What Is Technical Debt? A Complete Guide

You buy the latest iPhone on credit. Turn to fast car loan services to get yourself those wheels you’ve been eyeing for a while. Take out a mortgage to realise your dream of being a homeowner. Regardless of the motive, the common denominator is going into financial debt to achieve something today, and pay it off in future, with interest. The final cost will be higher than the loan value that you took out in the first place. However, debt is not limited to the financial world.

Technical Debt Definition

Technical debt – which is also referred to as code debt, design debt or tech debt – is the result of the development team taking shortcuts in the code to release a product today, which will need to be fixed later on. The quality of the code takes a backseat to issues like market forces, such as when there’s pressure to get a product out there to beat a deadline, front-run the competition, or even calm jittery consumers. Creating perfect code would take time, so the team opts for a compromised version, which they will come back later to resolve. It’s basically using a speedy temporary fix instead of waiting for a more comprehensive solution whose development would be slower.

How rampant is it? 25% of the development time in large software organisations is actually spent dealing with tech debt, according to a multiple case study of 15 organizations. “Large” here means organizations with over 250 employees. It is estimated that global technical debt will cost companies $4 trillion by 2024.

Is there interest on technical debt?

When you take out a mortgage or service a car loan, the longer that it takes to clear it the higher the interest will be. A similar case applies to technical debt. In the rush to release the software, it comes with problems like bugs in the code, incompatibility with some applications that would need it, absent documentation, and other issues that pop up over time. This will affect the usability of the product, slow down operations – and even grind systems to a halt, costing your business. Here’s the catch: just like the financial loan, the longer that one takes before resolving the issues with rushed software, the greater the problems will pile up, and more it will take to rectify and implement changes. This additional rework that will be required in future is the interest on the technical debt.

Reasons For Getting Into Technical Debt

In the financial world, there are good and bad reasons for getting into debt. Taking a loan to boost your business cashflow or buy that piece of land where you will build your home – these are understandable. Buying an expensive umbrella on credit because ‘it will go with your outfit‘ won’t win you an award for prudent financial management. This also applies to technical debt.

There are situations where product delivery takes precedence over having completely clean code, such as for start-ups that need their operations to keep running for the brand to remain relevant, a fintech app that consumers rely on daily, or situations where user feedback is needed for modifications to be made to the software early. On the other hand, incurring technical debt because the design team chooses to focus on other products that are more interesting, thus neglecting the software and only releasing a “just-usable” version will be a bad reason.

Some of the common reasons for technical debt include:

  • Inadequate project definition at the start – Where failing to accurately define product requirements up-front leads to software development that will need to be reworked later
  • Business pressure – Here the business is under pressure to release a product, such as an app or upgrade quickly before the required changes to the code are completed.
  • Lacking a test suite – Without the environment to exhaustively check for bugs and apply fixes before the public release of a product, more resources will be required later to resolve them as they arise.
  • Poor collaboration – From inadequate communication amongst the different product development teams and across the business hierarchy, to junior developers not being mentored properly, these will contribute to technical debt with the products that are released.
  • Lack of documentation – Have you launched code without its supporting documentation? This is a debt that will need to be fulfilled.
  • Parallel development – This is seen when working on different sections of a product in isolation which will, later on, need to be merged into a single source. The greater the extent of modification on an individual branch – especially when it affects its compatibility with the rest of the code, the higher the technical debt.
  • Skipping industrial standards – If you fail to adhere to industry-standard features and technologies when developing the product, there will be technical debt because you will eventually need to rework the product to align with them for it to continue being relevant.
  • Last-minute product changes – Incorporating changes that hadn’t been planned for just before its release will affect the future development of the product due to the checks, documentation and modifications that will be required later on

Types of Technical Debt

There are various types of technical debt, and this will largely depend on how you look at it.

  • Intentional technical debt – which is the debt that is consciously taken on as a strategy in the business operations.
  • Unintentional technical debt – where the debt is non-strategic, usually the consequences of a poor job being done.

This is further expounded in the Technical Debt Quadrant” put forth by Martin Fowler, which attempts to categorise it based on the context and intent:

Final thoughts

Technical debt is common, and not inherently bad. Just like financial debt, it will depend on the purpose that it has been taken up, and plans to clear it. Start-ups battling with pressure to launch their products and get ahead, software companies that have cut-throat competition to deliver fast – development teams usually find themselves having to take on technical debt instead of waiting to launch the products later. In fact, nearly all of the software products in use today have some sort of technical debt.

But no one likes being in debt. Actually, technical staff often find themselves clashing with business executives as they try to emphasise the implications involved when pushing for product launch before the code is completely ready. From a business perspective, it’s all about weighing the trade-offs, when factoring in aspects such as the aspects market situation, competition and consumer needs. So, is technical debt good or bad? It will depend on the context. Look at it this way: just like financial debt, it is not a problem as long as it is manageable. When you exceed your limits and allow the debt to spiral out of control, it can grind your operations to a halt, with the ripple effects cascading through your business.

Symbion Pharmacy Services? Definition of Responsibility

A ?symbion? is an organism in a symbiotic (i.e. mutually beneficial) relationship with another one. In the case of Australia?s giant Symbion Pharmacy Services, this means supplying and delivering over-counter Chemmart medicines to more than 3,000 hospital and retail pharmacies, while remaining mindful of its carbon footprint.

In 1999, the company with the tagline ?life matters? and a desire to be seen as ?a good corporate citizen? decided it was time to measure exactly what it was pumping out from 12 facilities and over 200 vehicles. This was a voluntary decision as even now there is still no carbon emissions law in Australia (although no doubt being a ?first mover? will put the company in a competitive position when this inevitably comes).

Symbion decided to install emission detection devices and connect these to a central monitoring system with the intention of managing what these measured. There were two stages to this process. First, Symbion determined its reporting requirements based on one of its larger warehouses. Following that, it established a carbon footprint for each of its wholly owned and managed facilities. This put it in a position to:

  • Analyse total emissions down to a level of detail where it understood the contribution of each source
  • Use big data management tools to identify carbon hotspots for priority remedial action
  • Inform the affected workforce, explain the monitoring system and keep them in the loop
  • Separately manage energy abatement programs such as lighting and delivery routes

The program also had productivity spin-offs in that it focused management attention on the processes behind the emissions that were ripe for material and system improvements. It also provided marketing leverage. Symbion?s customers are in the wellness business, ahead of the curve when it comes to how emissions contribute to chronic illness, and aware of the cost of this in terms of human capital.

Which Services to Share?

It often makes sense to pool resources. Farmers have been doing so for decades by collectively owning expensive combine harvesters. France, Germany, the United Kingdom and Spain have successfully pooled their manufacturing power to take on Boeing with their Airbus. But does this mean that shared services are right in every situation?

The Main Reasons for Sharing

The primary argument is economies of scale. If the Airbus partners each made 25% of the engines their production lines would be shorter and they would collectively need more technicians and tools. The second line of reasoning is that shared processes are more efficient, because there are greater opportunities for standardisation.

Is This the Same as Outsourcing?

Definitely not! If France, Germany, the United Kingdom and Spain has decided to form a collective airline and asked Boeing to build their fleet of aircraft, then they would have outsourced airplane manufacture and lost a strategic industry. This is where the bigger picture comes into play.

The Downside of Sharing

Centralising activities can cause havoc with workflow, and implode decentralised structures that have evolved over time. The Airbus technology called for creative ways to move aircraft fuselages around. In the case of farmers, they had to learn to be patient and accept that they would not always harvest at the optimum time.

Things Best Not Shared

Core business is what brings in the money, and this should be tailor-made to its market. It is also what keeps the company afloat and therefore best kept on board. The core business of the French, German, United Kingdom and Spanish civilian aircraft industry is transporting passengers. This is why they are able to share an aircraft supply chain that spun off into a commercial success story.

Things Best Shared

It follows that activities that are neither core nor place bound – and can therefore happen anywhere ? are the best targets for sharing. Anything processed on a computer can be processed on a remote computer. This is why automated accounting, stock control and human resources are the perfect services to share.

So Case Closed Then?

No, not quite. ?Technology has yet to overtake our humanity, our desire to feel part of the process and our need to feel valued. When an employee, supplier or customer has a problem with our administration it’s just not good enough to abdicate and say ?Oh, you have to speak to Dublin, they do it there?.

Call centres are a good example of abdication from stakeholder care. To an extent, these have ?confiscated? the right of customers to speak to speak directly to their providers. This has cost businesses more customers that they may wish to measure. Sharing services is not about relinquishing the duty to remain in touch. It is simply a more efficient way of managing routine matters.

When Carrefour Pushed the Right Buttons

Retail giant Carrefour based in Boulogne Billancourt, France is big business in anybody?s numbers. Europe?s #1 retailer opened its first store in 1958 near a crossroads (Carrefour means ?crossroad? in French) and has largely not looked back since then. The slogan for the hypermarket chain with more than 1,500 outlets and close to a half million employees is ?choice and quality for everyone?. Our story begins when Carrefour decided these things belong at home too.

The company implemented a worldwide universal responsibility program firmly anchored on a tripod of goals for environmental, economic and social progress. Its first step was to appoint a five-person project team tasked with liaising with program delegates in all thirty countries in which it operates, and who had responsibility for driving these goals.

The team?s job was to make sure that policies, standards, procedures and key performance areas were common visions throughout Carrefour. By contrast, the local managers? were tasked with aligning these specifics to local conditions in terms of environmental, political and social issues. The project team checked the fit quarterly via video conferences.

The Triple Bottom Line Goals were woven through with Carrefour?s Seven Core Values, namely Freedom, Responsibility, Sharing, Respect, Integrity, Solidarity and Progress. Constant contact was maintained with staff and other stakeholders through ?awareness training? seminars and other dialogues. As the program took hold and flourished, it became evident that the retail giant needed help with managing the constant stream of metrics flowing in.

After reviewing options, Carrefour appointed a software provider to monitor progress against its primary focuses on energy, water, waste, refrigeration, paper, disposable checkout bags, hygiene & quality, management gender parity, disabled people and logistics. This enabled it to track progress online against past performance, and produce meaningful reports.

The Environmental Manager in the Corporate Sustainability Department waxed lyrical when he said, ?We believe that our sustainability strategy and software solution have powerfully improved collaboration, innovation, and overall performance?. He went on to describe how it was helping drive cost down and profitability up, while simultaneously growing brand.

Non-conformance costs can be high and run counter to the imperative to make a profit – while simultaneously ensuring a better world for our children?s children. In Carrefour?s case, having a consultant to measure progress was the key that unblocked the administrative bottleneck. Irish company Ecovaro does this for companies around the world. Click here.
