From Technical Debt to Technical Health: Strategies for Managing and Reducing Technical Debt

Technical debt is a term used to describe the cost of maintaining and updating software systems over time. It is a metaphor that compares the cost of maintaining software to the cost of borrowing money. Like financial debt, technical debt can be incurred when a short-term decision is made to achieve a quick gain at the expense of long-term sustainability.

There are different types of technical debt:

• Design debt: It refers to the cost of maintaining software that has been poorly designed, making it difficult to understand and change.
• Code debt: It refers to the cost of maintaining software that contains poor quality code, making it difficult to understand and change.
• Test debt: It refers to the cost of maintaining software that has poor test coverage or automated testing.
• Document debt: It refers to the cost of maintaining software that has poor documentation, making it difficult to understand and change.
• Infrastructure debt: It refers to the cost of maintaining software that is running on aging or outdated infrastructure.

Technical debt is not always a bad thing, as it can be used strategically to meet short-term goals, but it should be managed carefully to avoid long-term negative consequences, such as decreased system performance, increased maintenance costs, and reduced ability to adapt to changing requirements.

When inflation is high, the cost of goods and services increases, making it more expensive to maintain and update software systems.

It's important to focus on technical debt during times of inflation and economic downturn because it can have a significant impact on a company's bottom line. When inflation is high, the cost of goods and services increases, making it more expensive to maintain and update software systems. Similarly, during inflation, companies may be facing financial constraints and may not have the resources to invest in maintaining and updating their software systems

Over time, technical debt can accumulate and lead to decreased system performance, which can negatively impact a company's ability to service its customers and generate revenue.

Technical debt can also lead to increased maintenance costs, as it may be more expensive to maintain and update software systems that are poorly designed or contain poor quality code.

Technical debt can also make it difficult to adapt to changing requirements, as it may be more difficult and expensive to make changes to software systems that are poorly designed or contain poor quality code.

Technical debt can also make it difficult to attract and retain skilled workforce, as developers may find it more difficult to work with and maintain software systems that are poorly designed or contain poor quality code.

it's important for companies to focus on managing and reducing technical debt in order to maintain system performance, reduce maintenance costs, and increase their ability to adapt to changing requirements. This can help them to maintain their competitiveness in the market and stay afloat during tough economic times.

A study of over 2,000 software development projects found that technical debt was the number one reason for project failure.

There are several practical steps that can be taken to resolve technical debt:

1. Identify the areas of the software system that have the highest technical debt and prioritise them for resolution.
2. Measure the technical debt in these areas using metrics such as cyclomatic complexity, code coverage, and maintainability index.
3. Refactor the code in the identified areas to improve its design, readability, and maintainability.
4. Increase test coverage to ensure that the refactored code is working as expected and to prevent the introduction of new technical debt.
5. Automate repetitive tasks such as building, testing, and deploying the software system.
6. Improve documentation, including inline documentation, architecture diagrams, and user guides.
7. Establish a code review process to ensure that new code is of high quality and does not introduce new technical debt.
8. Monitor the technical debt over time to ensure that it does not start to accumulate again.
9. Educate the team on the importance of technical debt, best practices for avoiding it, and how to manage it.
10. Allocate budget and resources for regular technical debt reduction activities.

The average cost of technical debt is estimated to be around 20-30% of the total cost of software development.
