Most digital transformation cases in consulting interviews focus on whether a company should transform. Execution cases flip the question: the decision is made — now how does the organization actually deliver? Based on our experience with 200+ technology cases, execution-focused questions separate top candidates because they test operational thinking, stakeholder management, and the ability to define measurable progress in ambiguous environments.
Why Execution Cases Are Increasing in Frequency
Consulting firms like McKinsey, BCG, and Bain have shifted their digital practices from strategy-only to strategy-through-implementation. McKinsey Digital now deploys engineering teams alongside strategists. BCG X builds products with clients. This shift means interviewers increasingly want to know if you can think past the PowerPoint.
Execution cases typically present a scenario where:
| Scenario Type | Example Prompt | What’s Really Being Tested |
|---|---|---|
| Stalled transformation | “The client launched a $50M digital program 18 months ago with minimal adoption — what’s wrong?” | Root cause diagnosis, stakeholder analysis |
| Phased rollout | “How should this bank sequence its digital migration across 200 branches?” | Prioritization, resource allocation, risk management |
| Build vs. buy vs. partner | “Should this retailer build a custom platform, buy SaaS, or partner with a tech company?” | Trade-off analysis, total cost of ownership |
| Change management | “The new ERP system is deployed but only 30% of employees use it — how do we drive adoption?” | Behavioral incentives, measurement, training design |
The Execution Framework: Five Layers
While digital transformation strategy cases use a top-down strategic lens, execution cases require a delivery-oriented framework. Structure your analysis around these five layers:

Layer 1: Scope and Sequencing
The most common mistake candidates make is treating transformation as a single monolithic project. In our experience coaching candidates, the best answers decompose the program into workstreams and sequence them based on value, feasibility, and dependencies.
Key questions to ask your interviewer:
- What has been attempted so far, and what were the results?
- Are there quick wins that can demonstrate value within 90 days?
- Which business units or geographies have the highest readiness?
Prioritization matrix for sequencing:
| Dimension | High Priority | Lower Priority |
|---|---|---|
| Business impact | Revenue-facing processes | Internal administrative tools |
| Technical readiness | Clean data, modern APIs | Legacy mainframes, fragmented systems |
| Organizational readiness | Leadership sponsorship, change appetite | Union constraints, recent restructuring |
| Dependencies | Standalone modules | Tightly coupled systems |
Layer 2: Technology Architecture Decisions
Execution cases often test whether you understand the real trade-offs in technology selection — not just cost, but speed-to-value, maintenance burden, and lock-in risk.
Build vs. Buy vs. Partner decision framework:
| Factor | Build | Buy (SaaS) | Partner |
|---|---|---|---|
| Time to value | 12-24 months | 3-6 months | 6-12 months |
| Customization | Full control | Limited to configuration | Moderate |
| Ongoing cost | High (engineering team) | Predictable subscription | Revenue share |
| Competitive advantage | Potential differentiator | Commodity capability | Shared innovation |
| Risk | Execution risk, scope creep | Vendor dependency | Alignment risk |
In our analysis of transformation cases, roughly 70% of companies over-invest in custom builds for non-differentiating capabilities. The best candidates identify where custom technology creates genuine competitive advantage versus where it simply adds cost and delay.
Layer 3: Organization and Talent
Technology transformations fail more often from people issues than technical ones. Based on our work with technology strategy cases, roughly 60-70% of stalled transformations trace back to organizational barriers.
Structure your talent analysis around three gaps:
- Skill gaps: Does the organization have the technical talent to execute? (Data engineers, cloud architects, product managers)
- Structure gaps: Is the operating model aligned? (Product teams vs. project teams, centralized vs. federated digital units)
- Capacity gaps: Can the organization absorb change while maintaining business-as-usual operations?
Layer 4: Change Management and Adoption
This is where most execution cases have their “aha” moment. The technology works — but nobody uses it. A strong answer addresses adoption through behavioral design, not just training.
The adoption equation:
Adoption = (Perceived Value × Ease of Use) / (Switching Cost + Habit Strength)
Levers to drive adoption:
| Lever | Mechanism | Example |
|---|---|---|
| Remove friction | Make the new way easier than the old way | Single sign-on, mobile access, auto-populated fields |
| Create incentives | Reward early adopters | Performance metrics tied to tool usage, gamification |
| Eliminate alternatives | Phase out legacy systems | Hard cutover dates with adequate preparation |
| Social proof | Make adoption visible | Leaderboards, peer champions, success stories |
| Executive modeling | Leaders use the new tools visibly | C-suite dashboards built on new platform |
Layer 5: Measurement and Iteration
Execution cases require you to define what “success” looks like at each stage. The best candidates distinguish between leading indicators (early signals) and lagging outcomes (ultimate value).
| Metric Type | Examples | When to Measure |
|---|---|---|
| Input metrics | Training completion, system uptime, data migration % | Weeks 1-4 |
| Adoption metrics | DAU/MAU, feature utilization, process compliance | Months 1-3 |
| Efficiency metrics | Cycle time reduction, error rates, manual workaround frequency | Months 3-6 |
| Value metrics | Revenue impact, cost savings, NPS improvement | Months 6-12+ |
Common Pitfalls in Execution Cases
Based on our analysis of candidate performance in operations-focused cases, these are the mistakes that cost candidates the most:
- Jumping to technology before understanding organizational readiness
- Ignoring the current state — assuming a blank slate when legacy systems and processes exist
- Binary thinking — proposing “big bang” launches instead of phased approaches
- Forgetting stakeholders — not identifying who wins and who loses from the transformation
- No measurement plan — proposing changes without defining how to track progress
Sample Case Walkthrough
Prompt: “A mid-size insurance company spent $80M on a claims automation platform. After 2 years, only 15% of claims are processed through the new system. The CEO wants to know what went wrong and how to fix it.”
Strong approach:
- Diagnose root causes — Is it a technology problem (system doesn’t work), an adoption problem (adjusters won’t use it), or a scope problem (system only handles simple claims)?
- Segment the gap — What types of claims can the system handle today? What percentage of total volume do they represent?
- Identify barriers — Interview adjusters: Do they trust the system? Is it faster than their current workflow? Were they trained adequately?
- Recommend phased fix — Start with claim types where automation delivers clear speed/accuracy gains. Build credibility, then expand scope.
Connecting to Other Case Types
Execution cases rarely exist in isolation. They often combine with:
- Profitability cases: Transformation ROI — does the investment generate adequate returns?
- Growth strategy cases: Digital as a growth enabler — new channels, products, or markets
- Technology industry cases: When the client is a tech company helping others transform
Key Takeaways
- Execution cases test operational thinking — the “how” of transformation, not the “whether”
- Structure your answer around five layers: scope/sequencing, technology architecture, organization/talent, change management, and measurement
- Always diagnose the current state before proposing solutions — most stalled transformations have specific, identifiable root causes
- Distinguish between technology failure and adoption failure — they require fundamentally different interventions
- Define metrics at each stage: input metrics early, adoption metrics mid-term, value metrics long-term
- The build vs. buy decision should be driven by competitive differentiation, not engineering ambition
