Both devs and managers are attracted to scrum for two different reasons: - devs like scrum because of the agility of it and the though that they will have more control on how to evolve the product and the code base and have the freedom to architect and develop the way they see it right. - managers like it because it gives them an oversight on how the team is performing and a possibility to have a more accurate estimate the a rule of a thumb. In my opinion scrum stop working when devs think that it's complete freedom and control over the product and/or managers think it is a magical spell to increase team productivity. Another reason that make scrum goes wrong is that religious believe that every rule in scrum manifesto needs to be applied as is so magic can happen, scrum is not a recipe but a guide that need to be adapted to each team, organization and context. Trying to follow the rules religiously will always fail.
