Enterprise: Unlike P3, which was a standalone application designed to be used by a single user on a dedicated machine, P6 is designed to facilitate multiple users across a large organization. It is a true multi-tier system, with a database on the back end, an application server in the middle, and a web server to which users can connect through an internet browser client such as Microsoft Internet Explorer or Mozilla Firefox. This means that the system is very scalable, and can support hundreds of users working on thousands of projects with millions of activities. This also means that it can support companies with geographically diverse projects and a workforce spread across the globe.

Project: At its heart, P6 supports projects. But what is a project? In the Project Management Body of Knowledge, a project is defined as a temporary endeavor undertaken to create a unique product or service. (A Guide to the Project Management Body of Knowledge, 4th Edition, The Project Management Institute, 2008). A project can mean different things in different industries, but projects comprise an amazingly large part of the commercial world. Traditionally we think of construction with respect to projects. But making entertainment is also a project. Think of all the people and equipment and coordination required to make a movie, television show, or album. Developing a new drug is a project as well, starting with basic research and moving to clinical trials, government approval, marketing, manufacturing, and distribution. Each of these is a project by itself.

But what matters is this: A project has a scope of work to be done, a timeline for completing the work, and a set amount of resources to do the work. All of these can be measured within the boundaries of the project. P6 allows you to make these measurements, and it gives you the ability to react to these measurements (scope, schedule, and budget) to ensure that your project accomplishes its goals.

Portfolio: With very few exceptions, a project does not stand alone. A studio creates many movies over the course of a year. A pharmaceutical company develops many different drugs. An energy company has facilities ranging from the frigid tar sands of northern Alberta to the tropical coastline of Brazil. When making strategic decisions about what projects to pursue, which ones to pour more resources into, and which ones to halt, you need to see the larger picture. This is the grouping of projects into a portfolio. P6 can handle thousands of projects and has analytical capabilities to roll up information across projects and perform analysis across the enterprise. This allows decision makers to understand their business from a broad perspective, and to take action on that information.

Management: There is an old adage that says: only what can be measured can be controlled. P6 is about planning projects and measuring progress as the project moves forward. Although P6 is very flexible in how it can be used, it is also designed to help you manage projects well. And when used properly, you can maintain a reliable budget, anticipate cash flow and resource usage, and record and react to changes as they arise. What's more, you can bring the various members of the project team together, set standards, and define the right way to run projects at your specific company.
