Fast delivery on a slow train – Combination of multiple development approaches

How can you fit the fast subway system on the slow freight train?”

Freight train planning’s are tight scheduled from factory into a shop. A subway is a taken when needed, on an impulse, such as when it rains. In an IT project with multiple development approaches it can feel like connecting the subway timetable on the delivery pipe line between the harbor of Rotterdam with the German hinterland industry.

Our project combines Waterfall and Agile/Scrum development approaches, So I needed as a tester knowledge of both. On a daily basis you need to switch between parallel running releases and decide which strategy to follow. The added value as a tester is if you can make the risks visible, almost touchable. For example is the risk of not be able to deliver a product higher than the risk that an end-user don’t understand the menu structure (and won’t buy a product) or higher than not knowing about app crashes on a group of devices?  The supply chain is developed in a Waterfall and the mobile app with the Agile/scrum approach. So are the risks in the IT systems of the supply chain bigger, more important than the risks of the end-users with the mobile app?

Testing within the dynamic world of mobile apps also need to cope with the development approach of the backend systems, of the logistic supply chain. An innovative (test) approach can show where the risks are and what quality is for the end-user.
