From Weeks to Hours: bridging the gap between business and IT
2026-03-26
What set this apart from design thinking or BPMN courses I've done before was the focus. It was laser-focused on understanding how technology has to serve business processes — and then going further by breaking those processes into segments based on what developers should prioritise, driven by actual business need.

I particularly appreciated that the trainers do not promote a single "correct" approach. Instead, they present multiple techniques, explain the context and trade-offs, and allow us to evaluate what works best for our own scenarios. This is very valuable for making more confident and informed architectural decisions.

The course covers key architectural fundamentals and provides a useful framework for thinking about system design. It helped me better understand how to approach architectural decisions with more confidence and clarity, rather than defaulting to trends or assumptions.
