Segmenting businesses

Find the following definition: When businesses profitability, growth, and cash flow complement each other, and add up to a satisfactory overall corporate performance is said to be portfolio management. One benefit of portfolio management is that an organization is in a better position to allocate resources to businesses according to an explicit criteria. A disadvantage would be that it tends to view business segments (business units) as totally independent from one another and this diminishes the potential value of synergy across businesses.
