Technical debt is the term used to describe the consequences of poor quality or incomplete work in software development projects. It refers to the implied cost of rework or maintenance that will be required in the future due to skipping or compromising on testing, documentation, design, or other best practices. Technical debt can negatively affect the project velocity, quality, performance, reliability, security, and customer satisfaction. According to the Professional in Business Analysis Reference Materials1, technical debt can be classified into four types:

Deliberate and reckless: This is when the team intentionally chooses to skip testing or other quality measures, knowing that it will create problems later, but without a plan to address them. This is the most harmful type of technical debt, as it can lead to major defects, failures, or breaches that can jeopardize the project or the organization.

Deliberate and prudent: This is when the team intentionally chooses to skip testing or other quality measures, knowing that it will create problems later, but with a plan to address them as soon as possible. This is a common type of technical debt, as it can help the team meet urgent deadlines, deliver minimum viable products, or respond to changing requirements. However, this type of technical debt still requires careful management and prioritization, as it can accumulate over time and become unmanageable.

Inadvertent and reckless: This is when the team unintentionally creates technical debt due to lack of skills, knowledge, or experience, and without realizing the impact of their actions. This is a dangerous type of technical debt, as it can result in poor quality products, low customer satisfaction, and high maintenance costs. This type of technical debt can be prevented by investing in training, coaching, mentoring, and peer reviews.

Inadvertent and prudent: This is when the team unintentionally creates technical debt due to unavoidable factors, such as evolving technologies, standards, or customer needs, and with a plan to address them as part of continuous improvement. This is an inevitable type of technical debt, as it reflects the dynamic nature of software development. This type of technical debt can be managed by adopting agile practices, such as frequent feedback, retrospectives, and refactoring.

Therefore, the correct answer is C. Increased technical debt. By skipping testing, the project manager and the team are creating deliberate and reckless technical debt, which can have severe consequences for the project and the organization. The project manager will need to focus on identifying, measuring, and reducing the technical debt as soon as possible, and avoid making such decisions in the future.
