• PL decisions unavoidably bound to SE decisions

  - Risk, architecture, COTS, reuse, staffing

• PL features can enable better SE practices

  - 4GLs: Rapid prototyping, evolutionary development

  - Ada: Integration prior to coding via package specifications

• DoD Ada waiver process isolates the PL decision from SE decisions

  Can result in suboptimal, rigid decisions; unevenly implemented

• Commercial best practices enable integration of PL and SE decisions

  - Architecture review boards (AT&T/Lucent, NASA, Citibank)
