Programs use monitoring data to determine progress toward achieving targets or assess the quality of implementation as to course correct as necessary. Monitoring data can also be used during program implementation to test specific interventions or strategies for program improvement. While these methods can help answer what? (what are the trends over time in effective referrals for community health workers?) and how? (are mobile or paper referrals more effective?), programs are often interested in exploring why they observe these results. Qualitative research methodologies can be used throughout program implementation for improvement and decision-making. This implementation guide outlines Dynamic Qualitative Insights, a methodology developed by PSI to help explore questions during program implementation that require open-ended exploration.
