The E-Business Value Matrix is a strategic planning technique that evaluates initiatives based on two important dimensions: practice innovation and business criticality. Initiatives that are high on both dimensions drive the most competitive advantage. The matrix can be used to assess the characteristics of rule makers, rule breakers, rule takers, and rule shakers. Market dominant players tend not to be rule breakers, while rule breakers are usually new web companies and rule shakers are second- or third-tier companies. The matrix also helps managers evaluate partners and competitors, identify gaps, allocate resources, and monitor the evolution of initiatives over time.
