SYSTEM MAP TO SHOW RELATIONSHIPS

A system map is a visual tool that shows how different parts of a system are connected and affect
each other. It helps you understand cause-and-effect relationships and how changes in one part
can affect the whole system.

A system map is created using the Loopy website: https://ncase.me/loopy/v1.1/.
This website allows designing interactive maps where elements (nodes) influence each
other through positive or negative feedback loops.

KEY COMPONENTS OF A SYSTEM MAP

To understand how a system works, we need to explore its key components and how they are
connected.
Elements: Parts or variables in the system (e.g., CPU speed, software efficiency).

Relationships: How elements affect each other.
Positive (+): One element increases another (e.g., faster CPU Æ better software performance).

Negative (–): One element decreases another (e.g., more programs Æ less memory).
Feedback Loops: Outputs loop back as inputs.
Reinforcing Loop: Amplifies effects (e.g., more users Æ more data Æ better hardware).
Balancing Loop: Stabilises the system (e.g., high CPU temperature Æ cooling system Æ
temperature lowers).

SOLVING PROBLEMS USING SYSTEM MAPS

Example: System Map for Online Account Safety

Problem: Weak passwords, reused logins and ignoring 2FA (two-factor authentication) lead to
many hacked accounts. Build a system map to understand and improve account safety.
Key elements: Password Strength, Use of Two-Factor Authentication (2FA), Number of Accounts.
