About this Presentation
In Necessary but Not Sufficient: Using the LTP to Close the Gaps Before Implementation, Thorsteinn Siglaugsson examines why a sound technical solution may still fail to produce the expected result. Using an ongoing transformation at Statistics Iceland, he applies the Logical Thinking Process to implementation readiness rather than treating the technical design itself as the primary problem.
Thorsteinn shows how a Goal Tree can define the conditions required for success, how a Future Reality Tree can test whether proposed changes are sufficient and expose missing assumptions or negative consequences, and how a Prerequisite Tree can convert obstacles into a workable implementation sequence. The case surfaces issues such as cross-functional ownership, specialist capacity, workflow standardization, training, trust, and transition time—conditions that do not automatically follow from introducing a technically sound standard.
The session then extends the same logic to AI adoption, demonstrating why organizations should define the system goal, clarify accountability, protect expert review capacity, test causal assumptions and negative branches, and sequence remaining obstacles before rollout. The Statistics Iceland transformation is still ongoing, so the presentation focuses on improving the quality of implementation preparation and reducing uncertainty rather than claiming completed performance results.
What Will You Learn
To help you get the most value from this session, we’ve highlighted a few key points. These takeaways capture the main ideas and practical insights from the presentation, making it easier for you to review, reflect, and apply what you’ve learned.
Thorsteinn Siglaugsson’s central argument is that a technically correct solution can still fail if the conditions required for implementation are missing. In the Statistics Iceland case, the Logical Thinking Process is used not to redesign the technical solution, but to uncover assumptions, missing enabling conditions, unresolved obstacles, and organizational dependencies before they become implementation failures.
Thorsteinn shows why the Goal Tree, Future Reality Tree, and Prerequisite Tree should not be treated as interchangeable diagrams. The Goal Tree identifies what must be true for success, the FRT tests whether the proposed changes are sufficient to produce the intended effects and exposes possible negative branches, and the PRT converts implementation obstacles into necessary intermediate objectives and sequence.
One of the most important readiness findings was that technical adoption depends on organizational ownership and protected expert capacity. The FRT surfaced two implementation conditions that the new standard itself could not provide: someone must own the end-to-end transformation across technology, people, and process, and specialists must have explicit time released from ongoing production to map, redesign, test, and adopt the new flow.
The same readiness logic applies directly to AI implementation. Thorsteinn extends the case to show that a capable AI model is necessary but not sufficient: organizations still need agreed definitions, validation rules, ownership, review criteria, trained users, governance, and bounded pilots. The model itself is not the implementation plan.
