"People fail to deliver projects on a timely basis because they don't have a system in place to organize their work, GTD or Getting Things Done solves this", paraphased from David Allen's book Getting Things Done. He argues effectively that the widely used To-Do lists are virtually ineffective because they don't account for the work itself require to accomplish the tasks. To-Do lists are institutionalized in productivity products, mentioned in meetings and widely written about in goal setting books but yield very poor results. David Allen set about to change this (other have too).

nozbe.com is a nearly complete implementation of GTD providing projects, next actions, notes and files. It's missing lists and some-day tracking both of which I expect to be added in time. All of this will be explained shortly. The site offers free accounts to manage 5 projects and then various paid plans to increase capabilities and scope. They bill monthly or yearly and as an offering it works well. Now, a bit more about GTD.

    Allen wants all of your tasks, notes, goals, and expectations out of your head and on paper or in this case expressed in the web site. Keeping any details in your head is detrimental to achieving desired results. Any activity requiring more than a few minutes of attention to complete is a PROJECT. Projects are accomplished in a set of ACTIONs. An Action is a step that can be accomplished in a period of time. How much time is just as important as the activity itself. If you can quantify or reasonably guess the time it takes your well on your way to planning and achieving the goal of the project.

    All  Actions  have a context, where or by what means you accomplish it. On the phone, at home, at you computer are examples of context. Specifying context with the Action allows you to group actions together to minimize the gear up and gear down times. This is optional however if used, it boosts the effectiveness of the system.

    Notes can be taken and recorded for Projects so that all loose ends can be accounted for, Files can be attached to the Project so that electronic artifacts can be tracked in keeping with all material related to the project being accounted for.

    What is missing are Lists and Some-day tracking. Lists are a terribly important concept in GTD that provide additional organization. Not To-Do lists, they are more general, allowing notes and files to be grouped into units that relate the items together. Nozbe's current implementation just about eliminates the need but can't completely. Without Lists, it's just a bit less effective.

    Some-day tracking is for Projects that are not important now but may or will be in the future some day. This way you don't have to track the project actively and have it out of your head into a place that you can get back to anytime.

    Nozbe is a solid implementation of GTD, it have a nice array of plans including a free plan that makes trying it very easy and there is copious help to teach you GTD if you don't have experience and help for the cases where you need to bootstrap yourself into the experience.
