Misconception · MIS:cost-incurred-proves-over-time-control

Mistaken idea “Cost incurred proves over-time control and progress”

Mistaken reasoning: This mistake uses incurred cost first, without establishing an over time criterion or whether the input depicts performance.

Updated Aug 21, 2026 Review due Nov 7, 2026

Why this is mistaken

Establish why control transfers over time before selecting a progress measure. Then test whether the chosen output or input method faithfully depicts transfer and adjust for inputs that distort performance.

Where to watch

When this mistake may appear

  • Half the budget has been spent.
  • Work has started.
Check your work

Your work may contain this mistake if:

  • Skips the over-time pathway.
  • Includes wasted or uninstalled inputs automatically.
  • Never compares the measure with transfer to the customer.
