IN another attempt by the project management team leader and or the project management team to categorize and group materials for the purposes of improving overall organization and making the reference materials that may be needed easier to work with, often times the project management team and or the project management team leader chooses to utilize a portfolio concept. In a portfolio, the project management team and or the project management team leader creates a collection of the programs and or projects as well as any additional work that may have taken place that, when grouped together, provide an effective resource for the purposes of providing reference to the improvement of project management and the way that it fits into the predefined strategic business objective. The items that are contained in the portfolio (including all of the programs and projects contained within) do not necessarily have any direct relation to one another, nor are they necessarily independent of one another.
