Quality Assurance Costs: Actual and Simulated

Actual Project’s Quality Assurance Costs

Volvo Group’s policy did not allow us to publish the real costs of work invested in the project. For the purpose of research, we agreed that the man-hour cost of work by a software developer \(C_{d}\) will be marked as:
\begin{equation} \label{coder}C_{d}=x\\ \end{equation}
In that case, the average man-hour cost of work by a software tester \(C_{t}\) shall be, calculated according to current labor market data rates (wynagrodzenia.pl 2015):
\begin{equation} \label{manhour}C_{t}=0.85x\\ \end{equation}
That means, that when the tester and code developer are working together on bug fixing during the later stages of the project (not in the coding phase), the average cost per man-hour should be:
\begin{equation} \label{testerdeveloper}C_{d+t}=\frac{C_{d}+C_{t}}{2}=0.925x\\ \end{equation}
Other costs, such as infrastructure and hardware, will remain constant for the real-life and alternative (prediction-based) scenario, so they will be omitted.
