The development of either mobile applications or software come with two similar but still very distinctive goals, Quality Assurance and Quality Control or QA QC. The development of the application or software is only half of the story. Keeping the application or software afloat once it has launched is the other half.

This is where a lot of developers get pinched. They forget that presenting the application or software is as important as making sure that the application or software function smoothly. The last thing developers would want is for applications to run perfectly during the first try but run into some roadblocks later on.

These hidden roadblocks are why QA QC are so important.

What exactly is Quality Assurance and Quality Control?

Although the two are hard to tell apart since they often work together as QA QC, there is still a significant difference between Quality Assurance and Quality Control.

Quality Assurance

Quality Assurance is making sure that the positive comes out with a positive declaration. This is often done to gain the confidence of the public by assuring that the application or software will work smoothly without any glitches according to the given requests or expectations.

Quality Control

Quality Control, otherwise known as QC focuses on actually identifying any defects. Quality control makes sure that all the techniques, approaches, methods, and other processes are all followed correctly. Basically, Quality Control is about detecting defects and is done after Quality Assurance.

The difference between the QA QC

It is quite easy to confuse the two since they usually go side by side but there is still a significant difference worth noting.

3 things to avoid in the Quality Assurance process

Looking at the Quality Assurance spectrum, there are a few things you might want to stay away from in order to make sure that the application or software will work just fine and avoid certain red flags from Quality Control.

  1. Testing the things that you don’t understand

It’s important to clarify every single detail with customers and make sure that the application or software is both practical and doable. Although some clients, especially those who do not know much about tech, tend to oversimplify certain things, it is important to walk them through the process and clear out any questions or compromise on certain things to make the final product possible.

  1. Testing only the things that you are supposed to test

In the field of Quality Assurance, it is important to test everything out before presenting the final product to Quality Control. It is vital that you go beyond what is necessary in order to spot certain irregularities before passing the application or software off as “all cleared”.

  1. Assuming that irregular behavior equals correct behavior

Things that don’t make sense don’t make sense for a reason and it is very important to understand every single step of the way making sure that it is the correct step or a correct alternative to the function it was designed for.

It’s important to differentiate the different QA QC roles especially if you are working along with a team and not individually. The more complicated the application or software is, the more attention is demanded to uphold the proper Quality Assurance and Quality Control process.

3 things to avoid in the Quality Control process

Just like Quality Assurance, there are also a few things you need to make sure to stay away from in order to deliver a well executed application or software. QA QC go hand in hand and this is why it is important that both sides do their job correctly. 

Here are a few things to stay away from:

  1. Assuming that QC staff and your own supplier are aware of the “known quality issues”

Although the supplier’s quality manual is mostly solid, there are still a few issues that might have occurred the first time. A defect that you might see as unacceptable might in turn be totally normal for both the factory and staff inspecting your product. Communication is the key to make sure that you are all on the same page with what the product should look like.

  1. Forgetting to classify the defects

Although some defects might be minimal for some, others might deem them extremely important. This goes vice versa and a potential major defect could be looked at as either a minor, major, or even critical defect. It is important to note and agree with everyone where the defects are grouped. Classify the defects accordingly in order to allow prioritized correction.

  1. Failing to note the on-site product tests required

There are a few questions under this bracket that should always be asked when testing a certain product:

  • What are the on-site product tests that are required during the QC inspection?
  • What type of equipment (if there are any) is required for the testing?
  • Who will be responsible for providing the testing equipment necessary?

Transparency is important on so many levels and this is why the customer, the developer/s, the Quality Assurance, and the Quality Control should all work together.
