1. Kahneman is relevant for public procurement. I agree with Peter Smith and we are just scratching the surface in what concerns bias/heuristics in public procurement.
2. Majority of OECD countries support social objectives with public procurement but fewer measure outcomes. Every time I ask supporters of social objectives to show me the numbers and underlying data proving whatever benefit is claimed, all I hear back is silence. Not to talk about what downsides have been found or trade offs done.
3. Zambia adopts e-procurement system to curb corruption. It is a step but a lot more will be needed to effectively curb corruption in public procurement.
5. The e-invoicing Directive could (can?) be much better. I agree with most of the comments.
