Too Much Religion

Programmers are a religious sort, unquestioningly engaging in ritualistic practices pronounced as "good" by the industry's high priests, and likewise shunning those practices branded as blasphemous. Everyone knows for example that mixing business logic with user interface code will damn your soul to Hell for all of eternity. Likewise, engaging in waterfall development leads to nowhere but poverty and pestilence. And each time you use dependency injection, an angel gets his wings.

The religious tenets of our industry of course have mostly arisen from hard-learned lessons about what seems to generally work and what seems generally not to. Still, it is clearly the case that there is no single path to project nirvana. Every development initiative grapples with a unique variety of technical, political, and sociological challenges. Some projects even succeed. It is of course natural that people examine the practices used by the really successful ones, and strive to emulate them to maximize their own chances for salvation.

Successful software development, alas, cannot be achieved by blindly following the prescriptions laid down in some sacred textbook or blog posting. The sacred texts do indeed provide valuable techniques discovered only after the spilling of vast amounts of blood by our ancestors who came down out of their mainframes to spread out across the network, converting green screens to rich clients, and procedures to objects. So, let us embrace the tools and techniques, but let us also recognize that the reason software projects fail is that there is no "Way" that one can simply follow to guarantee success.

Software development projects present us with a series of challenges. Each of those challenges can generally be addressed with some established set of tools and techniques. When we complete a successful project we are typically tempted to look back on the steps we took along the way and announce to our colleagues, "Ah, yes, truly we have found The Way. Let The Way be written down so that it be made repeatably so, and we can look forward to nothing but happy days for ourselves, our managers, and our manager's managers." And yet we then see others try to follow The Way, only to find misery, chaos, and even death. Okay, maybe not death.

So are we condemned then to roll the dice each time we undertake a new development initiative? I don't think so. But the solution is not religion. The solution is in learning a few highly useful techniques, but rather than applying them ritualistically, we should instead learn to assess the particular challenges presented at a particular juncture of a particular project, and to select among and adapt the various techniques to the challenge at hand.

The Way does not exist. This is The Only Way.
