“While you can always aspire to additional percentage points of return on assets (ROA) or revenue growth, we have found that eventually the prospects for achieving incremental improvements become vanishingly small; after all, trees don’t grow to the sky. Having achieved top-level performance, the questions then become how to sustain it, and, should that effort fail, how to regain it.” (excerpted from, Exceptional performance: A nonrenewable resource, by Michael E. Raynor, Derek M. Pankratz, & Selvarajan Kandasamy)
