My Experience Running Development at a Startup
The tracers over prototypes advice is a precious one. Having worked for small and large companies, once you have a functional prototype that has been built quickly, managers tend to be very reluctant to let you rewrite the prototype architecture to make it clean. Using tracers you can demonstrate small but important features to the persons involved in the project and when the project will be given the go sign you can work peacefully on the product's architecture.
