This document discusses customizing Dynamics CRM to track sales pipeline development over time without code. It proposes:
1) Creating a "Process Stage" entity to represent sales stages and use rollup fields to collect open opportunity counts and values for each stage.
2) Creating a "Snapshot" entity to store historical snapshots of the rollup field values using a scheduled workflow to update snapshots weekly.
3) Configuring the scheduled workflow to query Process Stage records and create new Snapshots to track the pipeline trend over time. Charts can then visualize the pipeline development data stored in Snapshots.
