 ## Activities
+Process Scheme: [[process.excalidraw]]
+
+### 1. Inception
+- Initiation of the process, based on some necessity or business expectation.
+- At the end, the requirements engineer should be able to describe what is the client vision and return on investment.
+- One must also evaluate if what the client needs is already available in the market.
+
+### 2. Elicitation
+- This activity handles how requirements should be captured.
+- The requirements elicitation techniques must:
+	1. identify the sources of requirements;
+	2. aid the various stakeholders to correctly describe the requirements;
+- This activity is inherently communicational, since it requires an in-depth interaction with the stakeholders.
+- Requirements elicitation techniques:
+	1. Interview
+	2. Survey
+	3. Introspection
+	4. Ethnography
+	5. focus group
+	6. cooperative work
+	7. domain analysis
+	8. object-orientation
+	9. prototyping
+	10. scenario
+	11. goal modelling
