Paradigms and principles The ugly truth remains...
Problem: Little knowledge about the
• state of the art in requirements engineering improvement approaches
• state of empirical evidence
Objectives: Explore the publication space
Weapon of choice: Systematic mapping study

RE improvement todayResearch questions
RQ1. Of what type is the research?
RQ2. Which process improvement phases are considered?
RQ3. What paradigms do the publications focus on?
RQ4. Are the underlying principles of normative or of problem-driven nature?

RE improvementConclusions
• “Healthy” distribution of approaches with many concepts
• Most papers focus on activity-based and normative approaches
»Focus on assessment against activity-based best practice norms
»Triggered by “best practice movement”?
»Little known about benefits and limitations of
»available improvement principles
»available paradigms

13
• Explore principles of artefact-based and problem-driven REPI
• Determine reliable measurements of improvement success
• Evaluate improvement principles in comparative manner
Future research
