In software development, decisions carry significant weight. From choosing the right technologies to prioritising features, every move can shape the success or failure of a product. Amidst the hustle and bustle of development, unseen forces often lurk beneath the surface that often goes unnoticed: product debt and sunk cost fallacy.
What is Product Debt?
Product debt is the accumulation of technical inefficiencies, shortcuts, and compromises made during the development process.
Imagine a developer faced with a tight deadline. In their rush to deliver, they take shortcuts, opting for quick fixes instead of long-term solutions. While this approach may yield short-term gains, it accumulates a type of debt known as “product debt.”
This debt manifests in various forms:
- Low-value features that diminish the product’s perceived value, attract the wrong customer base, or complicate the process for both customers and employees.
- Insufficient product documentation, which can restrict the market’s ability to self-serve and, in extreme cases, misrepresent the capabilities and value of the product.
- Failure to track product or feature usage internally, which limits insights into how the market is utilising what has been developed, or even whether it is being used at all.
A study by Stripe found that technical debt alone has a $3 trillion impact on global GDP.
Product debt, much like financial debt, accumulates over time as a result of shortcuts, compromises, and deferred maintenance in the development process. While these issues may seem insignificant in the short term, they can accrue interest over time, leading to decreased productivity, increased maintenance costs, and diminished customer satisfaction.
Product Debt and Technical Debt: The Symbiotic Relationship
Product debt and technical debt are often conflated, but they represent distinct yet interconnected challenges in software development.
Technical debt primarily revolves around coding practices and architectural decisions that prioritise short-term gains over long-term sustainability. This can include rushed implementations, temporary fixes, and suboptimal design choices that accumulate over time, much like the interest on a loan.
On the other hand, product debt extends beyond the realm of code. From incomplete features and outdated dependencies to design flaws and usability issues; product debt impacts every aspect of the software development lifecycle. It represents the cumulative impact of compromises made to meet deadlines, satisfy stakeholders, or simply keep up with evolving requirements.
The two concepts are symbiotic, with technical debt often serving as the foundation upon which product debt is built.
For example, a rushed coding implementation to meet a tight deadline may result in technical debt, but it also contributes to product debt by delivering incomplete or subpar features to end users. A study by McKinsey found that engineers spend 33% of their time dealing with technical debt. As a project manager, this statistic is concerning.
What is the Sunk Cost Fallacy?
The sunk cost fallacy is a cognitive bias that leads individuals to factor in past investments when making decisions about the future. In the context of software development, this bias can manifest in a variety of ways, from persisting with failing projects to doubling down on ineffective strategies.
Consider a project manager overseeing a software initiative. As the project progresses, unforeseen challenges arise, and timelines begin to slip. Faced with mounting pressure to deliver results, the manager grapples with a cognitive bias that leads them to factor in past investments when evaluating future options, often resulting in decisions that perpetuate inefficiency and waste.
More often than not, despite mounting evidence that the project is doomed to fail, stakeholders cling to past investments, rationalising their decision to continue based on the time and resources already spent.
The consequences of the sunk cost fallacy can be particularly dire. It can lead teams to persist with outdated technologies, bloated codebases, or redundant features, all in the name of recouping past investments. But in reality, it only hinders progress and stifles innovation.

The Impact of Sunk Cost Fallacy on Product Debt
In the realm of software development, the sunk cost bias can have significant implications, exacerbating the accumulation of product debt.
Commitment to Ineffective Strategies:
When teams invest substantial resources, such as time, money, and effort, into a particular approach or feature set, they may feel compelled to continue down that path, regardless of its effectiveness. This commitment to an ineffective strategy prolongs the accumulation of product debt, as valuable resources are diverted away from more promising initiatives.
Reluctance to Abandon Projects:
The sunk cost fallacy can also manifest in the reluctance to abandon projects that are no longer viable. Despite clear indications that a project is failing to deliver the desired outcomes or is no longer aligned with business objectives, stakeholders may resist discontinuing it due to the perceived loss of previous investments. As a result, the project continues to accrue product debt without offering any tangible benefits.
Overemphasis on Past Investments:
Decision-makers may become overly focused on recouping sunk costs, leading them to prioritise initiatives that aim to salvage existing investments rather than pursuing more value-driven alternatives. This overemphasis on past investments can impede innovation and hinder the timely delivery of high-quality products, contributing to the accumulation of product debt over time.
Failure to Pivot or Iterate:
In dynamic environments where market conditions and user preferences evolve rapidly, the ability to pivot or iterate on product strategies is essential for success. However, the sunk cost fallacy may inhibit teams from embracing change or exploring alternative approaches, fearing the perceived loss of previous investments. Consequently, product development efforts stagnate, resulting in a proliferation of product debt.
The sunk cost fallacy perpetuates a cycle of suboptimal decision-making in software development, increasing the accumulation of product debt and hindering organisational agility.
How to Avoid Product Debt?
Armed with the right strategies and insights, teams can steer clear of product and technical debt.
Defining Clear and Realistic Goals
At the core of every successful software project lies a clear and realistic set of goals. Without this, teams risk drifting off course, succumbing to frequent changes, rework, and miscommunication. By defining goals that are specific, measurable, and time-bound, teams can maintain clarity, focus, and alignment, ensuring efficient progress towards meaningful objectives.
Following Coding Standards and Conventions
A smooth-sailing development process requires a sturdy codebase built on consistency and quality. Following coding standards and conventions ensures that the code remains readable, understandable, and maintainable, akin to speaking a coherent, unified language. Tools and processes such as code analysis and reviews act as vigilant editors, refining the code and fortifying its longevity.
Implementing Testing and Automation
A critical component of a software product is its reliability and performance, which hinges on robust testing and automation strategies. Neglecting these essential practices can leave projects vulnerable to undetected defects, performance issues, and security vulnerabilities. By implementing comprehensive testing frameworks and automation tools, teams can verify and validate product quality, ensuring smooth sailing for end users.
Managing Dependencies and Documentation
Software projects depend heavily on meticulous management of dependencies and documentation. Outdated, incompatible, or incomplete dependencies can compromise the stability and usability of a product, leading to technical debt. Establishing clear policies and practices for dependency management ensures smooth sailing through turbulent waters, safeguarding against risks and ensuring the resilience of the product.
Monitoring and Measuring Technical Debt
In the realm of software development, the waters of technical debt are ever-present. By monitoring and measuring technical debt, teams can identify and quantify its impact, prioritising and planning its resolution effectively. Through metrics and indicators such as code quality, defect rate, and technical debt ratio, teams gain valuable insights into.
Exploring the Principle of Subtraction: Less is More
In the whirlwind world of product development, there’s a powerful principle often overshadowed by the allure of adding more: the principle of subtraction. It’s the art of streamlining, of trimming away the excess to unveil the essence of your product.
Imagine crafting a mobile app for ordering food. Sure, you could toss in flashy animations and loyalty programs, but does that enhance the core experience? Probably not. Embracing subtraction means zeroing in on what truly matters: a seamless ordering process, tantalising food visuals, and crystal-clear communication with the restaurant.
Think of it like sculpting a masterpiece out of marble. The sculptor doesn’t add more and more marble to create something beautiful; they chip away at the block until the perfect form emerges!
Similarly, in product development, less is often more. By subtracting the non-essential elements, you can create a product that is sleek, intuitive, and laser-focused on delivering value to your users.
Understanding the Principle of Avoiding Assumptions: Dare to Question
Assumptions can quietly sabotage innovation, lurking in the shadows and leading us astray. But what if we dared to question them? What if we embraced a mindset of curiosity and experimentation?
Consider the story of Airbnb. When founders Brian Chesky and Joe Gebbia first launched their platform, they assumed that people would primarily use it to book spare rooms in their homes. However, after conducting extensive user research, they discovered that users were actually more interested in booking entire homes. By challenging their assumptions and listening to their users, Airbnb was able to pivot their business model and unlock explosive growth.
The principle of avoiding assumptions urges us to do the same. Instead of relying on gut feelings or preconceived notions, we should engage with real users, gather empirical data, and validate our hypotheses through rigorous testing and iteration. By daring to question our assumptions, we uncover hidden insights, seize new opportunities, and make more informed decisions.

Respect Failure and Learn from Data: Growth Through Adversity
Failure isn’t defeat; it’s a stepping stone to success. In product development, it’s inevitable but invaluable—an opportunity to learn, adapt, and thrive.
Take Edison’s light bulb journey. Legend has it that he failed over a thousand times before finally succeeding. When asked about his failures, he famously replied,
“I have not failed. I’ve just found 10,000 ways that won’t work.”
Similarly, in product development, we need to respect failure as a natural and necessary part of the journey. Instead of sweeping it under the rug or viewing it as a source of shame, we must embrace it as a source of feedback, insight, and inspiration.
Understanding and Defining Out of Scope: Setting Boundaries for Success
In the fast-paced product world, clarity is key. That’s where the principle of defining out-of-scope comes in. It’s about defining boundaries upfront to manage expectations and ensure success.
Imagine you’re building a website for a client. They want the sun and the moon: e-commerce functionality, social media integration, and a blog. But wait, what about the budget and timeline? By clearly defining what’s out of scope—like budget and timeline constraints—you prevent scope creep and deliver on promises.
Product debt and the sunk cost fallacy are subtle yet powerful forces that can steer projects off course if not carefully managed. By understanding and addressing these concepts head-on, we can avoid the pitfalls of inefficiency and build sustainable, high-quality software.
