The following excerpt is taken — with a few minor edits — from a white paper I wrote on quality assurance back in the late 1990s for a large corporate client. Given the rather intense coverage of the failings of the Healthcare.gov website — which clearly was not ready for prime time — I thought […]
[From Pitfalls of Modern Software Engineering by Bruce F. Webster (forthcoming)] Categories: managerial The impulse to constantly add new and incremental features to a software program certainly isn’t unique to modern software develoment, or to a particular technology or methodology. It derives largely from three sources. Upper management and marketing want, and sometimes need, those […]
[From Pitfalls of Modern Software Engineering by Bruce F. Webster (forthcoming)] Categories: managerial Let’s start by freely acknowledging that, with rare exceptions, software of any complexity changes between original specification and actual delivery. This is to be expected, and to a certain extent encouraged, when the changes represent a refinement of our understanding of the […]
[From Pitfalls of Modern Software Engineering by Bruce F. Webster (forthcoming)] Categories: political A particular technology or methodology (the “TOM”) is wonderful. At least, you think it is, based on anything from a breathless magazine article to years of experience with solid, successful software development using this TOM. Or you may not think it’s wonderful, […]
The opening of Terminal 5 at London Heathrow Airport has not been without problems, to say the least. And one of the specific problems appears to be the automated baggage handling system: …the computer-operated baggage system has crashed and luggage is now being sorted manually before being loaded on to planes. Twelve return flights to […]
Classic patterns in disputed IT project: Hertz v. Accenture
Just ran across this article at the always-irreverent-but-usually-spot-on Register, an IT news site out of England. The standard patterns of a troubled IT project are so evident in this one report that I may well use it as a case study for my CS 428 (“Real-world software engineering”) class this fall. Here are some of […]
Neverending Story pattern: School District ERP system late, over-budget
A story a few days ago caught my eye, not because it was unusual, but because it follows so familiar a pattern. Here are a few excerpts from the article: MANATEE — Late nights, hefty contracts and humming computers are a norm in the district’s School Support Center, where employees are working to fix a […]
Minnesota DMV software project: Faulty Towers/Neverending Story patterns
In my 2000 white paper, “Patterns in IT Litigation: System Failure (1976-2000)” [PDF], which I researched and wrote while at PricewaterhouseCoopers, I describe six broad fact patterns to classify the types of software system implementation failure. One of those patterns I named “Faulty Towers”: The client buys the system from [or has the system developed […]
![The Meltdown/Spectre CPU bugs: a dramatic global case of the “Unintended Consequences” pattern [UPDATED 4/4/18]](http://bfwa.com/wp-content/uploads/2018/01/intel-cpu-150x150.jpg "The Meltdown/Spectre CPU bugs: a dramatic global case of the “Unintended Consequences” pattern [UPDATED 4/4/18]")
Back in 2000, PricewaterhouseCooper published my research white paper, “Patterns in IT Litigation: Systems Failure (1976-2000)” (PDF). This paper reflected research I and my staff had done over several months on roughly 120 two- or three-party lawsuits involving information technology. I found that almost all of these lawsuits fell into one or two of six […]
