Project Management: The Numbers Series

Over the next few days, we will publish a few short articles under the label, The Number Series.
The idea is simple: in each post, we will explain a concept with a link to a number, like the Four Dimensions of Project Success, The Three Project Phases, Three Principles for Building a Methodology, etc.
Some of these articles are specific to SUKAD Research and Development work, but others are general concepts.
Today, we will just share the following image. Some information is outdated, but we will update as we write about them. Take a look and soon we will expand on these circles.
