Maintaining harmony between the two

Both documents evolve as a product grows, and keeping them aligned is vital. Requirements may change due to new business priorities or user insights, while specifications may adapt to reflect technical discoveries or updates. If these changes are not synchronized, teams risk creating gaps between what was promised and what gets built.

Maintaining harmony means regularly reviewing both documents together. Updates to requirements should trigger corresponding adjustments in specifications, and vice versa. Shared documentation tools or linked references help track dependencies and prevent misalignment. Treating both as living documents ensures continuity across discovery, design, and delivery. This practice reduces rework and keeps teams united around a single, current understanding of the product.
