How One CTO Uses Decision Logs to Stop Repeating Mistakes

Lucas and Luna explore the concept of a decision log — a lightweight practice where engineering leaders document every major technical decision, including the context, alternatives considered, and the actual outcome. Lucas shares a case from a mid-stage fintech where a CTO introduced a decision log after the team accidentally rebuilt a data pipeline three times in eighteen months because nobody remembered why the previous architecture was chosen. They break down what goes into a good entry, how often to review the log, and why the exercise forces clarity in distributed teams. The episode closes with a practical suggestion: start next week with just one decision, write it down in a shared doc, and see what happens. Listeners walk away with a specific, implementable habit that costs nothing and compounds over time. #DecisionLog #EngineeringLeadership #CTO #TechDebt #KnowledgeManagement #EngineeringCulture #TechnicalDecisions #TeamProcess #Fintech #DistributedTeams #TechLeadership #EngineeringManager #Documentation #DecisionMaking #Technology #FexingoBusiness #BusinessPodcast #Leadership Keep every episode free: buymeacoffee.com/fexingo
