Growth Strategy Before the Operating Model Is Fixed
Sakura Care is a 12-store regional chain of day-service centers for elderly clients, with revenue of ¥3.1 billion and an EBITDA margin of 9%, down from 14% in three years. The founder, age 71, wants to open four new stores next year and has asked your firm for a growth strategy. You have six weeks and a ¥6 million budget. Available data: store-level revenue and payroll, but no client-acuity, utilization, or referral-source data; three stores opened in the last 18 months are at 48% utilization; existing stores average 76%; staff turnover is 23%; public reimbursement rates are flat; the founder’s daughter is COO but has no authority over store managers; a bank is willing to lend for expansion if EBITDA margin returns above 12%. The founder has already signed a non-binding letter of intent for one new site. He is impatient with analysis and says “we just need more locations.”
1. Design a six-week diagnostic and decide whether to support the four-store expansion. Show how you would reframe the question and what analyses you would prioritize.

Reframe the question from “How do we open four stores?” to “What unit economics and operating model must be fixed so that expansion creates value rather than dilutes margin?” The diagnostic should test three hypotheses: margin decline is driven by store maturity and utilization; staff turnover and weak store authority are raising labor cost and reducing quality; and the referral pipeline is not sufficient to fill new stores quickly.
Week 1: interviews with the founder, COO, store managers, and bank; collect store-level P&L, payroll, client counts, and referral logs. Week 2: store visits and cohort analysis-compare the three new stores with mature stores on utilization, revenue per client, payroll per client, and ramp time. Week 3: unit economics-calculate store contribution and payback under 48% and 76% utilization; estimate the EBITDA gap of 5 points, about ¥155m, and trace it to labor, utilization, or pricing. Week 4: demand and referral assessment-map referral sources, competitor density, and catchment demand for the proposed sites. Week 5: staffing and governance-test whether the COO can control store managers and whether turnover is concentrated in new stores. Week 6: scenario model and board decision.
I would not support unconditional expansion. The evidence points to fixing the existing model first, then expanding through a gated pilot. The signed letter of intent should be treated as an option, not a commitment.
2. How would you handle the founder’s impatience and the signed letter of intent while maintaining consulting independence?
Read the worked answer
Acknowledge the founder’s ambition and the legitimate logic of growth, then make the risk concrete in his language: at 48% utilization, each new store may consume cash for 18–24 months and push the bank’s 12% EBITDA condition further away. Use a short scenario table showing cash and margin under three paths-open four stores now, fix and open one pilot, and defer all expansion. This turns the debate from “analysis versus action” into a choice among outcomes.
On the letter of intent, clarify that it is non-binding and identify the conditions and deadlines. Recommend negotiating an extension or a contingent commitment tied to a pilot gate. Do not sign or endorse the LOI on the client’s behalf. If the founder insists on proceeding, document the disagreement and set decision gates: site-level pre-sales, staffing plan, and a break-even model must be approved before any lease is signed.
Maintain independence by basing recommendations on agreed criteria, not on the founder’s preferred answer. Offer a quick win in the first two weeks-such as a store-level dashboard or a referral campaign-to show progress while the diagnostic continues.
3. Define three expansion-readiness metrics with thresholds and explain why each matters.

Mature-store EBITDA margin ≥12%. This is the bank’s lending condition and the proof that the core model can fund growth. Measure on a trailing-three-month basis, excluding one-off subsidies. If mature stores cannot reach 12%, new stores will dilute group margin further.
New-store utilization ≥70% within 12 months. The three recent stores are at 48%, which suggests a ramp or demand problem. A 70% threshold tests whether the referral pipeline and sales process can fill capacity before fixed costs overwhelm contribution.
Staff turnover <18% and store-manager authority clarified. Turnover at 23% raises recruiting and training costs and threatens service quality. Expansion should not proceed until the COO has explicit authority over store managers, a staffing model for new sites, and a turnover action plan. Secondary metrics should include referral conversion, revenue per client, and payback under five years. These thresholds convert the founder’s growth ambition into a gated investment case.
