Reuse Misunderstood
Concept (knowledge) Reuse vs Product ReuseBenefits of re-use are not equal across the board, and typically NOT product (document, code, or hardware) reuse — at least at the higher levels. The benefit of “re-use” is problem-space understanding. The curve of re-use benefit is greater at the bottom (component), less so at the top (system)
An invalid understanding of the areas of benefit of re-use often impact top down analysis. Examples: “Pulling up” predecessor programs specs and assuming re-use with out doing top down analysis. Expectation of design migration without analysis of appropriate “fit” into the new problem-space. |
