Earlier this week, I already wrote why we started “Brightest” (read here).
Today I want to give you a few basic but valid reasons why you should incorporate testing in your software development / customisation project:
Why do software testing?
One should always start with the why. Because it defines what we do, how we do it and who can be involved in it. I have summarized some of the clearest and unambiguous statements on why we do software testing.
- It’s cheaper to prevent problems than to repair them.
It doesn’t take a mathematician to calculate the difference in cost of finding a software defect at the end of your system development lifecycle instead of preventing it at the early start. The more near the end, the more expensive.
- Software testing is an investment in quality.
“To invest is to allocate money (or sometimes another resource) in the expectation of some benefit in the future.”
This benefit (ROI) can be measured. In any case!
- Guaranteed success
Software testing is much more than simply verifying functionalities, measuring performance or investigating usability. Software testing has a direct impact on quality.
And whatever you do, quality is always involved.
Studies have shown that 90% of all software development projects are considered as a failure.
“A project is considered a failure when it has not delivered what was required, in line with expectations. Therefore, in order to succeed, a project must deliver to cost, to quality and on time; and it must deliver the benefits presented in the business case “
- Some other important reasons why we test
- Customer confidence depends on the quality that you deliver
- Quality issues can cause a lot of re-work, mostly at the time the necessary resources are already assigned to other tasks
- Prevent criticism and frustration in your organization or from your stakeholders
- Software testing gives you the ability to make objective go/no go decisions
