A good speech is prepared. A good speech has considered a point to make, which elements to highlight, which stories to emhasize, and the order of which all these elements appear. A good speech has been edited, and maybe reviewed by others. A good speech can set for a solumn mood, spark reflection, and is usually memorable. A good speech can draw smiles, and is often an excellent place for saying “Thank you”, or for strengthening desired behaviour.
Maybe the team members take turns on meeting the challenge in preparing a speech, for certain occasions.
Maybe it is the Product Owner or the Scrum Master that wish to say a few words.
In any case – be kind to each other – you’re practising something hard.
