To err is human; people learn from their mistakes but can still repeat them. Organisations only learn from people’s mistakes if they find replicable ways to prevent them being repeated.
This requires a learning culture, where people feel psychologically safe to recognise and admit errors. Organisations need to look at how systems and processes support error prevention. This can lead to a fear of standardisation that can hinder creativity and personalisation.
Systematisation doesn't have to mean standardisation, but a framework including design, delivery methods, performance/outcome measurement, continuous improvement processes; all based on evidence, policy, and values – pushing towards organisational vision.
