Abstract:
Article attempts to present one of the solutions towards the problem of flawed and delayed product
development. The history behind current most popular product development methodology (waterfall methodology)
is traced, as well the problems that this methodology presents such as calendar risks or high
employee turnover rate. The methodology that was created to solve those issues is gaining a lot of popularity
now, because it offers much more agile way of delivering a software product by splitting the whole development
process into manageable iterations. Customer can change the requirements and adapt the product
to the market changes from iteration to iteration. However, this new methodology (agile methodology)
presents some serious problems as well. This article concentrates tackles the main issue – insurance of the
product quality with each iteration. The solution that is presented by the article revolves around creating
and maintaining a correct test pyramid, with the specific description of all the layers of the pyramid. A small
study was conducted on a sample project, where it was calculated, that test pyramid allowed to decrease
the amount of defects by 25 %.
