Defect prevention is significantly more efficient as well as successful in minimizing the number of defects than software testing, and it is also highly financially efficient to correct errors that are discovered during the early phase of the custom software application development process. Most firms use a DMP that includes Defect Removal, Defect Discovery, and Process Improvement.
Because of the more robust approach and testing, there will be less unstable software on the market.
Defect Management Process Objectives
The following are the several objectives of DMP:
- Prevent the Error
- Prompt Detection
- Reduce the effect
- Correction of the Defect
- Process Enhancement
Before delving into the DMP (Defect Management Process), let’s understand what a bug or defect is.
Defect Management: Life Cycle
Whenever a system produces an output that is different from the original business need, i.e. when there is a variation from the real or initial company requirements, we may say that the framework has a fault.
When the tester runs the test scenarios, they may encounter a circumstance in which the precise software testing result differs from the intended outcome. This difference is known as a Bug.
A Software Bug is essentially a circumstance that does not fulfill the software requirements. A defect is a mistake or weakness in the system that causes it to behave unexpectedly or incorrectly.
To properly manage projects, you must understand how to cope with design and testing, but you must also learn how to cope with flaws.
Consider what would happen if the tester reported the flaws orally and the developer updated the severity of the bug verbally as well. The procedure will become more complex since these faults include all problems such as being corrected and functioning as planned, being fixed yet not functional, being rejected, being delayed, and so on.
A comprehensive Defect Management Life Cycle is required to control and address the defect successfully.
The Defect Management Life Cycle method guarantees that the procedure is consistent and standardized. Throughout the entire lifecycle of a flaw, it progresses through many stages. After a flaw is discovered, it passes through several stages over its existence, which is referred to as the DLC(Defect Life Cycle).
DMC: Defect Management Process
- Defect Prevention
Defect Prevention is the greatest strategy for eliminating faults in the early stages of testing rather than discovering them later and then repairing them. This strategy is also cost-efficient since the cost of repairing problems discovered during the early phases of testing is quite cheap.
However, it is not feasible to eliminate all errors; nevertheless, you can reduce the scale of the bug and the expense of correcting it.
The following are the primary steps in defect prevention:
- Identify Significant Risks: Identify the critical risks in the system that will have a greater impact if they arise during tests or at a later phase.
- Estimate Expected Effect: For each major risk, estimate the economic effect if the risk were to occur
- Minimize predicted impact: When all significant risks have been identified, prioritize the risks that may be damaging to the platform when encountered and endeavor to minimize or eliminate hazards. It decreases the likelihood of cost-efficient financial risks that cannot be removed.
- Deliverable Baseline
When deliverables (systems, services, or documentation) meet their predefined deadline, it is said to be a baseline. The output or deliverables travel from one step to the next in this process, and when the deliverables go from one step to the next, the current flaws in the system are transferred to the next goal or stage.
- Defect Discovery
It is extremely hard to eliminate all faults from software to create it bug-free. However, you may detect errors early on before they can become expensive to the project. We may claim that the fault was identified when it was formally recognized and acknowledged by the software development team. After the study, the defect developer confirmed it as a fault.
The following are the steps associated with Defect Discovery:
- Detecting a Defect: Identify faults before they cause a serious issue for the program.
- Report Defect: When the tester discovers a defect, it’s their obligation to notify the developer that such an issue has been detected and has to be evaluated and repaired.
- Acknowledgment: Once the tester assigns the problem to the developer, it is the obligation of the developer to recognize the problem and proceed to repair it if it really is a genuine defect.
- Defect Resolution:
During the preceding procedure, the tester detected and notified the flaw to the developer. The developer must now proceed with the resolution for the defect.
- Process Improvement
While faults are prioritized and addressed throughout the flaw resolution process, this does not imply that lesser priority problems are unimportant or have no influence on the program. From the standpoint of the process of improvement, all flaws discovered are the same as a severe defect.
Final Words
We must be followed prior to automation software testing and throughout the whole software development life cycle, not only for individual testing or tasks of development.
