What kinds of products are available in the planning and scheduling arena?
Products are available costing anywhere from a few hundred dollars to hundreds of thousands of dollars. The less expensive products essentially replace a pencil and paper and allow manual construction of a Gantt Chart on a computer screen. The more expensive products contain algorithms to automatically generate plans and schedules. It should be noted that there is enormous variability in the capabilities of algorithms in high end packages. You should insist that an expensive tool be demonstrated on their process or one of similar complexity and structure.
