Aivana CIO Decision Twin turns user-provided meeting notes, risk registers, budget updates and project reports into concise Executive Decision Packets. It separates evidence from assumptions, compares options, prepares board challenge questions and identifies missing evidence and human approval gates. Start with Board Prep, Crisis, Portfolio, AI Governance or Operating Review. Decision lifecycle guidance helps identify validity conditions, changed assumptions, stakeholder disagreements, reversible experiments and outcome evidence. Twin means a conditional decision model, not an autonomous executive or a complete enterprise replica. This skills-only package uses context supplied to the host. It does not include live enterprise connectors, a hosted backend or automatic external actions. Quantitative analysis, persistent local memory and runtime exports require the separate source repository. Copyright (c) 2026 Aivana GmbH. Distributed under the MIT License.
