The cost of conflicting versions
When your CRM, spreadsheets, and operational tools each hold a slightly different version of the truth, every meeting starts with a debate about whose numbers are correct. That friction is expensive — it slows decisions and erodes trust in data altogether.
What a single source of truth means
A single source of truth doesn’t mean one giant system that does everything. It means clearly defined, authoritative data that other tools reference, so a customer, order, or metric means the same thing everywhere it appears.
Getting there in practice
Reaching it is mostly about agreement and integration: deciding which system owns which data, cleaning and reconciling what exists, and connecting tools so they stay in sync. The payoff is decisions made on shared, trusted information.
