CTO Technology Strategy & Innovation 3 — Questions and Answers
Question 1: A CTO is managing a portfolio of technology investments. Which portfolio view best helps balance innovation bets with core maintenance spending?
- Horizon 1-2-3 framework (Correct answer)
- SWOT analysis
- Capability maturity model
- Value stream mapping
Correct answer: Horizon 1-2-3 framework
McKinsey's Three Horizons framework categorizes investments across core business (H1), emerging opportunities (H2), and transformational bets (H3) to balance short and long-term innovation.
Question 2: What is the primary risk of over-investing in Horizon 3 (transformational) innovation at the expense of Horizon 1 (core)?
- Too many patents are filed
- Core business performance degrades while future bets may not materialize (Correct answer)
- Engineers become too specialized
- Vendor relationships weaken
Correct answer: Core business performance degrades while future bets may not materialize
Neglecting Horizon 1 can erode the cash flows and operational performance that fund innovation, creating existential risk if H3 bets fail to pay off in time.
Question 3: Which organizational model places small, cross-functional product teams at the center of technology delivery, reducing handoffs and increasing ownership?
- Functional silo model
- Team Topologies stream-aligned teams (Correct answer)
- Center of Excellence (CoE)
- Matrix organization
Correct answer: Team Topologies stream-aligned teams
Team Topologies defines stream-aligned teams as long-lived, cross-functional teams owning end-to-end delivery of a specific value stream with minimal dependencies.
Question 4: A CTO discovers that 60% of engineering capacity is consumed by unplanned work and toil. What is the most strategic response?
- Hire more engineers immediately
- Conduct an investment audit and establish toil reduction targets (Correct answer)
- Outsource all maintenance work
- Pause all new feature development
Correct answer: Conduct an investment audit and establish toil reduction targets
Auditing where capacity goes and setting explicit toil reduction targets (e.g., SRE's 50% cap on ops work) frees engineering capacity for strategic innovation.
Question 5: Which of the following best describes 'technical strategy' as distinct from 'technology strategy'?
- Technical strategy focuses on which technologies to adopt; technology strategy focuses on architecture
- Technical strategy addresses internal system design and engineering practices; technology strategy aligns technology choices with business goals (Correct answer)
- They are synonymous terms used interchangeably
- Technical strategy is owned by developers; technology strategy is owned by the board
Correct answer: Technical strategy addresses internal system design and engineering practices; technology strategy aligns technology choices with business goals
Technology strategy aligns technology direction with business outcomes, while technical strategy governs the engineering approach, architecture, and practices used to build systems.
Question 6: When presenting a technology strategy to the board, a CTO should frame technology investments primarily in terms of:
- Lines of code delivered and system uptime
- Business outcomes, risk reduction, and competitive positioning (Correct answer)
- Technology stack choices and vendor names
- Number of engineers hired and team structure
Correct answer: Business outcomes, risk reduction, and competitive positioning
Board members focus on business value; technology strategy must be articulated through business outcomes, risk exposure, and competitive differentiation rather than technical metrics.
Question 7: What is 'platform thinking' in technology strategy?
- Choosing a single cloud provider for all workloads
- Building reusable, shared internal capabilities that accelerate multiple product teams (Correct answer)
- Standardizing on one programming language across the company
- Consolidating all data into a single database platform
Correct answer: Building reusable, shared internal capabilities that accelerate multiple product teams
Platform thinking involves creating internal developer platforms with reusable services, tools, and APIs that enable multiple product teams to build faster with less redundancy.
