Hi,
Suggest the following:
1. Understand the business context
• Read the case carefully and identify the business goals and pain points
• Clarify which stakeholders are involved and what their priorities might be

2. Define your architecture approach
• Start with high-level architecture (current vs. target state)
• Consider application, data, infrastructure, and security layers
• Identify key trade-offs (e.g., scalability vs. cost)

3. Address tech constraints & requirements
• Align the proposed architecture with known constraints (e.g., legacy systems, cloud migration, compliance)
• Mention relevant frameworks (e.g., TOGAF, Zachman) if helpful

4. Structure your recommendation
• Present a clear roadmap (phased if needed)
• Highlight benefits (e.g., agility, integration, cost optimization) and key risks

5. Practice communicating your solution
• Be concise and structured, interviewers assess clarity and thought process
• Prepare to answer follow-up questions on assumptions, impact, and alternatives

I have experience in enterprise architecture, so happy to review your material.

Hey there 😊

great that you’re preparing early – that’s already a big win! For a Tech Case Study in an Enterprise Architect role, here’s a quick plan 🧩:

  1. Read the case thoroughly – highlight key business and tech drivers.
  2. Identify core challenges – e.g. scalability, integration, legacy systems.
  3. Create a structured framework – think in layers: business, application, data, infrastructure.
  4. Prepare clear trade-offs – especially around build vs. buy, cloud vs. on-prem, etc.
  5. Practice presenting clearly – they’ll assess how you structure and communicate solutions 🎯

Happy to support you 1:1 with a tailored mock case or feedback session! 🧑‍💻🚀

Best, Alessa
