Learn BA · Lesson 1 of 5 · Northstar

Start with a question worth answering.

Business architecture helps you connect how a business works to the decisions it needs to make. Start with one question, then build only the understanding that helps answer it.

Meet Northstar.

Northstar maintains and rents commercial equipment across 48 branches. Its customers need their equipment working when their own jobs require it. Missed and changed service promises disrupt that work.

The executive request

“Build us a capability map and tell the Council whether the proposed scheduling platform fixes our service-promise problem.”

There are two requests here: produce a map and judge a proposed solution. Before doing either, the business architect needs to make the decision clear.

Turn the request into a decision.

What should Northstar commit to next to improve dependable service promises? The platform is one possible response. Better information, changed operating practices, or a smaller integration might also help.

The Investment Council decides what to fund. Avery, the business architect, connects the evidence, compares options, and makes a recommendation. The architect does not acquire the Council’s authority by drawing a model.

What you will learn

We will connect the customer outcome to business abilities and information, use those connections to challenge a solution, and draft a short decision frame. Then we will follow the same case through investment, readiness, and results.

What does a business architect contribute?

A shared picture of the business that makes dependencies, boundaries, assumptions, and decision rights visible. The useful test is whether that understanding changes scope, priority, ownership, risk, or a choice.
