In the real world of any software development company, all technical debts are not created equally. As the method in which it creates itself and gets accumulated varies from code to code, estimating the value of each is difficult, and there is no general formula in which it can be quantified. Also, in a world where all codes are created perfectly following the ethical practice and following the set guidelines, there may be no technical debt at all as each of the code would be carefully refactored, reviewed and well written. If there are any design flaws at all, it should be properly and carefully identified, prioritized based on the flaws in it and the effects.
Finite Amount Of Time
The development team is given a finite amount of time to remediate a code, and it is, therefore, difficult to rank such codes according to the flaws present within that stipulated time. There may be some codes which would rarely be executed, and there would not be a strong return on the effort and time invested in fixing such codes. When such new and improved feature is under development and reworked on to rectify the malformed features, it would be of little value. It is universally true even if the code is used extensively.
Concept Of Derived Value
It is, therefore, the derived value of the code is used as an important and significant factor, and this concept helps in the proper understanding, estimation, and payment of tech debt in proper pattern and sequence. Any bad code which does not deliver any key feature are usually not perfect or has the ‘Good Enough’ reason to be refactored and time, as well as money, should be wasted on it. There is a general thumb rule that is followed by all development teams by allocating twenty percent of their time and capacity in addressing, evaluating and managing tech debt.
Apportion Of Quality
It is also important to apportion the quality of the code, and for this purpose, the concept of derived value is the best practice. You must determine which part of the entire code should be of high quality as there is no one particular area which cannot be ascertained. There may be different constituencies of the code which may have derived the different level of value of all the features that any codebase may expose. As there is always uncertainty in such matters, it is not possible to estimate the impact of the themes, but it is required for the stakeholders as well as the development team to be aware of the risk and make the best tech tradeoff.
Different Value Derived
The functionality and good performance of the code help the customers to derive the value, and the development team derives it from the quality design and architecture of the code which enables them to deliver good codes at a considerably high velocity. When the sales team is concerned, they derive the value from the features which are not only new but also provide differentiation in marketing by delivering quality releases with new capabilities.
