Answer:
5. They have similar strategic resources and strategies.
Explanation:
To have competitive parity among two firms, it is essential that they are trying to reach the same goal, while they are at the same level in achieving that. Also, it is important to only compare firms that can have comparable resources.
For example, it isn't enough just to have a similar customer base to determine a competitive parity among two firms. They have to possess the same strategic goal and resources. In this case, the two restaurant chains have to be of comparable size and presence, with the same strategic goal.
