The «What? Where? When?» principle is well-known in the IT sphere not only by the qa engineers but also other specialists. This principle is a common one and in most cases it allows one to write a good summary and the description of the defect.
While working with the bug-reports one must pay attention to the necessity of writing the summary clearly and shortly. The title itself must contain the information that is enough for the understanding of the essence of the bug at the first glance of it. Such a description helps to understand and reproduce the bug described.
Originally, it appeared due to the word order of the English language. This language is formalized and structuralized so the ability to change the word order is limited. It is similar to the structure of the description of the bug report. The well known sentence structure of the English language is shown below:
- Subject – Who/What?;
- Verb – What is done by the doer?;
- Object – Who/What?;
- Place – Where?;
- Time – When?.
