Step 1: Understanding the Question:
The passage argues that organisations resist change, called structural inertia, and that changing an organisation's core features is disruptive and raises its short-run mortality hazard. We are told that consultants recommend changing the entire configuration, strategy, structure, and systems together, of an organisation. We must judge the effect of such a sweeping change if the passage's ideas are accepted.
Step 2: Key Concept or Approach:
The passage states directly that changes in an organisation's core features are disruptive and increase mortality hazards, at least in the short run. Strategy, structure, and systems are exactly the kind of core features the passage is talking about, so changing all three together is the most extreme version of this disruption the passage describes.
Step 3: Detailed Explanation:
Option 1, that this rejuvenates the organisation, goes against the passage, which treats sweeping core change as disruptive and risky, not restorative.
Option 2, that it aligns the organisation better to its external environment, may be the consultants' intention, but the passage does not say the change will succeed in doing this, it warns instead about the mortality risk the attempt itself creates.
Option 3, that it increases competitiveness by redefining core competence, again assumes the change works out well, which the passage gives us no basis to assume, its concern is with the risk of change, not its eventual payoff.
Option 4, that it increases the organisation's vulnerability, matches the passage directly: changing core features, strategy, structure, systems, is disruptive and raises mortality hazards, which is exactly what increased vulnerability means.
Step 4: Final Answer:
Changing the entire configuration of strategy, structure, and systems together increases the organisation's vulnerability, following directly from the passage's claim about structural inertia and mortality hazards.
\[ \boxed{\text{Increases the vulnerability of the organisation}} \]
