Waterfall, what ya fail

Here is an article against the myth of Waterfall Model, which is still commonly used and considered as correct standard in enterprise software development projects in Hong Kong.

Don’t draw diagrams of wrong practices - or: Why people still believe in the Waterfall model

So what's the other method?

Implementing then specificating?
Testing before coding? xD

I'm serious, what's the problem with this method?

Rational Unified Process is much better because it is iterative and incremental.

The main problem is that we cannot practically complete a task in a phase. Software Development needs iterative and incremental process instead of sequential process as Waterfall.

I know that a modified Waterfall Model is added with iteration but it does not solve its sequential process problem.

See detail at http://en.wikipedia.org/wiki/Rational_Unified_Process

As a comment to bernat: Yes, testing before coding is actually a very good practice, even though you mention it as a joke.

See the wikipedia article for more information.

Also, building the architecture as the needs grow is a central agile practice. And most user-centric design approaches emphasize the importance of iterative design with frequent user feedback, which means that you need to implement something in order to refine your specifications.

Hi Tarmo Toikkanen,

Thanks for your opinion. You raised a very good point - Iterative Refinement.

[Event] JManc 2025

I had the opportunity to attend JManc again this year—and once more, it was fabulous. The sessions were organic, deeply technical, and full of insights shared by developers across different domains. Here's my wrap-up from the day, highlighting a few memorable sessions and conversations. 1 Tony Wilson, Manchester 30 Years of Java — Jim Gough’s Retrospective Jim Gough delivered a fantastic keynote on the evolution of Java over three decades. As a Java Champion, his perspective mixed historical insight with a touch of humor and lived experience. Here are some of the milestones he covered: Applets & Early UI: Java’s original fame came from applets—tiny applications that ran inside web browsers.  AWT & Swing: Early GUI development in Java involved the AWT toolkit, later replaced by the more versatile Swing. JavaFX: The modern Java UI framework that succeeded Swing. It was eventually removed from the JDK and spun out as an open-source project. While less commonly used in modern ...

[Event] Shape The Future with Lloyds

I attended the talk called "Shape The Future with Lloyds". It was exciting to see a legacy bank break out of its monolithic shell and dive into Digital Transformation. The Lloyds Bank team shared insights into their journey of innovation; their commitment and the challenges faced in reshaping such a large institution. It was a great reminder of how iterative progress drives change across any industry. A special thanks to David Underwood for not only posting this event but also for sharing his experience in making daily multiple deployments possible; a true marker of transformation in action!

Mathematical Animation Engine

I recently discovered an interesting Python library called Manim . It’s a powerful tool that allows us to create beautiful animations of mathematical concepts and geometric shapes such as polygons, graphs, and functions. What makes Manim even more exciting is that it can be used directly in Jupyter Notebook. This means I can combine code, text, and animation all in one place — perfect for explaining mathematical ideas in a more dynamic and visual way. To try it out, I created a simple example using Manim to illustrate the Fourier Transform , one of my favourite topics from university. With just a few lines of code, Manim can generate smooth, professional-looking animations that show how complex waveforms are built from simple sine components. I’m excited to explore more possibilities with Manim and use it to present other mathematical concepts in a creative and engaging way. 1.
