Top 27 Quotes & Sayings by Steve McConnell

In software, the chain isn't as strong as its weakest link; it's as weak as all the weak links multiplied together.

Even when you have skilled, motivated, hard-working people, the wrong team structure can undercut their efforts instead of catapulting them to success. A poor team structure can increase development time, reduce quality, damage morale, increase turnover, and ultimately lead to project cancellation.

Good code is its own best documentation. As you're about to add a comment, ask yourself, "How can I improve the code so that this comment isn't needed?" Improve the code and then document it to make it even clearer.

Testing by itself does not improve software quality. Test results are an indicator of quality, but in and of themselves, they don't improve it. Trying to improve software quality by increasing the amount of testing is like trying to lose weight by weighing yourself more often. What you eat before you step onto the scale determines how much you will weigh, and the software development techniques you use determine how many errors testing will find. If you want to lose weight, don't buy a new scale; change your diet. If you want to improve your software, don't test more; develop better.

It's hard enough to find an error in your code when you're looking for it; it's even harder when you've assumed your code is error-free.

Trying to apply formal methods to all software projects is just as bad as trying to apply code-and-fix development to all projects.

A typical software project can present more opportunities to learn from mistakes than some people get in a lifetime.

Heuristic is an algorithm in a clown suit. It’s less predictable, it’s more fun, and it comes without a 30-day, money-back guarantee.

The default movement on a software project should be in the direction of taking elements of the software away to make it simpler rather than adding elements to make it more complex.

Good code is its own best documentation.

In my experience, you either have encapsulation and abstraction or you have neither. There is no middle ground.

Engineering is the application of scientific principles toward practical ends. If the engineering isn't practical, it's bad engineering.

It's OK to figure out murder mysteries, but you shouldn't need to figure out code. You should be able to read it.

Motivation is undoubtedly the single greatest influence on how well people perform. Most productivity studies have found that motivation has a stronger influence on productivity than any other factor.

There are no secrets on an successful software project. Both good and bad news must be able to move up and down the ptoject hierarchy without restriction.

A brute force solution that works is better than an elegant solution that doesn't work.

The job of the average manager requires a shift in focus every few minutes. The job of the average software developer requires that the developer not shift focus more often than every few hours.

The trouble with quick and dirty is that dirty remains long after quick has been forgotten.

95% on content and the computer language remains the same.

Software projects fail for one of two general reasons: the project team lacks the knowledge to conduct a software project successfully, or the project team lacks the resolve to conduct a project effectively.

The primary purpose of software estimation is not to predict a project's outcome; it is to determine whether a project's targets are realistic enough to allow the project to be controlled to meet them.

In software, consultants sometimes tell you to buy into certain software-development methods to the exclusion of other methods. That’s unfortunate because if you buy into any single methodology 100 percent, you’ll see the whole world in terms of that methodology. In some instances, you’ll miss opportunities to use other methods better suited to your current problem.

Building software implies various stages of planning, preparation and execution that vary in kind and degree depending on what's being built. [...] Building a four-foot tower requires a steady hand, a level surface, and 10 undamaged beer cans. Building a tower 100 times that size doesn't merely require 100 times as many beer cans.

It's better to wait for a productive programmer to become available than it is to wait for the first available programmer to become productive.

A blanket attempt to avoid mistakes is the biggest mistake of all.

Good visual layout shows the logical structure of a program.

... programming requires more concentration than other activities. It's the reason programmers get upset about 'quick interruptions' - such interruptions are tantamount to asking a juggler to keep three balls in the air and hold your groceries at the same time.
