Dependencies, Platforms, and the Hidden Architecture That Controls Your Speed
A Modern Approach to System Design
Hi, I’m David Pettersson.
I am an enterprise and domain architect with experience across telecom, finance, insurance, and retail.
This site is where I share perspectives on target architectures, service design, and capability-driven transformation.
Much of my writing builds on frameworks such as EDGY by Intersection, TM Forum ODA, and TOGAF — applied to real-world architecture challenges.
My goal is to make complex change more tangible by connecting strategy, capabilities, and technology.
If you’re short on time, start with the curated reading path below.
Start Here – Architecture as Continuous Change
If you’re new to this site, this path explains how to approach enterprise architecture as a system for continuous change — from direction, to structure, to execution.
1. Define Direction: North Star
How strategy becomes a navigational instrument for multi-year transformation.
2. Establish Method: Architecture Operating Model
How EDGY and ADM enable continuous enterprise design.
3. Make It Actionable: The Architecture Playbook
An end-to-end model for translating intent into execution.
4. Build Structural Leverage: Capability Thinking
Why capability maps fail — and how to make them matter.
5. Prove It in Practice: Service & Platform Design
How strategy, architecture, and experience come together.
6. Steer Change: Leading Indicators
How to govern transformation using predictive signals.
