Problem Solving Process
Understanding the Problem-Solving Process
Effective problem-solving is at the heart of success in any field. Drawing inspiration from the book “General Relativity for Babies” by Chris Ferrie, which simplifies complex topics into easy-to-understand concepts, I have created a straightforward guide to the problem-solving process.

Level of information need
Ever feel like you’re drowning in BIM data you don’t need, or scrambling for details that should’ve been there? Enter the concept of Level of Information Need. It’s a straightforward idea buried behind a not-so-straightforward name (looking at you, BS EN ISO 7817-1:2024). In plain English, a Level of Information Need defines exactly what information should be delivered – no more, no less – for a given BIM use case or project stage.
