Technical debt is similar to any financial debt. If you have a loan on your car, or home or a credit card debt for that matter, it won’t affect much to your financial status if you pay off your installments diligently and in time. You can only do this effectively when your debt is under manageable proportions. However, if it crosses the limit and goes beyond your reach, you start to miss payments and have to answer collection calls. Sometimes, to get rid of the debt you have to declare yourself bankrupt as the last option when all remedial measures have failed. Same is with technical debt.
