3 Quality and risk

This chapter covers

How to use quality to set goals for our strategy
What quality is and how to define it
What risks are and how they impact quality
How to identify risks with various techniques
How different risks are mitigated by different testing activities

Now that we’re more familiar with our product, restful-booker-platform, the time has come to start considering our strategy. Specifically, we need to answer the following two questions:

What are the goals we are hoping our strategy will achieve?
How are we going to achieve our goals?

It’s important to clarify these two points before we begin digging into specific testing activities to ensure the work we’re doing is delivering value. Failing to do so will result ...
