The task is to identify the word that does not belong to the group. Consider the options:
- Progression
- Headway
- Forge ahead

We need to compare the meanings of these words:
- Progression: implies moving forward or developing.
- Headway: indicates progress or forward movement.
- Forge ahead: means to move forward with determination.
- Deviant: refers to something departing from the normal or accepted standards.
Upon analysis, "Progression", "Headway", and "Forge ahead" all relate to advancing or moving forward, whereas "Deviant" indicates a deviation or divergence from a norm. Therefore, the odd one out is:
Deviant
