Consider this problem:
A new system needs to be made, say, some software, and you need to define what it should do. There are different people who are investing in it, who will use it, and others, so you need to interview them all, to understand what they expect from this system.
What topics do you discuss with them, at these interviews?
A common way to start making new systems (software or otherwise), or changing existing ones, is to interview stakeholders – investors, users, and others – to try to understand their expectations; in technical terms, to elicit their requirements.
Requirements elicitation often involves interviews.
One difficulty when preparing interviews, is to decide which topics to cover, and how.
If you let the stakeholders talk spontaneously, they may privilege some topics, and not mention others. Yet it could be that the overlooked information is important.
Corentin Burnay, Stéphane Faulkner, and I attacked this problem by trying to understand what topics stakeholders tend to spontaneously talk about, and which others they tend to discuss only if they are asked.
The result, which is based both on theoretical research and exploratory empirical results, is what we called the Elicitation Topic Map (see below). It shows many topics, and how likely the stakeholders (in our sample) tended to spontaneously share information about them.
In the Elicitation Topic Map, the closer a topic is to the marker “Explicit”, the more likely it will be discussed spontaneously by stakeholders. The closer it is to “Implicit”, the less likely it is going to be discussed, unless the interviewer proactively mentions it and asks questions about it.
The Elicitation Topic Map nicely illustrates that many topics can be overlooked, unless the interviewer is proactive in asking questions on them; these are the topics that stakeholders tend not to talk about spontaneously. It makes sense to prepare questions on them, before going into interviews.
