THETA ONEDIGITAL

First cohort Winter 2026/27

Learn to write specs engineers can build from.

Eight instructor-led sessions with labs, a final exam and a portfolio review, taught by someone who does this work inside banks and enterprise programmes every week. You leave with the artifacts you built, not a slide deck.

Who teaches it

Theodor Istratescu, and the work the material comes from.

I've been a business analyst since well before this firm existed, and a contracting technical BA since 2022, mostly inside banks, capital markets and one UN programme. The course is built out of that work: the specs that came back, the integrations that failed at the boundary nobody modelled, and the acceptance criteria that were fine until UAT.

Those are contract engagements I delivered as a technical BA. They are my record, not the Academy's client list. The Academy hasn't run yet, so it has no graduates and no references, and I'm not going to borrow anyone else's.

At Raiffeisen I also ran the technical interviews that hire technical business analysts, and mentored BAs at Qualitance. So this course is built from both sides of the table: the work, and the bar someone has to clear to get the offer.

Who this is for

Three specific people.

A business analyst who writes good documentation and keeps getting asked technical questions in the room they can't answer.

You know the process better than anyone. You don't want to be dependent on an engineer to tell you what's possible.

A PM, PO or delivery manager who owns a backlog and inherited the analysis with it.

Nobody trained you for the technical half; you're doing it anyway.

An engineer moving into analysis.

You can read the system. You haven't had to run a workshop full of stakeholders who disagree with each other, and that's the harder half than it looks.

Don't enrol if

  • You want letters after your name.

    This is not an IIBA certification and doesn't lead to one. The material is aligned to IIBA, BABOK and Scrum; the Academy is not accredited by them and does not claim to be.

  • You want a job guarantee.

    There isn't one, and I'd be suspicious of anyone offering you one for a course.

  • You can't make the sessions.

    Sessions three to seven build on each other and your work is reviewed in front of the group. Missing two of them means missing most of it.

  • You want theory and nothing else.

    Most of the time is spent on your artifacts, and they get critiqued out loud. Some people hate that. It's the part that works.

What changes

What you'll be able to do that you can't do now.

Six things. If you can already do all six, this course is not worth your money.

Read an API contract and challenge it.

Open an OpenAPI spec, find the field your feature needs that the response doesn't return, and write the change request to the team that owns that API. In refinement, not in integration testing four weeks later.

Write acceptance criteria that survive UAT.

The happy path is the easy half and everyone writes it. The half that costs sprints is the timeout, the retry, the partial failure, the empty state, the duplicate submission and the permission the user turns out not to have. That's the half you'll practise.

Draw a data flow an engineer will actually build from.

Which system owns the record, which one holds a copy, what happens when the two disagree, and where the flow crosses a boundary you don't control. You'll also write enough SQL to check a claim yourself instead of waiting three days for someone to run a report.

Model a process in BPMN so it can be implemented, not just presented.

Most process models stop at the happy path and get admired in a steering committee. Yours will carry the exception paths, which is the only part engineering needs from you.

Specify an integration end to end, including what it does when it fails.

Request, response, the error cases, the retry behaviour, whether it's synchronous and what that costs the user standing at a counter waiting for it.

Run a requirements workshop without losing the room.

Get a disagreement resolved in the meeting rather than in an email chain afterwards, and leave with a decision somebody has agreed to own.

This is the ordinary working competence of a technical BA. Almost nobody is taught it. People pick up whichever three of the six their last project happened to need.

The difference in practice

Traditional BA vs technical BA

Seven places where the two roles diverge. Every row is a moment that happens in a normal delivery week.
