Ask HN: Product management for solo side projects?
2 by OJFord | 4 comments on Hacker News.
What do you use for 'product management' as it were - thinking about, planning, and designing different features - for your solo (or very small team, no dedicated product people) project? I have ideas and sometimes I make crappy notes, sometimes I just hold onto (or forget) them, I'd like to do something better to allow me to map things out, see how they might relate etc. but the tools I've used or looked at seem too heavyweight for one person, whether in terms of billing or just to use. I like Productboard for example, but it seems overkill (not to mention expensive) for a one man band. So what do you use, or how do you manage without? Thanks.
