I need to manage projects on a regular basis, without ever being a 'project manager' per se - they're not especially complex, only coordinating the work of a few people, lasting 6 months max typically. I've muddled through with my own type of project management tools, typically on excel spreadsheets, but I've not found one good way of doing it, and anything I read on this freaks me out in its complexity with talk of risk registers and the like.
Any suggestions on tools to use that are logical, relatively simple but will help me keep things on track?
