Roleplay Scenario

Scenario Overview

Your team is in charge of a crucial yet outdated legacy system that's been causing headaches lately. It's running into performance issues, and customers aren't thrilled. You need to guide a team meeting to figure out how to fix these problems, plan for the future, and keep stakeholders calm without overpromising.

Roles & Setup

Role A – Technical Lead (You)
You're steering the ship and making sure everyone is aligned with the business goals.
Your goal: Lead the team to find quick wins, prioritize effectively, and communicate clearly with stakeholders.

Role B – Senior Engineer
You know the legacy system inside out and understand its quirks.
Your goal: Share insights about the system's pain points and suggest practical improvements that won't rock the boat.

Role C – Junior Engineer
You're new and eager to contribute, but you need some direction to navigate this legacy beast.
Your goal: Learn fast, share ideas, and ask questions to get up to speed.

Role D – Product Manager
You're dealing with the heat from stakeholders worried about system reliability.
Your goal: Make sure the team’s efforts match business priorities and keep stakeholders in the loop.

Suggested Openers

Technical Lead:

  • “Thanks for joining, everyone. Our legacy system’s acting up, and we need to sort it out. Let’s nail down some quick fixes and plan for the long haul.”
  • “I’m looking for ideas on how we can make immediate improvements without causing disruptions.”

Senior Engineer:

  • “The database is a real bottleneck right now. We could optimize some of the queries and maybe archive old data to ease the load.”
  • “I’ve pinpointed a few areas where small tweaks could really help. Let’s focus on those first.”

Junior Engineer:

  • “I’m ready to dive in wherever I can help. Could someone guide me on what to start with?”
  • “I’d love to get familiar with the system’s architecture. Any pointers on where to look first?”

Product Manager:

  • “Stakeholders are concerned about reliability. How should we explain what we’re doing to fix things?”
  • “We need to prioritize fixes that align with business goals. What’s our first target?”

Sample Roleplay in Action

Technical Lead:
“Thanks for hopping on, everyone. Our legacy system needs some TLC, and we’ve got to calm down the customer complaints. Let’s figure out what’s dragging us down and how to tackle it.”

Senior Engineer:
“The database is our biggest pain right now, especially during peak times. We could start by optimizing some heavy queries and archiving old data.”

Junior Engineer:
“I’d like to help with the queries. Could you show me where to begin?”

Senior Engineer:
“Absolutely. I’ll walk you through it after this meeting. Also, boosting server capacity temporarily might help us get through peak loads.”

Product Manager:
“Great, I’ll need to keep stakeholders in the loop. Let’s draft a plan outlining our immediate steps and what they can expect.”

Technical Lead:
“Let’s focus on query optimization and data cleanup first. I’ll draft a summary of our plan, and we can review it together before sending it out.”

Product Manager:
“Perfect. Once we’ve got the draft, I’ll update stakeholders to manage their expectations.”

Technical Lead:
“Let’s meet again in a week to see how things are going and tweak our plan if needed. Thanks for all your input.”

Post-Scenario Tools

Curveball Mode (Optional)

Throw one of these in to mix things up:

  • A system outage happens right in the middle of the meeting.
  • Stakeholders demand a detailed timeline for all improvements.
  • A team member suggests a risky overhaul that could disrupt operations.

Reflection Checklist

Common Mistakes to Avoid

  • Overcommitting without a thorough assessment
  • Focusing only on short-term fixes without a long-term vision
  • Failing to engage all team members in the discussion
