Selected case studies

A concise view of project work across operations, reporting, and customer strategy to show practical business impact.

Process mapping and workflow alignment for a service operation

Description: Mapped the current intake-to-delivery process, identified duplicated handoffs, and documented a clearer ownership flow for daily execution. Tools: Excel, Miro, stakeholder interview notes. Impact: Teams gained a shared view of responsibilities and moved to a more consistent operating rhythm with fewer avoidable delays.

Reporting cadence redesign for clearer weekly decision-making

Description: Reworked a fragmented reporting routine into one weekly pack focused on pipeline health, conversion movement, and operational blockers. Tools: SQL, Excel, and Power BI. Impact: Leadership conversations shifted from reconciling numbers to discussing actions, improving confidence in planning and prioritization.

Stakeholder discovery sprint to align goals and requirements

Description: Ran structured discovery sessions with commercial, operations, and delivery stakeholders to surface assumptions and define shared project requirements. Tools: Interview guides, Notion synthesis boards, and Excel prioritization matrices. Impact: The project began with clearer scope boundaries and stronger cross-team alignment, reducing rework during execution.

Dashboard development for pipeline and performance visibility

Description: Designed an executive dashboard concept that combined sales activity, stage movement, and service outcomes into one decision-ready view. Tools: Tableau, Power BI wireframes, and SQL data checks. Impact: Stakeholders could review trends faster and identify where coaching or process adjustments were needed first.

Customer-journey analysis to improve conversion quality

Description: Audited the journey from first inquiry through follow-up, highlighting friction points in response timing, handoff clarity, and message consistency. Tools: Excel journey mapping, CRM exports, and qualitative call-note review. Impact: Teams adopted clearer follow-up standards and more consistent messaging, supporting stronger trust during early customer conversations.
