Creating Software Is More Challenging Than You Might Think
Written on
Chapter 1: The Illusion of Simplicity
Many individuals who believe that software creation is straightforward will soon discover that it’s far from easy. The initial perception can be misleading; while software can be viewed as a marketing tool, a website, or a mobile app, the reality becomes complicated once the project is underway.
"If you can't explain it simply, you don't understand it well enough." — Albert Einstein
At a glance, the fundamental requirements of software may resemble a child's simple stick figure drawing—just a few lines and circles. However, once you begin to sketch, you quickly realize that accurately depicting features like faces and fingers demands a much higher level of skill.
People often overlook the intricacies involved in custom software development, forgetting that it’s rarely as uncomplicated as it appears. Hofstadter’s Law serves as a reminder: projects often take longer than anticipated, even when accounting for this tendency.
If software development were as easy as it seems, there wouldn’t be a need for bespoke solutions, and all companies could simply utilize the same software. The reality is, if it were straightforward, the costs associated with software creation would be significantly lower, as specialized expertise wouldn't be necessary. The prevalence of delayed and unsuccessful software projects suggests that the complexity is routinely underestimated while the capabilities of development teams are overestimated.
Section 1.1: The Misunderstanding of Technology
Many individuals believe they have a firm grasp of how various technologies function, from mobile phones to toilets. However, if asked to explain how a toilet flushes, they may either admit ignorance or provide a vague, high-level description that lacks detail.
A recent Gartner survey revealed that 55% of companies regret their IT purchases, hinting at a deeper issue: 67% of those who made these purchases were not IT professionals. Furthermore, a significant number of leaders feel immense pressure to accelerate their digital transformation efforts.
This scenario mirrors the challenges of software creation. Individuals often think they comprehend existing software and how new systems should operate. However, when developers pose specific questions, these individuals frequently realize their understanding is superficial.
The oversimplified high-level view of software misleads businesses into believing that the development process will be smoother than it truly is. As one delves deeper into software requirements, the complexity becomes increasingly apparent, leading to a deeper understanding of the numerous rules, limitations, teams, and functionalities involved.

Section 1.2: The Realities of Software Development
The process of creating software is inherently complex, and anyone who claims otherwise is either misinformed or misleading. While writing code might seem simple, software development encompasses a myriad of challenges. Each line of code interacts with a vast and intricate codebase.
When developers modify one segment of the code, it can be challenging to ascertain whether these changes will inadvertently affect another segment. As the codebase expands, so does the complexity; each additional line compounds the existing challenges.
Managing this complexity is essential to minimize dependencies and mitigate the impact of changes. Prioritizing quality during development is crucial; neglecting this can lead to growing technical debt, which ultimately slows down progress. The larger the project, the more significant the risk of technical debt disrupting the timeline.
Chapter 2: The Challenge of Larger Projects
The first video, Why Are You Making Programming HARDER?, explores the common pitfalls and misconceptions surrounding software development, emphasizing the importance of understanding the intricacies involved.
The second video, The WORST Way to Develop Software, discusses the frequent mistakes made in software projects and how to avoid them.
Section 2.1: The Myth of Quick Development
A common desire among stakeholders is to see software developed quickly, with reduced costs and tight deadlines. However, this is a complex challenge that often requires multiple development teams to work concurrently.
The difficulty of coordinating several teams multiplies the complexity of a project, making it exponentially harder than managing a single smaller project. The analogy of parenting illustrates this well: caring for two children is not merely double the effort; it can feel like four times as challenging due to their differing needs and actions.
Larger projects inherently bring more time, developers, requirements, and complexity, all of which increase the likelihood of encountering issues. To mitigate these challenges, organizations must cultivate strong leadership, skilled developers, and efficient processes.
Section 2.2: The Importance of Local Solutions
As Garrett Hardin discusses in Filters Against Folly, addressing problems locally rather than globally often leads to better outcomes. When problems are approached on a larger scale, ownership diminishes, and accountability can wane.
This phenomenon is similarly observed in software development. As project size increases, individual developers may feel less responsibility, which can lead to conflicts and communication challenges. The more people involved, the greater the need for coordination and decision-making.
Conclusion: Embracing the Reality of Software Development
When embarking on a substantial project, the focus often leans toward how quickly software can be delivered, rather than acknowledging the inherent difficulties involved. Software development is rarely as straightforward as it appears on paper; it demands unwavering discipline and commitment.
Ultimately, developing software is a marathon rather than a sprint. There are no shortcuts, and anyone crafting an overly optimistic timeline will soon learn that creating software is invariably more complicated than anticipated.
