the usual size.

How this MBAX 6007 Week 6 example is built

The first paragraph summarizes the pipeline, the roster, the quit rate, the hiring rule and the base run's overshoot. The second names steady demand as the weakest assumption, describes planners' memory of refusals and cites Sterman on misclassified variables. The third asks whether referral memory belongs inside the boundary and invites classmates who rely on referrals, adding a note on estimating how long planners remember. The reply to Owen proposes tip income as a driver of server quits and suggests testing it against sales data. The reply to Leah suggests that long appointment waits may raise no-shows, citing Meadows on constants and Senge on yesterday's solutions.

Reading the MBAX 6007 Week 6 rubric

Model critique posts are graded on candor and on the quality of the question. Naming the model's weakest assumption, and explaining why it might fail, earns most of the credit. A concise model summary helps readers engage. Linking the doubt to a modeling principle shows understanding. One specific question scores higher than a general request for feedback. Replies are credited when they identify a plausible missing feedback in a classmate's model and suggest a feasible test, rather than offering praise. Posts that defend the model as finished, or replies that comment only on presentation, earn fewer marks. The tone should be open and collegial. Instructors notice when a reply suggests a test the classmate could actually run.

MBAX 6007 Week 6 help from the desk

Look at every constant in your model and ask whether it really stays fixed when the rest of the system changes. The one you feel least sure about is usually the one to name. Describe a real moment that made you doubt it. Then write a single question you want classmates to answer, such as whether a variable belongs inside the boundary. Keep the model summary to three sentences. When replying, read a classmate's model the same way and look for a constant that their own system might be pushing. A common shortfall is a post that asks for any feedback at all. If you are unsure which assumption to question, tell us about your model.

What question does the post ask the class?

Whether referral memory belongs inside the model's boundary or should stay outside.

What does the reply to Owen suggest?
