As I was preparing for my exams, I came across the term/topic technical debt as one of the topics under the review topics and this term was seen in one of the class activities. I decided to research on the topic, write a blog post to broaden my understanding for the exams. I came across this blog post that talks about technical debt and chose this blog because the concept has been broken down into topics explaining the term in-depth.

The term technical debt has been described in this blog as well as the good and bad reasons for technical debt. It also explains and gives examples on the various types of technical debt such as Planned Technical debt, unintentional technical debt, unavoidable technical debt, software entropy. It also explains some identifications of technical debt in a project and various ways on how technical debt can be avoided and managed. A youtube video is provided explaining the term as well.

In this blog I learned that although the term may sound like a financial term, it is defined as the deviation of an application from any nonfunctional requirements. Simply, it is a code you have to work on tomorrow because you took a shortcut to deliver it/software today. Technical debt just like in financial terms can have interests which is the difficulty to implement changes and thus needs to be addressed in order to prevent software entropy and risks that may relate to the source code. Teams may delay better coding and certain pieces which are understood by them to impede future development, however, interests may cumulate if these pieces, mediocre codes and known bugs that were left are not resolved.

Technical debts can be identified when code smells are too subtle than logic errors and when there are higher levels of complexities with technologies overlapping each other. Other warnings signs include product bugs that will cause an entire system crash and issues with coding styles.

I learned in Planned technical debt that organizations make an informed decision to generate technical debt knowing and understanding the risks and cost while Unintentional technical debt occurs as a result of poor practices, inexperience with new coding techniques and rollout issues. Unavoidable technical debt is created due to changes in the business and technology that present better solutions hence, making old code obsolete.

One way of managing technical debt is to assess debts and to acknowledge that technical debts exists and share discovery with stakeholders, explaining the importance of paying off technical debt earlier. Technical debt can also be managed by using Agile methodologies that can ensure that teams are working on technical debt.

I hope others find this blog educative as well.
