Reframing to Reduce Risk

In my experience some risks for delivering these projects on time and on budget might be identified by a project manager early on in the initial inception phase of the project and might be reviewed at the end of each project, but not much attention is paid to the risks during the life of the project.

Change is Learning: No Silver Bullets or Quick Fixes

My professors taught me structured design and design by contract. Those were supposed to be the silver bullets for programming. I thought I was the only idiot that structure and specification didn’t work for. Why did I have to iterate and increment?
