Defect Management – Three Components of Effective Defect Management Systems

Software development teams and software testing teams have many choices of defect management tools to help support their software defect efforts. Selecting and using an effective tool is only part of an overall defect management system.

From a high-level view, defect management systems consist of a combination of some defect management tools or tools and a defect management process. These two main components work together to support each other. Ignore either one, and sub-optimal results can be expected. Below I will provide an overview of a typical defect management process. I will also list the key features to look for in an effective defect management tool. All this information will be useful for you to review. But I would be remiss if I left out one of the most overlooked aspects of software defect management beyond tools and processes, which I will also cover later in this article.

Defect Management Process

High-level steps in a typical defect management process:

A typical defect management process includes the following high-level process steps. When implemented within a specific organization, each of these high-level steps has more detailed standard operating procedures along with policies to fulfill process specifications.

  1. Recognition – This step involves the discovery of a defect. Hopefully, the person who discovered the defect was someone on the testing team. In the real world, this could be anyone including other individuals on the project team, or on rare occasions even the end customer.
  2. Categorization – When a defect is reported, it is usually assigned to a designated team member to confirm that the defect is indeed a defect as opposed to an improvement, or other appropriate category defined by the organization . Once categorized, the defect continues the process to the next step which is prioritization.
  3. First – Prioritization is usually based on a combination of user impact severity, relative repair effort, along with comparisons against other open defects. Depending on the size and structure of the organization, prioritization is often managed by a formal change control board. The priority should be determined with representation from management, the customer, and the project team.
  4. Assignment – Once a defect is prioritized, it will be assigned to a developer or other technician to fix.
  5. resolutions – The developer fixes (resolves) the defect and follows the organizational process to move the fix to the environment where the defect is identified.
  6. testiMony – Depending on the environment in which the defect is found and the fix is ​​applied, the software testing team or customer will usually verify that the fix actually resolves the defect.
  7. breaking – Once a defect is resolved and verified, the defect is marked as closed.
  8. Management Reporting – Management reports are provided to appropriate individuals at regular intervals as defined reporting requirements. Additionally, on-demand reports are provided on an as-needed basis.

Defect Management Tools

Features of a defect management tool:

The following are the core features of a defect management tool:

  • Provides a centralized repository for tracking defects in projects.
  • Provides automatic notifications of resource assignments.
  • Ability to define defect resolution status to streamline your defect management process.
  • Ability to provide management reporting, such as the number of open defects grouped by different criteria such as project open defects, severity, and priority.

The following are some optional features to consider when choosing a defect management tool:

  • Ability to capture other items in addition to defects, such as customer suggestions and project-related issues. Things like customer complaints or suggestions for improvement are often lost if not logged into a centralized system. If other tools are not available, a defect management tool can be used to track these types of items as long as they are easily filtered or logically separated from defects.
  • Ability to support internal and external teams. This feature provides the opportunity to engage external teams and in some situations, customers as appropriate.

Another consideration in choosing a defect management tool includes ease-of-use. Comparing a list of features is useful, but seeing how intuitive a system is for the people who need to use it gives a more concrete understanding of how much training is needed and what the system is well received.

The Missing Component of Software Defect Management

Most discussions on the topic of software defect management focus on defect management processes or defect management tools. That’s where most people stop. There is an additional and often overlooked aspect that is more important than the specific defect management tools or defect management process used. I consider this to be the most critical success factor in software defect management. I call this “Organizational Culture,” which is made up of the shared values, beliefs, and accepted behaviors of the people in an organization. But wait. Before you give in to your sudden urge to stop because this article seems like a sharp turn toward a bland and fuzzy, executive management-level, buzzword-following rhetoric, please read more yet because there is a practical side to it. that you want to know. Getting even a rough understanding of how organizational culture affects software defect management can make the difference between the success or failure of a high-profile project you’re involved in.

From my experience, in many organizations, defects are considered something negative, where blame should be assigned as a way to prevent similar defects in the future. This sounds perfectly reasonable, right? The problem is that just because something seems to make sense on paper doesn’t mean it directly translates to the real world.

Here are two questions to consider. If team members feel that any mistakes they make can be used against them in a performance review that affects their pay or job security, don’t they make mistakes that reduce the number of defects? Likely. But I can assure you that the effects are more negative than having many defects. You want to know what defects you have and you want to know about them as soon as possible.

As is generally understood, the later the defects in the process are identified, the more expensive they will be to fix. If defects are viewed as negative things to be avoided, people may be less exposed to them, and may spend more time on certain tasks trying to avoid defects and subsequently defects. A hyper-focus on avoiding defects may be appropriate for some situations, but for most business settings, an unrealistic focus on perfection can be a fatal flaw that leads to suboptimal performance, which may lead to results that are more negative than other defects. try to avoid.

“Field experience and data from leading research on organizational culture show that most organizational cultures are defensive in nature, where people are punished instead of taught the right ways when they make mistakes,” says Buz McOmber, President of Constructive Cultures, an Atlanta-based organizational performance consulting. “Fearing negative consequences, people quickly learn to cover up their own mistakes, blame them on others, or push for correction as ‘not my job’. , significantly increasing costs of the business and harm operational effectiveness and customer satisfaction. The fear of negative consequences is intensified in difficult economic times, increasing the need to identify these defensive behaviors before they engage in a difficult situation at worst. For the Project Manager, it can be very difficult to regain the trust that is lost when their team is afraid of retaliation for mistakes.” McOmber said.

If you’re serious about an effective defect management system, at the very least you need to have a clear process, effective tools, and a culture that understands that defects are a simple commodity. to do work in the real world. These are not mistakes that should be avoided or covered at all costs.

Conclusion

A defect management system consists of a combination of defect management tools or tools and a defect management process.

Additionally, the effectiveness of a defect management system is influenced by the culture of the organization it operates within. For most environments, it makes sense to use tools and processes that focus on speed in identifying, tracking, and resolving defects. This provides a basis for understanding key cases and making appropriate process improvements. If the culture of the group or organization views defects negatively, people will spend more time trying to avoid defects and will be less likely to report a defect when encountered. This can lead to some defects being identified later in the process, when they are more difficult and more expensive to fix.

Based on my experience, organizations that consider defects as part of the process seem to be able to deliver high quality software faster than organizations that consider defects to be negative events to blame.
