Built for MBAX 6007, this stock and flow map sorts a staffing agency's variables into four stocks and their flows, demoting the staffing gap to a calculated difference. Searches like "mbax 6007 week 3 assignment example", "mbax6007 week 3 sample" and "mbax 6007 week 3 example" land here.
What a finished MBAX 6007 Week 3 stock and flow map looks like
A one-page map, then three pages of explanation and a short reclassification table. Four stocks appear as boxes: applicants in screening, caregivers in training, active caregivers and clients on service. Valves on the pipes between them mark the flows: applications, clearances, training completions, quits, admissions and discharges. Fatigue appears as a fifth, softer stock, filled by overtime and drained by rest. The staffing gap is drawn as an auxiliary variable computed from two quantities, hours clients need and hours active caregivers can give. The explanation takes each stock in turn, stating its units, what fills it, what drains it and roughly how long material sits inside, with every duration marked illustrative. The table lists each variable from the Week 2 diagram, its old treatment and its new one, and gives the reason for every change.
How a MBAX 6007 Week 3 example is structured
Stocks are placed on the page in the order material moves through the agency, from application to active service, so the map can be read left to right like a pipeline. Forrester's original vocabulary of levels and rates sits behind the method: a level is whatever could be counted if time stopped, and a rate is what changes it. The explanation applies that test to each variable aloud, which is how the staffing gap loses its box. Units are stated for every stock and flow because mismatched units expose errors that shapes conceal. Fatigue is included as a soft stock with a caveat, since it cannot be counted directly yet clearly accumulates. The reclassification table closes the map and faces backward on purpose: it shows the reader what the rough diagram got wrong, which demonstrates the distinction this week is built to test.
Four boxes in pipeline order
Applicants in screening, caregivers in training, active caregivers and clients on service run left to right, so the map reads the way an aide moves through the agency.
Levels and rates
Forrester's early terms for stocks and flows give the map its test: a level can be counted at an instant, and a rate describes change across time.
The gap loses its box
Staffing gap becomes an auxiliary, the difference between hours needed and hours available. Drawing it as a stock would have implied it could fill up by itself.
Fatigue, with a caveat
Overtime fills it and rest drains it. The map keeps fatigue as a soft stock and says plainly that it is estimated, not measured.
Old treatment, new treatment
Every variable from the rough diagram is listed with its reclassification and a reason, which puts the week's central distinction on the page.
Where marks go in MBAX 6007 Week 3
Classification is where a stock and flow map wins or loses its marks. Maps that draw turnover as a box, or place active caregivers on a pipe, show the reader that the distinction between accumulations and rates has not landed, and the error usually spreads into every later week. The sample's reclassification table exists to prove that it has. Units receive attention: a flow in caregivers per month feeding a stock counted in hours signals confusion even when the shapes are right. The explanation earns credit when each stock's inflows, outflows and residence time are stated, rather than when the map is described generally. Soft variables are acceptable if flagged. An ambitious map with twelve stocks usually scores below a correct one with four, since every extra box is another place to be wrong.

MBAX 6007 Week 3 questions, answered
How do I tell a stock from a flow?
Imagine stopping time and asking what could still be counted. Caregivers on the roster, applicants waiting for background checks and clients receiving visits can all be counted at an instant, so they are stocks. Hiring, quitting and admissions only exist across an interval, so they are flows. The sample applies this test to every variable aloud, which is how the staffing gap stopped being a stock.
Can soft variables like fatigue be stocks?
Yes, if they accumulate and drain, and if you say how you would estimate them. The sample treats fatigue as filled by overtime and emptied by rest, and marks it as estimated rather than measured. Many instructors accept soft stocks when they are flagged honestly. Leaving out something that clearly accumulates, just because it is hard to count, often weakens the map more than including it.
What is an auxiliary variable?
A quantity calculated from stocks and flows at each moment, without accumulating anything itself. The sample's staffing gap is one: hours clients need minus hours active caregivers can give. Auxiliaries make a map readable by naming the comparisons that drive decisions. Drawing one as a stock is a common error, because it suggests the quantity could build up independently of the stocks it is computed from.
