Problem Definition
CivicBridge is a mid-size U.S. city with a population of 450,000. Its transit authority operates the city's entire public bus network, which serves as the sole form of mass transit — there is no rail, subway, or light rail infrastructure. Since 2019, bus ridership has declined by 35%, from approximately 65,000 daily riders to 42,000.
The transit authority is running an annual operating deficit of $28 million. Its reserve fund currently holds $42 million, which at the current burn rate will be exhausted in approximately 18 months. If the reserve runs out, the authority will be forced into emergency service reductions under state law, requiring cuts to at least 40% of routes with only 30 days' notice.
The city council has hired your firm to evaluate four options: cutting underperforming routes, raising fares, pursuing new tax revenue, or fundamentally redesigning the system. The situation carries significant equity and political dimensions — 62% of current riders are low-income residents with no car alternative, and the mayor faces re-election in 14 months. What approach would you recommend to close the $28M deficit while preserving essential service for dependent riders?

Question 1Structuring
Prompt: "How would you structure your approach to evaluating the transit authority's options and developing a recommendation for the city council?"
Hint · Structuring
Build 3–4 branches that are specific to this client and question, not a generic framework. Check they don't overlap and together cover the problem.
Try it first, then checkShow model answerHide model answer
Possible Answer Structure
- Immediate deficit reduction (0-6 months): Revenue optimization and targeted cost savings that do not require council votes or union negotiation
- Structural reform (6-18 months): Network redesign, fare restructuring, and partnership renegotiation requiring stakeholder buy-in
- Sustainable funding (12-24 months): Long-term funding mechanism (tax, federal grants, regional partnerships) that outlasts the current crisis
- Cross-cutting: Stakeholder management plan mapping each action to political feasibility and equity impact
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate uses a standard revenue-vs.-cost framework. Identifies levers such as raising fares, cutting routes, and reducing labor costs. Lists the four options the city council mentioned. Framework is logical but generic — could apply to any organization with a deficit.
Level 1 (Surface): "We need to look at ways to increase revenue and decrease costs."
Strong (4): Candidate customizes the framework to the public sector context. Separates the analysis into short-term survival (close the 18-month funding gap) and long-term sustainability (structural reform). Identifies stakeholder groups — low-income riders, university, union, taxpayers, city council — and maps their interests. Recognizes that political feasibility is a real constraint, not just a footnote.
Level 2 (Implication): "The 18-month reserve timeline means we need a two-phase approach: immediate measures to buy time, then structural changes that require longer political and operational lead time."
Excellent (5): All of the above, plus the candidate introduces creative dimensions. Considers that the four options presented by the council are not mutually exclusive — a portfolio approach may dominate any single lever. Questions whether the current network design is optimized (e.g., hub-and-spoke vs. grid). Raises the idea of partnership models (university cost-sharing, private-sector sponsorship, regional coordination with the neighboring county). Flags the union contract renewal as both a risk and an opportunity to restructure labor costs. Frames the political timeline as a sequencing constraint — which actions build support before the election vs. which require post-election political capital.
Level 3 (Actionable): "We should sequence actions so that visible service improvements land before the election while structural cost reforms negotiate through the union contract window — these two timelines actually align."
Question 2Numeracy
Prompt: "The transit authority is considering renegotiating its student semester pass program with the university. Let me share the current and proposed terms."
Hint · Numeracy
Write the formula before you plug in numbers, keep units and zeros explicit, and sanity-check the order of magnitude at the end.
| Parameter | Current | Proposed |
|---|---|---|
| Enrolled students | 30,000 | 30,000 |
| Semester pass price | $100 | $250 |
| Student participation rate | 80% | 60% |
| Semesters per year | 2 | 2 |

Step-by-Step Solution
Step 1: Current annual revenue
| Calculation | Result | |
|---|---|---|
| Participating students | 30,000 x 80% | 24,000 |
| Revenue per student per year | $100 x 2 semesters | $200 |
| Total annual revenue | 24,000 x $200 | $4,800,000 |
Step 2: Proposed annual revenue
| Calculation | Result | |
|---|---|---|
| Participating students | 30,000 x 60% | 18,000 |
| Revenue per student per year | $250 x 2 semesters | $500 |
| Total annual revenue | 18,000 x $500 | $9,000,000 |
Step 3: Net revenue impact
| Value | |
|---|---|
| Proposed revenue | $9,000,000 |
| Current revenue | $4,800,000 |
| Net annual increase | +$4,200,000 |
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate completes the math correctly and states the $4.2M increase.
Strong (4): Candidate contextualizes the result — $4.2M closes only 15% of the $28M deficit. Meaningful but far from sufficient as a standalone measure. Notes that 6,000 fewer student pass holders may allow Route 7 service frequency reductions, yielding additional cost savings.
Excellent (5): Candidate flags second-order effects: (a) some of the 6,000 dropouts may switch to individual tickets, generating partial offsetting revenue; (b) the university may resist a 150% price increase, so the negotiation itself carries risk; (c) reduced student ridership could push Route 7's cost recovery even lower in the short term if costs are fixed, making it appear worse in performance reviews and potentially triggering premature route cuts. Recommends modeling a range of price points (e.g., $150, $200, $250) to find the revenue-maximizing level.
Question 3Judgement & Insights
Prompt: "Please review Exhibits A and C. What stands out to you, and what does it imply for our recommendation?"
Hint · Judgement & Insights
Read the exhibit title, axes and units first. Lead with the ‘so what’, then back it with one or two numbers.

What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate identifies that Route 7 has the worst cost recovery despite the highest ridership, and that the deficit has grown over time. Notes that fare revenue declined with ridership.
Level 1 (Surface): "Route 7 is the most expensive route relative to its fare revenue, and the overall deficit has tripled since 2019."
Strong (4): Candidate connects the two exhibits. Recognizes that the 2022 federal grant spike ($30M) was temporary COVID relief that masked the structural problem — no permanent fixes were implemented during that window. Identifies the state grant elimination ($8M annual loss) as a discrete shock accounting for nearly 30% of the current deficit. Observes that Route 22 has similarly poor cost recovery (31%) but carries far fewer riders, making it a lower-political-risk cut candidate.
Level 2 (Implication): "The real story is not ridership decline — it is a funding structure collapse. State grants disappeared, federal COVID money dried up, and the authority used that window to maintain the status quo instead of reforming. Even if ridership fully recovered to 2019 levels, the funding gap would still be $15-20M."
Excellent (5): Candidate identifies the Route 7 trap: it appears to be the obvious cut target (worst cost recovery at 28%, highest absolute cost gap of $13M), but cutting it would alienate the university — the city's largest employer with 8,500 jobs. The solution is to renegotiate the student pass and restructure Route 7's service design, not eliminate it. Also notes the "Other (14 routes)" category has just 16% cost recovery while consuming $37M in costs — this is where the real efficiency opportunity hides. Consolidating the weakest of those 14 routes could yield significant savings with far less political backlash than touching Route 7 or low-income corridors.
Level 3 (Actionable): "Route 7 is a trap — the math says cut it, but the politics say restructure it. The real savings are in the long tail of 14 unnamed routes consuming $37M at 16% recovery. That is where we should focus cuts."
Question 4Synthesis
Prompt: "The city council meets tomorrow. They want a clear recommendation. What do you advise?"
Hint · Synthesis
Answer first: the recommendation, two or three reasons with numbers, then risks and next steps.
What the interviewer is looking forShow guidanceHide guidance
Good (3): Candidate recommends a combination of fare increases and route cuts targeting the worst-performing routes. Acknowledges the equity concern but does not offer a specific mitigation plan. Recommendation is directionally correct but lacks prioritization and sequencing.
Strong (4): Candidate presents a phased plan. Phase 1 (immediate): renegotiate the university pass, consolidate the weakest 3-4 of the "Other" routes, and freeze non-essential capital spending. Phase 2 (6-12 months): redesign the route network around high-ridership corridors, negotiate labor efficiencies through the union contract renewal. Phase 3 (12-18 months): pursue a regional transit funding mechanism with the neighboring county. Explicitly preserves Route 3 (Medical District) and low-income-heavy routes. Acknowledges that no single lever closes the full gap.
Excellent (5): All of the above, plus the candidate frames the recommendation around the political timeline. Sequences visible service improvements (better frequency on remaining routes, new express options) to land before the 14-month election window. Positions the university pass renegotiation as a "partnership" narrative rather than a price hike. Proposes converting the weakest suburban routes to on-demand micro-transit (lower cost, maintains coverage, modern positioning). Quantifies the portfolio impact:
| Lever | Estimated Annual Impact |
|---|---|
| Student pass renegotiation | +$4.2M revenue |
| Consolidation of weakest "Other" routes (4-5 routes) | +$10-12M cost savings |
| Modest base fare adjustment ($1.75 to $2.00) | +$2-3M revenue |
| Regional ride-share partnership with neighboring county | +$3-4M cost sharing |
| Total | $19-23M (70-80% of gap) |
Acknowledges the remaining $5-9M gap requires either a future ballot measure or continued federal advocacy, and recommends building public support through demonstrated efficiency gains before returning to voters.
