Understanding Exceptions

In complex planning environments, reviewing every line item is neither practical nor effective. PLAIO is built to highlight exceptions — situations where the current plan deviates from desired or feasible outcomes.

Exceptions direct planner attention to risks, constraints, and imbalances through Exception Management worksheets, highlighted rows in views, and alerts or markers in charts.

What PLAIO surfaces

PLAIO surfaces multiple types of planning exception:

• Inventory falling below safety stock
• Projected stockouts
• Supply arriving too late

Each exception is tied to a specific item, period, and cause, visible through shortage indicators and period-specific warning markers.

Exception context

Exceptions in PLAIO are not isolated flags — they are linked back to the calculations that produced them. Planners can trace:

• Which demand drove the exception
• Which constraint caused it
• Which assumption limits feasibility

This is reachable through drill-down views, linked demand and supply tables, and contextual charts.

Resolving exceptions

When exceptions appear, adjust the relevant inputs — demand forecasts, inventory policies, or lead times — to address the root cause. PLAIO recalculates immediately, showing whether the exception is resolved or whether additional constraints need attention, through updated projections, resolved-exception indicators, and side-by-side comparisons.

PLAIO uses exceptions to reduce noise, focus attention, and support faster, higher-quality decisions. Rather than reacting late, planners can address issues while options still exist.
