Software quality:

satisfying the customer’s need

Software quality must be built from the beginning, it is not something that can be added later. For the final product to be of quality, the process by which it is produced must also be of quality.

It is no secret that a lot of software development companies still think that the testing process should be performed at the last stage to consolidate the quality of their product, making a mistake is not a problem if the cost of the error is low, however, the later the errors are detected, the more effort is required to fix them. The possibility of a human error appearing in the software development process is enormous. The identification of risks is of utmost importance, as it will allow focusing on the failures that may materialize in each phase of software development.

The impact of software bugs goes far beyond the cost of fixing them. Reduced revenue, lost market opportunities, incorrectly processed orders, and billing errors are all factors that lose the company money. Hence, customer dissatisfaction is the most impactful cost for software development companies. This situation is much easier to understand when we visualize how a “bug” can grow in the perception of our customers and in the line of costs associated with solving it. Failures in the conception and design phases – for example – could be perceived as errors with a low impact on quality and costs. But when the “bug” is only detected in cycles such as testing or even at launch, its impact is immense.

As exemplified by the following employee in a recent post, which warns about the importance of not allowing bugs to enter production environments. Talking about software quality implies that we have parameters that allow us to establish the minimum levels that a product of this type must reach to be considered of quality. The problem is that most of the characteristics that define software cannot be easily quantified; generally, they are established in a qualitative way, which makes their measurement difficult, since it is necessary to establish metrics that allow to quantitatively evaluate each characteristic depending on the type of software to be qualified.

Achieving quality software is something very complex that implies not only a high qualification of the professionals in charge of the development, but also the existence of quality-oriented workflows by the company. So when we talk about software quality at the enterprise level, we refer to the actions that are taken in a typical way to ensure that quality software is developed in all projects. Quality software involves the use of standard methodologies or procedures for analysis, design, programming, and testing to standardize the work philosophy, to achieve greater reliability and ease of testing, while increasing productivity, both for the development work and software quality control. In summary, software quality is determined by the quality of the process with which it is developed.

Having a defined process and applying improvements to this process, we will be able to increase the quality of our products continuously. Improving software quality is not something that happens once and stays there forever, nor is it a matter of making a drastic change in the development process and then thinking that the quality problem has been definitively solved. It is a matter of understanding quality as the satisfaction of the customer’s needs at the right time and budget, evolving more and more towards a concept of global value provided to the customer in terms of service.
