How to Review a Fractional CTO's First Technical Decision

Imagine your company chose a supplier to import customer data into your software. Your fractional CTO recommended the service, you approved the cost and the team connected it. A few weeks later, employees are still correcting some imports by hand.

The integration is live, but that fact alone does not tell you whether the decision solved the problem you needed it to solve. Before deciding the recommendation was good or bad, reconstruct what the company expected, what the team actually delivered and what you have learned since the choice was made.

Find the original question. Perhaps your team was spending too much time preparing customer data before onboarding. Perhaps the immediate concern was a supplier contract that was about to end. Those are different problems, even if both led to the same service being selected.

Look for the options considered and the reason for the choice. The record does not need to be long. It should make clear what the team knew, what it assumed and which consequences it accepted at the time. If that record does not exist, ask the CTO and the people involved to reconstruct it together. Mark uncertain details rather than filling gaps with hindsight.

Next, separate recommending an option from approving it. The CTO may have compared the technical approaches while the founder approved the supplier cost and a product lead agreed to a change in onboarding. Check what authority was actually delegated and whether any required approval was obtained.

A recommendation can be technically sound while a commercial commitment remains unapproved. The review should show who owned each part. It should also make it clear who was responsible for moving the approved choice into delivery.

Now follow the decision into the implementation. In the example, the supplier may have been connected only for new customers, or the team may have postponed the rules for handling unusual data. Ask the person who delivered the integration to show what was completed and what remains open.

Then speak with the employees who correct the imports. Find one recent correction and trace why it was needed. Was the data format outside the agreed scope? Did the supplier return an unexpected result? Did the team choose a manual step temporarily because the customer deadline was close? Each answer changes what the company should do next.

Compare the observation with the expectation that informed the decision. If the company expected the new service to reduce manual corrections, establish what you can about that work before and after the change. Use the same kind of task and a meaningful period where possible. If nobody recorded a baseline, say so and start measuring the current work rather than inventing a before figure.

Other changes may have affected the result. A new customer data format, a smaller rollout or a change in staffing can all matter. The decision record helps the team ask a more precise question, but it does not by itself prove that the supplier caused every improvement or problem.

Bring the people who know the work into the review. The CTO can explain the reasoning and any remaining technical assumptions. The delivery owner can show what was built. The product or operations owner can explain how the change affected onboarding. The founder can confirm the budget or customer commitment that shaped the choice.

If the original assumption no longer holds, record what changed and who can decide the next step. The team might extend the integration, change the customer onboarding process or return to the supplier with a specific question. Preserve the earlier reasoning so the new decision can be understood in context.

Do not make this review an exercise in assigning blame for every result. A reasonable choice can produce a disappointing outcome when information changes or an assumption turns out to be wrong. Equally, a favorable result does not show that required approvals or risks were handled well.

If the work was not implemented, review the handoff and the capacity available to carry it out. If the choice exceeded the agreed authority, address that boundary separately. One decision can reveal useful questions about the engagement, but it is not a complete assessment of a technical leader.

Finish with a short record of the original choice, what was implemented, what you observed and what remains uncertain. Name the person responsible for the next action and the event or date that should bring the decision back for review.

In the supplier example, that next action might be to test one problematic data format before paying for a larger change. The point is to make the next decision with the evidence now available while keeping the context of the first one.
