System Scenario Mapping

System Scenario Mapping visualizes how a system evolves over time under different conditions, revealing potential variations and actor interactions. It helps teams understand system dynamics and identify opportunities for improvement by analyzing actor behaviors across various scenarios.

When to use System Scenario Mapping

Use this method when you need to understand the dynamic relationships within a complex system and identify potential design interventions under varying circumstances. It's particularly useful when exploring how different actors respond to specific triggers or events within the system.

What it solves

Lack of understanding of system dynamics, overlooking potential consequences of design decisions, failure to account for different user behaviors.

How to run System Scenario Mapping, step by step

  1. Identify key scenarios that significantly impact the system's development. (10 minutes)
  2. For each scenario, identify the main actors involved and prioritize those with the most influence. (15 minutes)
  3. Draw connections between actors, representing the exchange flows (information, resources, etc.) that are activated in a sequence of events. (45 minutes)
  4. Extract key considerations related to pain points and opportunities, noting how actors might behave differently across scenarios. (30 minutes)

Materials needed

  • Large paper or whiteboard
  • Markers or pens
  • Sticky notes (optional)
  • Timer

Facilitator tips

  • Encourage participants to focus on a single scenario at a time to avoid overwhelming the process.
  • Remind the group to consider both positive and negative outcomes for each scenario.

Common pitfalls

  • Overcomplicating the graphical representation, losing sight of the core story.
  • Failing to prioritize actors, leading to an unwieldy map.

Variations

  • Use different colored markers to represent different types of exchange flows.
  • Incorporate user journey mapping techniques to add a layer of user experience to the system scenario.

Running it online or hybrid

Use a collaborative whiteboard tool like Miro or Mural to allow participants to co-create the system scenario map in real-time. Ensure clear visual cues and instructions are provided for remote participants.

What it produces

A visual map illustrating the sequence of events, actors involved, and exchange flows within a specific scenario.
