Every time we have a new colleague, we will introduce our product , our process and even our regulations again and again. Not matter how busy we are, if we don't follow up the new guys' issue immediately, they will think the company is what a mess! So, please do the presentation clean & clear! What? You think it waste too much of your time, right? Yep, I think so too. So, why don't we record a video or make a todo list to solve most of their problems? Since these things are not updated very often, we can keep using the same file for such a long time to do the knowledge transfer. Aw, I know you think Agile doesn't need so many documents. But the question is that if these files can make us work more efficiently, why not?
