Week 7 Discussion: Peer Critique of Venture Models

Two Unsourced Inputs in a Fresh Pet Food Subscription Model: Peer Critiques Following the Acquisition Cost and the Monthly Retention Rate Through Everything That Depends on Them

Reply on Acquisition Cost

Jordan, your projection for a fresh pet food subscription assumes an acquisition cost of $45 per new subscriber, and the cell carries no source. Everything about payback depends on it. Using your own spreadsheet: each subscriber pays $68 a month and contributes $19 of margin after food, packaging and delivery, so at $45 the cost is recovered in about 2.4 months. If acquisition costs $90 instead, payback takes about 4.7 months, and with your assumed retention, a meaningful share of subscribers cancel before they have paid back their acquisition cost. At $90, your model's cash need in year one rises from $1.1 million to about $1.9 million, because you would spend twice as much to acquire the same subscribers before their margin arrives.

Two sources could replace the assumption. Your own paid advertising test, which spent $2,400 and produced 31 sign-ups, implies about $77 per subscriber, though a test that small is noisy and early buyers may be easier to reach. Annual reports of listed subscription meal and pet companies often disclose marketing spending and subscriber counts, from which a rough cost per subscriber can be built, though their brand recognition makes the figure a floor rather than an estimate for a new entrant. Kahneman and Lovallo (1993) warned that plans built from a venture's own details tend toward optimism, and the outside figures guard against that.

What this page is doingThe first reply names one input precisely and recomputes inside the classmate's own model rather than building a new one.

Reply on Monthly Retention

Your model assumes 92 percent of subscribers stay each month, which also has no source. That figure implies an average subscriber life of about 12.5 months. At 85 percent, average life falls to about 6.7 months, and lifetime margin per subscriber falls from about $238 to about $127. Gupta et al. (2004) showed that customer value depends heavily on retention, and in your model a seven-point change in monthly retention nearly halves the value of a subscriber.

A further point: a single retention rate treats all subscribers alike. Fader and Hardie (2010) showed that when customers differ in their propensity to cancel, applying one average rate to everyone understates the value of those who stay and overstates how quickly a cohort will thin out in later months. Your first cohort's actual month-by-month cancellations, even from 31 subscribers, would show whether early losses are concentrated among a few who leave quickly.

What this page is doingThe second reply also explains why a single average rate can mislead, which a classmate might not see.

Summary for Jordan

Neither critique says your numbers are wrong. Each says your case moves a great deal when one input changes, and each names evidence that could anchor it.

Reading the DDBA 8541 Week 7 instructions

In Week 7 you reply to a classmate's venture model by examining one input that arrived without a source. Quote the input and its cell or assumption. Recompute, using only the classmate's own model, how far the case moves when the input changes to a plausible alternative. Name where evidence for the input could come from and what each source can and cannot establish. In a second reply, do the same for a different input. Keep each reply near two hundred words, exacting about evidence and neutral about the person, and close with a short summary the classmate can act on.

How this DDBA 8541 Week 7 example is built

The first sample reply quotes the $45 cost per subscriber, uses the classmate's $68 monthly price and $19 margin to compute payback and shows how many subscribers would cancel before repaying their cost at $90. It proposes the classmate's own small advertising test and the disclosures of listed subscription companies, noting that established brands make their figure a floor. The second reply converts 92 and 85 percent monthly retention into average lives of 12.5 and about 6.7 months and adds that one average rate hides differences between subscribers, suggesting the first cohort's month-by-month cancellations as evidence. A closing line tells the classmate that neither critique says the numbers are wrong, only that the case moves a great deal with each.

Reading the DDBA 8541 Week 7 rubric

Graders look for one input, precisely identified; replies that question the whole projection or object to optimism in general give the classmate nothing to fix. Most credit rides on showing dependency inside the classmate's model, since that is what makes the critique matter. Proposed sources earn credit when each is described with its limits. Tone is marked too: a doctoral critique is exacting about evidence and neutral about the person. Replies lose credit for supplying a replacement number without evidence, or for building a new model that the classmate cannot reconcile with their own. Short, well-organized replies with figures stated plainly are easier for the classmate to act on, and that usefulness is part of the grade.

DDBA 8541 Week 7 help: mistakes that cost marks

Open the classmate's model and find the cells with no note or source. Pick the one that most changes payback, cash need or value. Change it to a plausible alternative and recompute using their formulas, not yours. Report what moved, and by how much, in a couple of plain sentences. Then think about where real evidence could come from, such as a small test, public company filings or industry studies, and say what each would and would not show. Keep the tone helpful. A summary line telling the classmate what to do next makes the critique useful. Remember that the classmate may know things about the venture you do not; frame your alternative as a test, not a correction.

DDBA 8541 Week 7 questions, answered

Where can I find a free DDBA 8541 Week 7 sample paper?

Both replies to Jordan on the pet food model, with every recomputed figure, fill the sample section at no cost.

Which inputs do the DDBA 8541 Week 7 replies examine?

The $45 acquisition cost per subscriber and the 92 percent monthly retention rate.

What happens if acquisition cost doubles?

Payback rises from about 2.4 to about 4.7 months and year-one cash need rises to about $1.9 million.

How much does retention matter?

Dropping from 92 to 85 percent cuts lifetime margin per subscriber from about $238 to about $127.

Why can a single retention rate mislead?

Subscribers differ, so one average rate misstates how quickly a cohort thins in later months.
