Redesign an executive dashboard for C-suite

You are given one C-suite slide that plots regional trends for a single metric as a spaghetti chart. Critique the slide and redesign it into an executive dashboard that is easy to interpret and points toward action. Specify: (a) the precise layout (top-line tiles, trend panels, cohort tables), (b) the 6–8 metrics you would choose for this early-stage B2B chat app (for example, Monthly Subscribed Companies with MoM%, Monthly Subscription Revenue with MoM%, Gross and Net Revenue Retention, First-Response-Time P50/P90, Full-Resolution Rate and Median Time-to-Resolve, CSAT/NPS), (c) how you would make regions comparable (index to 100 at launch, per-company normalization, small multiples with consistent y-axes, rank tables), (d) annotation rules for highlights and thresholds, and (e) visualization guardrails (no dual axes, consistent scales, uncertainty bands for sparse countries). Describe how your design makes small-country trends visible that the spaghetti chart hides.

Overview: This question assesses dashboard design, data visualization, metric selection, and executive-level analytical communication in the context of product and growth measurement. See the complete interview account where this question was originally shared.
