Most PMP study guides and training programs offer very similar and limited information on Program Evaluation and Review Technique (PERT). The information is usually sufficient to pass the PMP exam, but isn't detailed enough to get a good understanding of the topic, nor does it offer much practical value on real projects.
I have received numerous requests from people asking me to explain this topic in more depth. So I've spent past several weeks researching this topic. I won’t say that I’m an expert now, but I hope to share the knowledge and learn something from you in the process. As usual, I'll try to present a detailed yet simplified explanation.
Before I go further, let me warn you that some of these articles may be far-far beyond the scope of the PMP exam. These articles are meant for those inquisitive souls, who not just want to pass the exam, but also learn something useful and practical along the way.
This post is simply a cover page for the upcoming articles. Over the course of next several articles, I’ll be covering the topics listed below. Please review the list and let me know if you have additional questions or topics that you would like me to cover.
