The critical research of project management found that many PERT-based models are not suitable for today's multi-project enterprise environment. Most of these models are suitable for large-scale, one-off and unconventional projects.

As a one-off and unique social activity, projects are everywhere in all activities of our human society. It can even be said that all the existing material and cultural achievements of mankind were initially realized through projects, because the existing facilities and conditions on which various operations depend were initially built or developed through project activities.
The purpose of project management is to ensure that the project objectives or indicators clearly put forward by all interested parties are met or exceeded, and to meet the potential needs and pursuits not clearly defined by all interested parties.
The uniqueness of project management lies in that project management is different from the general enterprise production and operation management, and also different from the conventional government and unique management content, which is a completely different management activity.
Projects (more precisely, tasks) that use complex models will lead to unnecessary costs and low operability in many cases.
