The passage around this formula

Let dimensions d include local-platform support, isolation, context fidelity, extensibility, enterprise policy, cloud reproducibility, review ergonomics, latency, and total cost. For organization o , define $S_{oj}=\sum_d w_{od}z_{jd} -\lambda_o C_j-\mu_o R_j$. where $z_{jd}$ is measured product performance, $w_{od}$ local importance, $C_j$ switching and operating cost, and $R_j$ residual risk. A startup and a bank should choose different weights. Scores should come from trials, not feature presence alone.
