Here's the introduction of Steve McConnell's "Rapid Development" from 1994 - well before the Agile Manifesto! - Chapter 1, page 1:
> The product manager told me he wanted to build a product right for a change. He wanted to pay attention to quality, prevent feature creep, control the schedule, and have a predictable ship date.
> When the time came to actually do the project, it became clear tha getting the product to market quickly was the only real priority. Usability? We don't have time. Performance? It can wait. Maintainability? Next project. Testing? Our users want the product now. Just get it out the door.
> This particular product manager wasn't the manager on just one product. He could have been almost any product manager I've worked for. This pattern is repeated day after day, state by state, all across the country. ...
This is as far from building a bridge as you can get. The next page of the book starts:
> [1.1] What is Rapid Development?
> To some people, rapid development consists of the application of a single pet tool or method. To the hacker, rapid development is coding for 36 hours at a stretch. To the information engineer, it's RAD - a combination of CASE tools, intensive user involvement, and tight timeboxes. To the vertical-market programmer, it's rapid prototyping using the latest version of Microsoft Visual Basic or Delphi. To the manager desperate to shorten a schedule, it's whatever practice was highlighted in the most recent issue of Business Week.
Agile drew from earlier methods ("intensive user involvement", "rapid prototyping") which were pretty common even before Agile.
