Become Better at Software Design

Most of the code bases I have seen as a consultant in the past 10+ years had at least some problems with their designs and architectures. Some were actually quite good, with only minor problems. Others were at a point where developers could not do a good job anymore.

Join my Workshop: Clean Software Design & Clean Code to get better at software design.

Here are some articles I wrote about this topic:

  • Simple Design Passes It's Tests Why you need tests to have a good software design.
  • Boilerplate vs. Magic Boilerplate code can be a problem when writing new code, and sometimes when changing code. Magic can be a problem when reading code. You should strive to eliminate both.
  • Smaller Steps Why you should work in smaller steps. And have a save point you can revert to when something goes wrong.
  • 6 Reasons Why You Should Avoid SingletonsThe "Singleton Pattern" has no place in a modern software design. Do not use this pattern when designing software.
  • Changes and Simplicity You will only have a system that is easy to change if your design is really simple.
  • Well Crafted Code, Quality, Speed and Budget Well crafted code will ship faster, and here I explain why. This is basically the reason why you should always pay attention to the design and architecture of your software.

Even small problems in the design and architecture of a system can cost a ridiculous amount of money. So you should try to keep your design and architecture as clean as possible.

Rescue Legacy Code

If you have been working on something significant with a large team for a while now, chances are that you have quite a bit of legacy code lying around now. Your legacy code is valuable to you - It works in production and provides value to your users. On the other hand, it impedes your progress. You need to rescue it...

Here are some articles I wrote about this topic:

Don't let your legacy code slow you down. Don't throw away the valuable stuff in it by rewriting everything - That will take a long time and brings a lot of risk. Try to rescue your legacy code!

Create Higher-Quality Software

Is your quality really as high as you'd like it to be? Even small quality problems can be very expensive. Defects that escape to production cost an incredible amount of money and time. Especially if you factor in the time your users lose and your opportunity cost. Higher quality software is usually cheaper and faster. So you should continuously improve your quality...

Join my Workshop: Clean Software Design & Clean Code to learn how to write higher-quality software.

Here are some articles I wrote about this topic:

"Investments in quality always pay for themselves" - so the saying goes. Well, I think it is not that simple. But investments in quality do pay for themselves when done right.

Improve the Effectiveness of Your Teams

Say you are working with a team of 10 software developers. Every hour lost due to the small inefficiencies in your team costs you between 500 and 1000 Euros. Or even more, if you are in a high-wage area with high office space prices. And there's always the risk of wasting a lot of time by not developing what your users want or by finding a high-impact defect. That's why we want to become more agile and more effective. And that's why you should work hard on removing and mitigating risk...
