There Acceptance testing is the type of testing performed by a potential customer in order to confirm their decision to accept the product. Though it’s crucial for customers in the first place, this type of testing is often overlooked.
To advocate the importance of acceptance testing, let’s consider the following arguments.
1. Specific and strategic products cannot be checked against the common practice.
When a business is going to purchase or rely on some component or service, a danger of the product’s failure arises compromising the business itself. One of the approaches to handling this problem is making the herd solution, or adopting the framework of some reputed or advertised popular product to ensure you’ll be okay. Many businesses do it with file-sharing services, smartphones and ruggedized laptops frequently and get good results.
But what if these companies were advising some large company on a potential adoption of some product or service which is going to be used and relied upon by hundreds of employees? And what if this deliverable has been built or customized specifically for them? This is precisely the time when acceptance testing can’t be ignored.
2. The Service level agreement cannot guarantee the product’s proper work for sure.
When relying on the vendor’s promises, you should take into account a couple of things.
First, your vendor can’t promise you total satisfaction as the level of its service in the contract is usually specifically and narrowly drawn. It means if you forget about anything that matters and fail to put it in the contract, the thing won’t be covered. That’s why you need acceptance testing that is exactly the process which will help you explore the service’s dimensions that matter.
Second, a timing issue can also interfere. Ignoring acceptance testing, you risk having no time to prevent a disaster when you find that you’d been already deploying the product in full before you discovered the problem with it. You’ve probably negotiated remedies for such a case, but any remedy has practical limitations. For example, a small vendor may not fix their product as quickly as expected. On the other hand, a large vendor may not want to drag the feet on your fixes.
3. Acceptance testing protects customers and makes vendors take the product’s quality seriously.
Acceptance testing should be performed by the customer since only the buying party has got the incentive for proper testing. The testing should not pre-planned or pre-agreed in any detail, because otherwise the vendor is sure the product is going to pass that specific test. To ensure the product really meets its requirements generally, acceptance testing has to be unpredictable.
The vendor needs your money. Thus, if your vendor is hungry and your business is large enough, they will definitely move mountains to get the deliverable work well when they see that you care.
Creative acceptance testing performed by skilled team of testers keeps vendors on their toes and benefits customers greatly.
