Overview: The retrospective handbook is a useful collection of tips for preparing and running retrospective for agile teams. The central point of facilitating a retrospective is the preparation. All the details - even the smallest details such as how much paper is available or what the colours of the using pens - play an important role in running a successful retrospective. In such preparation, the most important preparation is the relationship. It requires team members to have high trust with each other to address any problems in great details and find the most suitable solution for those problems. My impression: The tips for running remote retrospective would be really useful for anyone especially startups in my opinion. All the startups I have worked for so far have had some foreign teams either external or internal to save operating money. In addition, there are a lot of remote work to save office renting space and almost all of those startups followed the agile method.
