The Single Source of Truth Rule

The Single Source of Truth Rule holds that an agency should consolidate task tracking into one primary system, because fragmented tools create blind spots in client delivery. When work lives in multiple platforms, ownership becomes ambiguous and deadlines slip. The rule does not demand one tool for every use case; it demands one authoritative record for client-facing work, with specialized tools feeding into it. For example, a designer might use Kloni for local-first mind mapping during concept development, but the resulting tasks must be mirrored into the agency's main platform so account managers can see status. Similarly, an engineering team using Epiq inside Git repositories should sync issue states to the central tracker. The framework matters because retainer profitability depends on visible progress; if a task is not in the single source, it effectively does not exist for delivery oversight. The rule also reduces tool sprawl, which the category description identifies as the primary risk.
