However, an incorrect perception in any of the five areas could create a mindset that limits decision-making process (Malone-Kline, 2008). For example, a known weakness in the areas of Buyer Power, Supplier Power or Threat of Substitution could create the mindset of vulnerability to a Threat of New Entry without recognizing that an extremely high cost of entry (hence high risk) places any new entry in a more vulnerable position (Mind Tools, 2011).
