A personal Information Manager is miles away from a true Project Management program. Of course, there is Microsoft Project..some people swear by it...some people hate it. I believe you can try it for free by ordering a CD or downloading it.
I use Plan Plus by Franklin Covey..again..you can try it for free:
Again...it's not a project manager..but can be used as such.
When I had Outlook, I did get some use of it's calendering functions...similar to the Plan Plus.
For more traditional project management using a method like GANATT or PERT charts...I can only refer you to google.
Doing a search with PERT or GANATT with project mangement software is sure to bring up many choices.
It all depends on habits and how you manage information.
Some people, although I don't know how they do it, can get by with a simple notebook. Some people can spends a couple hundred on a expensive planner such as Franklin...and just use it as a telephone book. ??? The Franklin Covey system is quite good...although using
and being more effective with it do entail quite a bit of work.
There used to be a shareware program called Mustang...but it doesn't seem to be around these days.
