Project portfolio management (PPM) is the most contemporary business environment to run project management organization (PMO).  It’s been widely used to demonstrate analytic method and collectively managing multiple projects. Project portfolio management organises a series of projects into a single portfolio of reports that capture project objectives and other critical factors. 

The fundamental objective of Project portfolio management (PPM) is to determine the serialof proposed projects according to the organizational goals and objectives.  Each project within PPM should be according to business requirements an economical strategy of business expansion. 
While at individual project level it is important to know how each project is performing, the impact of each project on the portfolio is just as important. The following questions should be asked:
Does each project contribute to the overall achievement of the portfolio?
How well is each project performing?
Will any project have a negative impact on other projects to come?
What projects in the portfolio are dependent on others?
Will the successful delivery of all projects deliver the desired benefit or outcome?

Working at portfolio level is about working with summary or key data. It is important to avoid information overload. The detail of each project should be kept at the project team level, administered by the individual project managers. Key information should be rolled up and presented at each level within the organisation as appropriate. At executive, VP level you are likely to be providing a summary of performance, progress, a measurement of estimates against actuals and costs.

Within almost all project portfolio management systems there is a project evaluation process. This process is used to evaluate the projects at various points during their lifecycle. At the beginning of each stage, often called a ‘gate’, the responsible party evaluates the business case, asking whether it is still relevant and able to deliver the defined organisational objectives. If the answer is no, then the project should be stopped. This way the organisation can ensure that they stay focussed on delivering a strategy, goal or other defined benefit and that resources are deployed where they will offer the best return.

Project portfolio management asks the following questions:
Are we doing the right things?
Are we doing them the right way?
Are we doing them well?
Are we getting the benefits?

If the answer to any of these questions is no, immediate action is required to bring the portfolio back on track.

These are the key features of a project portfolio management system:
Project evaluation process or methodology.
Cost and benefits measurement.
Progress reporting.
Communication of key project data, for example executive dashboards.
Resource and capacity planning.
Cost and benefits tracking.

Project portfolio management software enables the user, usually management or executives within the organisation, to review the portfolio, which will assist in making key financial and business decisions for the projects.
