The most important project management KPI is the budget. The budget is a top-level view of the cost of a project, including all expenses and revenue. It's important because it shows how well your project is doing financially. The second most important KPI is the schedule performance index (SPI). SPI measures how well you're keeping up with your deadlines and meeting your milestones on time. If you have an SPI of less than 1, it means you're behind schedule for that milestone or deadline. If you have an SPI greater than 1, it means you're ahead of schedule for that milestone or deadline.
It is hard to say which KPI is the most important, because it depends on the type of project. However, there are some KPIs that can be considered as more important than others. One of them is the cost of production. It is a good indicator for how well your project is going and if you need to make changes in order to get back on track. Another one would be quality assurance. If you want to know what your customers think about your product, then you should pay attention to this KPI.
