Window of opportunity
A window of opportunity (also called margin of opportunity or critical window) is a period of time during which some action can be taken that will achieve a desired outcome or resolve a problem; once the period is over (the "window has closed"), the specified outcome is no longer possible.
Examples include:
- The critical period in the development of an organism, during which neuroplasticity is greatest and key neurological functions, such as imprinting and language, are acquired which may be impossible to acquire at a later stage[1]
- The golden hour or golden time, used in emergency medicine to describe the period following traumatic injury in which life-saving treatment is likely to be successful[2]
- Market opportunities, in which one may be positioned to take advantage of a gap in a particular market[3][4]
- Planting and harvesting seasons, in agriculture
- Space launch and maneuver windows, which are determined by orbital dynamics and constrained by fuel/delta-v budgets[5][6]
- The theorized tipping point in climatology, after which the Earth's climate is predicted to shift to a new stable equilibrium[7]
The length of a critical window may be well known (as in the case of launch windows) or poorly known (in the case of medical emergencies or climate change). In some cases, there may be multiple windows of opportunity during which a goal can be achieved.
In situations with very brief or unpredictable windows of opportunity, automation may be employed, as in algorithmic trading.[8] Real-time computing systems can guarantee responses on the order of milliseconds or less.[9] In some time-critical situations, failure to act may entail a continuously increasing cost over time, or a continuously decreasing probability over time of achieving the desired outcome. This may be represented in real-time computing systems by time-utility functions.
In some cases, critical windows may be deliberately imposed (or even falsely implied) as a marketing tactic to encourage action, in what is known as a "limited time offer".[10]
