Every time a developer changes code, there is an impact on a system. The more important the change, the more it impacts the test workflow. A small change can improve the software and add valuable functionality, but introduce huge problems for specific modules. This will make the system not better but worse than before.
Failure to consider the consequences of a change can lead to disastrous results. This is why an impact assessment is necessary. Effective impact analysis in software development is what your team should think about before making any changes or adding a new module to a product. Deal with potential problems and side effects before they happen.
Impact analysis helps to recognize the problem even before making a change to a project. So a QA can spend more time on a web usability test instead of researching what caused the problem in the part already tested.
Why are we doing an impact assessment?
Impact analysis is performed before a change is made to the code, a bug is fixed, or a new feature is added or removed. It is done to predict the potential consequences in the system. No professional application testing service organizes a workflow without an impact analysis process. Why?
- Assess the possible side effects of a change.
- Identify areas of a system that may be affected by a change.
How to perform impact analysis in software testing
Here are the main steps of an impact assessment process:
- A team comes together to get information about a change that is going to be made.
- Developers and testers inspect the high-level modules that are going to be affected by the change.
- A team inspects the low-level modules and assesses the impact. Developers can present a separate document covering the full impact of changes for each module.
- A team identifies the positive and negative impacts for each module. What are the advantages and disadvantages of the proposed changes?
- Since all positive and negative effects are discussed, a team can think about how to deal with them and whether they can be accepted or denied. How important are the changes? Should they be implemented? Can the side effects be avoided? How do you get there?
Tracking impact analysis is very important for QA companies and testers. This helps them decide which areas should be tested first and which test cases should be given higher priority. They do regression tests to find problems in the modules that were caused by the impact of the changes.
Let’s see what an impact assessment meeting is
What is an impact assessment meeting?
A team organizes an impact assessment meeting to discuss the changes. Using this meeting, software testers understand the exact areas to test first to prevent a bug from appearing in production. During the meeting, the team will discuss the potentially impacted areas of the product and the reasons for this. Usually the meeting is conducted by either a tester or a developer. For example, if a developer is going to add a new module to a product, they should notify the testers to ensure that they are checking particular modules to avoid a bug in production.
In short, if developers add a new module to the product, they should notify testers in advance of which modules may be affected. At the same time, a product manager can also speak from their experience about what they think will be impacted by the change. Thus, an impact assessment meeting is a process in which everyone involved discusses the functionality of the system that could potentially be affected by the change. If you need help, international software testing services like the Testfort testing company help you in this process by providing a specialist or a whole QA team, sufficiently qualified and experienced in the field.
The main idea of impact analysis is to have a clear vision of the potential effects that a change can have on a product. Developers and testers act upstream. They deal with all negative consequences before production. Of course, you can do a project without an impact assessment. But neglecting it can lead not only to the failure of an entire project, but also to the loss of valuable time a team spends going back and forth to improve issues after a release.
In other words, it makes the work process of QA specialists more efficient, allowing them to focus on usability testing or performance testing instead of looking for issues after every change.
