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 TypeExample PromptWhat’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:

    E --> E3[Incentive structure]
    F --> F1[Leading indicators]
    F --> F2[Adoption metrics]
    F --> F3[Value realization]

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:

DimensionHigh PriorityLower Priority
Business impactRevenue-facing processesInternal administrative tools
Technical readinessClean data, modern APIsLegacy mainframes, fragmented systems
Organizational readinessLeadership sponsorship, change appetiteUnion constraints, recent restructuring
DependenciesStandalone modulesTightly 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:

FactorBuildBuy (SaaS)Partner
Time to value12-24 months3-6 months6-12 months
CustomizationFull controlLimited to configurationModerate
Ongoing costHigh (engineering team)Predictable subscriptionRevenue share
Competitive advantagePotential differentiatorCommodity capabilityShared innovation
RiskExecution risk, scope creepVendor dependencyAlignment 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:

  1. Skill gaps: Does the organization have the technical talent to execute? (Data engineers, cloud architects, product managers)
  2. Structure gaps: Is the operating model aligned? (Product teams vs. project teams, centralized vs. federated digital units)
  3. 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:

LeverMechanismExample
Remove frictionMake the new way easier than the old waySingle sign-on, mobile access, auto-populated fields
Create incentivesReward early adoptersPerformance metrics tied to tool usage, gamification
Eliminate alternativesPhase out legacy systemsHard cutover dates with adequate preparation
Social proofMake adoption visibleLeaderboards, peer champions, success stories
Executive modelingLeaders use the new tools visiblyC-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 TypeExamplesWhen to Measure
Input metricsTraining completion, system uptime, data migration %Weeks 1-4
Adoption metricsDAU/MAU, feature utilization, process complianceMonths 1-3
Efficiency metricsCycle time reduction, error rates, manual workaround frequencyMonths 3-6
Value metricsRevenue impact, cost savings, NPS improvementMonths 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:

  1. Jumping to technology before understanding organizational readiness
  2. Ignoring the current state — assuming a blank slate when legacy systems and processes exist
  3. Binary thinking — proposing “big bang” launches instead of phased approaches
  4. Forgetting stakeholders — not identifying who wins and who loses from the transformation
  5. 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:

  1. 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)?
  2. Segment the gap — What types of claims can the system handle today? What percentage of total volume do they represent?
  3. Identify barriers — Interview adjusters: Do they trust the system? Is it faster than their current workflow? Were they trained adequately?
  4. 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:

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
