Design a C-suite executive dashboard in Tableau. Layout: 1. KPI cards showing YoY growth for Revenue, Profit, Customer Count. 2. Geographic heat map of sales by region. 3. Trend line chart with forecast band for next quarter. 4. Top 10 products bar chart with drill-down capability. 5. Interactive filters for date range and business unit. Use a professional color palette (blues/grays) and ensure mobile responsiveness.

Synthesize research literature using systematic evidence mapping. Scope definition: 1. Broad research question suitable for mapping rather than systematic review. 2. Conceptual framework: logic model or theory of change. 3. Inclusion criteria: population, interventions, outcomes, study designs. Search strategy: 1. Comprehensive database searches: PubMed, EMBASE, PsycINFO, ERIC. 2. Grey literature: conference abstracts, government reports, organizational websites. 3. Citation chasing: reference lists of included studies. Screening and data extraction: 1. Title/abstract screening: liberal inclusion at this stage. 2. Full-text screening: apply inclusion criteria strictly. 3. Data extraction: study characteristics, interventions, outcomes, findings. Evidence map creation: 1. Visual representation: heat maps, bubble plots, network diagrams. 2. Dimensions: populations (x-axis) by interventions (y-axis), bubble size=number of studies. 3. Quality assessment: traffic light system for study quality. Gap identification: empty cells indicate research gaps, areas with low-quality evidence need better studies.
