The lender, the vendor and every figure are composite and illustrative, carried from earlier units; the articles and textbook cited are real.

What this part is doingGiving the decision, the expected savings and the uncertain interval in the lead puts all three in front of the committee.

Memorandum

To: Credit Committee From: Credit Risk Analyst Date: June 2, 2026 Re: Whether to license the vendor scorecard for all branches

Decision

License the scorecard for all branches for one year at $140,000, under a stop rule: if the one-year default rate on loans approved in the first six months exceeds 4.8 percent, the license will not be renewed.

The Figures

Default rates. 5.29 percent on 2,400 loans approved under the old rules; 4.19 percent on 2,150 loans approved under the scorecard during the pilot. Difference: about 1.11 percentage points.

Value of each point. At an average loan of $38,000 and an average loss of 39.4 percent of the balance on default, each percentage point of default rate costs about $150 per loan in expected loss.

Savings per loan. 1.11 points times about $149.72, about $165.53.

Annual savings. About 4,300 loans a year times $165.53, about $711,800.

Net of the license. About $711,800 less $140,000, roughly $572,000 a year.

What Remains Uncertain

Statistical uncertainty. The 95 percent confidence interval for the reduction in default rate runs from about negative 0.13 to positive 2.34 points. In dollars, that means net savings anywhere from about negative $220,000, if the model actually made defaults slightly worse, to about $1.37 million.

Design uncertainty. The pilot compared loans approved in different years. Part of the drop in defaults may reflect a calmer economy rather than the scorecard. The interval above does not capture that risk.

Severity uncertainty. The 39.4 percent loss figure comes from 34 workout files, with its own interval of about 33 to 46 percent. At the low end, annual savings would fall by about $110,000.

The expected gain is large relative to the cost, but the evidence is one pilot compared with a different year, so the right decision is to license with a stop rule that limits the loss if the improvement turns out to be timing rather than the model.

What this part is doingThe highlighted sentence links the decision to its main uncertainty, the reasoning graders look for in a decision brief.

Why License Rather Than Wait

Waiting a year for a randomized comparison would cost the expected savings of that year, about $572,000, to reduce uncertainty. Licensing with a stop rule caps the downside at roughly one year's fee and the savings forgone if the model underperforms, while capturing the upside if it works. Decision analysis texts recommend this kind of staged commitment when an option to reverse is cheap and the expected value is clearly positive (Clemen & Reilly, 2014).

How the Stop Rule Was Set

A one-year default rate of 4.8 percent on the first six months' approvals sits about halfway between the old rate, 5.29 percent, and the pilot rate, 4.19 percent. With about 2,150 loans in six months, the standard error of the observed rate is about 0.43 points, so a true rate of 4.19 percent would produce an observed rate above 4.8 percent only about one time in thirteen. The rule gives the model a fair chance while catching a result close to the old rate.

Running a Cleaner Test at the Same Time

During the license year, the lender will score every application with both the old rules and the scorecard and record both decisions. Comparing default rates on loans that both approve, and on loans the two disagree about, will separate the model's effect from the economy's. Research on credit scoring evaluation stresses comparing models on the same applications at the same time for exactly this reason (Hand & Henley, 1997).

What the Committee Should Not Conclude

The pilot does not prove the scorecard causes fewer defaults, and the p-value of about 0.04 in the earlier test does not mean there is a 96 percent chance the model works. It means that if the model made no difference, a gap this large would appear by chance about 4 percent of the time (Wasserstein & Lazar, 2016).

Costs Not in the Savings Figure

The savings estimate excludes two costs. Staff training and system integration will take about 120 hours in the first quarter, roughly $15,000 of internal time. And the scorecard may decline some applications the old rules would have approved; if a few of those would have repaid, the lender loses their interest income. The pilot showed approval rates about 2 points lower under the scorecard, worth about $40,000 a year in forgone net interest on loans that would probably have performed.

Next Steps

Sign the one-year license, set up dual scoring in all branches next month, and report the six-month default rate to the committee as soon as the first cohort has been seasoned.

What this part is doingEnding with dual scoring and a reporting date shows the brief builds the evidence the decision still lacks.

Reading the GF 582 Unit 10 instructions

The final GF582 unit asks for a brief that turns statistical evidence into a decision. State the decision in the first sentence, with any conditions. Present the figures that support it, converting effects into dollars step by step. Then lay out what remains uncertain: statistical uncertainty from intervals, design uncertainty the intervals do not capture, and uncertainty in other inputs. Explain why acting now, waiting or acting with conditions is best, using decision reasoning. If you set a stop rule, explain how its threshold was chosen and how likely it is to be triggered by chance. Describe how evidence will be improved during the decision period. Warn the committee against the familiar mistake of reading a small p-value as the chance the vendor's claim is correct. Cite decision analysis and statistics sources in APA 7.

How this GF582 Unit 10 example is built

The brief's decision and stop rule come first. A figures section builds the value of each default point, the savings per loan, the annual total and the net figure. An uncertainty section converts the confidence interval into a range of net savings, flags the before-and-after design and adds severity uncertainty. The highlighted sentence links the stop rule to the design weakness. A section explains why licensing with a stop rule beats waiting, citing Clemen and Reilly. Another sets the 4.8 percent threshold and its chance of a false trigger. Dual scoring is proposed, citing Hand and Henley, and a warning on p-values cites Wasserstein and Lazar. Costs not in the savings figure precede next steps.

Reading the GF582 Unit 10 grading rubric

GF582 decision briefs earn most of their points for a clear decision supported by correct conversions from statistics to dollars. Graders check each step from default rates to annual savings. The largest analytical share rewards a complete account of uncertainty, separating statistical, design and input uncertainty and translating intervals into the decision's units. A reasoned choice among acting, waiting and acting with conditions shows judgment. Instructors in the MS in Finance program value stop rules with stated thresholds and false-trigger rates, and plans to gather better evidence. An accurate account of what a p-value says, a short format and Clemen and Reilly plus the scoring and p-value sources in APA 7 complete the rubric.

Common GF582 Unit 10 mistakes, and how to avoid them

Many final GF582 briefs present the expected savings and stop, leaving the committee unaware that the evidence could support a loss. Others reject action because a result is not overwhelming, ignoring the cost of waiting. Intervals are reported in percentage points instead of dollars. Design weaknesses outside the interval are not mentioned. Stop rules are set without explaining how often they would trigger by chance. P-values are described as the probability the vendor is right. For any decision your course builds toward, keep the brief's order: decision, figures, uncertainties in decision units, reasoning about timing, a calibrated stop rule, a plan for better evidence and next steps.

GF582 Unit 10 questions, answered

How much uncertainty belongs in a decision brief?

Enough that the reader knows the range of outcomes the decision could produce and what could make the evidence wrong. Translate intervals into the decision's units, dollars or defaults rather than test statistics, and name any uncertainty the statistics cannot measure, such as a confounded comparison. A brief that sounds certain usually signals missing analysis rather than strong data.

Can a brief recommend action when the result is not significant at 0.05?

Yes, if the reasoning is explicit. Significance thresholds control error rates in testing; business decisions also weigh the cost of acting against the cost of waiting. A brief can recommend a reversible action with a monitoring rule when expected value is positive and the downside is bounded. State that reasoning rather than letting the p-value decide alone.

What is a stop rule?

A condition, set before the results arrive, that triggers a review or reversal of the decision. It names the metric, the threshold, the sample on which it will be judged and who acts. Setting it in advance prevents the common habit of reinterpreting disappointing results after the fact, and it turns a one-time analysis into something the organization can learn from.

A complete GF582 Unit 10 statistical decision brief on licensing a credit scorecard is available here, with savings in dollars, uncertainty ranges, a stop rule and APA 7 references.

Why license now instead of waiting for better evidence?

Waiting would give up about a year of expected savings, roughly $572,000. A one-year license with a stop rule caps the downside while capturing the gain if the scorecard works.
