How dangerous can bugs be? One day a small bug in the Uber application provoked a life drama and a $48 million loss for the company. The app continued popping up notifications even when the application was logged out. Sounds insignificant? Not for one French businessman who was cheating on his wife! Notifications about his routes were sent to his wife’s phone, which he had used to call an Uber the day before. He thought he had logged out of the app on her phone, but alas, the glitch in the app prevented him from completely logging out. The glitch that affected only iPhones is fixed already, but it was impossible to fix the Frenchman’s marriage.

That’s the price of neglecting quality assurance that can cost you a lot. Seeking maximum test case coverage, entrepreneurs might fall for exotic techniques like crowdsourced testing as one of the ways to improve product quality for a fraction of the price. But, does it really work better than a professional QA team? In this article, we’ll talk about the difference between crowdsourced testing and in-house testing teams, and elaborate on the point when crowd testing can be beneficial while highlighting the strength of experienced QA professionals for software development projects.

What is Crowdsourced Testing: The Basics 

Crowdsourced testing is a software evaluation approach that leverages a diverse group of testers, often referred to as the “crowd”, to assess digital products. These testers come from various backgrounds, and locations, and with various devices, offering a wide array of perspectives. 

The process begins by outlining the testing objectives, criteria, and scope, and requires specialized platforms to engage the crowd. Following predetermined test cases and scenarios, crowd testers give feedback on different product aspects like functionality, usability, performance, and compatibility. We can say that this crowd-testing approach replicates real-world usage conditions, providing unique insights that conventional testing methods might miss. At the same time, we need to remember that the qualifications of crowd testers can be different, which can significantly influence the results. 

When we choose outsourced testing, this model involves engaging external resources to fulfill  the company’s requirements. The company delegates the management of certain business processes the quality assurance testing in this case to another specialized company. These processes are executed through formal agreements between the involved companies. In other words, an outsourcing company provides its workforce temporarily to other companies. 

Although outsourced testing eliminates the necessity for a customer to recruit, onboard, and train in-house specialists or ensure the availability of required tools and infrastructure, it’s usually better suited for business needs. At MobiDev, we don’t offer QA as a service, but provide QA services as a part of the development process for our clients, considering outsourced testing as the best strategy for most organizations, as entrusting your testing processes to professionals enables a quicker product launch, and expedites your return on investment.

The outsourcing company you work with may lack a thorough understanding of the client’s business context, making it difficult to balance testing activities with business goals.

Why Crowdsourced Testing May Not Fit Your Project

Outsourced testing and crowdsourced testing are two distinct approaches to software testing. Both have unique characteristics and are suited to different scenarios. So, let’s delve deeper into the differences between outsourced testing and crowdsourced testing. 

The Difference Between Crowdsourced and Outsourced Testing

Overall, a crowdsourced testing approach lies in its ability to tap into a diverse and widespread group of testers, but it still has a range of flaws that can’t be accepted by most companies. Crowdsourced testing can be chaotic and difficult to control, while still requiring qualified people to evaluate the results. 

The main characteristic of outsourced testing is its structured and professional approach. By engaging a specialized third-party organization with dedicated experts, outsourced testing offers a controlled and well-managed environment, ensuring that quality is not compromised. This approach typically includes clearly defined roles, responsibilities, communication channels, tools, and processes. 

Security protocols are stricter, and the entire process can be more easily scaled and managed according to specific project requirements. In addition, the outsourced company often owns the complete testing platform and environment, ensuring consistency and quality throughout the testing lifecycle. This leads to a more reliable and comprehensive evaluation of the product, aligning with established standards and client expectations.

Choosing the Right Testing Approach: What You Need to Know

Crowdsourced testing presents valuable advantages, including diverse testing environments, cost-efficiency, scalability, and flexibility. These benefits contribute to a comprehensive testing process, enabling efficient bug detection, optimal resource utilization, and seamless adaptation to project dynamics.
