Operating model
01 / Douwyn
One technical point of responsibility throughout the work.
The person clarifying the requirement also shapes the architecture, reviews important decisions, and remains accountable for the handover. Business context stays connected to implementation decisions.
If a workstream needs specialist input, Douwyn identifies who will contribute, their responsibility, and the relevant scope before work begins.
What Douwyn builds
Digital systems connected to how a business operates.
Before defining scope, Douwyn reviews the current workflow, data, operators, required integrations, and how the system will be handed over.
- 01
Business websites
High-performance, multilingual websites with maintainable content operations, CMS, and technical SEO foundations.
- 02
Custom software
Web applications and internal tools designed around specific workflows, roles, and data.
- 03
Management systems
CRM, workflow, and reporting systems with a clear source of truth and appropriate access controls.
- 04
APIs and automation
System integration, less repetitive entry, and failure paths that can be observed and recovered.
- 05
DevOps and cloud
Containers, CI/CD, Cloudflare, monitoring, backups, and controlled release operations.
How the work runs
Reliable systems do not begin with a technology choice. They begin with understanding the work, stating constraints, and preserving a practical handover path.
Reasoned decisions and explicit boundaries.
P2
Build in testable slices
Prioritize work that can be validated early, reducing risk and investment in unproven assumptions.
P3
Keep ownership clear
Data, environments, documentation, and the handover path are considered during design—not after launch.
P4
Make risks and dependencies explicit
Assumptions, third-party services, and out-of-scope work are documented before they affect delivery or operations.
Engagement process
The process scales with the work, while keeping the main control points explicit so implementation does not start before the problem and scope are sufficiently understood.
Each stage ends with a decision that can be reviewed.
- 01
Discover the context
Clarify the outcome, users, current workflow, data, connected systems, constraints, and success criteria.
- 02
Shape the scope
Document deliverables, architecture, dependencies, risks, acceptance conditions, and the release approach.
- 03
Deliver with evidence
Build in small increments, demonstrate early, test the work, and manage change from observed evidence rather than assumptions.
- 04
Handover and operate
Prepare documentation, access, deployment and monitoring procedures, plus the next improvement list agreed within scope.
