Why the vision never gets met in most Indian IT Companies?

Leaders, start with a clear sense of purpose and vision. However, because of constant internal and external pressures on short-term delivery the focus is on immediate events and deliverables. This in effect means managing the vision and immediate events, and little in between. For the employees in the company it is a vicious circle of- working on an event, resolving crisis, waiting for the next event (reactive). This leads to continually moving from one crisis to another; they have no control over their time, let alone their destiny. In the process the vision never gets met, further leading to deep cynicism about the vision among the employees.
