Many of the posts above mentioned that often rather than killing a project, it is just placed on hold until circumstances permit it to continue, and I think this is very true, but I also liked how that hm243 and MonicaGoncalves mentioned that another option to Go, Kill or Hold is to change the scope of the project so that it better aligns with current market needs and company strategy. This may be a difficult decision to make, depending on how far along the project is and how drastic the change in scope is, but in the long run it may be quicker and less work to do this than to start a completely new project.
