A great project attracts great people. Be advised that everyone who volunteers to be a part is not necessarily fit for whatever job they would like to do within your organization. When partnering with people you must test their dedication level with small things first.
Ask yourself: How do they respond under pressure?
Does he or she deliver on time?
Does he or she respect your time by submitting high quality work?
Most importantly, why does he or she want a part in what you’re doing?
The answers to these questions will objectively tell you if you have solid team members or dead weight. The people you share your project with will inevitably shape what the project will become. Taking extra time to do multiple jobs correctly is better than having to backtrack and undo damage done. Do yourself a favor upfront and lose dead weight. Make room for the real potential talent your project deserves.
