4 software testing methods to catalyze business growth

To understand the essence of software testing, we must see it not merely a process but a pivotal tool in evaluating and enriching business value. While some experts associate it with quality assurance, its scope encompasses an extensive array of functional and non-functional aspects. The pursuit of product or software quality involves the collaboration of various stakeholders, whereas software testing corresponds more to code excellence and performance evaluation. 

According to experts at McKinsey, testing and validation procedures account for 20 to 30% of the total development costs. Software testing methodologies exhibit significant variations between businesses, contingent upon factors such as product type, size, and complexity. In essence, these methodologies focus on assessing the proper functioning of applications, products, or software. 

We present four software testing strategies that can empower your business to appraise software performance, eradicate underlying errors, and foster enhanced value for customers. 

Top strategies for software testing 

When it comes to software, the crux of business value lies in the optimal performance of applications or products. A combined study by Oxford University and McKinsey delved into large software projects, revealing that 66% of them exceeded their budgets, with 33% running behind schedule. This dire situation challenged the very existence of 17% of such projects. However, extensive testing of business applications, whether pre-launch, post-launch, or during maintenance, can significantly mitigate these issues. 

Let us now explore four powerful techniques that will elevate your business value, expand your customer base, and carve a notable market presence. 

• The traditional waterfall method 

As a rule of thumb, the waterfall software testing strategy adheres to a sequential approach. It involves testing various business modules in multiple stages, akin to a top-down model where progress flows steadily from top to bottom, much like a cascading waterfall. This consolidated strategy enables software analysts to thoroughly test the functional performance and overall health of business products and applications. However, caution should be exercised when applying the waterfall approach to dynamic, complex, or substantial projects. 

• The agile methodology: Redefining conventions 

Agile, while not a new methodology, stands as a proven and tested one in software development, spanning from production to quality assurance. Embodying the divide and conquer rule, it deconstructs processes into smaller, quickly iterated partitions, thereby making the product readily available for testing. Agile software testing strategies can be seamlessly integrated into various stages, be it design, development, integration, or maintenance. It thrives best in scenarios where resource requirements are minimal or when operating with limited resources or budgets. 

• Rapid application development (RAD) model 

The Rapid Application Development (RAD) methodology facilitates the simultaneous development of multiple software components. Evolving from the iterative model, it presents an alternative agile-based approach, emphasizing the creation of Minimum Viable Products (MVPs) or functional prototypes based on user requirements. These prototypes later undergo testing, incorporating features and functionalities based on customer feedback. 

• V model: Verification and validation technique 

The verification and validation methodology, colloquially known as the V model, expands on the waterfall strategy discussed earlier. Instead of a top-down approach, it adopts a V-shaped workflow, with each phase of software development corresponding to an identical testing phase. Upon the availability of all requirements, the process commences with requirements verification, followed by code development, culminating in the validation phase. 

Choosing the right testing methodology 

Selecting the most suitable technique to test your business application depends entirely on the unique aspects of your project, including its timeline, flexibility, and desired outcomes. The waterfall method finds its place when project requirements are well-defined and fixed, while the agile testing methodology prevails when product requirements draw motivation from user feedback or require flexible timelines. Alternatively, a hybrid approach can be pursued, amalgamating conventional methods with advanced models to expedite testing across business processes, ultimately yielding greater long-term value.
