Disadvantages of Value Based Management

What are the disadvantages of Value Based Management? VBM Drawbacks??

As often the case, the drawbacks or disadvantages of Value Based Management are the opposite of its benefits.

VBM is an all-embracing, holistic management philosophy, often requiring culture change. Because of this, large-scale VBM initiatives take considerable time, resources and patience to be successful.
Value creation may sound more simple than corporate strategy, but it isn't. It is actually more or less the same.
Measuring for value, performance management and balanced scorecard are very powerful management support tools and processes, but have a cost of their own so it is not advisable to go to deep in detail or use metrics that are over-complex.
Extreme caution must be made not to measure the wrong things as this may almost certainly lead to value destruction.
VBM requires strong and explicit CEO and executive board support.
Comprehensive training and consulting support is advisable or even necessary, but can be quite costly.
The perfect VBM or valuation model has yet to be invented. No matter which one you choose, there will always be drawbacks to consider.
