Lead time in project management is the amount of time between the start of a project and its completion. It is an important measure of project success, as long lead times can result in delays, cost overruns, and reduced customer satisfaction. By carefully tracking and managing lead times, organizations can optimize their projects, ensuring that they are completed on time and on budget. Lead time management involves accurately tracking the time spent on each task, setting realistic deadlines, and taking proactive steps to prevent or resolve potential issues. By working proactively to reduce lead times, organizations can improve customer satisfaction and increase their profits.
