Meet Conviwalk Ltd, a fashion brand distributor that consigns with department stores.

The operation involves three scattered data sources, which increases the risk of human errors and lags when delivering consolidated insights. The data sources are:

  • Outlet sales data received via email.
  • Its own system that tracks inventory logistics between factory, head quarter, and outlets.
  • Outlet and head quarter stock opname, which is paper based.

We start with a discovery meeting to identify

  1. Conviwalk Operating model
  2. KPI (what information that management need to monitor)
  3. Existing data source (what data that are available to measure the KPI, and their samples)
  4. Existing tech stack (what infrastructure resources that are already available or need to be acquired as part of the project)

To automate daily consolidation, trend capture, visualization, and alerts, we develop analytic infrastructure that features

  • Automation that fetch sales data from email.
  • Stock opname app for digital transformation from paper works.
  • Automated daily message to management containing high level summaries.
