Firms that can employ and establish <u>isolating mechanisms</u> are more likely to protect their competitive advantage from being copied and/or eroding away.
Isolation mechanisms:
A company is able to maintain its competitive edge for a longer period of time if it can stop a rival from copying the resource or capability that provides it that advantage. Isolation mechanisms is the name of this technique. For instance, a patent is a legitimate tool to stop imitation.
A firm's objective is to have a prolonged competitive advantage when a resource or capability gives the firm an advantage over competitors for an extended period of time. The industry will determine how long a company can preserve a competitive advantage.
If a business can maintain a competitive edge for a year in a fast-moving field like information technology or quick fashion, it may be quite happy. In an industry with less frequent changes, such as feminine hygiene, a persistent competitive advantage may remain considerably longer.
A sustainable competitive edge cannot be maintained by any company indefinitely. The competition is constantly working to improve its own competitive edge.
