A corporation has a portfolio of business units when it consists of two or more operating companies, each requiring a separate strategy because they compete in different markets.
While each business unit will typically strive to have a unique competitive strategy, the corporate center will give them a more general strategic assignment to grow, consolidate, turnaround or leave. Corporate investment in each business unit, and the expected future performance, will all be aligned with this specific strategic assignment.
The Strategic Assignment Matrix is an analytical framework for setting the overall strategic objective for each business unit in a corporate portfolio. It is based on a comparison between the current returns achieved by each unit and their potential future performance. The current performance, however measured, is known for each unit, allowing each to be plotted on the horizontal axis, with the expected average return in the middle. Then an analysis of each unit’s potential future performance needs to be made, based on a projection of market attractiveness and the unit’s competitive strength. The resulting position on the vertical axis is both an analytical estimation and a tangible future target. The outcome for each unit will be one of five strategic assignments, with linked room for investment. Ideally, the analysis and conclusions should be jointly agreed on by the corporate center and business units.

The five possible strategic assignments are the following:
